Acorn is built using React Native, but it's only designed with iOS in mind. And thus, you'll need a Mac to run Acorn locally.

This guide should cover the basic setup for React Native development, which includes Xcode, Node.js, and Watchman.

Then you need these four dependencies;

You can install EAS CLI using NPM and the rest using Homebrew.

• Bun
• EAS CLI
• Fastlane
• CocoaPods

And finally, an Expo account.

Once you download Xcode from App Store, open Terminal and install the rest of the dependencies;

brew install fastlane cocoapods watchman node oven-sh/bun/bun
npm i -g eas-cli

For development / personal builds, you don't need any environment variables. But since the build scripts expect .env files, you can create them by running these commands in the apps/mobile directory;

touch .env.local
touch .env.production.local

git clone https://github.com/alizahid/acorn.git
cd acorn

bun i

You can either run bun dev from the project root, which will spin up both the mobile and web apps.

Or you can navigate to apps/mobile and run bun dev there, which will only spin up the mobile app.

It's preferred to run bun dev from from the project root so we can clear cache before spinning up the apps.

Here's how you can generate a build for simulator while developing;

1. Run bun build:sim inside apps/mobile
2. EAS Build will generate a compressed archive. Extract Acorn.app from it
3. Drag and drop Acorn.app into your simulator
4. Run bun dev at the root or inside apps/mobile
5. Done

Building for production (for your own device) is pretty much the same as building for development;

1. Run bun build:preview inside apps/mobile
2. EAS CLI will guide you through setting up your Expo project and Apple developer account credentials. Make sure to register your devices with Apple through Expo
3. EAS Build will generate a build.ipa file
4. You can now AirDrop the build.ipa to your devices, or use Xcode to install them
5. Done

Acorn uses Biome to lint and format code.

You can run the following command at the root of your repo to make sure things are how they should be;

bun lint; bun lint:types
