RrTsdi

This library is very simple implementation of Dependency Injection written in TypeScript.

Installation

Install as npm package:

npm install rr-tsdi --save

Usage (TypeScript)

const CONFIG = 'config';
const UTIL = 'util';
 
// ----------------------------
 
interface IConfig {
  login: string;
  password: string;
}
 
const config: IConfig = {
  login: 'mylogin',
  password: 'myp4$w0rd'
};
 
// ----------------------------
 
class Util {
  public static $inject = [CONFIG];
  private config: IConfig;
 
  constructor(config: IConfig) {
    this.config = config;
  }
 
  public login(): string {
    const test = this.config.login + ' ' + this.config.password;
 
    return test;
  }
}
 
// ----------------------------
 
import { Injector } from 'rr-tsdi';
 
const injector: Injector = new Injector();
 
injector.registerService(UTIL, Util);
injector.registerValue(CONFIG, config);
 
// ----------------------------
 
const util: Util = injector.get(UTIL);
 
console.log(util.login()); // 'mylogin myp4$w0rd'

Usage directly in the browser (ES5)

var injector = new RrTsdi.Injector();
 
// ----------------------------
 
var
  CONFIG = 'config',
  UTIL = 'util';
 
// ----------------------------
 
var config = {
  login: 'mylogin',
  password: 'myp4$w0rd'
};
 
injector.registerValue(CONFIG, config);
 
// ----------------------------
 
function Util(config) {
  this.config = config;
}
 
Util.$inject = [CONFIG];
 
Util.prototype.login = function () {
  var test = this.config.login + ' ' + this.config.password;
 
  return test;
}
 
injector.registerService(UTIL, Util);
 
// ----------------------------
 
var util = injector.get(UTIL);
 
document.write(util.login()); // 'mylogin myp4$w0rd'

Usage in Node

const CONFIG = 'config';
const UTIL = 'util';
 
// ----------------------------
 
const config = {
  login: 'mylogin',
  password: 'myp4$w0rd'
};
 
// ----------------------------
 
class Util {
  constructor(config) {
    this.config = config;
  }
 
  login() {
    const test = this.config.login + ' ' + this.config.password;
 
    return test;
  }
}
 
Util.$inject = [CONFIG];
 
// ----------------------------
 
const RrTsdi = require('rr-tsdi');
const Injector = RrTsdi.Injector;
const injector = new Injector();
 
injector.registerService(UTIL, Util);
injector.registerValue(CONFIG, config);
 
// ----------------------------
 
const util = injector.get(UTIL);
 
console.log(util.login()); // 'mylogin myp4$w0rd'
