The Unix socket to listen to (instead of a host).

Setting it to true will listen to a socket at /your-os-temp-dir/webpack-dev-server.sock:

webpack.config.js

module.exports = {
  // ...
  devServer: {
    ipc: true,
  },
};

Usage via CLI:

npx webpack serve --ipc

You can also listen to a different socket with:

webpack.config.js

const path = require("path");

module.exports = {
  // ...
  devServer: {
    ipc: path.join(__dirname, "my-socket.sock"),
  },
};

Usage via CLI:

npx webpack serve --ipc ./my-socket.sock

1. The script should listen to the socket provided.
2. A proxy server should be created.
3. Go to http://localhost:8080/, you should see the text on the page itself change to read Success!.
