@csejtei/simple-container v1.0.3

Simple Dependency Injection Container

Install

npm i @csejtei/simple-container

Usage

Use container in your controllers:

• pass a container through the constructor
• get any injectable item (= dependency) (e.g.: a service) from the container
• use injected service anywhere in the controller

Imagine the following example: You have a UserController which is using your custom UserService service, you can inject userService with the Container

import { Container } from '@csejtei/simple-container';
import UserService from '../services/UserService';

class UserController {
    userService: UserService;

    constructor(container: Container) {
        this.userService = container.get(UserService);
    }

    generateUserHash(salt) {
        return this.userService.generateHash(salt);
    }
}

Your UserService has to implement Injectable:

class UserService implement Injectable {
    // generateHash ...etc
}
