Project Structure & Module Organization

This repository is a static linear algebra learning app without a build step. index.html provides the page shell, SEO metadata, and script loading order. Application behavior is split across app.js and focused modules such as app.math.js, app.tools.js, app.quiz.js, app.progress.js, app.render.js, and app.viz.js. Keep the script order in index.html: data/learningPath.js must load before the app modules.

Course content and references live in data/learningPath.js. Styling and design tokens are in styles.css; consult DESIGN.md before adding colors or components. PWA files include service-worker.js, manifest.webmanifest, icons, and og-image.svg. Generator utilities live in tools/, while workflows are under .github/workflows/. There is no separate test directory or build output.

Build, Test, and Development Commands

No package installation or build step is required.

python3 -m http.server 8080

Serves the app at http://localhost:8080; use HTTP when checking Service Worker behavior.

node --check app.js
node --check app.math.js
node --check app.tools.js
node --check app.progress.js
node --check app.quiz.js
node --check app.viz.js
node --check app.render.js
node --check service-worker.js
node --check data/learningPath.js
node --check tools/gen-llms.js
node --check tools/validate-content.js
node tools/validate-content.js
node -e "JSON.parse(require('fs').readFileSync('manifest.webmanifest','utf8'))"

These syntax and manifest checks are the project’s automated verification. When lesson content or references change, run node tools/gen-llms.js and commit the regenerated llms.txt and llms-full.txt.

Coding Style & Naming Conventions

Use plain JavaScript, HTML, and CSS without new dependencies. Follow existing two-space indentation and descriptive camelCase identifiers. Keep interface and lesson text in clear German. Preserve HTML escaping for rendered content and security attributes on external links. Lesson IDs are persistent savegame keys; do not rename them casually.

When changing cached assets, increment both CACHE_NAME in service-worker.js and SW_VERSION in app.js, keeping their version numbers aligned.

Testing Guidelines

There is no test framework or coverage target. Run every command above, then manually verify navigation, quizzes, savegame import/export, responsive layout, and offline caching. Content changes should include an updated mini-quiz and curated lesson references.

Commit & Pull Request Guidelines

Use concise Conventional Commit prefixes seen in history: feat:, fix:, docs:, refactor:, perf:, or chore:. Keep commits focused. Pull requests should explain the change, note manual verification, link relevant issues, and include screenshots for visible UI changes. Confirm CI passes before requesting review.
