or @climba03003 are you blocking this?

I think this works now?

For plugins, Yes. All of them should be migrated and works now.

Not blocking

For plugins, Yes. All of them should be migrated and works now.

Only a slight issue with the auto load plugin. But that just needs to be fixed ASAP. And this comment is unrelated and not the answer anyway. For auto load plugin I need to set VITEST environment variable when using ESM in combination with Ts-Node.

See fastify/fastify-autoload#309 (comment) and my original help request: fastify/help#1014 (comment)

A PR to autoload would be amazing

If I knew how to solve ESM detection yes. Sorry I'm not too familiar with autoload and how to detect ESM.

But yes, it's the only plugin that cause issues! So it's the last fastify plugin that needs (re)work for proper ESM support.
