node-with-rust

A short example using fibonacci calculation to compare Node.js vanilla js execution vs Node.js calling Rust compiled function.

Installation

You will need Node.js and rust compiler installed!

1. cd node-with-rust
2. cargo build --release Compile the dynamic library
3. npm install Install npm dependencies
4. npm run compare run comparison of the fibonacci functions

Rust code can be found in src/lib.rs Node code to load the dynamic library and the vanilla implementation of fibonacci is in lib/index.js the comparison test can be found in ./compare.js

By default the 45th number in the fibonacci sequence is calculated:
