How to Use Heroku
Sign up for Heroku: Create a free Heroku account by visiting signup.heroku.com. The signup form is straightforward and takes less than a minute to fill. You'll get free dyno hours for running free apps.
Install Heroku CLI: Download and install the Heroku Command Line Interface (CLI) from Heroku's website. This will allow you to manage your apps from the terminal. For Windows users, you may need to click 'More info' and 'Run anyway' if you see a security warning.
Login to Heroku CLI: Open terminal/command prompt and run 'heroku login'. This will open your browser for authentication. After verifying credentials, the CLI will log you in automatically.
Create a new Heroku app: Run 'heroku create' to create a new app on Heroku. This will generate a random name for your app and create a git remote called 'heroku'.
Prepare your application: Create a Procfile in your app's root directory to tell Heroku what commands to run. For web apps, include 'web: command-to-start-app'. Also ensure your app listens on the port specified by Heroku's PORT environment variable.
Deploy your application: Use Git to deploy: 1) git add . 2) git commit -m 'initial commit' 3) git push heroku master. Alternatively, connect your GitHub repository through Heroku's dashboard for automatic deployments.
Configure add-ons: Add databases or other services through the Resources tab in Heroku dashboard or via CLI. For example, 'heroku addons:create heroku-postgresql' to add a PostgreSQL database.
Monitor your app: Use 'heroku logs --tail' to view logs. Check app metrics and performance through the Heroku dashboard. Scale dynos up or down as needed using 'heroku ps:scale web=X' where X is the number of dynos.
