Offline Owl

I really like Duolingo; however, even as a Plus subscriber, their amazing dictionary remains online-only, which prevents me from looking up words I have forgotten on-the-go while in Korea. Additionally, some courses (such as the Korean one) do not have lessons built into the app, and therefore cannot be studied offline.

This repository provides two projects:

• In bin, a Node.JS CLI app can scrape a Duolingo course to export all vocabulary and lessons from it, generating a .dat file.
• In app, an offline-first PWA that can query the generated .dat file is provided.

Since recent JavaScript features are used throughout the project, both the browser and Node.JS must have relatively recent versions.
