# p-all [](https://travis-ci.org/sindresorhus/p-all) > Run promise-returning & async functions concurrently with optional limited concurrency Similar to `Promise.all()`, but accepts functions instead of promises directly so you can limit the concurrency. If you're doing the same work in each function, use [`p-map`](https://github.com/sindresorhus/p-map) instead. See [`p-series`](https://github.com/sindresorhus/p-series) for a serial counterpart. ## Install ``` $ npm install p-all ``` ## Usage ```js const pAll = require('p-all'); const got = require('got'); (async () => { const actions = [ () => got('https://sindresorhus.com'), () => got('https://ava.li'), () => checkSomething(), () => doSomethingElse() ]; console.log(await pAll(actions, {concurrency: 2})); })(); ``` ## API ### pAll(tasks, [options]) Returns a `Promise` that is fulfilled when all promises returned from calling the functions in `tasks` are fulfilled, or rejects if any of the promises reject. The fulfilled value is an `Array` of the fulfilled values in `tasks` order. #### tasks Type: `Iterable<Function>` Iterable with promise-returning/async functions. #### options Type: `Object` ##### concurrency Type: `number`<br> Default: `Infinity`<br> Minimum: `1` Number of concurrent pending promises. ## Related - [p-map](https://github.com/sindresorhus/p-map) - Map over promises concurrently - [p-series](https://github.com/sindresorhus/p-series) - Run promise-returning & async functions in series - [p-props](https://github.com/sindresorhus/p-props) - Like `Promise.all()` but for `Map` and `Object` - [p-queue](https://github.com/sindresorhus/p-queue) - Promise queue with concurrency control - [p-limit](https://github.com/sindresorhus/p-limit) - Run multiple promise-returning & async functions with limited concurrency - [More…](https://github.com/sindresorhus/promise-fun) ## License MIT © [Sindre Sorhus](https://sindresorhus.com)
