// this won't ever get imported on native, but we put this file here to make that clear

When I built my first React Native app, I had some some Web experience. Using React on iOS and Android felt like an easy 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.

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. Your then use your own JavaScript and CSS to make these elements useful.

The way these elements function are 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:moti@0.18.0"
  }
}

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.

Babel

Add the following resolutions to your package.json:

{
  "resolutions": {
 "@babel/preset-typescript": "^7.21.0",

This hook lets you use pagination from URQL. I needed a better solution for React Native and infinite lists.

It also has a pullToRefresh option. Since URQL's pull to refreshes are so insanely flickery, I decided to fake this completely, and make it pretend to spin for one second (plenty for most calls).

It comes with typesafety too.

const document = graphql(`
  query Users($limit: Int!, $offset: Int!) {
 users(limit: $limit, offset: $offset) {
