Facilitating high-level interactions between Wasm modules and JavaScript
0d18c8c397
This came up in a [recent comment][1] and it turns out we're accidentally generating two `const ptr = ...` declarations, invalid JS! While Node doesn't catch this it looks like firefox does. [1]: https://github.com/rustwasm/wasm-bindgen/issues/329#issuecomment-411082013 |

wasm-bindgen
Facilitating high-level interactions between wasm modules and JavaScript.
Import JavaScript things into Rust and export Rust things to JavaScript.
#![feature(use_extern_macros)]
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 with ECMAScript modules!
import { greet } from "./hello_world";
greet("World!");
