Abstract
This paper explores the potential of optimizing node.js applications by integrating rust. In particular, in processing cpu-intensive tasks where javascript faces performance limitations due to its single-threaded architecture. Rust's memory safety and parallelism model, which eliminates the need for a garbage collector, makes it an attractive alternative to traditional c/c++ modules for extending the capabilities of node.js. This study explores the performance gains achieved by integrating rust, both through native bindings and WebAssembly, demonstrating significant improvements in computational efficiency, especially in parallel processing scenarios. Rust's ability to efficiently handle computation-intensive workloads with work interception algorithms is emphasized as a key factor in overcoming javascript bottlenecks. The study includes a detailed performance evaluation that compares synchronous and asynchronous modules in node.js with rust implementations. Tests demonstrate how rust optimizations outperform javascript by up to ten times in certain computational tasks. The study also evaluates cross-compiled rust modules using WebAssembly in the browser environment, which once again illustrates the advantages of rust in providing near-native performance. The results emphasize the potential of rust to enhance node.js applications by making them more scalable, reliable, and efficient for high-performance web applications
