debounce-hashed

Debounce based on a hashing function

This is basically underscore's debounce with an additional hashing function.

Example:

function ping(user) {
  user.ping()
}

// You want to debounce these pings at a 100ms interval,
// but on a per user basis

var debounceHashed = require('debounce-hashed')

var pingDebounced = debounceHashed(ping, function hashingFn(user) {
  return user.id
}, 100)

// Or if you ping only by userid

var pingDebounced2 = debounceHashed(function pingById(userid) {
  user.getById(userid, function (err, user) {
    if (!err && user) user.ping();
  })
}, function hashingFn(userid) {
  return userid
}, 100)

debounceHashed(fn, hashingfn, wait, [immediate])

• fn - the function to be debounced
• hashingFn - hashing function. Receives the same arguments as fn. Should return a string.
• wait
• immediate
