In this guide from 2016, the Ionic team discusses the challenges and solutions related to implementing deeplinking in Ionic apps, which allows users to navigate directly to specific content within a native app from external sources like web browsers. The text explains how deeplinking has evolved from custom URL schemes to more integrated systems like Universal Links for iOS and App Links for Android, and how these advancements have influenced mobile device support and development practices. The Ionic Deeplinks Plugin, introduced to simplify the process for developers, allows Ionic 1 and Ionic 2 apps (and non-Ionic Cordova apps) to handle deeplinks effectively. The guide details the setup process, including configuring Universal and App Links, testing deeplinks on Android and iOS, and responding to deeplinks using Ionic Native, which integrates with various Cordova plugins to support modern web development practices. It emphasizes that while routing and deeplinking are related, they serve different functions, with deeplinking focusing on launching apps from external sources. The article concludes by inviting feedback to improve the feature's implementation in Ionic apps.
