I'm not actually sure removing the warning is correct; the intended behavior may be for server.ts to be invalid inside the routes directory. If it is actually incorrect, we'd probably want to remove this warning altogether as technically page.ts would be allowed as well.

[sacrosanctic]

foo.server.ts is allowed inside src/routes. So I would assume server.ts is ok as well.

There’s going to be two groups of people: those who did it on purpose and those who did it on accident. I assume we added the warning because an issue was raised about it. Maybe we can make the warning more resilient by checking for the relevant exports before warning

[sacrosanctic]

On second thought, I don't want to move the warning. But be able to silence the warning when it is intentional.

Please give an option to silence it. I would love to use this pattern hyunbinseo/svelte-kit-template@ea819f7

Name remote modules remote.ts or *.remote.ts, outside server/ directories. They export only remote functions — move other exports to separate files:

src/routes/posts/new/
├── save-draft.remote.ts
└── create-post/
    ├── remote.ts
    ├── server.ts # server-only (e.g. db access)
    └── shared.ts # isomorphic (e.g. schemas)
