We are starting to use Iron.io and their workers for a lot of the tasks that our apps need to do. For example one app needs to scan websites for images and text and report on them. In our case that is 2 workers, one with the code needed to get the text we want and the other images. Another worker runs behat tests to take screenshots and reports back to the called with the results.
Using Iron.io has made this whole process easy and scalable. One request can be for say 100 urls and with Iron.io we can run one worker per url or using the Symfony Process library we can even use a worker to run a multi-threaded processes.
Some of the resources out there like iron`s example are great. And using this library has made it super easy. Below I cover how exactly to set this up. (hopefully this week we will have a Laravel 5 version of it out)
Step 1 Install
Install 4.2 work. (5 might be ready soon)
Set your minimum stability in your composer.json
Then pull in the library
And add this one patch for PHP 5.6 TODO add code snippet
and
And of course as the readme.md notes for Laraworker
As the developer notes this makes a new folder and file
/worker/libs/worker_boot.phpand/worker/ExampleLaraWorker.php
Step 2 Configure
We will use the .env to do configuration not the way noted in the laraworker docs so lets install that. Just use this post to set that up.
So after you are done your, as in the Laraworker docs, we need to set the queue config.
Set Iron.io credentials in app/config/queue.php and set default to iron –> ‘default' => ‘iron',
So yours will look like
Then make your project on Iron and get the Token and Project ID
Step 3 See if Example Worker works
Lets see if the Example works before we move forward.
If it worked you will see
This will upload a worker related queue
Step 4 Make our own worker!
The goal of this worker
- It will get a JSON object of the info needed to do a job
- It will do the job by getting the json file from the S3 file system where it lives (it could live in a db or other location)
- Using the JSON object's callback it will send back the results to the caller
That is it.
This example will be used in real life to later on parse say 100 urls for already created json render tree objects of the urls data including images and text. This job only cares about the text. Cause the job is fairly easy I will be sending to each worker 5 urls to process.
Copy the worker in /workers folder to the new Worker name
Due to bad naming abilities I am calling this RenderTreeTextGrepper.php
So now my worker folder has
But I do not want that class to have all my code so I will start to build out a namespace for all of this and the 2 classes I want to manage ALL of this work.
Class 1 @fire
So the worker will fire the class I have to handle all of this.
then
Then in app/RenderTreeTextGrepperWorker
folder I have
/projects/example_worker/app/RenderTreeTextGrepperWorker/RenderTreeGrepperHandler.php is the class to handle the incoming request and process it.
Class 2 Event Listener
Then I register the event listener with the app/config/app.php to make it easier to handle the results of the output. You can do all of this in class 1as well.
And that is it.

What is it?
So we are going to upload and run this and here is what will happen. NO WAIT!
First lets make a test so we can see locally if all the logic is there.
Local Test
Just a quick test to see if the handler will handle things and pass results
Running this
Produces this
Of course I need to go into more testing for the two classes to see how they react to different data going in but just to see that there are not obvious issues before I upload the worker.

Upload the worker we just made
And then we see on Iron.io
Then we run it
Before that though I updated app/commands/RunWorker.php:26 to make a better payload
We then see the Task
And the example log output
Guzzle and the Callback
Pixa 1 1 3. How to format the callback?
Let's require guzzle
At this point we have a working example. The queue takes the json and the worker processes it!
Thanks to the library and Iron.io it really is that simple.
