React vs React Native: How Different Are They, Really?
Some development tools for the web are similar (Chrome debugger, mostly) to those for React Native, but other aspects are very different (working with the metro bundler, using Flipper, AsyncStorage debugging, more). Some techniques developers will use are the same (breakpoints and console logging), but others are different (knowing when to restart the packager vs reinstall the app on device).

Setting up React Native Monorepo with Yarn Workspaces
We’re almost done with setting up the project. The last thing in the React Native app is to add watchFolders so metro knows where the linked node_modules are. The shared modules are symlinked by yarn, and since metro doesn’t follow symlinks we need to explicitly say it where the linked node_modules are.

Debugging RN + Expo bare using WebStorm? Would I be better off just killing myself now?
Unfortunately it is what it is... I use intellij instead of webstorm since they're the same thing basically. I spent a shitton of time figuring out how to link a local package i was creating for my app only to discover about this issue that is almost as old as react native itself. (luckily there's rnx-kit that solves the problem). Not to talk about the impossibility to have one goddamn IDE to write both typescript, java and c++. Currently i have to write ts/js in intellij, then i have to switch to android studio to write java/c++.

React Native Monorepo
React Native doesn't play nicely with most monorepo tools out of the box as Metro doesn't support symlinking.

Running React Native everywhere: The Web
Because React Native for Web is a React website, you can use front-end tools to build and run it. For example, you can build it with Webpack or Rollup instead of Metro bundler.

Running React Native everywhere: Android & iOS
Before we can run the app, we still need do one more thing: make metro bundler compatible with Yarn workspaces' hoisting.
Metro bundler is the JavaScript bundler currently used by React Native. One of metro's most famous limitations (and issue number #1 in its GitHub repository) is its inability to follow symlinks. Therefore, since all hoisted libraries (basically all libraries not specified in the nohoist list) are installed in mobile/node_modules as symlinks from /node_modules, metro won't be able to detect them. Additionally, because of this issue, metro won't even be able to resolve other workspaces (e.g., @my-app/app) since they're outside of the mobile directory.

Running React Native everywhere: Yarn Workspaces monorepo
Second, sharing code with other projects (e.g., backend code, web apps) may get complicated. Out-of-the-box, React Native's metro bundler cannot reference code outside of the project's root directory. You can configure it to do so (and we'll do it as well later on). Still, once you do it, you'll also need to ensure dependencies resolution works correctly (to avoid loading two different versions of the same library, for example); which might not be as easy as it may sound.
While it might appear that we can access all modules from the project’s root node_modules, the reality is that build processes sometimes aren't able to traverse symlinks. This problem is especially prominent in React Native apps, where both the metro bundler and the native code can't follow symlinks.

Running React Native everywhere
This is not a "how to create a React Native app" guide. We'll spend most of the time getting our hands dirty by tweaking React Native's metro bundler, customizing Webpack configurations, and learning how monorepos and Yarn workspaces work.
