Unlocking the Power of Deep Links and Web Credentials on Your Ionic Capacitor App

As a developer, you’re always looking for ways to take your app to the next level. That’s where deep links and web credentials come in – two powerful features that can elevate the user experience and security of your Ionic Capacitor app. In this article, we’ll dive into the world of deep links and web credentials, and show you how to implement them seamlessly into your project.

What are Deep Links?

Deep links are a type of URL that skips the login process and takes users directly to a specific page or feature within your app. Instead of launching the app’s homepage, a deep link can redirect users to a specific section, such as a product page, a user profile, or a settings menu.

For example, let’s say you have an e-commerce app that sells shoes. A deep link could be used to direct users to a specific product page, such as https://myapp.com/shoes/nike-airforce-1, instead of launching the app’s homepage.

Benefits of Deep Links

• Improved user experience: Deep links reduce the number of steps users need to take to access a specific feature or page, making it easier for them to get what they need.
• Increased conversions: By directing users to a specific page, you can increase the chances of them completing a desired action, such as making a purchase.
• Better analytics: Deep links provide valuable insights into user behavior and preferences, helping you refine your marketing strategies and improve your app’s overall performance.

Implementing Deep Links on Your Ionic Capacitor App

Now that we’ve covered the benefits of deep links, let’s get started on implementing them on your Ionic Capacitor app. Follow these steps to add deep linking to your project:

1. Step 1: Configure Your App’s URL Scheme

   In your Capacitor project, you need to configure your app’s URL scheme to handle deep links. To do this, add the following code to your capacitor.config.js file:

         {
           "plugins": [...],
           "urlScheme": "myapp"
         }
       

   Replace “myapp” with your app’s custom URL scheme.

2. Step 2: Add a Deep Link Handler

   Next, you need to add a deep link handler to your app. Create a new file called deep-link-handler.ts and add the following code:

         import { Plugins } from '@capacitor/core';
   
         export class DeepLinkHandler {
           constructor(private router: any) {}
   
           handleDeepLink(url: string) {
             const route = url.replace('myapp://', '');
             this.router.navigateByUrl(route);
           }
         }
       

   This code creates a deep link handler that extracts the route from the URL and navigates to it using the Angular router.

3. Step 3: Integrate the Deep Link Handler with Your App

   Now, integrate the deep link handler with your app by adding it to your app’s module:

         import { NgModule } from '@angular/core';
         import { RouterModule } from '@angular/router';
         import { DeepLinkHandler } from './deep-link-handler';
   
         @NgModule({
           declarations: [AppComponent],
           entryComponents: [],
           imports: [
             RouterModule.forRoot([
               {
                 path: '**',
                 component: AppComponent
               }
             ])
           ],
           providers: [DeepLinkHandler],
           bootstrap: [AppComponent]
         })
         export class AppModule {}
       

   This code adds the deep link handler as a provider to your app module.

What are Web Credentials?

Web credentials are a secure way to store and retrieve login credentials on a user’s device. By using web credentials, you can provide a seamless login experience for your users, eliminating the need for them to remember multiple usernames and passwords.

In an Ionic Capacitor app, web credentials are stored using the WebCredentialManager plugin. This plugin provides a secure way to store and retrieve credentials, ensuring that sensitive information is protected.

Benefits of Web Credentials

• Improved user experience: Web credentials simplify the login process, reducing friction and making it easier for users to access your app.
• Enhanced security: By storing credentials securely on the device, you can reduce the risk of password theft and phishing attacks.
• Increased conversions: With a seamless login experience, users are more likely to complete desired actions, such as making a purchase or accessing premium content.

Implementing Web Credentials on Your Ionic Capacitor App

Now that we’ve covered the benefits of web credentials, let’s get started on implementing them on your Ionic Capacitor app. Follow these steps to add web credentials to your project:

1. Step 1: Install the WebCredentialManager Plugin

   In your Capacitor project, install the plugin using the following command:

         npm install @capacitor/web-credential-manager
       

   This plugin provides a secure way to store and retrieve web credentials.

2. Step 2: Configure the WebCredentialManager Plugin

   Next, configure the WebCredentialManager plugin by adding the following code to your capacitor.config.js file:

         {
           "plugins": [
             {
               "name": "WebCredentialManager",
               "ios": {
                 "WebCredentialManager": "com.getcapacitor.WebCredentialManager"
               }
             }
           ]
         }
       

   This code configures the WebCredentialManager plugin for your app.

3. Step 3: Store Web Credentials

   Now, store web credentials using the WebCredentialManager plugin. Create a new file called login.ts and add the following code:

         import { WebCredentialManager } from '@capacitor/web-credential-manager';
   
         export class LoginComponent {
           constructor(private webCredentialManager: WebCredentialManager) {}
   
           login(username: string, password: string) {
             this.webCredentialManager.storeCredential({
               username,
               password
             }).then(() => {
               console.log('Credentials stored successfully!');
             }).catch((error) => {
               console.error('Error storing credentials:', error);
             });
           }
         }
       

   This code uses the WebCredentialManager plugin to store the user’s login credentials securely on the device.

4. Step 4: Retrieve Web Credentials

   Finally, retrieve the stored web credentials using the WebCredentialManager plugin. Add the following code to your login.ts file:

         retrieveCredentials() {
           this.webCredentialManager.getCredential().then((credential) => {
             if (credential) {
               console.log('Retrieved credentials:', credential);
               // Use the retrieved credentials to log in the user
             } else {
               console.log('No credentials found!');
             }
           }).catch((error) => {
             console.error('Error retrieving credentials:', error);
           });
         }
       

   This code retrieves the stored web credentials and uses them to log in the user.
