@machour Not sure if this is useful / where this could easily be documented, but this also works if your mocks files are written in typescript with some slight changes.

1. Install tsx package npm i -D tsx
2. Update mocks/index.cjs and mocks/handlers.cjs to .ts files
3. Update dev command binode --import=tsx --import ./mocks/index.ts -- @remix-run/dev:remix vite:dev

Hey @mikeybinns, thank you for the tip!
Do you want to open a PR to switch this example's mocks to typescript? Will happily review & merge.
