What is domDependencyConfig.json

[mrtry]

I want to use react-native-vector-icon.
Tried install, Got the following error.

What is domDependencyConfig.json ...?

$ yarn add react-native-vector
$ react-native link react-native-vector-icons
rnpm-install ERR! ERRPACKAGEJSON No package found. Are you sure this is a React Native project?

Could not find domDependencyConfig.json in your project, please add it.

Experienced this too, are there any hacks or solutions yet?

I did touch domDependencyConfig.json and the error went away. YMMV.

That really not fix the issue, because react-native-dom still depends on native-module to be ported to the web.
For the future, we need to somehow do:

1. react-native link to generate dependencies for the web.
2. react-native-web to somehow take react-native link to use the web-version instead of native module.

Isn't the list of "native modules" in dom/bootstrap.js equivalent to what react-native link does for the iOS and Android build systems?

[anhdle14]

Haven't got the chance to look into the issue but in short: yes

import { RNDomInstance } from "react-native-dom";
import { name as appName } from "../app.json";

// Path to RN Bundle Entrypoint ================================================
const rnBundlePath = "./entry.bundle?platform=dom&dev=true";

// React Native DOM Runtime Options =============================================
const ReactNativeDomOptions = {
  enableHotReload: false,
  nativeModules: []
};

// App Initialization ============================================================
const app = new RNDomInstance(
  rnBundlePath,
  appName,
  document.body,
  ReactNativeDomOptions
);

app.start();

Haven't try to do index.dom.js to see if we can use react-native-web to do the render with non native modules, and let react-native handle gesture, yoga (flex). That would be a most optimal way for now. I could be wrong, but it is good to try it nonetheless.
