JSPM – do@0.7.0

Package Exports

do
do/do.js

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (do) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

"do" is the simplest way to manage asynchronicity

If you don't want to use all the async/chain libraries but just want a reliable way to know when the function is done - this is for you.

Installation

npm i do

Usage

Series async execution

const chain = require('do');

const c1 = chain
  .do(readConfig, 'myConfig')
  .do(selectFromDb, 'select * from cities')
  .do(getHttpPage, 'http://kpi.ua')
  .do(readFile, 'README.md');

c1((err, result) => {
  console.log('done');
  if (err) console.log(err);
  else console.dir({ result });
});

Data collector

const chain = require('do');
const fs = require('fs');

const dc = chain.do(6);

dc('user', null, { name: 'Marcus Aurelius' });
fs.readFile('HISTORY.md', (err, data) => dc.collect('history', err, data));
fs.readFile('README.md', dc.callback('readme'));
fs.readFile('README.md', dc('readme'));
dc.take('readme', fs.readFile, 'README.md');
setTimeout(() => dc.pick('timer', { date: new Date() }), 1000);
