PSPDFKit, a tool for integrating document functionality in apps, has developed a native plugin for the Ionic platform to provide PDF capabilities using their iOS and Android SDKs. Initially created for Cordova, the plugin is now compatible with Capacitor, allowing developers to integrate PDF viewing, annotating, and editing features into their applications with a unified JavaScript API that works seamlessly across both iOS and Android platforms. The plugin emphasizes the importance of a cross-platform approach, ensuring minimal differences in API behavior between platforms to reduce maintenance costs and enhance usability for developers building multi-platform apps. PSPDFKit's solution leverages native platform SDKs to deliver optimized performance while offering customization options like page transitions and background color changes, and it supports programmatic interactions such as page switching. This integration highlights PSPDFKit's commitment to providing robust document management tools, enhancing the functionality of apps with minimal complexity.
