If you have multiple async function calls that you want to run in parallel and collect all their results in an array, this is the module for you.
It's like after-all with a build in results aggregator.
npm install after-all-results
First require the module:
var afterAll = require('after-all-results');Then initialize with a callback that should be called once all the async stuff is done:
var next = afterAll(function (err, results) {
// all done!
console.log(results);
});The returned next function is essentially just a smart
callback-generator. The after-all-results module will wait and not call
the all-done function until all the generated callbacks have been
called:
someAsyncFunction(next());
anotherAsyncFunction(next());Note: It is important that all next() calls are done on the same
tick as the inital call to afterAll()!
var next = afterAll(function (err, results) {
// results will be an array of `arg1` from below
console.log('Done with everything!');
});
async(next(function (err, arg1, arg2) {
console.log('Done with first call to async');
});
async(next(function (err, arg1, arg2) {
console.log('Done with second call to async');
});MIT
