Why?

Building secure web applications that respect people's privacy by considerately storing personal data is an essential skill.

Most beginner's guides gloss over the steps we are about to take together. If you care about your own privacy - and you should! - follow along and see how easy it is to do the right thing.

Why Build This Demo App First?

We will then use these techniques to build something more advanced.

What?

The fields-demo App showcases a registration form for a (fictitious) conference called "Awesome Conf".
