Breaking Changes

compiler-cli

• • Previously hidden type issues in host bindings may show up in your builds. Either resolve the type issues or set "typeCheckHostBindings": false in the angularCompilerOptions section of your tsconfig.

core

• The server-side bootstrapping process has been changed to eliminate the reliance on a global platform injector.

  Before:

  const bootstrap = () => bootstrapApplication(AppComponent, config);
  

  After:

  const bootstrap = (context: BootstrapContext) =>
    bootstrapApplication(AppComponent, config, context);
  

  A schematic is provided to automatically update main.server.ts files to pass the BootstrapContext to the bootstrapApplication call.

  In addition, getPlatform() and destroyPlatform() will now return null and be a no-op respectively when running in a server environment.

• • TypeScript versions less than 5.9 are no longer supported.

Similar packages

Other packages similar to @angular/compiler

babel

Babel is a JavaScript compiler that converts ECMAScript 2015+ code into a backwards-compatible version of JavaScript that can be run by older JavaScript engines. Babel is similar to @angular/compiler in that it performs code transformation, but it is not specific to Angular and does not compile Angular templates.

typescript

TypeScript is a superset of JavaScript that compiles to plain JavaScript. It is similar to @angular/compiler in that it performs a compilation step, but TypeScript focuses on type-checking and converting TypeScript code to JavaScript, rather than compiling framework-specific templates.

vue-template-compiler

The vue-template-compiler package is used to compile Vue.js templates into render functions. It is similar to @angular/compiler as both are used for compiling framework-specific templates, but they target different frameworks (Vue.js vs Angular).
