+# p-filter [![Build Status](https://travis-ci.org/sindresorhus/p-filter.svg?branch=master)](https://travis-ci.org/sindresorhus/p-filter)
+
+> Filter promises concurrently
+
+Useful when you need to run promise-returning & async functions multiple times with different inputs concurrently and get a filtered down result.
+
+
+## Install
+
+```
+$ npm install p-filter
+```
+
+
+## Usage
+
+```js
+const pFilter = require('p-filter');
+const getWeather = require('get-weather'); // not a real module
+
+const places = [
+	getCapital('Norway').then(info => info.name),
+	'Bangkok, Thailand',
+	'Berlin, Germany',
+	'Tokyo, Japan'
+];
+
+const filterer = async place => {
+	const weather = await getWeather(place);
+	return weather.temperature > 30;
+};
+
+(async () => {
+	const result = await pFilter(places, filterer);
+
+	console.log(result);
+	//=> ['Bangkok, Thailand']
+})();
+```
+
+
+## API
+
+### pFilter(input, filterer, [options])
+
+Returns a `Promise` that is fulfilled when all promises in `input` and ones returned from `filterer` are fulfilled, or rejects if any of the promises reject. The fulfilled value is an `Array` of the fulfilled values returned from `filterer` in `input` order.
+
+#### input
+
+Type: `Iterable<Promise|any>`
+
+Iterated over concurrently in the `filterer` function.
+
+#### filterer(element, index)
+
+Type: `Function`
+
+The filterer function that decides whether an element should be included into result. Expected to return `boolean | Promise<boolean>`.
+
+#### options
+
+Type: `Object`
+
+##### concurrency
+
+Type: `number`<br>
+Default: `Infinity`<br>
+Minimum: `1`
+
+Number of concurrently pending promises returned by `filterer`.
