This library provides a simple and effective solution for generating standardized User-Agent strings in React Native applications. It automatically assembles a User-Agent string with predefined components such as application name, version, device name, and network information.

Key Features

• Predefined User-Agent Format: Automatically generates User-Agent strings with a fixed format.
• Cross-Platform Support: Compatible with both iOS and Android platforms.
• Simple Integration: Easy-to-use API for quick setup in your React Native projects.

Install the library via npm or yarn.

Import and use the provided method to obtain the User-Agent string.

npm install @mobeuv/react-native-user-agent
yarn add @mobeuv/react-native-user-agent

Usage

import { getUserAgent } from '@mobeuv/react-native-user-agent';

const fetchUserAgent = async () => {
  try {
    const userAgent = await getUserAgent();
    console.log(userAgent);
    // iOS Result =
    // Android Result =
  } catch (error) {
    console.error('Error fetching User-Agent:', error);
  }
};

Pattern

Platform	Pattern	Example
iOS	APPLICATION_NAME/APPLICATION_VERSION_NAME - Darwin/DARWIN_VERSION CFNetwork/CFNETWORK DEVICE_NAME SYSTEM_NAME/SYSTEM_VERSION	ReactTestApp/1.0 - Darwin/23F79 CFNetwork/1474 iPhone iOS/17.0
Android	APPLICATION_NAME/APPLICATION_VERSION_NAME - WebSettings_getDefaultUserAgent	ReactNativeUserAgentExample/1.0 - Mozilla/5.0 (Linux; Android 12; sdk_gphone64_arm64 Build/SE1A.220203.002.A1; wv) AppleWebKit/537.36 (KHTML, like Gecko) Version/4.0 Chrome/124.0.6367.179 Mobile Safari/537.36

If WebSettings.getDefaultUserAgent is unavailable or an error occurs, we will try using System.getProperty("http.agent"). If getProperty also fails, the User-Agent will default to APPLICATION_NAME/APPLICATION_VERSION_NAME. In case of any generic errors, a rejection will be handled through a catch block.

Requirements

• Kotlin Version: >= 1.7.0
• Android MinSdkVersion: >= 21
• Android NDK Version: >= 21.4.7075529

Handling Errors

If an error occurs during the construction of the User-Agent, a rejection will be thrown in the promise. Always remember to handle this and, if necessary, set your own temporary User-Agent.

Need a custom User-Agent? Create a PR adding this method for Kotlin and Swift. Just make sure that the methods used do not require a privacy manifest; if they do, you'll need to add the privacy manifest in the PR.
