async-step v1.0.1

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),
   ]);
