Boosting Performance: Rewriting a Node.js Module into Rust
The article discusses the process of rewriting a Node.js module into Rust and the significant performance boost achieved. The author shares their experience of replacing an internal Node.js module with a native Rust module, resulting in a 25x performance improvement. The module in question is a part of a platform called CDN Stats, which displays and aggregates data and statistics derived from Wix's CDN. The author explains the process of populating a data table by sifting through CDN logs and parsing them into meaningful information. They highlight the challenges faced in handling large amounts of data and the initial attempts using the Wix Serverless framework. Ultimately, the decision to rewrite the module in Rust using napi.rs proved to be successful. The article provides insights into the benefits of using Rust for performance-critical tasks and showcases the potential of leveraging native modules for optimizing Node.js applications.
