@holoscript/wasm

WebAssembly parser for browsers. Compile HoloScript in the browser without server-side compilation.

Installation

npm install @holoscript/wasm

Usage

Basic Parsing

import { HoloScriptWasm } from '@holoscript/wasm';

const wasm = await HoloScriptWasm.load();
const result = wasm.parse(`
  composition "Demo" {
    object "Cube" { @grabbable geometry: "box" }
  }
`);

console.log(result.ast);
console.log(result.diagnostics);

In-Browser Compilation

const result = wasm.compile(ast, {
  target: 'webgpu',
  optimize: 'balanced',
});

console.log(result.code); // Compiled output

Real-time Validation

const validator = wasm.createStreamingValidator();

document.addEventListener('input', (e) => {
  const code = e.target.value;
  const errors = validator.validate(code);

  // Show errors in UI
  showErrors(errors);
});

Performance

• Parser: ~5ms (WASM optimized)
• Validation: ~3ms
• Small WASM module: ~50KB
• No server round-trip

Supported Targets

Browser-compatible targets evolve over time. Verify current target keys from ExportTarget and test per-runtime support:

• WebGPU
• Three.js
• GraphQL schema
• TypeScript
• And more...
