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

```js

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

```js

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);

```

## Run tests

`npm test`
