React Native & AI: Build Image Generator Apps with Expo

Set up the environment for React Native with Expo, install Node.js, and create your first Expo app using the blank template to run on Android or iOS.

Open Expo React Native project in Visual Studio Code, organize assets and app.js, start with npm start, then run on real devices by scanning a QR code with Expo.

Learn to run a React Native Expo app on Android and iOS virtual devices by setting up Android Studio, creating a virtual device, and launching via Expo on iOS simulator.

Build a React Native image generator GUI with Expo by adding a text input, a generate button, and an image display.

Refine the gui by aligning the image input and generate button in a horizontal row, applying flex, borders, margins, padding, and resize mode for full-width image.

Explore how to generate images from text using image generation platforms, focusing on Image Nord for text-to-image prompts, adjustable aspect ratios, styles, models, and API usage.

Learn how application programming interfaces enable two programs to communicate by making API calls to external platforms, retrieve weather data, and display results in your app.

Discover how to authenticate with imagine's image generation API, generate API keys, and craft prompt-based requests in JavaScript, Python, or React Native using the playground and API reference.

Build a generate image function in a React Native app and trigger it on button press to fetch prompt from an image generation API using API key header via post.

Learn how to verify an image generation API call in Expo by checking status codes—200 for image bytes, 400 for errors—log the status, and display the generated image on screen.

Extract generated image bytes, convert to base64, and form a data URI to display in a React Native app, using state to show the generated or a default image.

Test the image generation app by wrapping API calls and image conversion in a try-catch, handle errors gracefully, and display generated images from base64 data URI or a default background.

Learn to display icons in React Native apps using Expo vector icons and Material icons, then wrap a send icon in a touchable opacity to trigger image generation.

Improve user experience by showing an activity indicator during image generation in a React Native Expo app, controlled by a loading state that toggles with API calls and resets afterward.

Replace the loading indicator with a Lottie animation in a React Native app during image generation by downloading a JSON, placing it in assets, and enabling autoPlay and looping.

Explore using OpenAI's Dall-E 3 image generation API in your app, including model, prompts, headers, and how responses return image urls or base64 data, plus pricing.

Explore how to call the OpenAI API from a React Native app to generate images with Dall-E 3, handle JSON responses, and save generated images via URL or data URI.
