Webpack HMR Singleton

Utility lib to help define a hot-reloadable singleton

npm version Build Status MIT Licensed

If you want something fancier, you might want to try ud. This goal of this lib is to remain very small in scope, bytes and dependencies.

Install

npm install webpack-hmr-singleton

Usage

var single = require('webpack-hmr-singleton');
 
var thing = single(module, 'thing', function() {
  return { anything: ['you', 'want'] };
});

On the first run, the function will be called and single will return the object you've specified. After every hot reload the function won't be called and you'll just get the first one back again.

This is only really useful if the value is something mutable, that you modify during the running of your program, and want it to stick around after a hot reload.
