Comparing Rails and Phoenix: Part I
As I was thinking about this article a few weeks ago, I was excited when I saw that Chris McCord, creator of the Phoenix Framework in Elixir, was on the Elixir Fountain podcast. One of the things they mentioned on the show was that they were tired of the comparison being made between Rails and Phoenix. The bias of coming from a Rails background may cloud your view of the framework and cause you to
GraphQL and Performance in Rails
We looked previously at getting set up with GraphQL on Rails. We defined some queries, some mutations, and had a good time doing so! But what if I told you that with only a few hundred records in the database, it's possible to write a query that brings our server grinding to a halt? In this article, we'll look at three ways to avoid performance issues with GraphQL in your Rails app, and then at a
Realtime with React and Rails
When I was thinking about creating something to showcase using ActionCable (websockets) in a Rails app with React, I first thought of building a chat. But everybody builds a chat. So next, I thought about a realtime dashboard. But then I realized I had no data in this demo app with all but one user (me). So I decided to build a realtime map application that allows you to broadcast your location to
Server Rendering React on Rails
React apps give us incredible power in the browser, and with the react_on_rails gem from the folks at ShakaCode, we now have an easy way to use React inside of our new and existing Rails apps. In a previous article, I talked about how to get up and running with React in your Rails app. In this article, we are going to talk about doing server rendering with our React components inside of Rails. An
Using React Inside Your Rails Apps
I have never felt as productive as I do in Rails. Yet, with front-end seemingly moving further away from server-rendered views toward React, Angular, Vue, and Ember, I was unsure where Rails fit into this picture. Would it be relegated only to apps with "simple" front-ends, where holding things together with jQuery still managed to work, or perhaps to its new API mode, serving up data via RESTful
Replacing Sinatra with Rack in Sidekiq
Sidekiq is one of the first gems that I install when doing a significant Rails project. If you plan to or already have Redis running, it provides an almost effortless ability to process background jobs. Aside from that, I've always thought that one of the most powerful components of Sidekiq was the web UI that it ships with. Prior to Sidekiq 4.2, the Web UI was implemented as a Sinatra app that yo
How to Use Rails Active Job
You're always striving to give your users a better experience when they use your website or application. One of the most important ways to achieve this is by giving them quick server response times. In this article, we'll explore how to use Rails Active Job to enable us to do this through the use of a queuing system. You can also use queues to help normalize traffic spikes or load on the server, a
Level Up Your Security in Rails
I am not a security expert, and the truth is that most other developers aren't either. I haven't created my own hashing or encryption algorithm, I don't know the inner workings of TLS, nor the different ciphers that are available, but that doesn't give me a free pass when it comes to protecting my users and their data. One amazing benefit to using a framework like Rails is that it pays a great dea
Metaprogramming in Ruby
In this article, we'll be looking at a few different aspects of metaprogramming in Ruby. For starters, what is metaprogramming? Metaprogramming is the writing of computer programs with the ability to treat programs as their data. It means that a program could be designed to read, generate, analyze, or transform other programs and even modify itself while running. We'll specifically look at how we
Building a JSON API with Rails 5
Rails is great for making traditional server-rendered web applications. It has support for cookies, sessions, and other browser-specific functionality right out of the box. It's also great for building JSON APIs, but why include a whole bunch of functionality that we aren't going to use if what we want is to simply build a JSON API? That's where using Rails in --api mode comes in handy. It gives u
