This project offers NodeJs bindings for the Gazebo simulator (http://www.gazebosim.org/)

• Gazebo must be installed first.
• The version of gazebojs follows the version of Gazebo, so you should use gazebojs 6 if you have Gazebo 6 installed

In addition to Gazebo, you must also install:

• nodejs: sudo apt-get install npm nodejs nodejs-legacy
• jansson: sudo apt-get install libjansson-dev
• libgazeboX-dev (where X is your Gazebo version see http://gazebosim.org/tutorials?tut=install)

Here are the steps for Xenial

mkdir simjs
cd simjs

# install node and gazebo
sudo apt install -y gazebo7 libgazebo7-dev libjansson-dev npm nodejs nodejs-legacy 

# setup an empty node project 
npm init -y
npm install gazebojs

Please take a moment to look at the tutorials: http://gazebosim.org/tutorials?cat=gazebojs

In Ubuntu Trusty (14.04), the default version of Node is 0.10.x. In Ubuntu Xenial (16.04), the default version of Node is 4.2.x

Node 0.10 is compatible with Gazebo 4 to 6, while 4.2.x is required for Gazebo 7 and up. Please refer to the installation tutorial http://gazebosim.org/tutorials?tut=gazebojs_install&cat=gazebojs for more details on how to change your version of Node.
