test(js) Check the types and lightly the data, but not that much.
Because NodeJS can have different i18n behaviors depending of the
version, let's keep things simple. In this case, we want to test the
types,

wasm-bindgen

Facilitating high-level interactions between wasm modules and JavaScript.

Introduction blog post: "JavaScript to Rust and Back Again: A wasm-bindgen Tale"

Build Status Build status API Documentation on docs.rs

Import JavaScript things into Rust and export Rust things to JavaScript.

src/lib.rs:

#![feature(proc_macro, wasm_custom_section, wasm_import_module)]

extern crate wasm_bindgen;
use wasm_bindgen::prelude::*;

// Import the `window.alert` function from the Web.
#[wasm_bindgen]
extern {
    fn alert(s: &str);
}

// Export a `greet` function from Rust to JavaScript, that alerts a
// hello message.
#[wasm_bindgen]
pub fn greet(name: &str) {
    alert(&format!("Hello, {}!", name));
}

Use exported Rust things from JavaScript!

index.js:

// Asynchronously load, compile, and import the Rust's WebAssembly
// and JavaScript interface.
import("./hello_world").then(module => {
  // Alert "Hello, World!"
  module.greet("World!");
});
