@live-codes/vb-wasm

VB.NET in the browser: the real Roslyn compiler (Microsoft.CodeAnalysis.VisualBasic) running on .NET WebAssembly. No server, no network round-trips — the code is compiled and run inside the page (or a Web Worker).

This package ships uncompressed assets only. CDNs (jsDelivr et al.) compress responses themselves, so the .br/.gz siblings a .NET publish emits were dropped to stay well under jsDelivr's 150 MB package limit.

Usage

import { createVbRunner } from "@live-codes/vb-wasm";

const runner = createVbRunner({
  baseUrl: "https://cdn.jsdelivr.net/npm/@live-codes/vb-wasm/",
});
const { ok, output, errors, warnings } = await runner.run(
  'Module P\n  Sub Main()\n    Console.WriteLine("Hello from VB.NET")\n  End Sub\nEnd Module',
);

Or with a plain script tag (no bundler):

<script src="https://cdn.jsdelivr.net/npm/@live-codes/vb-wasm/vb-compiler.js"></script>
<script>
  VbRunner.baseUrl = "https://cdn.jsdelivr.net/npm/@live-codes/vb-wasm/";
  VbRunner.run(
    'Module P\n  Sub Main()\n    Console.WriteLine("hi")\n  End Sub\nEnd Module',
  ).then((r) => console.log(r.output));
</script>
