Building a grocery list app has never been easier, especially when using powerful tools like React Native, Redux, and Firebase. In this tutorial, we’ll guide you through the process step by step to create a seamless experience for both iOS and Android platforms!

Prerequisites

• OS X macOS
• Node.js version 10
• Xcode version 10
• Android SDK
• A Firebase account

Getting Started

Before you dive into coding, it’s crucial to have your Firebase account ready. Ensure that your database security rules are set to public since this app doesn’t incorporate an authentication system. To do this:

rules: {
    .read: true,
    .write: true
}

Installation Steps

Follow these steps to install and set up your grocery list app:

1. Clone the Repository

git clone https://github.com/bruz/react-native-redux-groceries.git groceries

2. Navigate into the Directory

cd groceries

3. Install Dependencies

npm install

4. Configure Firebase Credentials

Copy the example configuration file:

cp config.js.example config.js

Then, update config.js with your Firebase app credentials.

Development

For development, follow the React Native Getting Started guide for detailed instructions.

Building and Installing

For iOS Devices

To run your app on an iOS device:

• Open Xcode.
• Go to Product – Scheme – Edit Scheme, then change the build configuration to Release.
• Select your device and hit Run.
• To switch back to development mode, revert the Build Configuration to Debug.

For Android Devices

For Android, follow the React Native APK Signing Instructions.

Troubleshooting

If you encounter any issues during the installation or running of the app, here are a few troubleshooting tips:

• Ensure that Node.js is properly installed and that your version is compatible (Node 10).
• Check that your Firebase rules are set correctly as specified earlier.
• For any unexpected errors, try deleting the node_modules folder and running npm install again.
