Node.js in Production

By on in Development, Ops

When running a node application in production, you need to keep stability, performance, security, and maintainability in mind. Outlined here is what I think are the best practices for putting node.js into production.

By the end of this guide, this setup will include 3 servers: a load balancer (lb) and 2 app servers (app1 and app2). The load balancer will health check and balance traffic between the servers. The app servers will be using a combination of systemd and node cluster to load balance and route traffic around multiple node processes on the server. Deploys will be a one-line command from the developer’s laptop and cause zero downtime or request failures.

It will look roughly like this:

Roll Your Own Asset Pipeline with Gulp

By on in Development

I’ve found myself using Gulp for just about everything involving HTML/CSS/JS these days. It’s super fast, quick to write scripts for and flexible. I’m at a point now where I have a ton of projects I can just cd into, run gulp and be up and running. It’s the best solution I’ve found for delivering static assets whether for local development or production.

If you haven’t used a tool like this before, you might be thinking that your cobbled together scripts (or Asset Pipeline) work just fine. The value of using Gulp is not within its ability to concatenate files, minify files or any of that. Gulp’s true value lies in its ability to compose these things well. Using disparate components might make it easy to concatenate JS, but mixing that in with Rev will immediately compound the complexity of your home-grown scripts. It’s value compared to Asset Pipeline is that it is still flexible.

If you’ve been on Rails’ Asset Pipeline, or on a totally different stack, Gulp should offer you a great solution to static asset compilation. Here’s how:
