Simple IoC
A simple inversion of control (IoC) library. This is a lightweight annotation-based dependency injection container for typescript.
Installation
You can install this package using NPM:
npm i @dmytropaduchak/simple-ioc --save
How use
Example with class injection:
import { Registry, registry, inject } from '@dmytropaduchak/simple-ioc';
class B {}
class A {
@inject() private readonly b: B;
}
@registry([A, B])
class App {
@inject() private readonly a: A;
@inject() private readonly registry: Registry;
}
Example with raw object injection:
import { Registry, registry, inject } from '@dmytropaduchak/simple-ioc';
const name = 'env';
const value = process.env;
@registry([{ name, value }])
class App {
@inject() private readonly env
}
Example with custom name injection:
class B {}
class A {}
@registry([A])
class App {
@inject('a') private readonly b: A;
@inject('b') private readonly a: B;
}
Example with factory injection:
import { Registry, registry, inject } from '@dmytropaduchak/simple-ioc';
interface Options {
...
}
class A {
constructor(options: Options) {
console.log(options)
}
}
const inject = A;
const useFactory = (): Options => { ... }
@registry([{ inject, useFactory }])
class App {
@inject() private readonly a
}
