node_modules/async-limiter/readme.md

+# Async-Limiter
+
+A module for limiting concurrent asynchronous actions in flight. Forked from [queue](https://github.com/jessetane/queue).
+
+[![npm](http://img.shields.io/npm/v/async-limiter.svg?style=flat-square)](http://www.npmjs.org/async-limiter)
+[![tests](https://img.shields.io/travis/STRML/async-limiter.svg?style=flat-square&branch=master)](https://travis-ci.org/STRML/async-limiter)
+[![coverage](https://img.shields.io/coveralls/STRML/async-limiter.svg?style=flat-square&branch=master)](https://coveralls.io/r/STRML/async-limiter)
+
+This module exports a class `Limiter` that implements some of the `Array` API.
+Pass async functions (ones that accept a callback or return a promise) to an instance's additive array methods.
+
+## Motivation
+
+Certain functions, like `zlib`, have [undesirable behavior](https://github.com/nodejs/node/issues/8871#issuecomment-250915913) when
+run at infinite concurrency.
+
+In this case, it is actually faster, and takes far less memory, to limit concurrency.
+
+This module should do the absolute minimum work necessary to queue up functions. PRs are welcome that would
+make this module faster or lighter, but new functionality is not desired.
+
+Style should confirm to nodejs/node style.
+
+## Example
+
+``` javascript
+var Limiter = require('async-limiter')
+
+var t = new Limiter({concurrency: 2});
+var results = []
+
+// add jobs using the familiar Array API
+t.push(function (cb) {
+  results.push('two')
+  cb()
+})
+
+t.push(
+  function (cb) {
+    results.push('four')
+    cb()
+  },
+  function (cb) {
+    results.push('five')
+    cb()
+  }
+)
+
+t.unshift(function (cb) {
+  results.push('one')
+  cb()
+})
+
+t.splice(2, 0, function (cb) {
+  results.push('three')
+  cb()
+})
+
+// Jobs run automatically. If you want a callback when all are done,
+// call 'onDone()'.
+t.onDone(function () {
+  console.log('all done:', results)
+})
+```
+
+## Zlib Example
+
+```js
+const zlib = require('zlib');
+const Limiter = require('async-limiter');
+
+const message = {some: "data"};
+const payload = new Buffer(JSON.stringify(message));
+
+// Try with different concurrency values to see how this actually
+// slows significantly with higher concurrency!
+//
+// 5:        1398.607ms
+// 10:       1375.668ms
+// Infinity: 4423.300ms
+//
+const t = new Limiter({concurrency: 5});
+function deflate(payload, cb) {
+  t.push(function(done) {
+    zlib.deflate(payload, function(err, buffer) {
+      done();
+      cb(err, buffer);
+    });
+  });
+}
+
+console.time('deflate');
+for(let i = 0; i < 30000; ++i) {
+  deflate(payload, function (err, buffer) {});
+}
+t.onDone(function() {
+  console.timeEnd('deflate');
+});
+```
+
+## Install
+
+`npm install async-limiter`
+
+## Test
+
+`npm test`
+
+## API
+
+### `var t = new Limiter([opts])`
+Constructor. `opts` may contain inital values for:
+* `t.concurrency`
+
+## Instance methods
+
+### `t.onDone(fn)`
+`fn` will be called once and only once, when the queue is empty.
+
+## Instance methods mixed in from `Array`
+Mozilla has docs on how these methods work [here](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array).
+### `t.push(element1, ..., elementN)`
+### `t.unshift(element1, ..., elementN)`
+### `t.splice(index , howMany[, element1[, ...[, elementN]]])`
+
+## Properties
+### `t.concurrency`
+Max number of jobs the queue should process concurrently, defaults to `Infinity`.
+
+### `t.length`
+Jobs pending + jobs to process (readonly).
