Writing full page component

[naqvitalha]

We have an exiting PWA, there are some routes that render components using RNW.

Is it possible to write an NPM module that is a full page size component and import in an existing PWA and run it using RND?
Or, differently put how to integrate with an existing PWA such that few pages render with RND?

While it's certainly a possibility, due to the massive bundle sizes produced from this project I don't think it's going to be a priority to support incremental adoption for the time being.

[naqvitalha]

How big are the bundle sizes right now?

[vincentriemer]

Hello world clocks in at around....500kb....gzipped (lol)

[drejohnson]

Will bundle sizes eventually be smaller?

[vincentriemer]

Hopefully yeah, I think the biggest win could come from metro adding DCE/tree shaking, but it would be also cool if we could investigate if it would be possible to do tree shaking across a web worker

Why not make the production build with webpack? Dev experience can still be great using metro.

[vincentriemer]

Webpack would need to understand the haste @providesModule annotations because that's how this project selectively overrides core components.

EDIT: Not to mention the asset loading behavior which is very react-native/metro specific
