Generating a typescript file

[yxshv]

I generated the ast of a typescript react code using acorn and acorn-ts plugin...
But i am not sure how to generate a tsx code, and not sure if its possible with astring

Did you find anything?

how do you get types in the estree AST anyway?

using acorn-ts

[wooorm]

why use a package name that doesn’t exist 🤷‍♂️ that’s called acorn-typescript.

It will help you to parse typescript script into typeScript AST

A TypeScript AST sounds like it’s not estree.

yeah thats why I closed this issue...

you will probably have to write your own generator, if you want to use it

Thanks for raising that up @yxshv. Being able to generate TypeScript annotations is indeed a useful feature to add. Astring being ESTree-based, it should use an extension of it, such as the one produced by Eslint's TypeScript parser, which adds typeAnnotation properties to existing ESTree node types, and extra nodes for type references and declarations.

Hi @davidbonnet,

First of all, thank you for this amazing library! It has been incredibly useful.

I wanted to suggest adding native TypeScript support to astring. To explore this, I developed a generator that enables TypeScript support for ASTs generated by acorn-typescript or typescript-eslint. Currently, the generator successfully passes all acorn-typescript tests.

While my generator works well, I believe it would be more beneficial to integrate this functionality directly into astring. If you find my approach interesting, I’d be happy to contribute by creating a PR to add native TypeScript support. Let me know your thoughts!

Best regards,
Sahin
