I develop a cross-platform react-native application inside a monorepo and want to render my app using react-native-web in the browser. To achieve that I followed this guide https://mmazzarolo.com/blog/2021-09-22-running-react-native-everywhere-web/. I’m also using the metro-react-native-babel-preset
package for compiling my web-app, as described in the react-native-web guide https://necolas.github.io/react-native-web/docs/multi-platform/. Here is a part of my craco.config.js file (I use create-react-app with craco):
// craco.config.js
const webpack = require("webpack");
const { getWebpackTools } = require("react-native-monorepo-tools");
const monorepoWebpackTools = getWebpackTools();
module.exports = {
babel: {
presets: ["module:metro-react-native-babel-preset", "@babel/preset-react"]
},
webpack: {
configure: (webpackConfig) => {
// Allow importing from external workspaces.
monorepoWebpackTools.enableWorkspacesResolution(webpackConfig);
// Ensure nohoisted libraries are resolved from this workspace.
monorepoWebpackTools.addNohoistAliases(webpackConfig);
return webpackConfig;
},
Now it seems like the metro-react-native-babel-preset
preset is not compatible with the stylis library (imported by @emotion/react), because I get this error when launching the app in the browser (it compiles without errors):
Uncaught TypeError: (0 , _stylis.middleware) is not a function
at createCache (emotion-cache.browser.esm.js:288)
at Object.../node_modules/@emotion/react/dist/emotion-element-699e6908.browser.esm.js (emotion-element-699e6908.browser.esm.js:11)

at __webpack_require__ (bootstrap:851)
at fn (bootstrap:150)
at Object.../node_modules...
I guess that the stylis-package cannot be imported correctly due to the metro-react-native-babel-preset
preset, since without the preset the error is gone (but the compilation-step throws errors, so removing the preset is not a solution).
What do I have to change in my babel- / webpack-config or code to remove this error?

I think it is a problem with packages version.
When I try it, I also have this error.
But when updated packages to newer version it was gone (other error occured thought, but related to reactDOM).
I have updated react-scripts
to 5.0.0;
See if it helps you as well.

[email protected] is not compatible with craco, I get lots of these errors:
You attempted to import ... which falls outside of the project src/ directory
. I guess this has to be merged first github.com/gsoft-inc/craco/pull/372–
