Node Dependency Injection

• API
  • Injector
    • class([store])
    • injector.setStore(store)
    • injector.getStore()
    • injector.resolve(func, [thisArg, staticArgs])
  • Store
    • class([dep, asyncDep])
    • store.set(name, value):
    • store.get(name)
    • store.has(name)
    • store.declare(name):
    • store.resolve(name, value)
    • store.list()
    • store.asyncList()
  • Helper
    • class.arguments([func])
    • class.functions(obj)
    • class.mapFunctions(obj)

Installation

npm i -S node-dinjector

Including library in your project

const DInjector = require('node-dinjector');
const DInjectorStore = DInjector.Store;
const DInjectorHelper = DInjector.Helper;

Example

const DInjector = require('../DInjector');
const DInjectorStore = DInjector.Store;
const DInjectorHelper = DInjector.Helper;

const injector = new DInjector();
injector.getStore().set('a', 123); // set di

class Controller {
  test(a, b) {
    console.log(a, b);
  },
  test(c, a, b) {
    console.log(c, a, b);
  }
}
const c = new Controller();
// replace c functions with resolved functions using injector
DInjectorHelper.mapFunctions(c, func => injector.resolve(func, c));
// call test function with b parameter
c.test(5);
// call test2 function with c and b parameters
c.test2(1, 2);
