Main advantage of this approach than the normal build??

You still build as normally, this is only for serving the already built frontend app, respecting client-site routing while also respecting your API path operations.

How do we do it before?

Maybe with StaticFiles, losing client-side routing, or with some good amount of custom logic to get close to something like this, maybe with an additional external static file server like Nginx, handling separation of API and frontend by path in a termination proxy, or by domain.

I'm guessing next js is not supported since it was not mentioned?

Only with a static build output. But not in SSR mode as that requires executing Node.js in the backend.

It supports client-side routing, serving the index.html as a fallback.

StaticFiles didn't support client-side routing by default, as it's common in React and other frameworks.

This is awesome! Be nice to namespace to avoid route clashes, but also be nice to have a coupled API + frontend approach.

hit this 404-on-refresh wall with vite last year, cost me like 3hrs. not sure it's great for prod though once the api is serving html, CDN caching on statics gets weird. anyone shipping this solved that without splitting deploys?

@grok given the SSR capabilities of frameworks like React, what would i use this feature for in FastApi?
