Decorators
✅ Viability Checklist
My suggestion meets these guidelines:
- This wouldn't be a breaking change in existing TypeScript/JavaScript code
- This wouldn't change the runtime behavior of existing JavaScript code
- This could be implemented without emitting different JS based on the types of the expressions
- This isn't a runtime feature (e.g. library functionality, non-ECMAScript syntax with JavaScript output, new syntax sugar for JS, etc.)
- This feature would agree with the rest of TypeScript's Design Goals.
Not sure - this would be badly breaking against your legacy decorators feature, but I think it meets the goal to align TS with JS
⭐ Suggestion
The TypeScript proposal is now Stage 3!!!
https://github.com/tc39/proposal-decorators
We've all seen the issue from hell requesting better typing support for decorators
but now that the proposal is moving forward, currently at Stage 3, I thought I'd open this issue to see if there are plans to finally, fully implement (and type) the ES version of decorators.
📃 Motivating Example
N/A - just implementing new JS features, to keep JS and TS aligned.
💻 Use Cases
All the various ways decorators can be used.
