Every time I create a new Rails API with a PostgreSQL database, I find myself googling “create a new Rails API with a PostgreSQL database”. So I’m leaving these notes here for myself, and anyone else who finds this helpful.
I like using PostgreSQL for my database because Heroku likes PostgreSQL, and I like making my Rails app an API-only application because I’ll be creating a separate React frontend for my app, so I don’t need a bunch of empty Views folders in my Rails app, since I won’t be using them.
For the purpose of this tutorial, let’s imagine we’re creating a super awesome app, and we’re going to call it Super Awesome App.
1) create folder
2) cd into that folder
3) make sure your Rails version is up to date
For the hell of it, make sure your Rails version is up to date before creating a new Rails app. This seems like a good best practice, so why not.
rails -vgem update rails
4) create new rails API with a PostgreSQL database
rails new super-awesome-api --api --database=postgresql
This will create a Rails project directory named super-awesome-api.
Note 1: you can give your Rails project any name you want. In other words:
rails new project-name-here --api --database=postgresql
Note 2: I plan on creating another directory later, called super-awesome-client, where I’ll be creating my Super Awesome App’s React frontend.
5) cd into your new Rails folder
6) create a Git repo for your Rails app
Don’t forget to keep track of your Rails app’s development on GitHub! Now’s a good time to create a new Git repo for your Rails app.
7) celebrate for ten seconds, then get to work
That’s it! You just built a new Rails app! It’s an API-only application, and it’s all set for a PostgreSQL database. Pump your fist and nod your head and maybe scream: “I DID IT!” Then get to work, you’ve only just begun.
Thanks for reading, nerds!
