Building a Python app is exciting—but sharing it with the world is even better. Heroku is a beginner-friendly platform that lets you deploy your Python web apps in just a few minutes. This guide will walk you through the step-by-step process to get your project online fast.
Why Deploy on Heroku?
- Easy setup with Git
- Free tier available for small projects
- Supports Python, Flask, Django, and more
- Great for showcasing projects and prototypes
Prerequisites
Before you begin, make sure you have:
- A working Python web app (e.g., built with Flask or Django)
- Python installed on your system
- Git installed
- A free Heroku account
Step 1: Prepare Your App
For Flask apps, make sure your main file looks something like this:
python
Copy code
from flask import Flask
app = Flask(__name__)
@app.route(“/”)
def home():
return “Hello, Heroku!”
if __name__ == “__main__”:
app.run()
Step 2: Create Required Files
requirements.txt
bash
Copy code
pip freeze > requirements.txt
Procfile
Create a file named Procfile (no extension) with this line:
makefile
Copy code
web: python app.py
✅ Replace app.py with your actual entry file name.
Step 3: Initialize Git and Commit
bash
Copy code
git init
git add .
git commit -m “Initial commit”
Step 4: Deploy to Heroku
- Login to Heroku:
bash
Copy code
heroku login
- Create a Heroku App:
bash
Copy code
heroku create your-app-name
- Push Your Code:
bash
Copy code
git push heroku master
- Open in Browser:
bash
Copy code
heroku open
Your app should now be live!
Troubleshooting Tips
- Make sure your requirements.txt includes gunicorn if needed for production
- Use heroku logs –tail to view real-time logs
- Use heroku ps:scale web=1 if the dyno is sleeping
Practice Tip
Try deploying a simple to-do app, chatbot, or portfolio site. Heroku makes it easy to test real-world deployment scenarios—even as a beginner.
