redi

redi (pronounced ‘ready’) is a dependency injection library for TypeScript (and JavaScript), along with a set of bindings for React.

Overview

import { Inject } from "@wendellhu/redi";
 
class AuthService {
  public getCurrentUserInfo(): UserInfo {
    // your implementation here...
  }
}
 
class FileListService {
  constructor(@Inject(AuthService) private readonly authService: AuthService) {}
 
  public getUserFiles(): Promise<Files> {
    const currentUser = this.authService.getCurrentUserInfo();
    // ...
  }
}
 
const injector = new Injector([[AuthService], [FileListService]]);
injector.get(AuthService);
