Preact: React-Native-Web support

[brunolemos]

Tried using Preact X with react-native-web, but got this error:

react-dom-unstable-native-dependencies.development.js:1700 Uncaught TypeError: Cannot read property 'Events' of undefined
    at react-dom-unstable-native-dependencies.development.js:1700

> 1700 | var _ReactDOM$__SECRET_IN = ReactDOM.__SECRET_INTERNALS_DO_NOT_USE_OR_YOU_WILL_BE_FIRED.Events;

This is because rnw makes references to unstable-native-dependencies. It seems to use 3 items from this file: injectEventPluginsByName, ResponderEventPlugin and ResponderTouchHistoryStore.

Is it possible to make this work or planned to support this use case?

_Here's my project with the branch preact: https://github.com/devhubapp/devhub/tree/preact You can clone and run yarn && yarn dev:web if you wanna try._

The event responder APIs is react's latest version of their own event system. One of Preact's main goals is to use the native DOM event system instead. It's very unlikely that we'll add support for such a system and won't support react-native or derived projects like react-native-web any time soon. We're mainly focused on supporting the web directly without intermediate abstractions :slightly_smiling_face:

I wrote a plugin to implement the Gesture Responder System for preact and react-native-web, feel free trying it. https://github.com/duxiaofeng-github/preact-responder-event-plugin

Thanks for this. To assist people who are encountering errors while using Webpack to build react-native-web projects using Preact X, @duxiaofeng-github 's plugin fixes this error:

Be sure to add the alias as described in the "Usage" section of the docs:

https://www.npmjs.com/package/preact-responder-event-plugin

Hopefully this will add a little Google-juice for people like me who are new to RNW and stumbling on this error.
