This chapter is an introduction to one of the most important areas of applications on the Galileo board—running a web server. It is relatively easy to run a web server on the board because the Galileo processor runs a simple Linux distribution. This opens the door to a wide range of applications, from simply reading the state of sensors remotely to building bigger web applications based on Galileo.

In this chapter, we will see how to create a basic web server using the Node.js framework along with the Intel XDK software. The combination of these two make things much easier and we will see that it's really simple to run a web server on the Galileo board.
