This is essentially a refactoring of http://jsdo.it/hakim/core (archive) plus a little improvent on entertainment: core is about shield, while ship is about fire.

In this gist I show a simple setup for helping me build the frontend of a backend functionality before programming the latter. In this case it is the login functionality.

On the login page there are three buttons to allow me to login with different credentials, so that I can see what the server would tell me in each case. That will guide me to understand how I want to program the frontend.

A couple of seconds after clicking each button I'll get a response from the server.

1. the first button will cause an error response, which I show in a feedback field on the login page.
2. the second and third buttons will cause an OK response, which I store in the auth key of the local storage system.

How to work on a software project

Describe it

Clearly state what the application is going to do. You'll do this at all levels. Starting from a one liner and getting down to any level of detail. This will help you understand the different things you will need to provide (not only code). And most importantly you will understand better what are the limits of your application, what you don't want just now or never to belong to it.

Structure it

// Use Gists to store code you would like to remember later on
