Content Model

Domain (mathematics, physics, etc.)
  └── Concepts (atomic, reusable)
  └── Courses (structured learning paths)
       └── Chapters
            └── Topics
                 └── Concepts (referenced by ID)

How It Works

GitHub → jsDelivr CDN → Flutter App → Render JSON

No SDK. No npm package. Just JSON over HTTP.

Compilation & Optimization

To minimize network traffic, the content repository compiles domain indices and course cards into consolidated files. This reduces domain and course library discovery down to exactly 1 request each:

• content/domains.json: Generated from all active domain folders. Contains domain names, descriptions, metadata (icons/colors), and course counts.
• content/courses/[domainId]/courses.json: Consolidates all index.json and latest.json manifests for all courses inside a category.

These files are automatically updated and committed to main on every push via the GitHub Actions build workflow.

CDN URLs

// Load latest course version
final response = await http.get(
  Uri.parse('https://cdn.jsdelivr.net/gh/loyality7/grasp-content@main/content/domains/mathematics/courses/calculus/latest.json'),
);

// Load specific version
final response = await http.get(
  Uri.parse('https://cdn.jsdelivr.net/gh/loyality7/grasp-content@v1.0.0/content/domains/mathematics/courses/calculus/versions/1.0.0/course.json'),
);

// Load concept
final response = await http.get(
  Uri.parse('https://cdn.jsdelivr.net/gh/loyality7/grasp-content@main/content/domains/physics/concepts/kinematics.json'),
);
