Deploy a FastAPI Backend on Render | Environment Variables & Production API Testing

In Day 27 of the 30-Day Real Software Development Skills Sprint, we take our FastAPI backend from localhost to a public production URL. This lesson focuses on backend hosting, environment variables, deployment logs, and production API testing. In this practical tutorial, you will learn how to: Prepare a FastAPI project for deployment Push the backend code to GitHub Deploy the API on Render Configure build and start commands Add environment variables securely Read deployment logs Test /health, /courses, and /docs in production Trigger automatic redeployment after pushing a new change By the end of the video, your backend will no longer work only on your computer. It will have a public URL that can be used by a deployed frontend, Postman, Thunder Client, or any other client application. Production start command uvicorn main:app --host 0.0.0.0 --port $PORT Student task Deploy your own backend API, add an APP_ENV environment variable, test the production endpoints, and submit your live /health URL. #FastAPI #Render #BackendDevelopment #Python #APIDeployment #WebDevelopment #Programming #SoftwareEngineering #DevOps
