Two things happen that make it difficult to run a Node.js process on a non-default port. First, Elastic Beanstalk uses load balancers. When a request hits your EB DNS (your-app.elasticbeanstalk.com) the load balancer directs the traffic to the least utilized instance (assuming you have multiple ec2 instances…
Ran into an interesting problem today in which a method in one of my classes happened to have the same name as a method on my testing framework. I'm pasting a lot of code but highlighting the important details with comments. Contract require_relative './exceptions' require_relative './fulfillment_…
UPDATE: I got it to work. Use inotify on your host machine to watch the directory for changes and run docker exec <container> circusctl restart <circus_process> And since MAC doesn't have inotify, we can use fswatch. brew install fswatch Then we can watch a directory…

The Workflow Let me describe the workflow we were trying to accomplish. We wanted to run tests on every merge into 'master'. If the tests pass, we wanted the code to be automatically pushed to a staging server. Once we verify staging is working properly, we want to merge that…
Check out this XKCD comic and think about what repetitive tasks you could shave seconds off of throughout your day. Props go out to Josh Wyatt for showing me the world of .bash_profile time-saving techniques. The first thing to do is make it convenient to add new shortcuts to…
This is going to be a simple demonstration of using Test Driven Development practices to solve a toy problem. We will use Node for running Javascript in our console. Grunt task-runner for automation. Mocha for our testing framework. Chai for our assertion library. The only thing you need to do…
Now that we know what Docker is and have it installed, let's look at how we can use it to deploy an app. We are working on a project now as part of HackReactor's curriculum. Our project involves a MySQL database and ExpressJS API on the back-end handling basic CRUD…
