continue-compose (pattern deprecated -- just use async / await)

continue-compose composes continue functions, namely functions that may be passed as the onFullfilled parameter to Promise.then() to be executed serially and in an asynchronous fashion. Practically speaking, this is exactly how continue-compose will compose these functions, via Promise.then.

Basic Usage

const Composer = require('continue-compose');
const fs = require('fs');

const action1 = function(x) {
  return x * 5;
}

const action2 = function(x) {
 return Promise.resolve(x+1);
}

const action3 = function(x) {
  return fs.Promises.writeFile('out.txt', x.toString());
}

const composer = new Composer(action1, action2, action3);
const result = composer.reduce(2); // result is a promise that when resolved will have written the value 11 to out.txt
