# Ethereum JavaScript API
This is the Ethereum compatible JavaScript API using `Promise`s
which implements the [Generic JSON RPC](https://github.com/ethereum/wiki/wiki/Generic-JSON-RPC) spec.
For an example see `index.html`.
**Please note this repo is in it's early stage.**
If you'd like to run a WebSocket ethereum node check out
[go-ethereum](https://github.com/ethereum/go-ethereum).
To install ethereum and spawn a node:
```
go get github.com/ethereum/go-ethereum/ethereum
ethereum -ws -loglevel=4
```
