angular

1. In all setup files, the target should be esnext

Example in tsconfig.json:

Replace:

{
  "compilerOptions": {
    "target": "es5",
    "lib": ["es5", "dom"],
    "types": ["cypress", "node"]
  },
  "include": ["**/*.ts"]
}

with

{
  "compilerOptions": {
    "target": "esnext",
    "lib": ["esnext", "dom"],
    "types": ["cypress", "node"]
  },
  "include": ["**/*.ts"]
}

2. Make sure that the code strictly follows all angular standards

Please find the list of alle angular standards on the following page: https://angular.dev/style-guide. It is of the utmost importance that all configuration, HTML, TypeScript, JavaScript, and everything that consists of an angular project, to follow these standards. Changes should be made accordingly. Modernize the build tooling too

3. Make sure that Angular projects are completely reactive with the usage of signals.

With the inception of signals, reactive programming for the front-end has been made easy. Make sure that, whenever possible, that the code uses signals instead of the typical subscriber model. Find information on how to do this with good practices over at: https://angular.dev/guide/signals Refactor subscribe() to resource()/rxResource()

4. Make sure to use new methods for deprecated classes

The RouterTestingModule and the HttpClientTestingModule have been deprecated. Can you make sure to replace the TypeScript declarations accordingly?

From RouterTestingModule.

Use provideRouter or RouterModule/RouterModule.forRoot instead. This module was previously used to provide a helpful collection of test fakes, most notably those for Location and LocationStrategy. These are generally not required anymore, as MockPlatformLocation is provided in TestBed by default. However, you can use them directly with provideLocationMocks.

From HttpClientTestingModule.

Add provideHttpClientTesting() to your providers instead.

Use both definitions to make the changes wherever possible.

5. Checklist

[] All targets in tsconfig.json files should be set to esnext [] No target should remain with old target compiler option versions
