3.2.0 - 2024-03-25

Added

• add "sideEffects": false to package.json #83

Updated

• updated types for the handler function in the promise pool processor

Updated

• bump dependencies

3.1.1 - 2024-01-31

Updated

• bump dependencies

Fixed

• removed duplicated build files from dist (fixing https://github.com/supercharge/promise-pool/issues/82)

3.1.0 - 2023-09-25

Added

• clear timers from task timeouts to remove them from the event loop: this is helpful to clear up resources for long-running timeouts and fastly resolving tasks. If not cleared, the timeouts stay in the event loop until they’re due
• add keep error handler when calling pool.handleError after pool.for: previously the error handler was lost

Updated

• bump dependencies

3.0.0 - 2023-07-09

Added

• Accept iterables and async iterables and not just arrays
• add performance testing script in performance directory: this is helpful to detect whether the promise pool is significantly slower than Promise.all

Updated

• bump dependencies
• call Error.captureStackTrace only when available

Breaking Changes

• require Node.js v16
• require ecmaScript 2021
• the pool.items() method changed from the narrower type T[] to the wider type T[] | Iterable<T> | AsyncIterable<T> which might be a breaking change for your code base

2.4.0 - 2023-02-10

Added

• support task timeouts
• support corresponding results

Updated

• bump dependencies
• refined types when a promise or non-promise resuult will be handled

2.3.2 - 2022-08-05

Fixed

• remove active task after handling the result or error #51
  • we previously removed the active tasks before handling the result or error, which caused the pool to pick up the next task too early

2.3.1 - 2022-08-05

Updated

• bump dependencies

Fixed

• stop processing items after throwing an error from inside the pool.handleError() method #51

2.3.0 - 2022-06-08

Added

• pool.useConcurrency(<num>): adjust the concurrency of a running pool

Updated

• bump dependencies

2.2.0 - 2022-05-20

Added

• pool.onTaskStarted((item, pool) => { … }): configure a callback that runs when an item is about to be processed
• pool.onTaskFinished((item, pool) => { … }): configure a callback that runs when an item finished processing

Updated

• bump dependencies

2.1.0 - 2021-12-14

Added

• keep the original error in error.raw
  • this is useful if your errors store some kind of context
  • the PromisePoolError instance would otherwise loose the original error context

class CustomError extends Error { … }

const { errors } = await PromisePool
  .withConcurrency(2)
  .for([1, 2, 3])
  .process(() => {
    throw new CustomError('Oh no')
  })

errors[0].raw instanceof CustomError
// true

Updated

• bump dependencies
• run tests for Node.js v17
