Rusty Node.js REPL 🦀 🌳 🌀

Documentation.

$ cargo add rusty_nodejs_repl

Usage

Put some JavaScript in a string and pass it to Repl::run. The function will return whatever was sent to stdout:

let mut repl = Config::build()?.start()?;
let result = repl.run("console.log('Hello, world!');").await?;
assert_eq!(result, b"Hello, world!\n");

// Or instead get data from JavaScript via the `output` function along with `Repl::run_tcp`
let result = repl.run_tcp("output('passed through a socket')").await?;
assert_eq!(result, b"passed through a socket");

For more in-depth usage see the test in the Rust Hypercore Replicator.

What?

A way run arbitrary code through Node.js from Rust.

Why?

This is for testing. When working on Node.js related Rust projects it can allow you to co-locate JavaScript along side your Rust.

This crate came from implementing parts of the Hypercore JS ecosystem in Rust. Which requires testing Rust output against JavaScript.
