Node.js
is a platform built on
Chrome's JavaScript runtime
for easily building fast, scalable
network applications.
Recipe 6.2
shows how to use the node server that's already running.
This recipe shows how easy it is to build your own server.
First, create a directory for this recipe:
bone#
mkdir serverExample
bone#
cd serverExample
Add the code in
Example 6-2
to a file called
server.js
in the
serverExample
directory.
