To start the demo, run node index.js 5000 and then go to your web browser and
navigate to http://localhost:5000/.
There are two versions of the demo, at http://localhost:5000/
and at http://localhost:5000/index-v2.html.
The first version (index.html and script.js)
includes all the templates in the webpage, while the second version
(index-v2.html and script-v2.js)
is just an application shell and the page templates are dynamically retrieved
from the server via AJAX and stored within the fragments directory.
There are also two database model implementations, the
models/tax-dao.js and
models/tax-orm.js. One implementation uses SQLite
directly and the other uses Sequelize as an ORM. To switch between the two,
uncomment the code in controllers/tax-api.js, lines
4, 15 and
33, and comment out lines
3, 16,
32 and 34. There are
two APIs implemented: /api/taxes and /api/taxes/:code.
