![]() You then take that box, create a snapshot of what it looks like, then share that snapshot with your developers. You can think of it as putting your app in a box, where you define everything your application needs to run (e.g. Once your application becomes sufficiently complicated to setup, or requires some very specific versions of software to run, you should consider looking into Docker.ĭocker is a tool which allows you to create a perfect consistent environment for running your application. I’ve also found this approach cumbersome when locally a developer needs to turn on quite a few extra services to experience the full entire application. ![]() One of the drawbacks of this approach is when you need a specific version of Postgres, or your app has non-standard libraries which need to be installed on the developers machine. This approach is perfect for small projects and when you’re learning Ruby on Rails, but it will also work for larger projects where you just need Ruby and a database to do your work. I use the sample file to document on where to find the values (e.g. env file isn’t committed to version control, but instead a. env file in the directory you execute the command & inject the environmental variables into your app. One fun benefit of both of these gems is they will read the. # You can run everything in the Procfile with:īoth Foreman & Overmind are fantastic, so either one you choose is a great choice. More recently, I was shown Overmind which is very similar to Foreman but it runs each service in a TMUX session which means you can start every service, then connect & restart individual services as you require. What I like about it, is it brings back memories of when I used to use MAMP, which offered a really nice way to just start & stop the database locally. ![]() Postgres.app is GUI Mac app for managing Postgres Databases. However, if Docker isn’t your thing I’ve also become a fan of Postgres.app. a legacy project), I’ll often use Docker to pull down a image matching the version I want & then I’ll run that via Docker-Compose as a stand-alone service. When I need a very specific version of Postgres which for a particular project (E.g. I used to install it via Homebrew, but I found two solutions which are much better. ![]() Postgres is the most popular database choice when working with Ruby on Rails. With these 4 commands, you can have Ruby up and running on your machine in no time. point the default ruby executable to the asdf one Once you have asdf installed, you can use the ruby plugin to easily manage the ruby version on your machine. This means you can have a single tool, and be able to install everything from Ruby through to NPM & Yarn. They’re good, but more recently I’ve seen lots of Rubyists switching to asdf.Īsdf is similar to the other tools I listed above, but it allows you to install & manage multiple languages, along with changing the version used on a per folder basis. In the past Rubyists have used RVM, RBenv or chruby to install Ruby. If you’re using MacOS you’re in for a treat, a lot of Rails developers use either MacOS or Linux, so the tooling is generally really fantastic.Īs for Linux & Windows, while some of the tools do somewhat work, I’d suggest skipping straight to using Docker (The next section) as it’ll work without much setup required on those operating systems. In this post, I’m going to cover the tools asdf, Postgres.app, Overmind & Docker which I use to achieve an easy to setup & low maintenance, local Ruby on Rails development environment. However, over the last few years the tooling has drastically improved & getting an enjoyable setup is now a fairly painless experience. One thing holding Ruby on Rails back is that historically Ruby has been quite difficult to install, and a lot of internet commentators have held onto their negative experiences. Web Sockets & Mailers) you’ll need to build a modern applications. ![]() Ruby on Rails is a fantastic framework for building lovely web applications in 2021, mostly because out the box it ships with the majority of the parts (e.g. ![]()
