When I built my first React Native app, I had some prior web experience. Using React on iOS and Android felt like a natural way to apply my skills.

But I was suprised to learn, the hard way, that my web-developer-way-of-thinking didn't apply to native apps.

To understand why, let's start with the navigation layout. Each website has unique page primitives. The header at the top of the page, the sidebar menu, the footers – they're all hand-rolled.

You write a <header> and all you get is an empty box. You then use your own JavaScript and CSS to make it useful.

The way these elements look and feel is part of your brand. If your header looks just like another website, something feels off.

Add the package name you want to your package.json dependencies, and then make the value npm:<actual-package-name>. You can also add a version to the end.

package.json

{
  "dependencies": {
    "moti18": "npm:[email protected]"
  }
}

First, copy the config plugin from this repo: https://github.com/gaishimo/eas-widget-example

You can reference my PRs there too (which, at the time of writing, aren't merged).

After adding the config plugin (see app.json) with your dev team ID, as well as a bundle ID, you can edit the widget folder to edit your code. Then npx expo run:ios (or npx expo run:android).

Workflow

After npx expo run:ios, open the ios folder, and open the file that ends in .xcworkspace in XCode. Make sure you have the latest macOS and XCode versions. If you don't, everything will break.
