Docusaurus – The Modern Docs Framework
1. What is Docusaurus? [Docusaurus](https://docusaurus.io) is an open‑source static‑site generator focused on documentation. Built and maintained by Meta (formerly Facebook), it lets you create, version, and deploy documentation sites with **zero configuration** or **full customisation** using React, Markdown, and MDX. | Feature | What it means | |--------|---------------| | **Static‑site generation** | Pre‑renders pages to plain HTML → fast loads, cheap hosting. | | **React‑powered** | Use React components inside your docs (MDX). | | **Zero‑config defaults** | `npm init docusaurus` gives you a working site in seconds. | | **Extensible plugin ecosystem** | Add search, analytics, theme tweaks, etc., without touching core code. | 2. Why Developers & Organizations Should Use It * **Speed to ship** – A working docs site is ready after `npm start`. * **Maintainable codebase** – Docs live alongside source code, enabling PR‑driven updates. * **Scalable** – Handles single‑page docs to multi‑version portals with the same build pipeline. * **Community & Vendor backing** – Backed by Meta, with an active ecosystem of plugins and themes. > **TL;DR**: If you already use React or a Node‑based build system, Docusaurus fits naturally and reduces the overhead of maintaining separate documentation tooling. 3. Key Features & Benefits | Feature | Benefit | Example | |---------|---------|---------| | **Built‑in versioning** | Publish docs for each app release; users can switch versions. | `npx docusaurus docs:version 2.3.0` | | **Markdown + MDX** | Write prose in Markdown, embed React components when needed. | See MDX example below. | | **Search (Algolia, Lunr, etc.)** | Instant full‑text search without external services (optional). | `npm install @docusaurus/theme-search-algolia` | | **Blog support** | Publish release notes, tutorials, or team updates side‑by‑side with docs. | `npx docusaurus blog:write` | | **Theming & Customisation** | Override theme files or create a custom React theme. | `npm run swizzle @docusaurus/theme-classic` | | **Plugin ecosystem** | Add sitemap, RSS, Google Analytics, PWA, and more with a single line in `docusaurus.config.js`. | `plugins: ['@docusaurus/plugin-sitemap']` | | **CI/CD‑ready** | Generates static assets (`/build`) – easy to cache on CDNs. | `npm run build && npx serve ./build` | | **Multi‑platform deployment** | Works on GitHub Pages, Azure Static Web Apps, Cloudflare Pages, Netlify, Vercel, etc. | `gh-pages -d build` | | **Internationalisation (i18n)** | Create docs in multiple languages with locale‑aware routing. | `i18n: { defaultLocale: 'en', locales: ['en','fr','zh'] }` | 4. Simplifying Documentation Management 1. **Docs live in the repo** – No separate repository or wiki. 2. **PR‑driven updates** – Docs are changed through normal code review flow. 3. **Automatic linking** – `[@site]` URLs resolve to the site’s base URL, avoiding hard‑coded links. 4. **Consistent styling** – A single theme ensures all pages look identical, reducing UI drift. Typical Workflow ```bash 1️⃣ Create a new page npx docusaurus docs:create my-new-feature 2️⃣ Write Markdown/MDX (edit docs/my-new-feature.md) 3️⃣ Run locally npm start 4️⃣ Open PR → review → merge 5️⃣ CI builds & deploys automatically ``` 5. CI/CD & Deployment Because Docusaurus outputs **static HTML**, any CI system can treat it like a normal build artifact. ```yaml Example GitHub Actions workflow (docusaurus.yml) name: Deploy Docusaurus site on: push: branches: [main] jobs: build: runs-on: ubuntu-latest steps: - uses: actions/checkout@v3 - name: Setup Node uses: actions/setup-node@v3 with: node-version: '20' - run: npm ci - run: npm run build - name: Deploy to Cloudflare Pages uses: cloudflare/pages-action@v1 with: apiToken: ${{ secrets.CF_PAGES_TOKEN }} projectName: docusaurus-docs directory: ./build # Cloudflare Pages offers a generous free tier (up to 500 build minutes per month and unlimited bandwidth), perfect for open‑source docs. No credit‑card is required, and you can preview changes on PRs automatically. ``` Replace the `cloudflare/pages-action` step with `gh-pages`, `Azure/static-web-apps-deploy`, or `Netlify` steps as needed. 6. Versioning Support ```bash Create a new version folder (e.g., v2.0) npx docusaurus docs:version 2.0 ``` * Docusaurus copies the current `docs/` folder into `versioned_docs/version‑2.0/`. * A selector component appears automatically, letting visitors pick the version they need. **Best‑Practice Tips** * **Version only on major releases** – Keeps the version list short. * **Maintain a changelog** – Use the built‑in blog or a dedicated `CHANGELOG.md`. 7. Markdown & MDX * **Markdown** – Perfect for plain text, tables, code fences. * **MDX** – Allows JSX inside docs, letting you embed live components, charts, or interactive demos. ```mdx My Component Demo Here is a live React chart: import { BarChart } from '@site/src/components/BarChart'; <BarChart data={chartData} /> ``` > **When to use MDX?** When you need dynamic UI (e.g., visualising API responses) or want to reuse existing React components. 8. Search Functionality * **Algolia DocSearch** (recommended for large sites) – Free tier for open‑source projects. * **Lunr.js** – Zero‑config, client‑side index for smaller docs. ```js // docusaurus.config.js – Algolia example themeConfig: { algolia: { appId: 'YOUR_APP_ID', apiKey: 'YOUR_SEARCH_ONLY_API_KEY', indexName: 'your-site', contextualSearch: true, }, }, ``` 9. Blog & Documentation Features | Area | What Docusaurus Provides | |------|---------------------------| | **Blog** | Markdown‑based posts, RSS feed, pagination. | | **Docs** | Sidebar auto‑generation, version dropdown, edit‑URL links back to source. | | **Pages** | Free‑form React pages (`src/pages`). | | **Internationalisation** | Language switcher + per‑locale routes. | 10. Customisation & Plugin Ecosystem * **Theme Swizzling** – Override any component by copying it into `src/theme`. * **Official Plugins** – `@docusaurus/plugin-content-docs`, `@docusaurus/plugin-content-blog`, `@docusaurus/plugin-google-analytics`, etc. * **Community Plugins** – `docusaurus-plugin-sitemap`, `docusaurus-plugin-pwa`, `docusaurus-plugin-openapi`. Quick Custom Theme Example ```bash npx docusaurus swizzle @docusaurus/theme-classic Navbar ``` Edit `src/theme/Navbar/index.js` to add a custom logo or extra navigation items. 11. Integration with CI Platforms | Platform | Typical Integration | |----------|--------------------| | **GitHub** | Use GitHub Actions to run `npm run build` → `gh-pages` deploy. | | **Azure DevOps** | Add a pipeline step calling `npm run build` and publish the `build/` folder to an Azure Static Web App. | | **Cloudflare Pages** | Push the `build/` directory to a Cloudflare Pages project; automatic preview URLs on PRs. | *All integrations rely on the same static artifact (`/build`).* 12. Real‑World Use Cases | Company | Use‑case | |---------|----------| | **Meta** | Internal product documentation for React Native and Jest. | | **Microsoft** | Docs for VS Code extensions, hosted on GitHub Pages. | | **Airbnb** | Public API reference & design system docs with versioning. | | **Open‑Source Projects** (e.g., TensorFlow.js, Storybook) | Community‑maintained docs, searchable, with a blog for release notes. | 13. Comparisons with Traditional Approaches | Traditional Docs (e.g., MkDocs, Jekyll) | Docusaurus | |----------------------------------------|------------| | **Static‑only** (no React) | **React + MDX** – interactive demos possible | | **Limited versioning** | Built‑in versioning via CLI | | **Plugin ecosystem** | Rich, officially supported plugins + community | | **Zero‑config start** | `npm init docusaurus` gives a complete site instantly | | **TypeScript support** | Full TS in custom components and config | 14. Best Practices & Recommendations 1. **Keep docs in the same repo** as the code they describe. 2. **Use versioning** for every public release. 3. **Leverage MDX** for component demos; avoid over‑using React in simple prose. 4. **Enable Algolia DocSearch** for larger sites (free for OSS). 5. **Add a “Edit this page” link** – `editUrl` in `docusaurus.config.js` encourages community contributions. 6. **Automate deployment** in your CI pipeline – a single `npm run build && deploy-step` is enough. 7. **Monitor bundle size** – Docusaurus ships a default theme (~200 KB gzipped); prune unused plugins for faster builds. 15.

How to Add a Module in the ABP.io Application?
If you’re building your application with ABP.io, you’re already on the right path to creating scalable and professional software. One of the best things about ABP.io is how it supports modular architecture. But what does that really mean? In simple words, a **Module** in ABP.io is like a complete feature package. It comes with its own logic, database setup, APIs, and even user interface parts. Think of it as a plug-and-play part of your application that keeps your code clean, reusable, and easy to manage. ABP.io provides many useful built-in modules like Identity, Tenant Management, and Audit Logging. These help you quickly add common features without writing everything from scratch. But sometimes, you need to go beyond the default options. Maybe your project has unique requirements. That’s when creating a **custom module** becomes important. In this guide, I’ll show you how to add a custom module, like **Vineforce.ProjectManagement**, into your existing ABP.io application. You’ll learn how to do it step by step on both the backend using .NET and the frontend using Angular. Whether you’re just starting with ABP.io or already have experience, this blog is made to help you integrate modules smoothly and with confidence. What You’ll Learn in This Guide * How to prepare your system for module integration * How to add the module to your ABP.io backend using NuGet * How to configure the database context and migrations * How to link the Angular frontend with the module using npm * Common pitfalls to avoid during integration Step 1: Prerequisites & Setup Before you begin, make sure the following tools and environments are set up properly. 1.1 Required Software * .NET SDK (compatible with your ABP.io version) * Node.js and npm * Angular CLI (installed globally) * ABP CLI (installed via dotnet tool) * Visual Studio or Rider for .NET * Git for version control 1.2 ABP.io Application Ready Ensure you have an existing ABP.io application up and running. The application should be in either Modular Monolith or Microservice architecture. Step 2: Backend Integration Using NuGet (C# / .NET) We’ll start by connecting your backend application to the custom module using NuGet packages. 2.1 Add Required Packages "Vineforce.Admin.HttpApi.Host"   - [Vineforce.ProjectManagement.Application](https://www.nuget.org/packages/Vineforce.ProjectManagement.Application) - [Vineforce.ProjectManagement.HttpApi](https://www.nuget.org/packages/Vineforce.ProjectManagement.HttpApi)  2.2 Register Module Dependencies 1. Open the file `AdminHttpApiHostModule.cs`. 2. Add the module dependencies inside the `[DependsOn]` attribute: ```csharp [DependsOn( typeof(ProjectManagementHttpApiModule), typeof(ProjectManagementApplicationModule), typeof(ProjectManagementEntityFrameworkCoreModule), typeof(ProjectManagementDomainSharedModule) )] ```  3. Also, add the using statements at the top: ```csharp using Vineforce.ProjectManagement; using Vineforce.ProjectManagement.EntityFrameworkCore; ``` 2.3 Add Required Packages "Vineforce.Admin.EntityFrameworkCore"   1. Also, add the using statements at the top: ```csharp using Vineforce.ProjectManagement.EntityFrameworkCore; ``` 2.4 Update Your DbContext 1. Open `AdminDbContext.cs`  2. Inside the `OnModelCreating` method, add:  ```csharp builder.ConfigureProjectManagement(); ``` This step tells your database context to load and apply table configurations from the ProjectManagement module. 2.5 Apply Migrations Once you update the DbContext, run EF Core migrations to apply the updated schema to your database. Option A: Using Terminal / PowerShell ```bash cd src/Vineforce.Admin.EntityFrameworkCore dotnet ef migrations add Add_ProjectManagement_Module dotnet ef database update ``` Option B: Using Visual Studio (Recommended for Beginners) 1. Open Package Manager Console. 2. Set Default Project to `Vineforce.Admin.EntityFrameworkCore`. 2. Run the Following Commands: ```powershell Add-Migration Add_ProjectManagement_Module Update-Database ``` At this point, the new tables from the module will be added to your main database.  Step 3: Frontend Integration Using npm (Angular) Once the backend is configured, let’s integrate the Angular frontend with the module. 3.1 Install the Angular Module 1. Open your Angular project root (usually `/angular`). 2. Run this command in the terminal: ```bash npm i @vineforce-modules/project-management ``` 4. You can view this link to copy the command: '[@vineforce-modules/project-management](https://www.npmjs.com/package/@vineforce-modules/project-management)' 3. This will also add the following entry in `package.json`: ```json "@vineforce-modules/project-management": "^9.0.0" ```  3.2 Update the app-routing.module.ts File  ```typescript { path: 'project-management', loadChildren: () => import('@vineforce-modules/project-management').then( m => m.ProjectManagementModule.forLazy() ), }, ``` This step makes the ProjectManagement module visible in the frontend UI. Step 4: Test the Integration Now that everything is configured, it’s time to test. 4.1 Backend Checklist * Run the application using Visual Studio or `dotnet run` * Check if there are any build errors * Confirm that new database tables were created 4.2 Frontend Checklist * Run `npm start` or `ng serve` * Log in to the app * Navigate through the new module in the side menu * Test create/edit/delete operations Frequently Asked Questions Q: What are the prerequisites for adding a custom ABP.io module? A: You'll need .NET SDK compatible with your ABP version, Node.js/npm, Angular CLI, ABP CLI, and an existing ABP.io application in either Modular Monolith or Microservice architecture. Q: How do I integrate the module on the backend? A: Add the required NuGet packages (`Vineforce.ProjectManagement.Application`, `Vineforce.ProjectManagement.HttpApi`) and register dependencies in `AdminHttpApiHostModule.cs`. Q: What's the best approach for database integration? A: Update your `DbContext` to call `builder.ConfigureProjectManagement()` and apply migrations using `dotnet ef migrations add` and `dotnet ef database update`. Q: How do I integrate with the Angular frontend? A: Install the module via `npm i @vineforce-modules/project-management` and add it to your Angular routes in `app-routing.module.ts`. Q: What common issues should I watch for? A: Watch for version mismatches between backend and frontend packages, database migration errors, and Angular module import issues. Common Issues & Troubleshooting | Issue | Solution | | ------------------------------- | ----------------------------------------------------------- | | Build fails after adding module | Double-check all using imports and NuGet versions | | EF migration error | Make sure DbContext is updated and compiled | | Module not showing in UI | Confirm that routing is updated correctly | | Package not found | Check internet connection and package version compatibility | Final Summary You have now successfully: * Added a module to your ABP.io backend * Linked it with your database and ran migrations * Integrated the Angular module using npm * Updated routing and tested the entire module This setup allows you to build and scale your application using modular principles without repeating core logic again and again.   Conclusion Adding a custom module to your ABP.io application is not just a technical task, it is a smart way to keep your project scalable and organized. By following this step-by-step guide, you have successfully connected your backend using NuGet, updated your database context, applied migrations, and linked the frontend through npm and Angular routing. This process helps you avoid repeating code, improves maintainability, and prepares your application for future growth. Whether you are adding one module or planning to build a fully modular system, this method will save time and reduce errors.

TypeScript’s 10x Faster Leap:Latest Go Advancements
TypeScript has long been the developer’s favorite for writing robust, type-safe JavaScript. Developed and maintained by Microsoft, it continues to evolve in response to growing codebases, demand for performance, and modern tooling needs. In early 2024, Microsoft announced one of the most ambitious changes to TypeScript since its inception—a native compiler rewrite in Go. The goal? Massive performance boosts, especially for large-scale projects that have faced limitations with the current JavaScript-based compiler. Why the Rewrite? Performance Bottlenecks and Scalability As adoption of TypeScript has surged, projects like Visual Studio Code, Angular, and massive enterprise applications now span millions of lines of code. While the JavaScript-based compiler tsc is battle-tested and feature-rich, it wasn’t built with this kind of scale in mind. Key Challenges with the Original Compiler | Issue | Impact | | ----------------------- | -------------------------------------------------------- | | Slow compile times | Wasted developer hours during build | | High memory consumption | Crashes or hangs in large projects | | Limited concurrency | JavaScript’s single-threaded nature becomes a bottleneck | | CI/CD bottlenecks | Slower release cycles and build queues | | Developer experience | Delayed feedback loops, lower productivity | The limitations were not just a technical concern; they were affecting the developer experience and slowing down team velocity in fast-paced environments. <iframe width="100%" height="450" src="https://www.youtube.com/embed/pNlq-EVld70" title="A 10x Faster TypeScript" frameborder="0" allowfullscreen> </iframe> <Blockquote name="Microsoft Dev Blog"> This is the same TypeScript you know and love, just faster, more scalable, and ready for modern development at scale. </Blockquote> TypeScript Goes Native: The Go Compiler Initiative In January 2024, Microsoft introduced an experimental port of the TypeScript compiler in Go, hosted on GitHub as microsoft/typescript-go. This wasn’t just a proof of concept—Microsoft shared real benchmarks demonstrating 10x faster builds. Core Goals of the Go Compiler * 10x faster builds for large projects * Lower memory footprint to reduce crashes * Scalability across multi-core systems * Compatibility with existing tooling * Future extensibility for enterprise needs Real Benchmark Data: TypeScript vs TypeScript-Go Microsoft tested the Go-based compiler on massive codebases like Visual Studio Code (1.5M+ LOC). Here’s what they found: | Metric | JavaScript Compiler | Go Compiler | | ----------------- | ------------------- | -------------- | | Full build time | 77.8 seconds | 7.5 seconds | | Memory usage | ~4.1 GB | ~512 MB | | Concurrency | Single-threaded | Multi-threaded | | Error diagnostics | Real-time | Real-time | Analysis The Go compiler not only delivered faster builds but significantly reduced the memory footprint, making it ideal for resource-constrained environments and CI/CD pipelines. Real-World Speed Gains Across Popular Codebases Microsoft tested the new Go-based TypeScript compiler across a variety of well-known open-source projects—including Visual Studio Code, Playwright, and TypeORM. The results show consistent, dramatic speed improvements in both build time and memory efficiency. Performance Comparison | Codebase | Size (LOC) | JavaScript Compiler | Go Compiler | Speedup | | ---------------------- | ---------- | ------------------- | ----------- | ------- | | VS Code | 1,505,000 | 77.8s | 7.5s | 10.4x | | Playwright | 356,000 | 11.1s | 1.1s | 10.1x | | TypeORM | 270,000 | 17.5s | 1.3s | 13.5x | | date-fns | 104,000 | 6.5s | 0.7s | 9.5x | | tRPC (server + client) | 18,000 | 5.5s | 0.6s | 9.1x | | rxjs (observable) | 2,100 | 1.1s | 0.1s | 11.0x | Architecture Overview: What Changed? The Go compiler isn’t a full rewrite of TypeScript—it’s a native compiler implementation that reads .ts files, parses them, builds the type graph, and emits .js files just like the original. Notable Architectural Differences * Language: Written in Go instead of JavaScript * Concurrency: Uses Go routines to handle parsing, type checking, and emitting in parallel * Performance: Optimized memory allocation, faster AST handling * Compatibility: Supports most TypeScript config options and APIs (like tsconfig.json) * Build pipeline: Rewritten with focus on CPU efficiency and cache-aware compilation Benefits for Developers Faster Feedback Loops Faster compiles lead to quicker turnaround during development, especially when using strict mode or complex generic types. Lower CI/CD Costs Faster builds = fewer compute hours. This directly benefits companies using cloud-based build agents (GitHub Actions, Azure DevOps, CircleCI). Scalable for Monorepos Monorepos are increasingly popular. The Go compiler handles many sub-projects better in parallel, thanks to its concurrency model. Simple Migration Path Drop-in compatibility allows teams to test and migrate without massive tooling changes. TypeScript Compiler Evolution  Challenges and Limitations Despite the optimism, the Go compiler is still experimental. Microsoft has been transparent about the hurdles. Current Limitations * No watch mode: Cannot yet recompile files on change * Incomplete plugin support: Plugins relying on tsserver may not work * Learning curve: Go devs may need to learn TypeScript internals, and vice versa * Ecosystem maturity: Limited community tools and support compared to tsc * Edge cases: May behave slightly differently with uncommon TS features <Blockquote name="Microsoft Engineering Team"> This is a high-risk, high-reward project. We’re learning as we go. </Blockquote> Community Reactions and Ecosystem Impact Developers on platforms like Dev.to, Reddit, Hacker News, and GitHub have been quick to weigh in. What Developers Are Saying * “Game-changing for enterprise-scale apps.” * “Go’s speed finally gets paired with TS safety.” * “Still rough, but so promising.” Open Source Momentum The GitHub project already has over 3,000 stars and dozens of contributors. It’s an active, fast-moving project with monthly updates. Key Features Comparison | Feature | JavaScript Compiler | TypeScript-Go | | -------------- | ------------------------- | -------------------- | | Build Speed | Slower in large codebases | 10x faster | | Memory Usage | High | Low | | Plugin Support | Full | Partial (WIP) | | Community | Mature ecosystem | Early adoption phase | | Language | JavaScript | Go | | Type Checking | Full | Full | | Watch Mode | Yes | Coming soon | Roadmap: What’s Coming Next? According to the GitHub Roadmap, Microsoft plans to: * Add watch mode support * Improve incremental build performance * Enhance editor services (for IDE integrations) * Reach feature parity with tsc * Expand community documentation and tooling Microsoft also encourages developer feedback and contributions to prioritize improvements based on real-world use cases. Use Cases: Where TypeScript-Go Shines Enterprise Applications Vast codebases like banking, logistics, and healthcare platforms can benefit from significantly faster build times and improved scalability. Monorepos Projects with shared libraries and multiple packages can take advantage of parallel processing and reduced compilation overhead. CI/CD Pipelines Faster builds translate directly into quicker deployments and reduced infrastructure costs. Open Source Projects Maintainers and contributors benefit from shorter feedback loops and a more responsive development experience. A Promising Future for TypeScript The move to Go marks a bold new chapter for TypeScript. While still in its early stages, the Go-based compiler delivers dramatic performance improvements, particularly for enterprise-scale projects. Microsoft’s commitment to maintaining backward compatibility means that most teams will be able to test and adopt this seamlessly. If you’re managing a large codebase, it’s worth keeping a close eye on this project—or even contributing to it. As TypeScript evolves beyond performance limits, this initiative could redefine what’s possible in typed JavaScript development. According to Microsoft.com
How Advanced Security Measures Can Safeguard Your SaaS Application

What's New in .NET 9:Faster, Safer, Smarter Features
.NET 9 brings a bunch of exciting updates that make it faster, safer, and easier to use. It improves performance, handles memory better, and makes working with collections simpler. You'll find helpful features like tools for trimming code, better ways to manage collections, and new LINQ methods. Plus, it adds safer ways to handle cryptography, makes working with time more convenient, and processes data more efficiently. Let's dive in to see how these new features make .NET 9 a great choice for developers! Key Features 1. **Feature Switches with Trimming Support** : FeatureSwitchDefinitionAttribute and FeatureGuardAttribute help reduce app size when trimming by excluding dead code based on feature flags. 2. **UnsafeAccessorAttribute for Generics**: Now supports generic parameters, enabling unsafe access to private members of generic types. 3. **Garbage Collection (DATAS)**: Dynamic Adaptation to Application Sizes automatically adjusts heap size to optimize memory usage and is enabled by default. 4. **Performance Enhancements**: Includes loop optimizations, inlining improvements, PGO enhancements, ARM64 vectorization, and faster exception handling. New Libraries 1. **Base64Url Encoding**: New Base64Url class simplifies working with URL-safe Base64 encoding. 2. **Removal of BinaryFormatter**: Removed to encourage safer serialization practices. 3. **Improved Collections**: New OrderedDictionary<TKey, TValue>, ReadOnlySet<T>, and updated PriorityQueue improve performance and flexibility. 4. **Cryptography**: New KMAC algorithm, improved key management, and OpenSSL provider support. 5. **TimeSpan Enhancements**: New integer-based overloads provide more precise time span creation and avoid floating-point precision issues. 6. **LINQ Enhancements**: New CountBy, AggregateBy, and Index methods streamline collection operations and improve efficiency. 1. Attribute Model for Feature Switches with Trimming Support The Attribute model for feature switches with trimming support in .NET allows you to define feature switches that can enable or disable functionality, helping reduce app size when trimming or compiling with Native AOT (Ahead-of-Time compilation). Key Attributes 1. **FeatureSwitchDefinitionAttribute**: Used to treat a feature-switch property as a constant during trimming, allowing dead code guarded by the switch to be removed. For example, if a feature is disabled in the project settings, related code will be removed: ```csharp if (Feature.IsSupported) Feature.Implementation(); ``` 2. **FeatureGuardAttribute**: Used for guarding code that requires attributes like RequiresUnreferencedCode, RequiresAssemblyFiles, or RequiresDynamicCode. This ensures that feature-related code is properly handled when trimming: ```csharp [FeatureGuard(typeof(RequiresDynamicCodeAttribute))] internal static bool IsSupported => RuntimeFeature.IsDynamicCodeSupported; ``` Example If the feature Feature.IsSupported is set to false in the project file, the corresponding implementation is removed when trimming, optimizing the app size: ```xml <ItemGroup> <RuntimeHostConfigurationOption Include="Feature.IsSupported" Value="false" Trim="true" /> </ItemGroup> ``` 2. UnsafeAccessorAttribute Supports Generic Parameters The UnsafeAccessorAttribute in .NET allows unsafe access to private members (fields or methods) of a class. Initially introduced in .NET 8, this feature lacked support for generic parameters. .NET 9 adds support for generic parameters in both CoreCLR and Native AOT scenarios, enabling more flexibility in accessing generic type members. Example In the following code, the UnsafeAccessorAttribute is used to access private fields and methods of a generic class: ```csharp public class Class<T> { private T? _field; private void M<U>(T t, U u) { } } class Accessors<V> { [UnsafeAccessor(UnsafeAccessorKind.Field, Name = "_field")] public extern static ref V GetSetPrivateField(Class<V> c); [UnsafeAccessor(UnsafeAccessorKind.Method, Name = "M")] public extern static void CallM<W>(Class<V> c, V v, W w); } internal class UnsafeAccessorExample { public void AccessGenericType(Class<int> c) { ref int f = ref Accessors<int>.GetSetPrivateField(c); Accessors<int>.CallM<string>(c, 1, string.Empty); } } ``` In this example, GetSetPrivateField and CallM are used to access and modify private members in a Class<int> object, with support for generic type parameters. 3. Garbage Collection Dynamic Adaptation to Application Sizes (DATAS) is a feature in .NET that automatically adjusts the application's heap size based on its memory requirements, ensuring that the heap size is roughly proportional to the long-lived data size. This improves memory efficiency by preventing excessive heap growth while maintaining performance. DATAS was introduced as an opt-in feature in .NET 8 and has been enhanced in .NET 9, enabling automatic heap size management by default. Example In .NET 9, DATAS is enabled by default, meaning applications will dynamically adjust memory usage based on the amount of long-lived data they manage. This results in more efficient memory usage without requiring manual tuning by developers. For more details, you can refer to the Dynamic Adaptation to Application Sizes (DATAS) documentation. 4. Performance Improvement The following performance improvements have been made for .NET 9: - Loop optimizations - Inlining improvements - PGO improvements: Type checks and casts - Arm64 vectorization in .NET libraries - Arm64 code generation - Faster exceptions - Code layout - Reduced address exposure - AVX10v1 support - Hardware intrinsic code generation - Constant folding for floating point and SIMD operations - Arm64 SVE support - Object stack allocation for boxes What's New in .NET 9 Libraries 1. Base64Url Base64 is an encoding scheme that converts binary data into a text format, using a set of 64 characters. This encoding is commonly used for transferring data, as it's supported by many methods like Convert.ToBase64String. However, Base64 includes characters like '+' and '/', which can conflict with URL encoding because they have special meanings in URLs. To address this issue, the Base64Url scheme was created, which uses an alternate set of characters that are URL-safe. In .NET 9, a new Base64Url class was introduced, making it easier to work with Base64Url encoding and decoding. **Example Code:** ```csharp ReadOnlySpan<byte> bytes = ...; string encoded = Base64Url.EncodeToString(bytes); ``` This example shows how to use the Base64Url.EncodeToString method to encode a byte array into a Base64Url string, suitable for use in URLs. 2. BinaryFormatter In .NET 9, the BinaryFormatter has been removed from the runtime. Although the API still exists, its implementation now always throws an exception, making it unusable. This change encourages developers to migrate to safer and more efficient serialization methods. A migration guide is available to help users transition from BinaryFormatter to alternative approaches. **Example:** If you try using BinaryFormatter in .NET 9, it will throw an exception: ```csharp var formatter = new BinaryFormatter(); formatter.Serialize(stream, obj); // This will throw an exception in .NET 9 ``` Developers are advised to use alternatives like System.Text.Json or Newtonsoft.Json for serialization tasks. 3. Collections The collection types in .NET gain the following updates for .NET 9: - Collection lookups with spans - OrderedDictionary<TKey, TValue> - PriorityQueue.Remove() method lets you update the priority of an item in the queue. - ReadOnlySet<T> Collection Lookups with Spans In high-performance scenarios, spans are used to avoid unnecessary string allocations. In .NET 9, with the new allows ref struct feature in C# 13, it's now possible to perform lookups on collection types like Dictionary<TKey, TValue> using spans. This helps optimize memory usage and performance in lookup-intensive code. **Example:** ```csharp private static Dictionary<string, int> CountWords(ReadOnlySpan<char> input) { Dictionary<string, int> wordCounts = new(StringComparer.OrdinalIgnoreCase); Dictionary<string, int>.AlternateLookup<ReadOnlySpan<char>> spanLookup = wordCounts.GetAlternateLookup<ReadOnlySpan<char>>(); foreach (Range wordRange in Regex.EnumerateSplits(input, @"\b\w+\b")) { ReadOnlySpan<char> word = input[wordRange]; spanLookup[word] = spanLookup.TryGetValue(word, out int count) ? count + 1 : 1; } return wordCounts; } ``` OrderedDictionary<TKey, TValue> The OrderedDictionary<TKey, TValue> allows both ordered storage of key-value pairs and efficient key-based lookups. In .NET 9, a generic version of OrderedDictionary is introduced, improving type safety and efficiency. **Example:** ```csharp OrderedDictionary<string, int> d = new() { ["a"] = 1, ["b"] = 2, ["c"] = 3, }; d.Add("d", 4); d.RemoveAt(0); d.RemoveAt(2); d.Insert(0, "e", 5); foreach (KeyValuePair<string, int> entry in d) { Console.WriteLine(entry); } // Output: // [e, 5] // [b, 2] // [c, 3] ``` PriorityQueue.Remove() Method .NET 6 introduced PriorityQueue<TElement, TPriority>, but it lacked efficient priority updates. The new PriorityQueue<TElement, TPriority>.Remove() method in .NET 9 allows emulating priority updates, making it suitable for algorithms like Dijkstra's algorithm in certain contexts. **Example:** ```csharp public static void UpdatePriority<TElement, TPriority>( this PriorityQueue<TElement, TPriority> queue, TElement element, TPriority priority ) { queue.Remove(element, out _, out _); // Remove the element queue.Enqueue(element, priority); // Re-enqueue with new priority } ``` ReadOnlySet<T> .NET 9 introduces ReadOnlySet<T>, a read-only wrapper for mutable sets (ISet<T>), complementing ReadOnlyCollection<T> and ReadOnlyDictionary<TKey, TValue> for other collections. **Example:** ```csharp private readonly HashSet<int> _set = new(); private ReadOnlySet<int>? _setWrapper; public ReadOnlySet<int> Set => _setWrapper ??= new ReadOnlySet<int>(_set); ``` 4. Cryptography The advancement of cryptography in .NET 9 strengthens data security by enhancing encryption algorithms and improving key management processes. CryptographicOperations.HashData() Method The CryptographicOperations.HashData() method in .NET 9 allows for one-shot hashing or HMAC operations using a specified HashAlgorithmName. This simplifies hashing operations, as it eliminates the need for conditional logic based on the algorithm, improving performance and reducing allocations. **Example:** ```csharp static void HashAndProcessData(HashAlgorithmName hashAlgorithmName, byte[] data) { byte[] hash = CryptographicOperations.HashData(hashAlgorithmName, data); ProcessHash(hash); } ``` KMAC Algorithm .NET 9 introduces the KMAC (KECCAK Message Authentication Code) algorithm, as specified by NIST SP-800-185. KMAC is a pseudorandom function based on KECCAK, supporting both one-shot and accumulated MAC generation. It's available on Linux (OpenSSL 3.0 or later) and Windows 11 (Build 26016 or later). **Example:** ```csharp if (Kmac128.IsSupported) { byte[] key = GetKmacKey(); byte[] input = GetInputToMac(); byte[] mac = Kmac128.HashData(key, input, outputLength: 32); } else { // Handle scenario where KMAC isn't available. } ``` X.509 Certificate Loading .NET 9 introduces the X509CertificateLoader class to replace older, less secure certificate loading methods. This class provides a more secure, one-method-one-purpose design for certificate loading, supporting two widely compatible formats. OpenSSL Providers Support .NET 9 enhances support for OpenSSL providers, including the ability to use SafeEvpPKeyHandle.OpenKeyFromProvider for interacting with providers such as TPM2 or PKCS11. This allows for secure key management with hardware security modules (HSM). **Example:** ```csharp byte[] data = [ /* example data */ ]; // Using a TPM provider using (SafeEvpPKeyHandle priKeyHandle = SafeEvpPKeyHandle.OpenKeyFromProvider("tpm2", "handle:0x81000007")) using (ECDsa ecdsaPri = new ECDsaOpenSsl(priKeyHandle)) { byte[] signature = ecdsaPri.SignData(data, HashAlgorithmName.SHA256); // Use signature created by TPM. } ``` This method improves performance during the TLS handshake and interaction with RSA private keys using ENGINE components. 5. TimeSpan Class Enhancements in .NET 9 The TimeSpan class in .NET 9 introduces new overloads for creating TimeSpan objects from integers. This is particularly useful to avoid precision issues that can arise when using double values, as the floating-point format can lead to slight inaccuracies. For example, TimeSpan.FromSeconds(101.832)` might result in a time span that isn't exactly 101 seconds and 832 milliseconds but instead a slightly imprecise value. The new overloads allow you to directly specify days, hours, minutes, seconds, milliseconds, and microseconds using integer values, providing a more accurate and efficient way to create TimeSpan objects. **Example:** ```csharp TimeSpan timeSpan1 = TimeSpan.FromSeconds(value: 101.832); Console.WriteLine($"timeSpan1 = {timeSpan1}"); // Output: timeSpan1 = 00:01:41.8319999 TimeSpan timeSpan2 = TimeSpan.FromSeconds(seconds: 101, milliseconds: 832); Console.WriteLine($"timeSpan2 = {timeSpan2}"); // Output: timeSpan2 = 00:01:41.8320000 ``` In this example, timeSpan1 shows the floating-point imprecision, whereas timeSpan2 demonstrates the new integer-based overload, providing a precise value. 6. LINQ LINQ (Language Integrated Query) has received enhancements in .NET 9, making querying collections even easier and more powerful, particularly with the introduction of new query operators and better async LINQ support. .NET 9 introduces new methods CountBy, AggregateBy, and Index to streamline collection operations and avoid unnecessary intermediate groupings, offering more efficient ways to process data. **1. CountBy:** This method allows you to quickly calculate the frequency of each key in a collection, similar to GroupBy, but without allocating intermediate groupings. **Example: Find the most frequent word in a text:** ```csharp string sourceText = """ Lorem ipsum dolor sit amet, consectetur adipiscing elit. Sed non risus. Suspendisse lectus tortor, dignissim sit amet, adipiscing nec, ultricies sed, dolor. Cras elementum ultrices amet diam. """; KeyValuePair<string, int> mostFrequentWord = sourceText .Split(new char[] { ' ', '.', ',' }, StringSplitOptions.RemoveEmptyEntries) .Select(word => word.ToLowerInvariant()) .CountBy(word => word) .MaxBy(pair => pair.Value); Console.WriteLine(mostFrequentWord.Key); // Output: amet ``` **AggregateBy:** This method lets you perform custom aggregation by key, replacing the need for GroupBy when you need to aggregate values in a more general-purpose manner. **Example: Aggregate scores by ID:** ```csharp (string id, int score)[] data = [ ("0", 42), ("1", 5), ("2", 4), ("1", 10), ("0", 25), ]; var aggregatedData = data.AggregateBy( keySelector: entry => entry.id, seed: 0, (totalScore, curr) => totalScore + curr.score ); foreach (var item in aggregatedData) { Console.WriteLine(item); } // Output: // (0, 67) // (1, 15) // (2, 4) ``` **Index:** This method provides a quick way to obtain the index of each item in a collection. It simplifies the process of iterating through elements with their indices. **Example: Iterate through lines in a file with their line numbers:** ```csharp IEnumerable<string> lines2 = File.ReadAllLines("output.txt"); foreach ((int index, string line) in lines2.Index()) { Console.WriteLine($"Line number: {index + 1}, Line: {line}"); } ``` These methods enhance data manipulation efficiency and readability in common workflows like counting occurrences, aggregation, and indexing.
Angular 19:New Features to Know
With each release of Angular there are enhancements in the performance and developer experience. Let us see what all new features and enhancements made in Angular 19. Incremental Hydration Incremental hydration is a performance optimization technique for Angular applications that enables selective hydration of content as needed, rather than hydrating the entire application upfront. This approach results in smaller initial bundles, improving load times and reducing layout shifts, thereby enhancing the user experience. In traditional hydration, all content is hydrated at once, which can lead to longer load times and higher First Input Delay (FID). With incremental hydration, only specific sections of the app are hydrated when required, reducing the initial load and making the app feel more responsive. For example, content above the fold can now be hydrated without causing layout shifts, which was a challenge in previous versions of Angular. Key Features 1. **Triggers for Hydration** — Hydration can be triggered using several conditions like idle state, viewport visibility, user interaction, or after a specified duration. These triggers allow you to control when deferred content should be hydrated. Example: Use @defer (hydrate on idle) to load a large component when the browser is idle, avoiding delays during critical loading stages. 2. **Customizable Hydration** — Triggers like hydrate on interaction, hydrate on hover, and hydrate on timer give developers fine-grained control over when content is hydrated. Example: Use @defer (hydrate on interaction) to defer the hydration of a component until the user interacts with it. 3. **Handling Nested @defer Blocks** — Incremental hydration supports complex scenarios like nested @defer blocks, allowing for progressive hydration as needed. 4. **Hydrate never** — This option keeps content in a deferred state indefinitely, ideal for static or rarely changing sections of the application. Example Code ```typescript @defer (hydrate on idle) { <large-cmp /> } @placeholder { <div>Large component placeholder</div> } @defer (hydrate on viewport) { <large-cmp /> } @placeholder { <div>Large component placeholder</div> } ``` Route-Level Render Mode In Angular v19, a new feature called Route-Level Render Mode allows developers to specify how each route should be rendered: server-side, client-side, or prerendered. This configuration gives developers fine-grained control over how different routes are handled during the server-side rendering (SSR) process, improving performance and flexibility. - **Server-Side Rendering (SSR):** Routes that require server-side rendering are explicitly marked with RenderMode.Server. - **Client-Side Rendering:** Routes that should be rendered only on the client side are marked with RenderMode.Client. - **Prerendering:** Routes that do not require dynamic content can be prerendered at build time, improving load times and reducing server load. The new ServerRoute interface allows you to specify the render mode for each route, and it works seamlessly with your existing route declarations. It also supports dynamic parameter resolution for prerendered routes. Example Code ```typescript export const serverRouteConfig: ServerRoute[] = [ { path: '/login', mode: RenderMode.Server }, // Render login on the server { path: '/dashboard', mode: RenderMode.Client }, // Render dashboard on the client { path: '/**', mode: RenderMode.Prerender }, // Prerender all other routes ]; // Prerendering dynamic routes with parameters export const routeConfig: ServerRoute = [{ path: '/product/:id', mode: RenderMode.Prerender, async getPrerenderPaths() { const dataService = inject(ProductService); const ids = await dataService.getIds(); // ["1", "2", "3"] return ids.map(id => ({ id })); // Dynamic prerender paths based on product IDs }, }]; ``` Resource API In Angular v19, the framework introduces the resource() API as an experimental feature to integrate asynchronous operations into Angular's signals system. While signals have traditionally focused on synchronous data (like state management and computed values), the resource() API enables signals to handle asynchronous data dependencies, making it easier to manage and track the state of data that changes over time. A resource in Angular consists of three parts: - **Request Function:** Defines the dependency (e.g., a user ID) that will trigger the asynchronous operation. - **Loader:** Executes the asynchronous operation (e.g., fetching data) when the request changes. - **Resource Instance:** Exposes signals that track both the data (once fetched) and the current status (loading, resolved, errored). The resource can be used in Angular components to handle dynamic, asynchronous data dependencies with built-in support for tracking loading and error states. Example Code ```typescript @Component(...) export class UserProfile { userId = input<number>(); // Input for the user ID userService = inject(UserService); // Injecting the user service // Defining the resource with an async loader user = resource({ request: this.userId, // Request depends on the user ID // Fetching user data loader: async ({ request: id }) => await userService.getUser(id), }); } ``` Linked Signals In Angular v19, a new primitive called linkedSignal is introduced to handle common UI patterns where mutable state needs to track changes in higher-level state. A typical use case is when you have a current selection in a UI that changes based on user input, but should reset when a list of available options changes. The linkedSignal provides a clean, declarative way to express this relationship without resorting to effects or manual state management. A linkedSignal is a writable signal that depends on another signal and updates automatically when that signal's value changes. It captures the dependency and allows for mutable state that resets based on changes in related data. Example Code ```typescript const options = signal(['apple', 'banana', 'fig']); // List of options // Choice defaults to the first option but can be changed const choice = linkedSignal(() => options()[0]); console.log(choice()); // apple // Changing the choice manually choice.set('fig'); console.log(choice()); // fig // When options change, choice resets to the new default value options.set(['peach', 'kiwi']); console.log(choice()); // peach ``` Standalone Defaults In Angular v19, the standalone components feature, introduced in Angular v14, continues to evolve. As part of this update, Angular now defaults to standalone: true for components, directives, and pipes, making it the default behavior for new components. This change ensures that standalone components, which don't require modules to function, become the primary way to structure Angular applications. Additionally, Angular v19 provides a schematic that helps developers automatically update their codebase during an ng update. This schematic removes the standalone metadata property for all standalone components, directives, and pipes, and sets standalone to false for non-standalone components. To further enforce this shift to modern APIs, Angular introduces the strictStandalone compiler flag. When enabled, this flag will throw an error if any component, directive, or pipe isn't standalone, encouraging developers to adopt standalone components and follow best practices. Zoneless Angular In Angular v19, zoneless rendering is further developed and integrated to reduce Angular's dependency on zone.js, a library historically critical for server-side rendering (SSR). Zone.js has been used to notify Angular when the rendering is complete, allowing the server to send the final page to the client. However, Angular v19 introduces a more efficient way to manage this process by eliminating the need for zone.js while still ensuring that server-side rendering waits until the app is fully ready. To address scenarios where pending HTTP requests and navigation delays the rendering, Angular provides primitives in the Angular HttpClient and Router to delay the page send-off until the app is stable. Additionally, a new RxJS operator called pendingUntilEvent is introduced, allowing developers to notify the server when Angular is still rendering, thus preventing premature page delivery. Example: Using pendingUntilEvent in SSR Here's how you can use the pendingUntilEvent operator to notify the server that Angular is still rendering and shouldn't send the page to the client until it's fully stable: ```typescript import { catchError } from 'rxjs/operators'; import { EMPTY } from 'rxjs'; subscription .asObservable() .pipe( pendingUntilEvent(injector), // Waits until rendering is complete catchError(() => EMPTY) // Handles errors silently ) .subscribe(); ``` - **pendingUntilEvent:** This operator listens for the rendering to complete, delaying the page delivery until Angular is done. - **catchError:** Handles any errors during the subscription and ensures the process continues smoothly. This mechanism ensures that server-side rendering waits for the app to fully initialize before sending the page to the user, improving performance and preventing issues caused by premature markup delivery. Angular Material and CDK in v19 Angular v19 introduces significant enhancements to Angular Material and the Component Dev Kit (CDK), improving both theming and drag-and-drop functionality. - **Enhanced Theming API:** Angular Material 3's theming system is made easier to use. The new mat.theme mixin simplifies the creation of custom themes, reducing code duplication when applying themes to individual components. - **Component Overrides:** A new Sass API (mat.sidenav-overrides) is introduced to allow component-specific style customizations, such as overriding individual design tokens (e.g., background colors). - **Two-Dimensional Drag and Drop:** The Angular CDK now supports two-dimensional drag and drop, enabling mixed orientations for draggable items (vertical and horizontal). - **Tab Reordering:** Angular CDK adds support for tab reordering, making it easy to implement draggable tabs, a feature already adopted by Google Cloud Console's BigQuery. - **New Time Picker Component:** A highly requested time picker component has been added to Angular Material, following accessibility standards and community feedback. These updates enhance developer experience, customization, and usability in Angular apps, particularly around UI components. Example: Simplified Theming with mat.theme ```scss @use '@angular/material' as mat; html { @include mat.theme(( color: ( primary: mat.$violet-palette, tertiary: mat.$orange-palette, theme-type: light ), typography: Roboto, density: 0 )); } ``` `mat.theme` is used to define a custom theme with primary and tertiary colors, typography, and density in a single, simplified mixin, reducing the need for repetitive code. Example: Two-Dimensional Drag-and-Drop with Mixed Orientation ```html <div cdkDropList cdkDropListOrientation="mixed"> @for (item of mixedTodo; track item) { <div cdkDrag> {{item}} <mat-icon cdkDragHandle svgIcon="dnd-move"></mat-icon> </div> } </div> ``` `cdkDropListOrientation="mixed"` allows the drag-and-drop list to support both vertical and horizontal orientations, providing flexibility for UI design. Instant Edit/Refresh with Hot Module Replacement (HMR) Angular v19 introduces Hot Module Replacement (HMR) for styles by default, and experimental support for template HMR behind a flag. Previously, when you made changes to a component's template or style, Angular CLI would rebuild the app and trigger a full page refresh, which could disrupt the developer flow. With HMR, changes to styles or templates are applied instantly, without refreshing the entire page or losing the application state, resulting in a faster and smoother development experience. - Style HMR is enabled by default in Angular v19, allowing you to see style changes in real-time without a page refresh. - Template HMR is experimental and can be enabled by setting a flag. Example: Enabling Template HMR To enable template HMR in Angular v19, use the following command: ```bash NG_HMR_TEMPLATES=1 ng serve ``` This will enable live updates for both styles and templates, allowing you to modify and see changes immediately without refreshing the page. Key Points - **HMR for Styles:** Enabled by default in Angular v19 for faster development. - **Template HMR:** Experimental feature that can be enabled using the NG_HMR_TEMPLATES=1 flag. - **Instant Updates:** Changes to styles and templates are reflected immediately without a page refresh, preserving the app's state. Conclusion With exciting new features like Route-Level Render Mode and Incremental Hydration, Angular 19 makes apps faster and more effective. These improvements increase user experiences, decrease server strain, and speed up load times. Now that developers have more control over the rendering of routes and content, Angular is an even better framework for creating scalable and contemporary online apps. This is the ideal moment to discover Angular 19's strong characteristics if you haven't before!
