It's seem not the main missions of unbuild 👀

[tangyuhui]

I can transpile to ES5 using tsc, but it seems not to work with unbuild.

I agree with @peterroe , since unbuild uses esbuild and esbuild does not support es5, at least not out of the box 🤔 .

If you don't need to handle .Vue files, you could probably try something like tsup which should support es5.
