# io.js on raspberry pi

installing io.js is now really easy thanks to the io.js and nvm team.
They provides prebuilt binaries for arm.

## get the system up to date
io.js require packages that are not available on the standard (Wheezy) need to change to Jessie.
Update your package url


```
$ sudo nano /etc/apt/sources.list
```

in the opened file comment the Wheezy package line and add 

```
deb http://mirrordirector.raspbian.org/raspbian/ jessie main contrib non-free rpi
```
Now you need to do a full upgrade 

```
$ sudo apt-get update && apt-get upgrade && apt-get autoremove
```


## install node version manager 
if you have already nvm installed, please be sure to use the latest version (min v0.23.0, ```nvm --version```). two install options are available :

curl script 

```
curl https://raw.githubusercontent.com/creationix/nvm/v0.23.3/install.sh | bash
```

or make a regular installation following [nvm](https://github.com/creationix/nvm)'s instructions

## install io.js binaries

```
$ nvm install iojs
```

will download binaries for io.js and npm and symlink them to node and npm command. 

Go play with es6 !
