redi
redi (pronounced 'ready') is a dependency injection library for TypeScript (and JavaScript), along with a set of bindings for React.
💡
Write code that is less coupling, more convenient to modify and easier to maintain with help of dependency injection.
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)
