☕️ Reasoning
The
@auth/sveltekit
adapter currently overwrites any user-definedbasePath
with the default/auth
. This is caused by an unconditional assignment inpackages/frameworks-sveltekit/src/lib/env.ts
.This change replaces the direct assignment (
=
) with the nullish coalescing assignment operator (??=
).This ensures that a user-provided
basePath
in theSvelteKitAuth
configuration is respected, while still falling back to the default/auth
if nobasePath
is provided. This fixes the issue where users setting a custom path (e.g.,/api/auth
) would receive 404 errors because the handler was not listening on the configured route.🧢 Checklist
