Stream To Async Iterator  

Overview

stream-to-async-iterator provides a wrapper that implements Symbol.asyncIterator. This will allow streams to be usable
as async iterables that can be used in for-await-of loops.

Supports node.js 4 and up.

Installation

``
$ npm install stream-to-async-iterator
`

The examples provides use async/await syntax for for-of loops. This assumes you are in an environment that natively
supports this new syntax, or that you use a tool such as Babel. In addition, for async iterators to work properly,
the Symbol.asyncIterator symbol must be defined. Core-js or babel-polyfill can both help with that.

Usage

Import the StreamToAsyncIterator class and pass the stream to its constructor. The iterator instance can be directly
used in for-of contexts.

If the stream is in object mode, each iteration will produce the next object. See the
node documentation for more
information.

`js
#!/usr/bin/env node
'use strict';
require('core-js/es7/symbol');
const fs = require('fs');
const S2A = require('stream-to-async-iterator');


(async function() {
const readStream = fs.createReadStream(__filename);
for await (const chunk of new S2A(readStream)) {
console.log(chunk);
}
})();
``
