# ffmpeg.wasm Electron App

This is a minimal Electron app that runs ffmpeg.wasm in the renderer using the browser build.

Run locally (development):

```bash
npm install
npm start
```

How it works:
- A small static HTTP server is started inside the main process (`main.js`) and serves `index.html` and the `node_modules` browser builds. This ensures the FFmpeg browser core and worker are loaded same-origin and avoids Node worker / blob URL issues.
- For production (packaged) builds this same approach is used (the app starts an internal local server on startup and loads from `http://127.0.0.1:<port>/index.html`).

Build (macOS example):

```bash
npm run build
```

Notes:
- Packaging includes all project files by default due to the basic `files` pattern. Adjust `build` configuration as needed.
- For higher security consider using a custom protocol (`app://`) and disabling `nodeIntegration` (already disabled). You can also move heavy work into the main process via IPC.
