# WIP - This example is still in the works # libp2p running in the Browser
![](http://1.bp.blogspot.com/-tNvSnCW0KlQ/U-KOKGVoJkI/AAAAAAAAA3Q/aiSLMeSJFtw/s1600/WIP-sign.jpg)
One of the primary goals with libp2p P2P was to get it fully working in the browser and interopable with the versions running in Go and in Node.js.
# 1. Setting up a simple app that lists connections to other nodes
Simple go into the folder [1](./1) and execute the following
```bash
> cd 1
> npm install
> npm start
# open your browser in port :9090
```
