In the realm of modern applications, React Native has emerged as a prominent framework, especially when augmented with AI capabilities. This guide walks you through creating a full-stack mobile application that supports Large Language Models (LLMs), real-time streaming text interactions, image services, and natural language processing to manipulate images. Let’s unlock the potential of React Native AI!

Features of React Native AI

• Seamless LLM support for various platforms including OpenAI ChatGPT, Anthropic Claude, and Cohere.
• Real-time streaming responses and easy integration of new features.
• Customization through theming with defaults and the ability to add new themes effortlessly.
• Powerful image processing capabilities via ByteScale.

Getting Started

To embark on your React Native AI journey, follow these steps:

1. Generate a New Project

To create your project, run the following command:

npx rn-ai

2. Configure Your Environment

You have the option to configure your environment variables at this stage, or you can choose to do so later. This flexibility allows you to set up everything according to your specific needs.

3. Running Your Application

Once your project is set up, navigate into the app directory and start your application with:

npm start

4. Running the Server

Similarly, change into the server directory and run:

npm run dev

Theming Your Application

Customization is key to a good user experience. To add a new theme, access apps/src/theme.ts. Here’s how you can create a stunning theme:

const christmas = { ...lightTheme, name: "Christmas", label: "christmas", tintColor: "#ff0000", textColor: "#378b29", tabBarActiveTintColor: "#378b29", tabBarInactiveTintColor: "#ff0000", placeholderTextColor: "#378b29" };

Don’t forget to export this wonderful theme at the bottom of your file.

export { lightTheme, darkTheme, hackerNews, miami, vercel, christmas };

Configuring LLM Models

Integrating and managing your LLM models can be likened to arranging books in a library. You want to have them well-organized for easy access and use. Here’s how you can do that:

• Update the MODELS in constants.ts to add or remove models.
• For every new model added, you must ensure that src/screens/chat.tsx understands how to interact with it:
• Create a local state for the model data.
• Modify the chat() function for new model types.
• Update relevant functions and UI rendering to incorporate the new model.

Adding Image Models

To integrate image models, the strategy mirrors that of LLM models. You can modify IMAGE_MODELS in constants.ts, ensuring the configuration matches the input requirements. Remember:

• If a model accepts both text and images, the app must be registered to handle both inputs.
• Update your server configurations similarly as you did for LLM models to accommodate the new image handling.

Troubleshooting Common Issues

While building your application, you may encounter some bumps along the road. Here are some troubleshooting tips:

• Ensure that all environment variables are correctly set before running the application.
• If your models aren’t recognized, double-check that they’ve been correctly added to both the app and server configurations.
• If you experience performance issues, consider optimizing your image processing functions.
