Towards stage 2

[PodaruDragos]

Hello,
This is mainly a question/discussion that I wanted to start.
I am one of the maintainers of inversify which is a DI library . A very very common question we get is "when are we switching to vanilla decorators". Since inversify or mostly other DI libraries are all doing parameter decorations using the experimentalDecorators flag, supporting stage 3 decorators would be close to impossible with the same UX.

The question would be, has anything changed in the statements of tc39 or is this still something with low interest ?

NestJS is also a library which heavily uses DI and parameter decorators, and this feature (along with decorator metadata), are needed to support vanilla decorators. It would enable us to use tooling such as esbuild with NestJS.

According to the maintainer kamilmysliwiec:

"I don't think we'll support JS decorators till the metadata support & parameter decorators are implemented"

Here's a couple issues requesting this feature:

• Support ECMAScript decorators (coming in TypeScript 4.8) nestjs/nest#9558
• Support TC39 decorators that is available since TypeScript 5.0 nestjs/nest#11414

Any news on this?
