The Angular Ivy compiler is a significant improvement over the previous compiler, providing faster builds, better tree-shaking, and more efficient change detection. In this section, we'll explore the key features and benefits of the Ivy compiler in Angular 14.

Features of Angular Ivy Compiler

  • Faster Builds: The Ivy compiler reduces the time taken to compile Angular applications, leading to faster development cycles.
  • Improved Tree-Shaking: It eliminates unused code from the final bundle, resulting in smaller application sizes.
  • Enhanced Change Detection: The Ivy compiler uses a more efficient change detection algorithm, which reduces the number of checks needed to determine if a change has occurred.

Getting Started with Angular Ivy Compiler

To use the Ivy compiler in Angular 14, follow these steps:

  1. Update Angular: Ensure you are using Angular 14 or higher.
  2. Enable Ivy: In your angular.json file, set the Ivy option to true under the compilerOptions section.
"compilerOptions": {
  " Ivy": true
}
  1. Run Angular CLI Commands: Use the Angular CLI commands to build and serve your application with the Ivy compiler.
ng build --prod
ng serve

Performance Improvements

The Ivy compiler offers several performance improvements over the previous compiler:

  • Reduced Build Time: The Ivy compiler significantly reduces the time taken to build Angular applications, which can be particularly noticeable in large applications.
  • Smaller Application Sizes: By eliminating unused code, the Ivy compiler helps reduce the size of the final application bundle.
  • Faster Change Detection: The Ivy compiler uses a more efficient change detection algorithm, which reduces the number of checks needed to determine if a change has occurred.
