I like async, but I don't like putting dependencies in my code so I figured out how to use just the parts I wanted.
There are a lot of other projects that do the exact same thing and a whole lot more, but this one is mine.
And I think it's pretty.
Example
var serial = require('./');
function a(next) {
setTimeout(function () {
console.log('A');
next(null, 'A');
}, 1000);
}
function b(next) {
setTimeout(function () {
console.log('B');
next(null, 'B');
}, 100);
}
function e(next) {
setTimeout(function () {
console.log('making an error');
next(new Error('fake error'));
}, 500);
}
serial([a, b], function (err, results) {
console.log(results); // => [ 'A', 'B' ]
});
serial([b, a], function (err, results) {
console.log(results); // => [ 'B', 'A' ]
});
serial([a, e, b], function (err, results) {
console.log(results); // => [ 'A' ]
console.log(err.message); // => 'fake error'
});
