poolifier - npm Package Versions

[2.0.0] - 2021-03-01

Bug fixes

• Now a thread/process by default is not deleted when the task submitted take more time than maxInactiveTime configured (issue #70).

Breaking Changes

• FullPool event is now renamed to busy.

• maxInactiveTime on ThreadWorker default behavior is now changed, if you want to keep the old behavior set killBehavior to KillBehaviors.HARD. Find more details on our JSDoc.

• maxTasks option on FixedThreadPool and DynamicThreadPool is now removed since is no more needed.

• We changed some internal structures, but you shouldn't be too affected by them as these are internal changes.

Pool options types declaration merge

FixedThreadPoolOptions and DynamicThreadPoolOptions type declarations have been merged to PoolOptions<Worker>.

New export strategy

// Before
const DynamicThreadPool = require('poolifier/lib/dynamic')
// After
const { DynamicThreadPool } = require('poolifier/lib/dynamic')

But you should always prefer just using

const { DynamicThreadPool } = require('poolifier')

New type definitions for input data and response

For cluster worker and worker-thread pools, you can now only send and receive structured-cloneable data.
This is not a limitation by poolifier but Node.js.

numWorkers property is now numberOfWorkers
