Node.js RESTful API Example

An example about how to create a RESTful API using Express.js. The four CRUD operations are provided: create, read, update and delete records. This server keeps an array of JSON objects in memory and runs the CRUD operations on it. If the server is restarted everything returns to the initial configuration (12 event objects).
