Software & DevOpsDone with GitHub Copilot 2026-10-26
Generate a FastAPI web app from one Copilot command
The poster gave Copilot Agent Mode a single command to create a Python FastAPI web app and liked previewing the code before committing.
- What They Did
- The poster opened a new folder in VS Code, added an images directory with a few photos, and gave Copilot Agent Mode one prompt: build a Python FastAPI web app with an HTML, Tailwind, and AJAX frontend. The agent then generated the needed files, wrote the code, and ran it while the poster watched; another commenter specifically liked that GitHub’s integration lets you preview code before committing.
- How It Went
- It produced what the poster described as a fully functional image-browsing web app from that single instruction. The thread also notes limits: the poster says the tech is not perfect yet, and other commenters report refusals or mistakes on other tasks.
- Worth Knowing
- The concrete setup the source gives is minimal: a fresh VS Code folder plus an images subfolder with a few photos before issuing the one command.
Try it yourself with GitHub Copilot
Using agent mode, create a Python FastAPI web app that [describe what the app should do, e.g. a to-do list API with endpoints for add, list and delete]. Show me the planned files and code to preview before writing anything to disk or committing. When it's done, the app should run locally with [command, e.g. uvicorn main:app --reload] and I should have instructions to try it.
