promisegate v0.1.2
promisegate
Takes (args...) -> Promise
and turns it into (args...) -> Promise
with limited concurrency.
Useful for capping expensive async calls (e.g. image processing).
Arguments are proxied to the wrapped function.
Assumes your promise library of choice defines .resolve
, .defer
and .prototype.finally
.
var Promise = require('bluebird');
var gate = require('promisegate')(Promise) // pass promise lib of your choice
var someFunctionReturningPromise = gate.limit(function () {
// do work
}, 666);
But actually, it's about ethics in game journalism.
