@insanai/zenfmt

This package contains zenfmt's dependency-free browser distribution. Document conversion runs in WebAssembly on the caller's machine. The adapter does not upload documents or fall back to a remote conversion service.

npm install @insanai/zenfmt

Use a dedicated worker for browser applications:

import {
  createWorkerConverter,
  wasmUrl,
  workerUrl,
} from '@insanai/zenfmt';

const converter = await createWorkerConverter({
  moduleUrl: wasmUrl,
  workerUrl,
});

const result = await converter.convert(file, { timeoutMs: 30_000 });
console.log(result.text);
converter.dispose();

Some bundlers require an asset rule for .wasm files. The package also exports @insanai/zenfmt/zenfmt.wasm, @insanai/zenfmt/worker, and @insanai/zenfmt/capabilities.json for callers that manage URLs explicitly.

The module has no host imports. It accepts inputs up to 32 MiB and caps linear memory at 1 GiB. The npm package contains the same module, adapter, worker, declarations, and capability contract as the tagged GitHub release.
