Prenrendered routes are served with a trailing slash, /prerendered redirects to /prerendered/ because of @react-router/serve static assets handler

[remorses]

express.static will always append a trailing slash to .html files, meaning /path gets redirected to /path/ if /path.html exists.

This is different than normal react-router routes and it's unexpected and can cause serious issues with SEO.

The issues comes from this line: html

Given that this is a non configurable behaviourthe best fix would be to replace express.static with something else, for example sirv .

I just hit this too. It's the second pain point I've felt with the serve package; the first was when trailing slashes were being added to routes whose URL corresponded with static assets in the public directory.

I just hit this as well. For an existing website that doesn't use the leading '/' for their server-side rendered pages, pre-rendering them should just not change how its routing works. And also as the poster says, it's a bit unexpected how accessing the same route in a document request vs client navigation request behaves differently.

I am now using https://github.com/rphlmr/react-router-hono-server to prevent this problem

It uses Hono static server instead of express static, which handles trailing slashes correctly.

It also removes the need for the @react-router/serve package, which is a really bad anti pattern in my opinion, the generated server file is self contained and ready to be executed as is.
