Run promise-returning & async functions concurrently with optional limited concurrency

Similar toPromise.all(), but accepts functions instead of promises directly so you can limit the concurrency.

If you're doing the same work in each function, usep-map instead.

Seep-series for a serial counterpart.

npm install p-all

importpAllfrom'p-all';importgotfrom'got';constactions=[()=>got('https://sindresorhus.com'),()=>got('https://avajs.dev'),()=>checkSomething(),()=>doSomethingElse()];console.log(awaitpAll(actions,{concurrency:2}));

Returns aPromise that is fulfilled when all promises returned from calling the functions intasks are fulfilled, or rejects if any of the promises reject. The fulfilled value is anArray of the fulfilled values intasks order.

Type:Iterable<Function>

Iterable with promise-returning/async functions.

Type:object

Type:number(Integer)
Default:Infinity
Minimum:1

Number of concurrently pending promises.

Type:boolean
Default:true

When set tofalse, instead of stopping when a promise rejects, it will wait for all the promises to settle and then reject with anAggregateError containing all the errors from the rejected promises.

Type:AbortSignal

You can abort the promises usingAbortController.
