    parallel-worker Build Status

    Get a worker or spawned node process to which you can talk to using a message channel.

    Works in the browser and node.

    function mode

    Call worker(fn) with your function. It should synchronously return a value, or return a promise for a value.

    const result = await worker(item => item + 1)
    assert.equal(result, 2)

    async mode

    Send and receive messages to and from the worker.

    Use the stdout and stderr events to subscribe to stdout and stderr streams on the worker, if you're in node. Subscribing to stdout and stderr does not work in the browser.

    const w = worker.async((onMessage, send) => {
      onMessage(function (msg) {
        send(msg + 1)
      })
    })
     
    w.send(1)
     
    w.on('stdout', (d) => {
      console.log(d)
    })
    w.on('stderr', (d) => {
      console.error(d)
    })
    w.on('message', function (msg) {
      assert.equal(msg, 2)
    })
     
    // ...
     
    w.stop()

    strings instead of functions

    You can always use a string with a function instead of a real function. This is useful because you may want to require other modules with webpack.
