refpool

refpool

Pool of references that gc the least recently unref'ed ones when it reaches a max size

npm install refpool

Usage

const Pool = require('refpool')

const p = new Pool({
  maxSize: 42,
  close (data) {
    console.log('should close', data)
  }
})

const someResource = ...

p.add(data) // add it to the pool
p.increment(data) // add it and increment the reference count
p.decrement(data) // decrement the ref count
p.bump(data) // indicate that you used a thing in the pool

When more than maxSize items are inserted the least recently used resource with no references will be passed to close.
