Create a pool of a specified concurrency that accepts functions that return promises
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.
const pool = 2 // 5 tasks at onceawait Promiseallpoolpoolpool
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:
const pool =
npm install --save native-promise-pool
import pkg from ('native-promise-pool')
const pkg = require('native-promise-pool').default
