@Injectable to @Service migration

This schematic converts eligible @Injectable classes to the @Service decorator.

How to run this migration?

The migration can be run using the following command:

ng generate @angular/core:service

By default, the migration will go over the entire application. If you want to apply this migration to a subset of the files, you can pass the path argument as shown below:

ng generate @angular/core:service --path src/app/sub-component

Example

// Before
import {Injectable} from '@angular/core';

@Injectable({providedIn: 'root'})
export class MyService {}

// After
import {Service} from '@angular/core';

@Service()
export class MyService {}

Limitations

To avoid introducing breakages into your app, the schematic will skip the following classes:

• Using constructor-based dependency injection.
• Passing any options into @Injectable aside from providedIn.
• Passing anything aside from root into providedIn.
