Summary

I did a init:

❯ fleek sites init
⚠ Warning! To proceed, please select a project...

✔ Select a project from the list: › manu.nu

✅ Success! You have switched to project "manu.nu" successfully.

✔ We've found existing sites. Would you like to link to one of them? … yes
✔ Select site from the list › nix-manu-nu
✔ Please specify the directory containing the site files to be uploaded … dist
✔ Would you like to include the optional "build" command? … yes
✔ Specify `build` command: … task build
✔ Select a format for saving the site's configuration: › Typescript (fleek.config.ts)

✅ Success! The Fleek configuration file has been successfully saved.

But then the deploy doesn't recognise .ts extension:

❯ fleek sites ci
❌ Error: Validation of loaded /home/manu/dev/manu.nu/fleek.config.ts failed. Unknown file extension ".ts" for /home/manu/dev/manu.nu/fleek.config.ts
💡 Please follow the setup instructions to create a valid configuration file.

? We've found existing sites. Would you like to link to one of them? › (Y/n)
