seng-disposable-manager

Utility class for cleaning up various destructible things like timeouts, disposable items and whatever you want to add.

Installation

yarn / npm

yarn add seng-disposable-manager

npm i -S seng-disposable-manager

Usage

Constructing and adding disposable items.

  // Construct
  const instance = new DisposableManager();

  // Disposable item
  const fooBar = {
    dispose: () => {}
  };
  
  // Add disposable item
  instance.add(fooBar);
  
  // Add interval
  instance.add(
    setInterval(() => {
      foo();
    }, 500),
    DisposableTypes.INTERVAL,
  );
  
  // Or Add interval via addInterval method
  instance.addInterval(
    setInterval(() => {
      foo();
    }, 500)
  );

Plugin/Register your own disposable types

in the callback you will get the item that you have added via the 'add' method which you can destroy/cleanup.

  DisposableManager.register('destruct', ((instance) => {
    instance.destruct();
  ));

Usage of custom/registered types

  const foo = {
    destruct: () => {}
  }
  
  disposableManagerInstance.add(foo, 'destruct');

Disposing DisposableManager

This will clean up all the added instances, timeouts and custom added items/types.

  disposableManagerInstance.dispose();

Building

In order to build seng-disposable-manager, ensure that you have Git and [Node.js] (http://nodejs .org/) installed.

Clone a copy of the repo:

git clone https://github.com/riccomediamonks/seng-disposable-manager.git

Change to the seng-disposable-manager directory:

cd seng-disposable-manager

Install dev dependencies:

yarn

Use one of the following main scripts:

yarn build           # build this project
yarn dev             # run dev-watch mode, serving example/index.html in the browser
yarn generate        # generate all artifacts (compiles ts, webpack, docs and coverage)
yarn test:unit       # run the unit tests
yarn validate        # runs validation scripts, including test, lint and coverage check
yarn lint            # run tslint on this project
yarn doc             # generate typedoc documentation

When installing this module, it adds a pre-push hook, that runs the validate script before committing, so you can be sure that everything checks out.
