Value Objects

Step 1: Write Your Code

interface IConfig {
  apiUrl: string;
}

/**
 * @value
 */
const config: IConfig = { apiUrl: 'https://api.example.com' };

interface IUserService {
  getUser(id: string): Promise<User>;
}

/**
 * @value
 */
const userService: IUserService = {
  getUser: (id: string) => Promise.resolve({ id, name: 'User' })
};

Step 2: Generate Container

npx @notjustcoders/ioc-arise generate

Step 3: Generated Code

container.gen.d.ts:

export interface ContainerRegistry {
  'IConfig': IConfig;
  'IUserService': IUserService;
}

container.gen.ts:

import { Container } from '@notjustcoders/di-container';
import type { ContainerRegistry } from './container.gen.d';
import { config } from './config';
import { userService } from './userService';

export const container = new Container<ContainerRegistry>();

container.register('IConfig', { useValue: config });
container.register('IUserService', { useValue: userService });

Step 4: Use It

import { container } from './container.gen';

const config = container.resolve('IConfig');
const userService = container.resolve('IUserService');
//    ^? IUserService - Full type safety!
