API Assignment Demo

Overview

Refactor the basic example given in the folder before to better enable unit tests to be done.

Changes

Each of the following files has been split into two:

• authorize.js -- becomes authorize.js and authorizeHandler.js
• booksquery.js -- becomes booksquery.js and booksqueryHandlers.js
• favourites.js -- becomes favourites.js and favouritesHandlers.js
• users.js -- becomes users.js and usersHandlers.js

Route handling is now done in the *Handlers.js files, and route-specific functionality appears in the specialised files.

Callback Hell

Note that callbacks are used a lot in this code, to keep the concepts simple. However you can see that these are beginning to make the code messy.

Promises are a much better choice as the equivalent code would be much easier to read and understand.

Testing

Now that the files like authorize.js, booksquery.js, etc. do not contain request and response handling functionality, they can be properly unit tested using jasmine-node or similar!
