Ruby on Rails also known as Rails, is a server-side web app framework and is written in Ruby. It makes the development process of web applications easier by making assumptions about what every developer needs to get started. It lets you write less code while you may achieve more than most languages and frameworks would be able to.
Heroku, on the other hand, is a cloud platform as a service (PaaS) supporting several programming languages, including Ruby. It is user-friendly for deploying, managing, and adapting apps. One of its biggest advantages is that it simplifies the complexities of the infrastructure and lets you focus on building your app without worrying about the underlying hardware.
Deploying Ruby on Rails Apps on Heroku
When it comes to web development, deploying Ruby on Rails apps on Heroku can be a difficult task. However, with a step-by-step guide, the process becomes much simpler.
-
Getting the App Ready
Before you think about deployment, ensure your Ruby on Rails app is ready. This means your app should be fully functional in the local development environment. It’s also a good time to consider the scope of your project and whether you need to hire dedicated Ruby on Rails developers to refine your app or add complex features that require expert knowledge.
-
Setting Up Heroku
First things first, you need a Heroku account. Go to Heroku’s website and sign up for free. Once you’ve got your account set up, download and install the Heroku CLI (Command Line Interface) on your computer.
Heroku CLI is an excellent way for you to manage your Heroku apps right from your terminal. After installing the CLI, open your terminal and log in to Heroku using the command heroku login. Follow the prompts to enter your account credentials.
-
Prep the App for Heroku
Heroku requires a bit of setup to get your application ready for deployment:
-
Use PostgreSQL
Heroku prefers PostgreSQL over SQLite3, which is the default database used by Rails. If your app uses SQLite3, you need to switch to PostgreSQL. This involves adding the pg gem to your Gemfile and updating your database configuration.
-
Configure Static Assets
Make sure your app is set up to serve static assets. This usually involves ensuring the appropriate settings in your config/environments/production.rb file are enabled.
-
Procfile
Create a Procfile in your application’s root directory. This file explains Heroku how to run the app. For a basic Rails app, your Procfile might simply contain web: bundle exec puma -C config/puma.rb.
-
Deploying the Application
With your application prepared and your Heroku setup ready, it’s time to deploy:
-
Initialize a Git Repository
Initialize a Git repository in your application’s directory if you haven’t done so already. Heroku uses Git for deployment.
-
Connect the Heroku App
Create a new app on Heroku using the CLI with heroku create. This command also adds a Heroku remote to your Git repository.
-
Deploy the Application
Deploy the application to Heroku by pushing code to the Heroku remote using git push heroku master.
-
Migrate the Database
If your app uses a database, you’ll need to migrate it on Heroku using heroku run rake db:migrate.
-
Visit the Application
Use heroku open to open your application in your browser.
-
Application Management
After deployment, Heroku provides several tools to manage the app:
-
Heroku Dashboard
Heroku dashboard is accessible via Heroku’s website and allows you to monitor the app’s performance, scale it, set environment variables, and more.
-
Heroku CLI
In addition, you can use the CLI to apply configurations, track logs, and run commands on the computing unit performing your app.
-
Add-ons
Heroku offers add-ons to respond to the needs of specific databases, email services, monitoring, and other tools, these tools will allow you to enhance your app`s functionality.
Conclusion
Deploying a Ruby on Rails application on Heroku doesn’t have to be complicated. By following these steps, you can get your app up and running on the web in no time.
