Discover the transformative power of Expo Application Services (EAS) in the world of mobile app development. EAS is a suite of cloud-based services offered by Expo that revolutionizes the way developers build and deploy applications across Android and iOS platforms.
In this module, we delve into the core components of EAS: Build, Submit, and Update. EAS Build provides a cloud-based environment that eliminates the need for a local build setup using heavy software like Xcode or Android Studio. This service simplifies the process of creating robust builds for your apps without the usual frictions associated with local environments. EAS Submit automates the tedious process of app store submissions, allowing developers to push their applications directly to the Play Store and App Store with ease. Lastly, EAS Update introduces the concept of over-the-air (OTA) updates, enabling developers to deploy updates without requiring users to download a new version from the app store.
The video also contrasts EAS with Expo Go, highlighting the limitations of the latter. Expo Go acts as a sandbox for quick prototyping but lacks support for custom native code, advanced APIs, and is tied to specific SDK versions. In contrast, a development build with EAS allows for extensive customization, use of third-party SDKs, and testing of full app features, providing a true performance measure.
By the end of this session, you'll understand how EAS can streamline your app development and deployment processes, making it an indispensable tool for modern developers.

The host demonstrates starting a development server using Expo Go, while addressing its limitations and moving towards configuring your project with necessary tools.
The tutorial walks you through installing the ES CLI tool and logging into your account using the ESLogin command. It highlights the importance of configuring your project specifically for Android, avoiding the complexities of iOS security settings for now. As you proceed, you'll see how to run the 'es build:configure' command, create an ES project, and access your project dashboard. The video concludes with instructions on setting up a development build using the Expo Dev Client, ensuring your application is ready for debugging and internal distribution.
By the end of this tutorial, you'll be equipped with the knowledge to configure a development build for your Expo app, paving the way for efficient testing and deployment.
Creating a cloud build for your Android application has never been easier, thanks to EAS Build. In this detailed tutorial, you'll learn how to generate a development build that runs seamlessly on Android devices. The process begins with understanding the importance of using an APK format for Android development, as this is the only compatible option for installation.
The guide delves into the specifics of configuring your ESJSON file, ensuring the 'development client' is set to true. This crucial step allows you to create a dot APK instead of the AAB format, which is intended for Google Play Store distribution but not suitable for device installation. Following this, you'll be guided through the command-line process. You'll learn how to run the 'EAS build' command with the appropriate platform and profile settings, specifying your Android application ID.
As the build process progresses, you'll observe the generation of a new key store, the compression of your project, and its subsequent upload to EAS Build. The tutorial provides a comprehensive look at the build environment setup, including reading ESJSON and package JSON files, installing dependencies, and eventually running the build on an emulator. You'll also discover how to install the APK using a QR code for quick access.
By the end of this tutorial, you'll be well-equipped to create and deploy Android development builds using EAS Build, paving the way for efficient app testing and eventual deployment to the Play Store.
Creating multiple app variants can significantly streamline your development process by allowing tailored builds for different environments such as development, preview, and production. The process begins by assigning unique identifiers to each variant; for Android, this means a distinct application ID, while iOS requires a unique bundle identifier. This ensures each variant operates independently, minimizing potential conflicts.
The transformation starts by renaming your configuration file from `app.json` to `app.config.ts`, enabling the use of TypeScript for added type safety. The configuration involves exporting default values and enclosing them within parentheses, a necessary step for organizing and managing configurations effectively. Importing types from Expo's config further solidifies the structure, ensuring that your app's configuration aligns with TypeScript standards.
Next, dynamic values based on the environment are set up. By utilizing `process.env` variables such as `isDev` and `is_preview`, you can dynamically alter identifiers based on the current build environment. This flexibility is crucial for maintaining distinct versions of your application across different stages of development. Moreover, adding these configurations to the EAS JSON file allows seamless integration with Expo's build system, enabling you to build and test various app variants efficiently.
After watching, you'll be equipped to manage app variants with ease, ensuring each build is perfectly tailored to its intended environment for optimal performance and testing.
Become a job-ready mobile developer by building real apps with React Native and Expo | from your very first component to authentication, maps, and production builds.
Mobile is where users spend most of their time, yet skilled mobile developers are still in short supply. This course closes that gap. If you already know a little JavaScript and React, you'll learn how to turn that knowledge into real, installable Android and iOS apps using Expo - the modern, beginner-friendly framework built on top of React Native and trusted in production by apps like Instagram and Discord.
We start from the ground up: what mobile development is, how React Native compares to Expo, and how to set up your environment and ship your first project. From there you'll master the core components (View, Text, Image, TextInput, Pressable, StyleSheet), styling, props, and list rendering - then put them to work building real screens.
Next, you'll go deep into navigation - first with React Navigation, then with modern Expo Router file-based routing, including dynamic routes, catch-all segments, layouts, route groups, stacks, tabs, drawers, and modals. You'll learn how to talk to APIs (both your own Expo API routes and external services), and how to persist data using AsyncStorage, SecureStore, SQLite, and the file system.
The second half is all about going native. You'll work with device sensors (accelerometer, gyroscope, magnetometer, light sensor, pedometer), the camera and microphone, network, deep linking, haptics, and battery APIs, interactive maps with markers and polylines, and push notifications. You'll then implement complete authentication flows — protected routes, email/password login, Google and GitHub OAuth, and third-party providers like Better Auth and Clerk — and learn EAS development builds and app variants to get your app onto real devices.
To tie it all together, you'll build real-world capstone projects, including a Weather app (Expo Location, live weather/forecast/AQI APIs, custom hooks, and dynamic backgrounds), a Pinterest-style Pixabay wallpaper app (search, color & category filters, detail modals, and image downloads), and a standout AI Story Generator that uses the AI SDK and OpenRouter to generate stories and images from a single prompt — routing requests to models like OpenAI, Gemini, and Claude with structured, Zod-validated output, plus local storage and dark mode.
Throughout the course you'll also cement every concept with hands-on mini-projects, including a Profile Card Gallery, a Pokédex app, a Notes Buddy storage app, a News Feed reader, a Tilt-the-Ball sensor game, a Profile Pic Creator, and a Reminder Buddy notifications app.
By the end, you won't just understand Expo — you'll have built a portfolio of real apps (including an AI-powered one) and the confidence to design, build, and ship your own mobile products. Enroll now and start building.
