Initialize the WASM runtime

Load flora.js as a script (UMD) and then call createFloraModule with locateFile.

const floraJsUrl = new URL('/wasm/flora.js', window.location.origin).href;
const floraWasmUrl = new URL('/wasm/flora.wasm', window.location.origin).href;

await new Promise<void>((resolve, reject) => {
  const script = document.createElement('script');
  script.src = floraJsUrl;
  script.type = 'text/javascript';
  script.onload = () => {
    if (typeof window.createFloraModule === 'undefined') {
      reject(new Error('createFloraModule not found after loading flora.js'));
      return;
    }
    resolve();
  };
  script.onerror = () => reject(new Error(`Failed to load script from ${floraJsUrl}`));
  document.head.appendChild(script);
});

const module = await window.createFloraModule({
  locateFile: (path: string) => (path.endsWith('.wasm') ? floraWasmUrl : path),
  print: () => {},
  printErr: () => {},
  onRuntimeInitialized() {
    const mod = this as unknown as {
      wasmMemory?: WebAssembly.Memory;
      HEAPU32?: Uint32Array;
      HEAP32?: Int32Array;
      HEAPF32?: Float32Array;
      HEAPU8?: Uint8Array;
    };

    if (!mod.HEAPU32 && mod.wasmMemory) {
      const buffer = mod.wasmMemory.buffer;
      mod.HEAPU32 = new Uint32Array(buffer);
      mod.HEAP32 = new Int32Array(buffer);
      mod.HEAPF32 = new Float32Array(buffer);
      mod.HEAPU8 = new Uint8Array(buffer);
    }
  },
});
