Development Work

Recently:

  • Setup CI / CD process to test and push to a staging server
  • Debugged some JS warnings related to the Vuex state store, and a slightly malformed server response to an API endpoint

Rating by Type of Coffee

Not all cafes will make white, espresso or filter coffees equally, or equally well. Some might have a focus on espresso and bit a little average for the whites, or vice versa. Rather than combining all their ratings and losing that granularity I will let users specify what sort of drink they had when rating a coffee.

WIP UI for selecting drink types

I think this will be important to help give better recommendations. A cafe might do stellar cappuccinos, but if they’re ordinary at a Long Black and that’s what you’re going to order the Cap won’t help you!

The feature does add quite a bit of complexity to the development though. I need to start tracking ratings separately for the drink categories, as well as in aggregate. The scoring algorithm will also ideally weight itself towards a users history and preferences too.

It also has frontend implications with extra UI, state management and icon design requirements. The image above is still, but I am working on building subtly animated SVG icons for the drink types to enhance the UX of choosing them. I’ve got a nice little stepped animation to show the selection action.

SVG

I love the flexibility of images-as-code and being able to add simple animation effects with CSS. I am a little concerned that bundling the SVG icons into Vue components will be adding more weight to the final JS build.

I think referencing a static SVG as an image will prevent me from being able to style and animate individual shapes with CSS. It needs to be an embedded object. When I’m already deep in a Vue component structure that means the icon also needs to be a Vue component (as opposed to server side injected SVG code).

In my defence though, I think most of the audience who are into visiting specialty coffee cafes for entertainment probably err towards having high end phones that are capable of dealing with the load. The JS will be cacheable and probably even service worker cached in the future, so it’s more a CPU/parsing issue.

Backend

Most of the backend adaptations are still to be done though, and the actual search weighting will happen later as I build that feature.

Glad to be Moving to Vuex State Management

The growing amount of data stored for a rated coffee would get difficult to manage within a single parent component. I’m glad I’ve started the work of using Vuex to control the global state. Passing this many props and events up and down the component chain would be quite messy.

Overall Progress

So much of the project framework is complete, but there are a few key features left to build.

  • Drink Type management described here
  • Reverse geocoding and caching so the app can refer to your suburb/city and not just Lat/Long
  • The main cafe search feature, using that geographic information and drink preferences
  • Ability for users to add missing cafes at the time they are entering a review. (This can use some of the existing backend code I have already written from an admin perspective)
  • Service Worker / PWA bundling. This will be very minimal for now. Home screen, and basic asset caching, but no real offline support.
  • Performance and A11Y review

Backend Work

I have made progress recently, but mostly on backend processes that I don’t think are super interesting to read about, and certainly not very visual. Stay tuned (if you want).
