Backend Web Development Tutorial: From REST API using Flask to Swagger
Instead of using a website builder, we’re starting from scratch (well… almost) by setting up our own backend REST API using Python and Flask. We’ll walk through the structure of a real backend project, explore API endpoints, database layers, environment setup, and finally run everything locally looking at Swagger.
You can follow along to practice your Python, Flask, and backend fundamentals, or just watch to understand how a backend API is structured and how all the pieces fit together. We’ll use one of my old projects as a starter kit, poke around the code, fix things that break (they will), and test endpoints using Swagger — no frontend required.
This video focuses entirely on the backend, so grab some coffee ☕ and let’s build some tech magic.
