Experimental Decorator/s support

[1a35e1]

Hi all,

Great tool, took it for a spin on a pretty large NestJS project. Given experimentalDecorators has been on the standards track for a while I can appreciate, why some this is not working 100% yet.

In NestJS, its relatively common to have parameters injected in the constructor() or a method()

It would be good if we could have a way to disable this warning/error while the API is in flux.

Currently I get Decorators are not valid here.biome(parse) which would be nice to ignore for now.

Will be trying this on a ReactNative project next.

Thanks for the great work!

We support experimental decorators: https://biomejs.dev/reference/configuration/#javascriptparserunsafeparameterdecoratorsenabled

Ah just found it. TYVM.

Just needed to add this!

...
"javascript": {
    "parser": {
      "unsafeParameterDecoratorsEnabled": true
    }
  },
....

For some reason, this is not working for me. I'm using v1.9.4 in a Nest.js project

Maybe you need to restart the server.

Biome: restart LSP server.

It works for me. (v1.9.4)

UPD: I have the same error in JB Webstorm:

unsafeParameterDecoratorsEnabled is enabled:

Restarting the server does not fix anything:

Restart LSP server form actions fix this issue for 1 second and then this error reappears.

I dunno why this is happening but this is affecting our project at work.

For now, I see only one solution: disable Biome plugin and run biome check --fix manually. 😢
