SimpleAsync

Simple library to chain and run functions with asynchronous calls.

Installation

Via npm on Node:

npm install simpleasync

Usage

Reference in your program:

var async = require('simpleasync');

Define and run steps with then:

async()
    .then(function (data) {
        console.log(data);
        return data + 1;
    })
    .then(function (data) {
        console.log(data);
    })
    .run(10);

Expected output

10
11

Define and run steps with one step using a callback. Then, you can write async steps:

async()
    .then(function (data, next) {
        console.log(data);
        next(null, data + 1); // callback(err, newdata);
    })
    .then(function (data) {
        console.log(data);
    })
    .run(10);

Expected output

10
11

Use else for catch errors:

async()
    .then(function (data) {
        console.log(data);
        throw "Houston, we have a problem";
    })
    .else(function (err) {
        console.log('error:', err);
    })
    .run(10);

Expected output

10
error: Houston, we have a problem

Raise an error in an step with callback

async()
    .then(function (data, next) {
        console.log(data);
        next("Houston, we have a problem", null);
    })
    .else(function (err) {
        console.log('error:', err);
    })
    .run(10);

Expected output

10
error: Houston, we have a problem
