Route group and layout at top level prevents root index page from being rendered

[octopicorn]

With the following file structure (file based routing):

src/routes/
  (landing-pages)/  <- this is a route group which will not appear in the url path
      _layout/
          index.tsx // <- this is the home page with layout applied
          about.tsx
          contact.tsx
      _layout.tsx // <- this is the layout file

Expected result:
Home page is rendered with the layout applied.

Actual result:
No home page is rendered at all.

If I remove the (landing-pages) route group, rendering works again as expected. There seems to be something about the route group at top level that prevents the route '/' from rendering _layout/index.tsx wrapped by _layout.tsx.

I've reproduced this in a CodePen based off of the Basic example in the docs.

Is layout supposed to work in combination with route groups? Or is it an either/or set of features?

This is a real use case. I want Home and several other pages to share a "top level" layout, let's say a left nav and header. Then I want a set of subpages to share a completely different layout (not inheriting from top level layout at all), like a project workspace with tabs.

I thought route groups might offer me a way to separate these two groups of layout groups, but it seems like there is something about the root index page that doesn't fit this pattern.

looks like a bug in the generator. can you please create an issue with a minimal complete example (fork one of the existing examples on Stackblitz)?

Also trying to have root index nested in a layout to completely separate it from auth & other layouts

Tried couple of ways

tree app/routes
app/routes
├── (auth)
│   └── login.tsx
├── (main)
│   ├── _layout
│   │   └── index.tsx
│   └── _layout.tsx
└── __root.tsx

tree app/routes
app/routes
├── (auth)
│   └── login.tsx
├── (main)
│   └── index.tsx
├── _(main).tsx
└── __root.tsx

tree app/routes
app/routes
├── (auth)
│   └── login.tsx
├── _main
│   └── index.tsx
├── _main.tsx
└── __root.tsx

Actually while writing this I got the 1. approach kinda working in Stackblitz tho navigating causes different errors https://stackblitz.com/edit/github-3ber8h locally I can't get it working at all

Also played around with the routeToken approach using the default and changing it to layout as suggested here #1102 (comment) tho still failing

Tried this one as it looks promising https://github.com/SeanCassiere/nv-rental-clone/blob/master/src/routes/_auth/(dashboard)/_index.tsx

with the following tsr settings

indexToken: "_index",
routeToken: "_route",

tho I get the following error when navigating to any route within _main where _index.tsx lives in my case. routeTree.gen looks good to me

this is just an exerpt the full trace is quite long

removed token config and renamed to index.tsx still same error

[schiller-manuel]

can you please create a minimal router-only example and create a new issue for this?

[CanRau]

actually can't reproduce anymore ^^
not sure it's because of the latest updates or something else in repo 🤷🏼

Update: yea something with my repo, just started a new one, even patched my PR #2734 in and having index.tsx nested within pathless routes & groups works just fine 😅

tested examples 1 & 3 (#1457 (comment)) and even a variation of 3 where index.tsx within _main is nested in a pathless group (inner)

[schiller-manuel]

great, so we can close this? :D

[CanRau]

At least regarding my stuff yes, not sure about OP
