Expo is a favorite tool for creating mobile applications for many React Native app developers. It streamlines the process by providing pre-configured tools and services that enable you to immediately launch your app.<\/span><\/p>\n

Sometimes, though, you might want to forego Expo and create your React Native <\/span>app from scratch<\/span><\/a>.<\/span><\/p>\n

This article will assist you through the process whether you need greater control over native modules, want to maximize performance, or just want to stay away from some of Expo’s constraints.\u00a0<\/span><\/p>\n

<\/span>Why Build a React Native App Without Expo?<\/span><\/span><\/h2>\n

While Expo provides a streamlined environment for React Native development, it also abstracts a lot of the underlying configurations. This can be both a blessing and a curse. By not using Expo, you gain several advantages:<\/span><\/p>\n

<\/span>Full Control Over Native Modules<\/span><\/span><\/h3>\n

Expo simplifies many tasks, but it also limits your ability to access and modify native code directly. For instance, if you want to integrate custom native modules or third-party libraries that require native code modifications, using Expo can be restrictive. Building without Expo allows you to have full control over native modules, enabling you to add features that may not be supported by Expo.<\/span><\/p>\n

<\/span>Better Performance<\/span><\/span><\/h3>\n

For large-scale applications, the overhead introduced by Expo can sometimes lead to performance bottlenecks. Expo apps tend to include a lot of pre-configured features that, while useful, may not be necessary for your specific app. By bypassing Expo, you can strip down your app to only include the features you need, resulting in faster load times and more efficient resource management.<\/span><\/p>\n

<\/span>No Dependency on Expo SDK Versions<\/span><\/span><\/h3>\n

Expo regularly updates its SDK, and while this ensures that you have access to the latest features, it can also be a limitation. If you need to use a version of React Native that is not yet supported by the latest Expo SDK, you\u2019re stuck waiting for Expo to catch up. By building your app without Expo, you have the freedom to update React Native and other dependencies as soon as new versions are released.<\/span><\/p>\n

<\/span>Setting Up the Development Environment<\/span><\/span><\/h2>\n

Before you start building your React Native app without Expo, it’s essential to have the right development environment set up. Here\u2019s a detailed guide to getting your environment ready:<\/span><\/p>\n

<\/span>Step 1: Install Node.js and npm\/yarn<\/span><\/span><\/h3>\n

React Native relies on Node.js, a JavaScript runtime built on Chrome’s V8 JavaScript engine. npm (Node Package Manager) or yarn will help you manage your project’s dependencies. To install Node.js, visit the<\/span> official Node.js website<\/span><\/a> and download the latest stable version.<\/span><\/p>\n

Once Node.js is installed, npm will be installed automatically. If you prefer using yarn, you can install it globally using npm:<\/span><\/p>\n

npm install -g yarn<\/b><\/p>\n

<\/span>Step 2: Install React Native CLI<\/span><\/span><\/h3>\n

The React Native CLI is a command-line tool that enables you to initialize and manage React Native projects without relying on Expo. You can install it globally using npm or yarn:<\/span><\/p>\n

npm install -g react-native-cli<\/b><\/p>\n

This CLI will be your primary tool for creating new projects, running your app, and managing other development tasks.<\/span><\/p>\n

<\/span>Step 3: Install Java Development Kit (JDK)<\/span><\/span><\/h3>\n

If you’re developing for Android, you\u2019ll need to install the Java Development Kit (JDK). The JDK provides the necessary tools for compiling and running Java code, which is essential for Android development.\u00a0<\/span><\/p>\n

After installation, ensure that the JDK is properly set up by adding it to your system’s PATH environment variable. This allows your system to recognize Java commands from the terminal.<\/span><\/p>\n

<\/span>Step 4: Set Up Android Studio<\/span><\/span><\/h3>\n

Android Studio is the official Integrated Development Environment (IDE) for Android development. It includes the Android SDK, which provides the necessary tools to build, test, and debug Android apps. Download and install Android Studio from the<\/span> official website<\/span><\/a>.<\/span><\/p>\n

After installation, open Android Studio and follow the setup wizard to install the necessary components, including the Android SDK, Android Virtual Device (AVD), and any additional tools required for your development needs.<\/span><\/p>\n

You will also need to set up the Android SDK location in your system environment variables:<\/span><\/p>\n

You can download the JDK from the<\/span> Oracle website<\/span><\/a> or use an open-source alternative like OpenJDK.<\/span><\/p>\n
