p-limit
Run multiple promise-returning & async functions with limited concurrency
Works in Node.js and browsers.
Install
1npm install p-limit
Usage
1import pLimit from 'p-limit'; 2 3const limit = pLimit(1); 4 5const input = [ 6 limit(() => fetchSomething('foo')), 7 limit(() => fetchSomething('bar')), 8 limit(() => doSomething()) 9]; 10 11// Only one promise is run at once 12const result = await Promise.all(input); 13console.log(result);
API
pLimit(concurrency)
Returns a limit function.
concurrency
Type: number
Minimum: 1
Concurrency limit.
limit(fn, ...args)
Returns the promise returned by calling fn(...args).
fn
Type: Function
Promise-returning/async function.
args
Any arguments to pass through to fn.
Support for passing arguments on to the fn is provided in order to be able to avoid creating unnecessary closures. You probably don't need this optimization unless you're pushing a lot of functions.
limit.activeCount
The number of promises that are currently running.
limit.pendingCount
The number of promises that are waiting to run (i.e. their internal fn was not called yet).
limit.clearQueue()
Discard pending promises that are waiting to run.
This might be useful if you want to teardown the queue at the end of your program's lifecycle or discard any function calls referencing an intermediary state of your app.
Note: This does not cancel promises that are already running.
limit.concurrency
Get or set the concurrency limit.
FAQ
How is this different from the p-queue package?
This package is only about limiting the number of concurrent executions, while p-queue is a fully featured queue implementation with lots of different options, introspection, and ability to pause the queue.
