What are Deep Links, and Why are They Important?
Before we dive into the solution, let’s quickly understand what deep links are and why they’re crucial for your app’s success. Deep links are URLs that point to a specific page or section within your app, allowing users to access specific content or features directly. This enhances the user experience, increases engagement, and drives conversions.
In the context of Expo, deep links are essential for sharing content, promotions, or specific features with users via email. Imagine being able to share a specific in-app offer or a new feature with your users via email, and they can access it directly with a single tap. That’s the power of deep links!
The Issue: Unable to Share Deep Links in Expo App via Email
So, what’s the problem? You’ve set up your Expo app, created deep links, and attempted to share them via email, but they don’t work as expected. You’ve tried various approaches, but the links either don’t open the app or redirect to the wrong page. Frustrating, isn’t it?
The reasons behind this issue can be attributed to several factors, including:
- Incorrect link formatting
- Inproper app configuration
- Email client restrictions
- Platform-specific limitations
Solution 1: Correct Link Formatting
The first step in solving this issue is to ensure your deep links are formatted correctly. Expo uses a specific format for deep links, which includes the following components:
exp://your-app-username/path/to/feature?option1=value1&option2=value2
Here’s a breakdown of each component:
exp://
: The Expo protocolyour-app-username
: Your Expo username or app identifierpath/to/feature
: The path to the specific feature or page within your app: Optional parameters or query strings
Make sure to replace your-app-username
with your actual Expo username and update the path/to/feature
to match the desired app page or feature.
Solution 2: App Configuration and Universal Links
import { Linking } from 'expo';
// Configure Universal Links
Linking.configure({
schemes: ['https', 'exp'],
prefixes: ['exp://your-app-username'],
});
By configuring Universal Links, you’re telling your app to handle links with the exp
scheme and prefix. This ensures that your app will open when a user taps on a deep link, rather than the default browser.
Solution 3: Email Client Restrictions and Workarounds
Email clients, such as Gmail or Outlook, often impose restrictions on links to prevent spamming or phishing attempts. To bypass these restrictions, you can use a link wrapper or a redirect service.
One popular solution is to use a link shortener like Bitly or Rebrandly. These services create a shortened link that redirects to your original deep link. This can help bypass email client restrictions and improve the overall user experience.
Original Deep Link: exp://your-app-username/path/to/feature
Wrapped Link: https://bit.ly/3xYzexample
Solution 4: Platform-Specific Limitations and Workarounds
On Android, you may encounter issues with deep links due to the operating system’s restrictions on custom schemes. To overcome this, you can use the android:scheme
attribute in your `AndroidManifest.xml` file:
<intent-filter>
<action android:name="android.intent.action.VIEW" />
<category android:name="android.intent.category.DEFAULT" />
<category android:name="android.intent.category.BROWSABLE" />
<data android:scheme="exp" />
</intent-filter>
On iOS, you’ll need to configure your `Info.plist` file to handle the exp
scheme:
<key>CFBundleURLTypes</key>
<array>
<dict>
<key>CFBundleURLSchemes</key>
<array>
<string>exp</string>
</array>
</dict>
</array>

Frequently Asked Question
Having trouble sharing deep links in your Expo app via email? You’re not alone! Check out these frequently asked questions to get to the bottom of this pesky issue.
Q1: What is a deep link, and why can’t I share it via email?
A deep link is a URL that directs users to a specific page or section within your app. Unfortunately, Expo apps don’t support sharing deep links via email due to security restrictions. But don’t worry, there are workarounds!
Q2: Can I use the “mailto” protocol to share deep links via email?
Unfortunately, no. The “mailto” protocol only works for plain text emails, not for deep links. You’ll need to explore other options, like using a URL shortener or a third-party sharing service.
Q3: How can I use a URL shortener to share deep links?
Services like Bitly or Rebrandly can help you shorten your deep link into a more manageable URL. Just be aware that some URL shorteners might not support deep linking, so choose wisely!
Q4: Can I use a third-party sharing service to share deep links?
Yes! Services like Branch.io or Firebase Dynamic Links can help you share deep links across different platforms, including email. They often provide more flexibility and customization options than URL shorteners.
Q5: Are there any Expo-specific solutions for sharing deep links?
Yes! Expo provides its own linking mechanism, called Expo Linking. You can use it to generate a link that opens your app or a specific page within your app. It’s a great option if you’re already invested in the Expo ecosystem!
I hope these questions and answers help you overcome the hurdle of sharing deep links in your Expo app via email!
