async-step

A basic ES6 async/await chain function

This basic function allows chaining multiple promises/async functions. Two possible styles are supported. Note: Each callback will be called with the next input parameter, and the last result.

1. Single callback - Use this if every item has the same callback

const results = await asyncStep([0, 1, 2], cb);
// results will contain the output of each cb() execution
console.log(results);

2. Many callbacks - Use this if you need configurable callbacks per function

const results2 = await forEach([
 () => cb(0),
 last => cb(1, last),
 last => cb(2, last),
]);
