Support decorators in .vue files.

[ruojianll]

In newest npm create vue@latest project, we could use decorators after set "experimentalDecorators": true in standalone .ts files. But it couldn't be transformed in .vue files in <script lang="ts"></script>.

I don't know if it's an esbuld issue, could you give me some advices?

Sorry, esbuild has nothing to do with Vue. The content types that esbuild supports are here: https://esbuild.github.io/content-types/. You'll notice that the Vue language is not listed. Decorators are supported in JavaScript and TypeScript, so if Vue uses esbuild to transform JavaScript and/or TypeScript then decorators should work (assuming the target has been configured correctly). But that's up to Vue to make use of. That's not a problem with esbuild.

I'm closing this issue because it's out of scope.
