after-all-results
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.
Installation
npm install after-all-results
Usage
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) {
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()
!
Bonus: Inception mode
var next = afterAll(function (err, results) {
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');
});
