Question: ts-creator & TypeScript transformer

[LukasMachetanz]

Hi.

Currently I am fiddling around writing my own custom typescript transformer. In this context I also discovered this package.

I am wondering how or if ts-creator could be used to e.g. insert a node into the ast.

I understand that I get the ast representation with the creator function of the package. But I do not understand how I can use the returned string directly to e.g. insert a node into the ast.

Currently I just use the package as an helper to see what the exact ast representation would be. But it would be really cool if this string could somehow be used directly.

Therefore I just wanted to ask if someone has an idea. I appreciate any help.

Thanks in advance,
Lukas

Hi. Sorry for the delay.

I'm not sure I 100% catch your point.

You cannot insert a node into the ast because the AST is immutable for the source code.

Maybe you can construct another source file(code) and rewrite them into the original file.

And BTW: You can use https://ts-ast-viewer.com/ to explorer the ast. There's more infos.

Thanks for your attention!

It is possible to replace a node when writing a transformer @Kingwl: https://github.com/madou/typescript-transformer-handbook#replacing-a-node

Pd: I currently have the same question as @LukasMachetanz has when I found this issue.
