In a lively chat, Marc Rousavy, an Austrian full-stack developer and CEO of Margello, dives into the world of Nitro Modules, a groundbreaking tool designed to elevate React Native's performance. He explains how its object-oriented design simplifies native module creation and compares it to Turbo and Expo Modules. The conversation also ventures into the integration of C++ with React Native using TypeScript, while humorously acknowledging community contributions with a potato pun. Insights on Swift and Kotlin integration add to the wealth of knowledge shared!
Nitro Modules significantly enhance React Native by enabling efficient handling of complex native types with improved performance metrics compared to Turbo and Expo Modules.
The transition to Nitro for library authors is simplified through a code generator called Nitrogen, promoting an easier development experience and better inter-component interactions.
Deep dives
Introduction to Nitro Modules
Nitro Modules, developed by Mark Rusavi, enables the creation of high-performance C++, Swift, or Kotlin modules bridged to JavaScript. This approach addresses limitations associated with existing Turbo Modules and Expo Modules, particularly in handling complex C++ or Swift types via a bridge, which Turbo and Expo fail to accommodate effectively. Nitro allows developers to expose intricate native types to JavaScript, facilitating the efficient handling of large data, such as image frames in real-time processing applications. As a result, this framework enhances both the flexibility and maintainability of native modules in React Native apps.
Performance Advantages of Nitro
The performance gains offered by Nitro Modules are substantial, with benchmarks indicating that it can be up to 59 times faster than Expo Modules and 15 times faster than Turbo Modules when executing operations. Specifically, a test designed to assess the speed of function calls showed that Nitro completed tasks in just 7.3 milliseconds, a significant reduction compared to its counterparts. This remarkable efficiency stems from Nitro's design, which eliminates the need for lengthy manual JavaScript interface (JSI) bindings and allows better in-memory data handling. As Nitro becomes integrated into existing libraries, app developers can expect improved performance benefits automatically without extensive changes to their own codebases.
Library Developer Experience with Nitro
For library authors, transitioning to Nitro involves a relatively straightforward process aimed at enhancing the developer experience. The use of a code generator called Nitrogen allows for the automatic generation of C++ bindings from TypeScript, streamlining the development of native modules. Developers will benefit from the object-oriented design structure in Nitro, which supports hybrid objects and eliminates cumbersome data copying, enabling smoother inter-component interactions. As Nitro modules gain traction, the React Native community can anticipate a boost in library performance and usability.
