Problem & expected behavior (under 200 words)

There were previous issues with import-in-the-middle which are now fixed. The issue now is that import-in-the-middle cannot parse TypeScript and there's no way to get the loaders in the correct order

  "dependencies": {
    "import-in-the-middle": "1.8.0",
    "tsx": "4.11.2",
    "typescript": "5.4.5"
  },

test.ts

import { test } from './another'
console.assert(test)

another.ts

export function test(input: string) {
  return input
}

tsx --loader import-in-the-middle/hook.mjs ./test.ts

Results in an error because import-in-the-middle cannot parse TypeScript:

  raisedAt: 27
}

Looking at the stack before this occurs we can see that the loaders are ordered as follows, which means that the tsx loader is trying to fetch TypeScript code through the iitm loader:

tsx > iitm > default

This is because of the following code which means that --import and --loader args are always registered after tsx own loader: https://github.com/privatenumber/tsx/blob/aa2b639a9bac8ae28a46b847013fda7f5cd4466b/src/run.ts#L36-L46
