Our Vocab Victor word learning (smartphone) app helps English language students build and strengthen their vocabulary by playing word games.
Our NEW Vocab Victor Classroom app (app.vocabvictor.com), written entirely in Anvil, is a classroom management tool that lets teachers create schools, add classes, create custom word lists and assign the lists to students, which lets their students learn the teacher’s words inside the app.
COOL TECH HACKS:
Serverless model: We determined that the Anvil Tables system, while handy, led to very slow performance. Therefore, we decided to use a serverless model and wrote a python + js library to read/write to Google’s Firestore. It is lightning fast, extremely reliable, and allowed us to write the entire application with very few (I think maybe three or four) server functions.*
Cloud functions: One advantage to the serverless model is that we can write cloud functions on Google that run in response to database actions. All in Python of course .
Connection with app server: The Vocab Victor mobile app has its own API library that generates word games for each individual user. In order to get the Anvil system/cloud functions talking to the app server, we wrote a new API library to add classes and word lists, to assign word lists to our registered app users, and to let the teachers monitor word learning progress based on in-app performance.
Plot control: Used Anvil’s plot control to display word progress to the teachers; took about five minutes to set up!!!
Mobile app experience: Leveraged existing features in the mobile app to show the users their assigned word lists, their word learning progress, and added new features to let them join a class using a Vocab Victor Classroom code (this is actually the thing that hooks everything up). Modified our existing Global leaderboard so that students in a class can compete against each other.
We are very tired.

You are welcome to check out Vocab Victor Classroom (registration is required but free). If you want to play around in the app, please use a school name such as “Anvil test” so I’m not confusing you with “real” users (teachers)! To play around with cloud services, create a bunch of schools and watch how fast they load!
