Comparing the efficiency of EAS CLI and local builds for React Native apps, highlighting Expo CLI's advantages in simplifying development.

Simplified React Native development
Expo greatly simplifies the process of building .apk and .ipa files for us, whether it's done locally or through their EAS cloud service.
Expo CLI streamlines the development, building, and deployment of React Native applications through a command-line interface. Offering a suite of tools and services, it abstracts much of the intricacy of native app development, enabling developers to concentrate on coding. By harnessing Expo CLI, developers can efficiently create, test, and deploy their applications, bypassing the complexities of native app development.
In a conventional React Native application, developers are tasked with managing native code and dependencies. However, Expo CLI simplifies this by abstracting these complexities. This allows developers to concentrate on writing JavaScript code while Expo takes care of the native code. As a result, setting up and maintaining a React Native project becomes significantly less time-consuming and effort-intensive.
1. Moving from Expo's Managed Workflow to Bare Workflow
android
and iOS
directories in your project, containing the native code.
Using Android Studio:
1. Open the android folder in Android Studio.
2. Wait for the Gradle sync to finish.
3. There needs to be a directory labeled "Gradle Scripts" situated beneath all other directories.
a. Open the file called as build.gradle (Module :app) inside the Gradle Scripts
4. Go to Build > Generate Singled Bundled or APK
5. After the build completes, you can find the APK in the android/app/release/app-release.apk folder.
First, you need to install the EAS CLI globally on your machine. Open your terminal and run:
Before you can use EAS Build, you need to log in to your Expo account. Run the following command and follow the prompts:
Navigate to your Expo project directory and run:
This command will guide you through the process of setting up EAS Build for your project. It will ask you to choose the platforms you want to build for (Android and/or iOS) and configure your project accordingly.
It will also create an eas.json file in the root directory with the default configuration. It looks something like this
Now, you're ready to build your app. To build an APK for Android, run:
To build an IPA for iOS, run:
You can also build both platforms at once by omitting the --platform flag:
Once the build process is complete, EAS CLI will provide you with a URL to download your APK or IPA file. You can download the file directly from your browser or use the provided URL in your terminal.
Expo CLI offers a powerful and efficient way to develop, build, and deploy React Native applications. It simplifies the development process by abstracting away the complexities of native code management. However, for scenarios requiring custom native code or when you need full control over the build process, ejecting the project and generating local builds provides the necessary flexibility. By understanding the differences between cloud Expo builds and local builds, we can choose the most appropriate build strategy for their specific needs, whether it's for testing, distribution, or custom native code integration.
