If this issue only occurs in one browser, which browser is a problem?

Describe the Bug

For my site, I use the "directory" format: https://example.com/page/

I would like to have my RSS feed like this as well: https://example.com/feed/

But I can't find any combination of the generating endpoint file name, trailingSlash and build.format to achieve this.

File /pages/feed.js, trailingSlash: always, build.format: directory:
-> DEV: /feed has a 404, /feed/ works. PROD: Generates /feed file, /feed/ has a 404

File /pages/feed/index.js, trailingSlash: always, build.format: directory:
-> Same behaviour as /pages/feed.js

If it's not possible to put an RSS feed as a directory, I would be kind of content with just using /rss.xml, but that has it's own problem: It is not reachable on the DEV server any more.

File /pages/rss.xml.js, trailingSlash: always, build.format: directory:
-> DEV: /rss.xml has a 404, /rss.xml/ works. PROD: Generates /rss.xml file, /rss.xml/ has a 404

What's the expected result?

There should be a combination of trailingShash and build.format that behaves consistently for DEV and PROD for endpoint routes.

Have you tried the build format preserve? https://docs.astro.build/en/reference/configuration-reference/#buildformat

I think that's what you're looking for...

I've tried that one as well, the result is still the same for the feed:

File pages/feed.js, trailingSlash: always, build.format: preserve:

• DEV
  • /feed: 404 error
  • /feed/: Shows the RSS
• PROD
  • /feed: Shows the RSS
  • /feed/: 404 error

Also, all other links show in file style (e.g. https://example.com/blog instead of https://example.com/blog/) now, which is not what I want.

It seems like for endpoint rules (xyz.js files), no matter what is set as build.format, the output is always xyz.

feed.js > feed
feed.xml.js > feed.xml
feed/index.js > feed
feed.xml/index.js > feed.xml
feed.xml/index.html.js > feed.xml.html

All output is always in the root, no directory is created.

Ok, I know what's the issue, and it's not the first one.

The issue is that we impose trailingSlash on endpoints too. It's not the first issue that was filed, however we can't change the behaviour lightly.

We plan to change this behaviour in Astro 5.0, by not applying trailingSlash to endpoints. This will be a breaking change.

The only workaround that I can suggest is to change is to use trailingSlash: ignore, however I know that probably won't solve your issue.
