ember-cli-once

Ember CLI one-time calculation addon.

ember-cli-once exposes a factory which limits a function's executions. Its return value will be calculated on first execution and cached. Subsequent calls will immediately return the cached result.

Example

import Ember from 'ember';
import once from 'once';
 
var i = 0;
var foo = Ember.Object.create({
    increment: once(function () {
        // only ever hit once
        return ++i;
    })
});
 
foo.increment(); // -> 1
foo.increment(); // -> 1

Installing

With npm:

$ npm install --save ember-cli-once

Or with Ember CLI:

$ ember install ember-cli-once
