Dispowser

What is that ?

Dispowser is a tool which facilitate resource disposing management. Easy to use, aimed to support more and more use cases to automate disposing.

Current framework supported

• AngularJS
• RxJS

Examples

Manual disposing

  function WebsocketWrapper() {
    this.ws = new Websocket("ws://localhost:4573"); // rxjs subject
    this.ws.onclose = () => console.log("closed");

    this.dispose = () => {
      this.ws.close();
    };
  }

  let disposer = Dispowser.createDisposer();
  let disposableObject = new WebsocketWrapper();

  disposer.register = disposableObject;

  /*** [...] ***/

  disposer.dispose();
  // Console: "closed"

Manual disposing with RxJS

  let subject = new Rx.Subject();

  let disposer = Dispowser.createDisposer();
  let disposableObject = subject.subscribe((event) => console.log(event));

  disposer.register = disposableObject;

  subject.next("hello!");
  // Console : hello!

  /*** [...] ***/

  disposer.dispose();

  subject.next("hello again ?!");
  // Console : Nothing will happen

Automatic disposing with AngularJs

  function WebsocketWrapper() {
    this.ws = new Websocket("ws://localhost:4573"); // rxjs subject
    this.ws.onclose = () => console.log("closed");

    this.dispose = () => {
      this.ws.close();
    };
  }

  angular.module("module").controller("controller", ["$scope", function($scope) {
    let disposer = Dispowser.createDisposer($scope);
    let disposableObject = new WebsocketWrapper();

    disposer.register = disposableObject;
  }]);

  // If controller is destroyed
  // Console : closed
