TypeScript 5.8 Beta is released 🎉
🔶 "nodenext" gets require(ESM)
🔶 "nodenext" deprecates Import Assertions
🔷 Checked Conditional Return Types
🔷 erasableSyntaxOnly flag for Node
🔷 Perf: libReplacement flag
🔷 Perf: Program load/update optimizations
We just released the beta for TypeScript 5.8! This release brings support for Node.js' require(ESM), smarter/safer checks for functions using advanced types, a few great optimizations for editor scenarios, and more. Give it a try!

I'm creating `type-annotationify`, a package that transforms your TS code to TS with erasable type-annotations. It already supports constructor parameter properties, enums and <type> assertions. See github.com/nicojs/type-annot…
I'm in the process of adding namespace support 🧵

So, for this approach to work, I would need to transform protected to public and private to either public or #esprivate. Sheesh 😔 🧵

So this is where I now stand.
My idea is to transform classes to use `public` instead of `protected` / `private` and use a local variable shadowing the actual namespace.
Does anyone have suggestions or ideas? Feel free to comment on the issue or here.

I've been working on a small side project: type-annotationify. Migrate full-fledged TypeScript to type-annotated TypeScript compatible with the type annotations proposal and NodeJS's strip-types.

Want to help? Please try it out on your code and let me know what I missed. I'm also looking for projects that use a lot of namespaces, so I can test that out as well (I don't use them myself).
Spread the word; TypeScript is JavaScript with type annotations!

Are you a TS expert? I'm looking for help with namespaces. See this issue:

How can we represent a TS enum in plain type-annotations TS while remaining fully backward compatible? I'm thinking this. I would love some feedback from the community.

Issue here: github.com/nicojs/type-annot…
The `satisfies` operator here is optional but makes it easier for the Type and Value to remain in sync in the future.
Feedback welcome.

Shoutout and thanks to @Vaxilart and Marcelo Shima (github/mshima) for onboarding me, and @kom_256 as another existing maintainer for letting me join on! ❤️
Exciting times for @yeoman: @kom_256 and I are taking on project maintenance! 🎩
Yeoman is one of *the* classic web dev tools. It helped pave the way for many of today's create-*s. We're resuming work to get through backlogs & dependency updates.

Does anyone know of a tool that can convert enums and parameter properties to type-annotations-compliant TypeScript? Otherwise, I might build one. Seems extremely valuable in the long run.

I consider you to be the experts here. Any ideas?
I think automatically converting namespaces is impossible, so I left that out. 🙄
