Are you looking to serve static assets in your React Native application? With the help of the React Native Static Server, you can easily set up an embedded HTTP server for Android, iOS, Mac (Catalyst), and Windows platforms. This guide will walk you through the steps, ensuring a smooth setup experience.

1. Getting Started with the Installation

Before diving into the implementation, let’s get our environment ready. Here’s how to install the package:

npx install-peerdeps @dr.pogodin/react-native-static-server

Make sure your development environment meets the prerequisites for the platform you are targeting. If you’re building for Android, check your Android SDK version, as versions 28 and above forbid cleartext HTTP by default.

2. Create a Server Instance

This is where the magic begins. Creating a server instance can be likened to setting up a reception in a hotel. You need to define where your guests (data requests) come from and where you’ll send them (responses).

import Server from '@dr.pogodin/react-native-static-server';
const server = new Server({
  fileDir: 'path/to/static/assets/on/device',
});

In this scenario, fileDir is the path to your static assets just like where you’d store the registration forms at a hotel reception.

3. Starting and Stopping the Server

To handle requests, your server must be turned on. This involves starting the server, allowing it to listen for incoming requests. Once the server is done, you will want to shut it down gracefully.

(async () => {
  const origin = await server.start();
  console.log(`Server is up at: ${origin}`);
})();

Stopping the server can be done with a simple call:

server.stop();

4. Bundling Assets for the App

Just as a hotel prepares rooms ahead of time, you’ll want to bundle your assets during app build time. This allows you to access them seamlessly at runtime. Ensure in your build.gradle that you specify the folders containing your assets:

android {
  sourceSets {
    main {
      assets.srcDirs = ['path/to/assets']
    }
  }
}

On other platforms, you may need to manage your assets through Xcode and include them in your project folder.

5. Working with Modules

To utilize advanced functionalities like aliasing or rewriting URLs, configure additional modules. Think of these as special services offered at a hotel to ensure guests have a better experience.

const server = new Server({
  extraConfig: `
    server.modules += (mod_alias)
    alias.url = ("/special" = "/path/to/special/asset")
  `
});

Troubleshooting Tips

Even with detailed instructions, you might run into issues. Here are some troubleshooting tips that can help:

• Server Won’t Start: Ensure that no other server instance is running. You can only have one active server at a time.
• Assets Not Found: Double-check paths in your configuration. Ensure assets are bundled properly.
• Cleartext Not Permitted: For Android, add android:usesCleartextTraffic="true" in your AndroidManifest.xml file.
• Log Errors: Set up error logging in the server configuration to get more insights on what may have gone wrong.
