Environment

Reproduction

Describe the bug

assume we have two route with different method but same routes

router.delete(
  "/:delete",
  defineEventHandler((event) => {
    return getRouterParams(event);
  })
);

router.get(
  "/:get",
  defineEventHandler((event) => {
    return getRouterParams(event);
  })
);

if we GET request on /, it should handle by router.get not router.delete, indeed the handler router.get is handle the request, but the key of getRouterParams return delete instead get

{"delete":"test"}

thank you

Thanks for the report. it is sadly a limitation of radix3 library used in h3 v1. Without native support for HTTP method matching, names can overlap.

Simple workaround is to use same name like /:id for both methods.

With h3 v2 and rou3 this limitation is resolved.
