About the + appending to the folder name

[HuyAms]

Hi,

I am checking this document about the + appending to the folder name
https://github.com/kiliman/remix-flat-routes?tab=readme-ov-file#nested-folders-with-flat-files-convention--new-in-v051

Why the project folder doesn't have the + but the users does?

When checking the routes, it looks quite the same to me

 <Route path="project" file="routes-hybrid-files/project/_layout.tsx">
      <Route
        path="parent/child"
        file="routes-hybrid-files/project/parent.child/index.tsx"
      >
        <Route
          path="grandchild"
          file="routes-hybrid-files/project/parent.child.grandchild/index.tsx"
        />
     </Route>
</Route>


<Route path="users" file="routes-hybrid-files/users+/_layout.tsx">
      <Route path=":userId" file="routes-hybrid-files/users+/$userId.tsx" />
      <Route
        path=":userId/edit"
        file="routes-hybrid-files/users+/$userId_.edit.tsx"
      />
      <Route index file="routes-hybrid-files/users+/index.tsx" />
</Route>

Could anyone kindly explain it to me?

Thank you so much!

The project folder should have a +, since it's nested, not colocated.

The reason it currently works is due to a bug where it treats interior / as though it were .. Only the final naked folder is treated as a colocated folder.

remix-flat-routes converts the route into the v2 flat routes convention before processing. This is to ensure that it will always be backwards compatible with the official Remix convention.

That is why routes/project/parent.child.grandchild/styles.css is treated as routes/project.parent.child.grandchild/styles.css and is considered a colocated file.

Since this bug is probably inadvertently depended on, once it's fixed I will add a config option to opt-in to it.
