1. Angular Ivy: The Evolution of the Compiler

Background:

Angular 10 fully embraces Ivy, the next-generation compilation and rendering pipeline. Ivy brings improved bundle sizes, faster compilation, and enhanced debugging capabilities.

// tsconfig.json
{
  "angularCompilerOptions": {
    "enableIvy": true
  }
}

2. Strict Mode: Enhanced Static Typing

Background:

Angular 10 introduces strict mode, providing enhanced static typing for improved maintainability and catching potential issues at compile-time.

// tsconfig.json
{
  "angularCompilerOptions": {
    "strictTemplates": true,
    "strictInjectionParameters": true
  }
}

3. TSlib 2.0: Smaller Bundle Sizes

Background:

TSlib 2.0, included with Angular 10, helps reduce bundle sizes by optimizing the runtime library.

# Install TSlib 2.0
npm install tslib@2.0.0

4. Improved Angular CLI

Background:

Angular CLI is enhanced in version 10, providing better developer experience with streamlined commands and improved performance.

# Update Angular CLI
ng update @angular/cli@10.0.0

5. Deprecation of ViewEngine

Background:

Angular 10 marks the deprecation of the ViewEngine, signaling the complete transition to Ivy as the default rendering engine.

Example:

No specific code example, but developers should be aware of the deprecation notice and migrate away from ViewEngine-specific features.

6. Breaking Changes and Updates

Background:

Angular 10 brings various breaking changes and updates to third-party dependencies, emphasizing the importance of reading the official release notes for a smooth upgrade.

Example:

Check the official Angular 10 release notes for a comprehensive list of breaking changes and updates.

7. Angular Language Service Improvements

Background:

The Angular Language Service, used for editor support and type checking, sees improvements in Angular 10, enhancing the developer experience.

Example:

No specific code example, but developers benefit from improved autocompletion and type checking in supported editors.

Conclusion

Angular 10 continues the tradition of Angular’s evolution, bringing advancements in performance, maintainability, and developer experience. By adopting features like Ivy, strict mode, and the improved Angular CLI, developers can ensure their projects stay at the forefront of modern web development.

As you embark on the journey with Angular 10, leverage these features to enhance your development workflow, optimize your applications, and stay aligned with best practices. Don’t forget to consult the official documentation and release notes for in-depth insights and guidance.

Happy coding!
