The next big feature I’ve been meaning to add to HustleTime is a way for users to ignore specific train lines.
Let’s say you’re on lower level at West 4th street station in manhattan, and you need to take the 
to Brighton Beach but all you’re seeing in the HustleTime Ui is other trains that are of no use to you. This feature will allow you to ignore 
trains so that you’ll only see the train you need.
How can I accomplish this?
At it’s most basic level the Front end will need to send something to the back end and the back end will need to send the requested information sans the ignored stations. It will also be necessary to save the ignored lines into both state and the phone memory, so that a user will not need to select ignored trains every time they open the app. We also need to make sure the back-end is backwards compatible with prior versions without the ignore feature. Finally, we need a way for the user to actually select the stations they hope to ignore.
How to get started is always tricky for me: I never know where to start. As HustleTime gets more complex, it will become more challenging to decide how to begin modifying all the various moving parts – and I’m sure as I become more experienced as a developer, this process will become easier and easier.
Real Estate
The screen on a mobile device has very limited real-estate. I have a modal built into HustleTime already, and that shows you your saved favorite places.
With the limited amount of space, I think it will probably be best to display the ignore options in a separate tab of the menu. Something like this…
There, I’ll put checkboxes for the various lines, each checkbox will toggle a boolean value in state for each of these lines.
I’ll then JSON.stringify that object when I save it to phone memory or send it to the back-end. In tomorrow’s post I’ll have something to show in regards to my progress on this feature.
