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)
