I think that `composes` is related for current config. Is it possible fixed in current config? Or we need use 19 version or fix it in locally?

You can use the exports map. example: https://github.com/preactjs/preact/blob/4aaecc18d33a9f3139ddd5f30f6d7c745076795f/package.json#L12-L18 And build a few entry point for each export variant example with Rollup.js : https://github.com/shoonia/storeon-velo/blob/master/rollup.config.js#L22-L38 Playground: [https://rollupjs.org/repl/](https://rollupjs.org/repl/?version=2.58.0&shareable=JTdCJTIybW9kdWxlcyUyMiUzQSU1QiU3QiUyMm5hbWUlMjIlM0ElMjJtYWluLmpzJTIyJTJDJTIyY29kZSUyMiUzQSUyMmV4cG9ydCUyMGNvbnN0JTIwY291bnRkb3duJTIwJTNEJTIwZnVuY3Rpb24lMjAoKSUyMCU3QiU1Q24lNUN0JTJGJTJGJTIwQm9keSUyMC4uLiU1Q24lN0QlMjIlMkMlMjJpc0VudHJ5JTIyJTNBdHJ1ZSU3RCU1RCUyQyUyMm9wdGlvbnMlMjIlM0ElN0IlMjJmb3JtYXQlMjIlM0ElMjJlcyUyMiUyQyUyMm5hbWUlMjIlM0ElMjJteUJ1bmRsZSUyMiUyQyUyMmFtZCUyMiUzQSU3QiUyMmlkJTIyJTNBJTIyJTIyJTdEJTJDJTIyZ2xvYmFscyUyMiUzQSU3QiU3RCU3RCUyQyUyMmV4YW1wbGUlMjIlM0FudWxsJTdE)

I spent some times to understand how to generate one pixel png image with bytes. Unfortunately I don't have some clear algorithm how to do it.
