ts-sdi v0.0.6

Very simple di container

Just another di container

• simple api
• good ts support
• lazy initialization
• async services

install

yarn add ts-sdi

or

npm i ts-sdi

Usage

  import { Container } from 'ts-sdi'

  const container = new Container()
    // creates ones
    .bind('serviceA', () => new A()) 
    // creates on every call
    .factory('serviceB', (c) => new B(c.get('serviceA')))
    .bind('serviceC', async () => new C())
    .bind('value', () => 42)
    .bind('const', () => 101 as const);

// with chaining you will get ts support
// container: Container<{serviceA: A, serviceB: B, serviceC: Promise<C>, value: number, 'const': 101 }>

// b: B
const b = container.get('serviceB');
// c: C
const c = await container.get('serviceC');

Helper provide

provide - very simple function like (c: Container) => c.bind()... but with ts typings

  // myModule/provider.ts
  import { provide } from 'ts-sdi'

  const myModuleProvider = provide(c => 
    c.bind('service', () => new A())
     .bind('serviceB', () => new B())
  )


  // di.ts
  import pipe from 'lodash/fp';
  
  export const createContainer = () => 
    pipe(
      myModuleProvider, 
      anotherModuleProvider
    )(new Container())
