Split trailingSlash option into two. One for routing and one for export (subFolder)

[jarandmi]

Describe the feature you'd like to request

Today, the trailingSlash config option behaves so when navigating the app it add a "/" to every route, even if it didn't exist in the link. Thats expected behaviour. What it also does is, when exporting static .html files, it creates a subfolder with index.html files, so the routing is targeting the folder, and not the file.

This are two different needs. When hosting on S3, we need the files in folders, so we can get nice and clean URL without .html. But we don't want the trailing slash.

Describe the solution you'd like

{ exportToSubFolders: true, trailingSlash: false }

This makes it possible to host files in folder, but still route/navigate to paths without the trailing slash.

Describe alternatives you've considered

You can try to add rewrite rules to your hosting platform, but adding two different options seems like a way more simpler and logic solution

I also need this exact split 👍
@jarandmi did you find any workaround?

[jarandmi]

@RonnyO I added a 301 redirect in our lambda, if the URL had a trailing slash, so didn't solve it within Next.js

[jarandmi]

I also patched Next so it don't build with .html even if trailingSlash is true

[matthewjamesadam]

I'm statically exporting my next.js site, and need to export pages with the structure /path/to/file/index.html, instead of /path/to/file.html.

I've enabled trailingSlash, which does export files in this structure, but now all my links have a trailing slash, which I don't want. I think it would be great to separate these two features out.

It is not a feature but a market strategy to force you buy their hosting solution instead of using zero cost generic Web Server.

I fix this with patching Next package in yarn
