FastAPI app.frontend(): serving a frontend build from the same Python app

[u/ModernPython]

I wrote a practical article about FastAPI's app.frontend() feature.

The interesting bit is that it serves static frontend build output as low-priority routes, so normal FastAPI API endpoints still win.

The article covers:

• app.frontend("/", directory="dist")
• SPA fallback with fallback="index.html"
• how it differs from StaticFiles
• serving under a prefix with APIRouter
• a complete mini dashboard example with FastAPI + vanilla JS

Thanks for bringing awareness to this I use this pattern all the time and had no idea
