What is Angular Ivy?

Angular Ivy is the new rendering engine introduced in Angular version 9. It replaces the previous View Engine and brings several improvements and benefits to the Angular framework. Here are some key points to know about Angular Ivy:

  1. Improved Bundle Size: Ivy enables better tree shaking and generates smaller bundle sizes compared to the previous View Engine. This helps in reducing application load times and improving performance, especially for larger applications.

  2. Faster Compilation: Ivy brings faster compilation times, making the development workflow more efficient. The incremental compilation feature allows for faster rebuilds when making changes to your codebase.

  3. Enhanced Debugging and Error Messages: Ivy provides improved debugging capabilities with more accurate error messages and better stack traces. This makes it easier to locate and fix issues during development.

  4. Smoother Developer Experience: Ivy introduces a more intuitive and simplified syntax for Angular templates, making it easier to understand and work with template code. It also enables better type checking and autocompletion in template files.

  5. Improved Build Time: Ivy speeds up the build process by reducing the time required for compilation. This is particularly beneficial for larger projects with a significant number of components and templates.

  6. Better Performance: Ivy includes various optimizations that improve runtime performance, such as faster rendering, optimized change detection, and improved memory management.

  7. Angular Compatibility: Angular Ivy is designed to maintain compatibility with existing Angular applications and libraries. Most existing applications can migrate to Ivy without requiring significant changes to the codebase.

  8. Incremental Adoption: Ivy allows for incremental adoption, meaning you can enable Ivy in specific parts of your application while keeping the rest of the codebase using the View Engine. This flexibility allows for a smoother migration process, especially for large applications.

It's important to note that Ivy is the default rendering engine in Angular starting from version 9. However, if you have an older Angular project, you may need to manually enable Ivy by following the migration guides provided by the Angular team.

Overall, Angular Ivy brings significant improvements in terms of performance, bundle size, and developer experience. It's recommended to stay updated with the latest Angular versions and leverage the benefits offered by Ivy in your Angular projects.
