dwgdxf

Client-side DWG → DXF converter that runs entirely in the browser or server. Powered by acadrust compiled to WebAssembly via Rust.

Supports DWG versions R13 through R2018 (AC1012–AC1032).

Usage

By default, init() uses the local WASM assets from dist/wasm shipped inside the package. Most bundlers (Vite, Webpack 5, Rollup) automatically copy these assets to your build directory via the new URL(...) detection.

If you want to load the WASM assets from a public CDN to keep your application bundle completely free of WASM files, pass the OOTB CDN_WASM_BASE URL:

import { init, convertDwgToDxf, CDN_WASM_BASE } from 'dwgdxf';

// Option A: Initialise using CDN assets (no local configuration required)
await init({ wasmBase: CDN_WASM_BASE });

// Option B: Initialise using local assets (default)
// await init();

// Perform the conversion
const response = await fetch('/models/drawing.dwg');
const dwgBytes = new Uint8Array(await response.arrayBuffer());
const dxfBytes = await convertDwgToDxf(dwgBytes);

// Process the output
console.log('DXF data generated successfully, size:', dxfBytes.length);

Server Support

The loader automatically detects Node.js/Bun environments and falls back to reading WASM binaries directly using fs filesystem APIs since fetch on file:// URLs is not supported out of the box in Node.js.
