Varun Dhananjaya - Developer at Comm - How To Integrate Rust Into A React Native App
Varun from Comm Technologies shares insights about using multiple languages in their encrypted messaging app and explores the need for Rust in their tech stack. He discusses the pros and cons of using C++ in their React Native app, highlighting challenges like callback complexity, library integration pains, and lack of memory safety.
He elaborates on how Rust addresses these challenges by leveraging async await syntax, efficient dependency management with Cargo, and the strong memory safety features that Rust offers. Varun also demonstrates how to call Rust from C++ and integrate it into a React Native app using JSI, showcasing a live coding demo.
