Usage

Using the promise pool is pretty straightforward. The pacakge exposes a class and you can create a promise pool instance using the fluent interface.

Here’s an example using the default concurrency of 10:

const PromisePool = require('@supercharge/promise-pool')

const users = [
  { name: 'Marcus' },
  { name: 'Norman' },
  { name: 'Christian' }
]

const { results, errors } = await PromisePool
  .for(users)
  .process(async data => {
    const user = await User.createIfNotExisting(data)

    return user
  })

You can surely refine the concurrency to your needs using the .withConcurrency method:

await PromisePool
  .for(users)
  .withConcurrency(2)
  .process(async data => {
    //
  })
