Create a pool of a specified concurrency that accepts functions that return promises

Usage

Complete API Documentation.

To use, just make a promise pool with the specified concurrency, then wrap the method in a pool.open(() => /* the code that you want pooled */). The callback is necessary, as otherwise the code that you want pooled will execute before it is pooled. By pooling it, it executes once the pool entry is called.

import PromisePool from 'native-promise-pool'
const pool = new PromisePool(2) // 5 tasks at once
await Promise.all([
    pool.open(() => /* the thing that takes a while */)
    pool.open(() => /* the thing that takes a while */)
    pool.open(() => /* the thing that takes a while, will run after the first two have completed */)
])

Finally

This package depends on Promise.prototype.finally existing, which it does on Node v10 and above.

On older environments, you must use a shim, like so:

require('promise.prototype.finally').shim()
const pool = require('native-promise-pool').create({ concurrency: 2 })
