can't import TS in Nuxt serverMiddleware

See original GitHub issue

Using jiti with createRequire in Nuxt, I encountered the following issue:

ERROR  ServerMiddleware Error: Cannot use import statement outside a module                                0

  (function (exports, require, module, __filename, __dirname) { import qs from 'querystring'
  ^^^^^^

It reproduced consistently whenever using jiti for createRequire and going away whenever reverting to esm. It was solved by clearing node_modules/.cache and I have hitherto been unable to reproduce on a new install of Nuxt, even with the same/similar source files: see https://github.com/danielroe/jiti-h2-tests

Hi @danielroe I’ve finally checked repro using JITI_DEBUG it seems api/ts.ts is not passing through jiti so this bug is/was from nuxt/typescript side which doesn’t add .ts to default supported extensions.

Trying with 2.15 ("nuxt-edge": "^2.15.0-26820047.b2e38f5c") everything works good 😃

It is impossible that cache get’s stalled since we check against checksum of file contents. With nuxt-ts, we disable require-engine (since esm was confliciting). I think that could be the root casue.
