Deep Links and Universal Links in React Native

In the dynamic field of mobile app development, ensuring a fluid and uninterrupted navigation experience holds immense importance. Deep links and universal links emerge as robust instruments, facilitating direct access to distinct content within your React Native application from external origins such as websites, emails, or other applications. In the following article, we will delve into the intricacies of deep links and universal links, highlighting their advantages, and demonstrating their integration into a React Native app through tangible code illustrations.

Understanding Deep Links and Universal Links

Deep Links are URLs designed to direct users to particular content or resources within a mobile app. When a user interacts with a deep link, it initiates the app and guides the user seamlessly to the linked content. This technique is frequently employed to simplify user pathways and enhance the overall user experience, effectively minimizing the necessary steps for users to access pertinent information.

Universal Links, on the contrary, universal links represent a distinct application of deep links on iOS gadgets. Universal links harmoniously interact with the iOS system, enabling the application to manage the link without necessitating a confirmation dialog. This results in a more cohesive and smooth user experience in comparison to conventional deep links.

Benefits of Deep Links and Universal Links

1. Enhanced User Experience: Deep links and universal links facilitate a more seamless and intuitive transition between external sources and your application, resulting in enhanced navigation experiences for users.
2. Improved Conversion Rates: Enabling direct access to pertinent content can effectively enhance engagement and boost conversion rates, given that users are more inclined to carry out actions within the application.
3. Easy Content Sharing:With great ease, users have the capability to effortlessly distribute deep links, enabling the seamless sharing of articles, products, or various other items with their friends and colleagues.

Implementing Deep Links and Universal Links in React Native

1. Deep Links

To implement deep links in your React Native app, follow these steps:

1. Register a URL scheme in your app’s Info.plist (iOS) and AndroidManifest.xml (Android) files.
2. Handle the deep link navigation in your app’s entry file by listening to the Linking event and using the getInitialURL function.

import { Linking } from 'react-native';

Linking.getInitialURL().then(url => {
  if (url) {
    // Parse the URL and navigate to the corresponding screen
  }
});

Linking.addEventListener('url', ({ url }) => {
  // Handle the URL and navigate to the appropriate screen
});

2. Universal Links

For iOS, universal links offer a more integrated experience:

1. Configure the associated domains in your app’s Entitlements file and website’s apple-app-site-association file.
2. Handle universal link navigation using the Linking event as shown above.

Code Example

Let’s consider an example where our React Native app displays articles, and we want to implement deep links to directly open specific articles. Here’s how you can achieve this:

import React, { useEffect } from 'react';
import { Linking } from 'react-native';

const ArticleScreen = ({ route }) => {
  const { articleId } = route.params;

  useEffect(() => {
    // Fetch and display the article based on the articleId
  }, []);

  return (
    // Render the article content
  );
};

export default ArticleScreen;

Linking.getInitialURL().then(url => {
  if (url) {
    const articleId = // Extract articleId from the URL
    // Navigate to the ArticleScreen with the extracted articleId
  }
});

Linking.addEventListener('url', ({ url }) => {
  const articleId = // Extract articleId from the URL
  // Navigate to the ArticleScreen with the extracted articleId
});

Conclusion

Utilizing deep links and universal links offers a streamlined method to seamlessly incorporate your React Native application with external sources. By applying these navigation methods, you can provide users with a smooth and hassle-free encounter, ultimately leading to increased engagement and improved user contentment. Harnessing the capabilities of deep links and universal links allows you to elevate the navigation of your React Native app to an advanced level.
