# libp2p in the browser
This example leverages the [Parcel.js bundler](https://parceljs.org/) to compile and serve the libp2p code in the browser. Parcel uses [Babel](https://babeljs.io/) to handle transpilation of the code. You can use other bundlers such as Webpack or Browserify, but we will not be covering them here.
This example leverages the [vite bundler](https://vitejs.dev/) to compile and serve the libp2p code in the browser. You can use other bundlers such as Webpack, but we will not be covering them here.

Now, if you open a second browser tab to `http://localhost:1234`, you should discover your node from the previous tab. This is due to the fact that the `libp2p-webrtc-star` transport also acts as a Peer Discovery interface. Your node will be notified of any peer that connects to the same signaling server you are connected to. Once libp2p discovers this new peer, it will attempt to establish a direct WebRTC connection.
**Note**: In the example we assign libp2p to `window.libp2p`, in case you would like to play around with the API directly in the browser. You can of course make changes to `index.js` and Parcel will automatically rebuild and reload the browser tabs.
