Dark mode, translation checks, and UI fixes for the freeCodeCamp offliner

Open source · Contributor · March 2026 — Present

Overview

openZIM's freeCodeCamp offliner scrapes freeCodeCamp.org into a ZIM archive for offline use and ships a Vue interface for working through the challenges. My contributions are to that interface: four merged pull requests and one open.

Contributions

Added a visual flash when the "Check Your Code" tests fail (merged March 2026)
Fix reset dialog that showed raw {{title}} and not the lesson name (merged March 2026)
feat: add dark theme using prefers-color-scheme (merged March 2026)
Translation handling (merged March 2026)
Add support for --assignment-- sections in markdown (open)

Details

The dark theme replaced hardcoded colors across the components with CSS custom properties and gave the code editor a dark theme. The translation work added a YAML list of the locale keys the UI uses, a scrape time check that fails the build when locale files do not match, a CI check for unlisted keys, and a single lookup function in the main store.
