Building a Lightweight Biometric Authentication Library for React Native with Kotlin
Hello developers! Today, I want to share a quick story about a common challenge I faced while working with React Native: securing app access with biometric authentication, and why I decided to build and open-source my own library: @vijeshkr/react-native-biometric-auth The Spark: Why Another Biometric Library? While working on a mobile application that required secure user authentication, such as…
In the world of mobile app development, ensuring secure user authentication is a crucial task. When faced with the challenge of biometric authentication in a React Native app, the author decided to create their own lightweight library to address existing limitations. The result is @vijeshkr/react-native-biometric-auth, a Kotlin-based Android biometric authentication library for React Native.
This library offers several key features, including a Kotlin native module, AndroidX Biometric APIs, device credential fallback, promise-based authentication, TypeScript support, and simple React Native integration. By leveraging modern Android biometric APIs and the Kotlin programming language, the author aimed to build a lightweight, easy-to-use solution that provides a better developer experience compared to existing options.
