Mistakes were made A highlight reel from 2018
Who I am
What I did Large project for a small company, everything
from designing table relationships to print stylesheets
Introduced state management (Vuex) too late Refactoring messy events and
state was painful
Should I have known better? NO* Did it require an
urgent fix? YES *https://medium.com/@dan_abramov/you-might-not-need-redux-be46360cf367
Made a prototype Of course it wasn’t a prototype, it’s
in production now
Should I have known better? YES Did it require an
urgent fix? NO* *dumb luck
Mistook easy for simple A complicated theme I know well
is easier than a simple theme I don’t
Should I have known better? YES Did it require an
urgent fix? NO
Asked for too much from the REST API Vue is
easy to extend but don’t ask for everything at once
Should I have known better? YES Did it require an
urgent fix? YES
Didn’t make the impossible not possible “Oh it’ll never do
that” is the worst excuse for making sure it can’t
There were so many failures • Database • API •
Front end js
Should I have known better? YES Did it require an
urgent fix? YES Was it super stressful? YES
BONUS: Firefox print css wtf Printing in FF is insane
Should I have known better? NO Did it require an
urgent fix? YES
The end for now
