</script>

Usage

You should be able to just import and use this JavaScript package like any other. The WASM magic is hidden behind a really nice wrapper layer.

import {
  greetMany,
  run,
  getReport,
  computeArea,
} from "hello-world-rust-wasm-component-lib";

run();
//=> Hello Alan Turing!

console.log(getReport());
//=> {
//     bouncyCastles: 100,
//     funPercent: 0.9,
//     catCount: 8,
//     unicornNames: [ 'Fluffy', 'Marshmallow', 'Sparkles' ]
//   }

console.log(computeArea({ center: { x: 0, y: 0 }, radius: 6 }));
//=> 113.09733552923255

console.log(greetMany(["Alan Turing", "Ada Lovelace"]));
//=> Hello, Alan Turing!
//   Hello, Ada Lovelace!

Development

Versioning scheme: Use 1.2.3+4.5.6 where 1.2.3 is the main JS bindings API version (this package) and 4.5.6 is the version of the upstream WASM underlying library that was used to generate the JavaScript bindings. The 1.2.3+4.5.6 versioning scheme was adopted so that users of a particular version can quickly see which version of the WASM library was used. Note that the +4.5.6 part is just metadata. You can't publish both 1.2.3+4.5.6 and 1.2.3+7.8.9. Think of it like a super important "description" field.
