Getting Started with Heroku​
Step 1: Install Heroku CLI​
Install the Heroku CLI using Homebrew:
brew install heroku
Login to Heroku:
heroku login
Step 2: Initialize a Git Repository​
Navigate to your Vapor project directory and initialize a Git repository:
git init
git add .
git commit -m "Initial commit"
Step 3: Setup Heroku for Vapor​
Initialize Heroku for your Vapor project:
vapor heroku init
Answer the prompts to configure your app, or accept the defaults.
Step 4: Configure PostgreSQL on Heroku​
Add a PostgreSQL database to your Heroku app:
heroku addons:create heroku-postgresql:hobby-dev
This will create a DATABASE_URL environment variable for connecting your app to the database.
Step 5: Create a Procfile​
Create a Procfile in the root of your project to define how Heroku should start your app:
web: Run serve --env production --hostname 0.0.0.0 --port \$PORT
Step 6: Deploy to Heroku​
Push your code to Heroku for deployment:
git push heroku master
Heroku will deploy your app and provide a URL for access.
Step 7: Test Your Deployed API​
Once deployed, test your API by replacing http://0.0.0.0:8080 with your Heroku app’s URL.
Conclusion​
Deploying your Vapor app to Heroku enables you to make your API publicly accessible and scalable. This setup also simplifies database integration using PostgreSQL.
