bfy-worker

not published on npm yet, pending this pull request getting merged.

(pronounced "beefy worker"), this makes creating web workers from browserify fast, fun, and easy!

var spawn = require('bfy-worker')
  , worker

worker = spawn(function() {
  // this executes in a separate thread.
  // *** NB: it can't reach refer to variables from enclosing scope.
  var path = require('path')

  process.on('data', function(data) {
    // console.log works too!
    console.log('wuh oh')

    process.send(path.join(ev.data[0], ev.data[1]))
  })

  // you can even exit!
  process.exit(0)
}, __dirname)

worker.on('data', function(data) {
  console.log(ev.data)
})

worker.send(['hey', 'there'])

// works with pipes, too
fs.createReadStream('file', 'utf8')
  .pipe(worker(function() {
    process.on('data', function(data) {
      process.send(data.toUpperCase())
    })    
  }))
  .pipe(process.stdout)

API

spawn = require('bfy-worker')

return the spawn function.

spawn(functionOrString, workingDir) -> new Worker

creates a new web worker from the provided function or string, places it at workingDir relative to the rest of your modules, and returns a new web worker.

behind the scenes, it rebuilds the bundle you're operating within and creates an object url using the blob api, and passes the new object url to the worker constructor (so you don't have to host files at specific locations!) it caches object urls by workingDir === workingDir && fn === fn.
