Rusty Node.js REPL

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 where there is a need to test a Rust implementation against the JavaScript implementation.

Usage

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

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

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