feat: transpile typescript code instead of transform

TODO:

• remove quote handling
• remove custom transformer for <template>
• consider using oxidase in the mkdist plugin as well: I think it is safe to replace it

Intresting. Have you comparared oxidase with oxc-transform? The former is more actively maintained and is from original author. /cc @Boshen

Yes, maintainer activity is one of my primary considerations when choosing a replacement.

Our use case is quite special: we can’t provide sufficient context to transformers, so they often inadvertently modify our code. For example, even replacing quotes can cause issues. We need to avoid any optimizations introduced by transformers entirely.

oxidase fits perfectly—it strips TypeScript syntax quickly and effectively without unnecessary transformations. It also keep the code position and save us additional work on sourcemap.

Given these reasons, oxidase is an ideal solution for us.

oxidase was an experiment. It is not maintained. The author now works with us on another project.

@Boshen Is the another project some kind of transpiler? I know our use case is niche, but it's pity that oxidase is no longer maintained.

I tried oxc-parser, but unfortunately the AST it provided lost a lot of keyword position information. (e.g. readonly, public, private and ?)

If we want to strip these keywords accurately, we need to call TypeScript's scanner, which is not much different from ts-blank-space (We also need an additional oxc-parser dependency)

@danielroe What do you think about switching to ts-blank-space?

[Teages]

I make a lib with oxc-parser for transpiling https://github.com/Teages/oxc-blank-space

It passed all test from ts-blank-space and enum test from oxidase (ts-blank-space does not support enum).

I haven't done any bench yet, because the performance improve may be not obvious before we migrate to rust. But I think this would be a good start for switching to "transpile".
