gearman client and worker library

Gearman Client and Worker

  • full implementation of worker and client
  • lean abstraction over raw gearman protocol
  • lots of unit tests
  • fast
  • small
  • fully interoperable with gearman clients and workers written in other languages
  • lacks elegant high level abstractions for doing work. A bit more boilerplate to write
  • only supports 1 server connection per client/worker

const gearman = require('gearman')
let client = gearman("localhost", 4730 , {timeout: 3000})  // timeout in milliseconds.  
// handle timeout  
client.on('timeout', function() {
    console.log('Timeout occurred')
// handle finished jobs 
client.on('WORK_COMPLETE', function(job) {
    console.log('job completed, result:', job.payload.toString())
// connect to the gearman server 
client.connect(function() {
    // submit a job to uppercase a string with normal priority in the foreground 
    client.submitJob('upper', 'Hello, World!')
const gearman = require('gearman')
let worker = gearman('', 4730)
// handle jobs assigned by the server 
worker.on('JOB_ASSIGN', function(job) {
    console.log(job.func_name + ' job assigned to this worker')
    let result = job.payload.toString().toUpperCase()
    // notify the server the job is done 
    worker.sendWorkComplete(job.handle, result)
    // go back to sleep, telling the server we're ready for more work 
// grab a job when the server signals one is available 
worker.on('NOOP', function() {  worker.grabJob() })
// connect to the gearman server  
    // register the functions this worker is capable of 
    // tell the server the worker is going to sleep, waiting for work
