Breaking Changes

compiler

• this.foo property reads no longer refer to template context variables. If you intended to read the template variable, do not use this..

core

• Angular directives, components and pipes are now standalone by default.

  • Specify standalone: false for declarations that are currently declared in @NgModules.
  • ng update for v19 will take care of this automatically.

• TypeScript versions less than 5.5 are no longer supported.

• Timing changes for effect API (in developer preview):

  • effects which are triggered outside of change detection run as part of
    the change detection process instead of as a microtask. Depending on the
    specifics of application/test setup, this can result in them executing
    earlier or later (or requiring additional test steps to trigger; see below
    examples).

  • effects which are triggered during change detection (e.g. by input
    signals) run earlier, before the component's template.

• ExperimentalPendingTasks has been renamed to PendingTasks.

• The autoDetect feature of ComponentFixture will now
  attach the fixture to the ApplicationRef. As a result, errors during
  automatic change detection of the fixture be reported to the ErrorHandler.
  This change may cause custom error handlers to observe new failures that were previously unreported.

• createComponent will now render default fallback with empty projectableNodes.

  • When passing an empty array to projectableNodes in the createComponent API, the default fallback content
    of the ng-content will be rendered if present. To prevent rendering the default content, pass document.createTextNode('') as a projectableNode.

  // The first ng-content will render the default fallback content if present
  createComponent(MyComponent. { projectableNodes: [[], [secondNode]] });
  
  // To prevent projecting the default fallback content:
  createComponent(MyComponent. { projectableNodes: [[document.createTextNode('')], [secondNode]] });

• Errors that are thrown during ApplicationRef.tick
  will now be rethrown when using TestBed. These errors should be
  resolved by ensuring the test environment is set up correctly to
  complete change detection successfully. There are two alternatives to
  catch the errors:

  • Instead of waiting for automatic change detection to happen, trigger
    it synchronously and expect the error. For example, a jasmine test
    could write expect(() => TestBed.inject(ApplicationRef).tick()).toThrow()
  • TestBed will reject any outstanding ComponentFixture.whenStable promises. A jasmine test,
    for example, could write expectAsync(fixture.whenStable()).toBeRejected().

  As a last resort, you can configure errors to not be rethrown by
  setting rethrowApplicationErrors to false in TestBed.configureTestingModule.

• The timers that are used for zone coalescing and hybrid
  mode scheduling (which schedules an application state synchronization
  when changes happen outside the Angular zone) will now run in the zone
  above Angular rather than the root zone. This will mostly affect tests
  which use fakeAsync: these timers will now be visible to fakeAsync
  and can be affected by tick or flush.

• The deprecated factories property in KeyValueDiffers has been removed.

elements

• as part of switching away from custom CD behavior to the
  hybrid scheduler, timing of change detection around custom elements has
  changed subtly. These changes make elements more efficient, but can cause
  tests which encoded assumptions about how or when elements would be checked
  to require updating.

localize

• The name option in the ng add @localize`` schematic has been removed in favor of the project option.

platform-browser

• The deprecated BrowserModule.withServerTransition method has been removed. Please use the APP_ID DI token to set the application id instead.

router

• The Router.errorHandler property has been removed.
  Adding an error handler should be configured in either
  withNavigationErrorHandler with provideRouter or the errorHandler
  property in the extra options of RouterModule.forRoot. In addition,
  the error handler cannot be used to change the return value of the
  router navigation promise or prevent it from rejecting. Instead, if you
  want to prevent the promise from rejecting, use resolveNavigationPromiseOnError.
• The return type of the Resolve interface now includes
  RedirectCommand.

@coderabbitai, how to upgrade from angular 16 to 19

[coderabbitai]

Tip

For best results, initiate chat on the files or code changes.

@rajadilipkolli, upgrading from Angular 16 to 19 involves several major version updates. Here are the steps you can follow to perform the upgrade:

1. Review the Angular Update Guide:

   Since you're jumping multiple major versions, it's essential to be aware of the changes in each version. You can refer to the Angular official update guide for detailed information on changes between versions.

2. Update Dependencies Sequentially:

   It's recommended to update one major version at a time to handle deprecations and breaking changes properly.

   • Upgrade to Angular 17:

     ng update @angular/core@17 @angular/cli@17

     After updating, check your application for any issues, run tests, and fix any deprecation warnings or breaking changes.

   • Upgrade to Angular 18:

     ng update @angular/core@18 @angular/cli@18

     Again, verify your application, run tests, and address any issues.

   • Upgrade to Angular 19:

     ng update @angular/core@19 @angular/cli@19

3. Update Other Angular Packages:

   Ensure all other Angular packages are updated to the latest version:

   ng update @angular/animations @angular/common @angular/compiler @angular/compiler-cli \
     @angular/forms @angular/platform-browser @angular/platform-browser-dynamic \
     @angular/router @angular/language-service @angular/localize

4. Update Third-Party Dependencies:

   Check for updates to third-party libraries and ensure they are compatible with Angular 19.

5. Address Breaking Changes:

   • TypeScript Version: Angular 19 may require a newer version of TypeScript. Update your TypeScript dependency if needed.
   • API Changes: Review the changelogs for deprecated APIs or changes in existing APIs.
   • RxJS Version: Update RxJS to the version compatible with Angular 19.

6. Run and Test Your Application:

   • Build your application:

     ng build

   • Serve your application locally to check for runtime errors:

     ng serve

   • Run your test suites:

     ng test

7. Update Configuration Files:

   • Check tsconfig.json, .browserslistrc, and other configuration files for any required updates.
   • Update Angular Material or other Angular libraries if you're using them.

8. Refactor Code if Necessary:

   • Replace deprecated features with their recommended alternatives.
   • Update code syntax to align with the latest best practices.

9. Monitor for Issues:

   • Keep an eye on the console output for any warnings or errors.
   • Use linting tools to identify potential issues.

Note: Always ensure you have a backup of your project or use version control (like Git) to manage changes. It's also a good idea to perform these updates on a separate branch.

Let me know if you need further assistance with any specific migration steps or if you encounter issues during the upgrade process.
