![]() If you adjust the manifest, you’ll need to uninstall and reinstall the app in order for iOS to fetch it again, otherwise it’ll cache for 24 hours. In Safari, when open on a page that has Universal Links enabled, we can swipe down to expose this bar: Instead, we run our app on our iOS device, open safari and navigate to our URL. To test Universal Links on iOS, we can’t use the simulator (as far as I know, I couldn’t get it to work). Start your app from X Code, go into the Contacts app and add a URL for one of the fake contacts so it looks like this: On iOS, I find it’s easier to test on the simulator. If everything was configured properly, our app will open, regardless of whether it was running or not! Replacing the custom URL scheme and package name with your respective values. We can boot up our emulator or device, and send a deeplink intent directly to the app from the command line: adb shell am start -a -d "ionichats://app/hats/very-nice-hat" io.ionic.hats Testing DeeplinksĪssuming we have everything set up correctly (or at least we think we do), it’s time to start testing Deeplinks. You may also need to enable the entitlement from the Developer center for your app. However, for iOS, you’ll then enable the domain in the Associated Domains section of your entitlements, with the form applinks:: You’ll publish a specific json file for iOS and one for Android, ensure your site is using HTTPS, and then configure your app to open in response to links to that domain.įor Android, it pretty much Just Works from the plugin install above. This process is primarily done on the server side of your website. To configure iOS and Android, we need to enable Universal Links for iOS, and App Links for Android (6.0+). Configuring Universal Links (iOS) and App Links (Android) We’re almost ready to handle deeplinks, we just need to configure Universal Links on iOS and App Links on Android 6.0 so our app can open when navigating to. In the install command, we provide the custom URL scheme we want to handle ( ionichats), the host domain we will respond to ( ) and the host protocol we will listen for, which 99% of the time will be https as it’s required on iOS and Android. The Ionic Deeplinks plugin requires some variables in order to get set up properly: cordova plugin add ionic-plugin-deeplinks -variable URL_SCHEME=ionichats -variable DEEPLINK_SCHEME=https -variable DEEPLINK_HOST= Now that we have our URL scheme, website, and deeplinking path decided, let’s install the Deeplinks Plugin: Installing Ionic Deeplinks Additionally, let’s say we want to enable a custom URL scheme of the form ionichats://app/hats/very-nice-hat. We can actually launch our app when someone navigates to this URL on Android or iOS and display the app version of the Hat product page. A URL to one of those Hats might look like. Let’s say we run a Hat Shop and we have a website version of our store where we display our many fancy Hats. The first thing we need to do is figure out what kind of deeplink we want our app to respond to. Let’s take a look at how it works: Choosing a Deeplink To help Ionic developers deeplink more easily, we are excited to announce a new, official way to deeplink into both Ionic 1 and Ionic 2 apps (and non-ionic Cordova apps): the Ionic Deeplinks Plugin along with Ionic Native 1.3.0. Each evolution in the deeplinking feature set has caused churn in both what mobile devices support and what they no longer support, making it a tall order to keep up. Additionally, OS’s now support powerful ways to index and search data inside of native apps. Native apps are only just catching up, and so it hasn’t always been obvious how to link into an app the way we link into a webpage.ĭeeplinking as a concept has evolved heavily over the last few years, with mobile devices going from supporting custom URL schemes (like instagram://) to now opening native apps in response to navigation to URLs (like ). ![]() As web developers we live and breathe deep-linking because that was the major innovation of the web. I was doing some research on common challenges developers face while building their Ionic apps, and one of the things that kept coming up was Deeplinking.įor those not familiar, Deeplinking makes it possible to direct a user to content hidden deep in a native app, whether that’s from another app or a web browser. We’ve since released a Capacitor guide covering how to implement Universal Links (iOS) and App Links (Android) – available here.
