Current behavior

The onSuccess hook runs once for every build config. In this example, ./prepareNpmEntrypoints.sh will run twice.

// tsup.config.ts
export default defineConfig([
  { /* ... */ },
  { /* ... */ },
]);

pnpm tsup --watch --onSuccess "./prepareNpmEntrypoints.sh"

Feature request

A hook that runs once, when all of the builds have completed. This can be used, for instance, to run a script that patches up the build products in some way that's not possible to do during the build.
