error with `export type * from`

[stefanprobst]

echo "export type * from './types'" | npx esbuild --loader=ts

results in:

✘ [ERROR] Expected identifier but found "*"

    <stdin>:1:12:
      1 │ export type * from './types'
        ╵             ^

1 error

That's not valid TypeScript. The TypeScript compiler says this:

example.ts:1:1 - error TS1383: Only named exports may use 'export type'.

1 export type * from './types'
  ~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Please check that your code is valid before assuming the problem is with esbuild. Closing this issue as invalid.

oh sorry! this was in generated code so i assumed it was valid. sorry for that, should have checked. the upstream issue for this seems to be microsoft/TypeScript#37238 / microsoft/TypeScript#48508 btw.
