E-Book

Our dynamic e-books are crafted chapter by chapter, which are tailored to each course using either the professor’s selected textbook or their own notes.

SmartLearn’s e-book experience offers intuitive highlighting, effortless note-taking, and full offline access. Beyond reading, it’s a seamless, interactive way to stay connected to your course material, anytime, anywhere.

• Firebase Firestore is used to store each chapter as a document within a collection tied to the specific course or user. This structure allows for flexible versioning, easy updates, and real-time syncing across devices.
• Role-Based Access Control (RBAC) ensures that instructors can upload, edit, or lock chapters while students can only view or highlight. Permissions are managed per user type.
• JSON Web Tokens (JWT) secures access to content by validating user sessions. Each time a chapter is loaded, the token is checked to verify access rights and ensure session integrity.

• LocalStorage & IndexedDB are used to stores highlights, notes, and progress on the device for seamless offline functionality. Once the connection is restored, data is synced back to the cloud.
• SmartLearn applies JavaScript DOM Manipulation to enable real-time interaction with content: students can highlight text, click definitions, and insert notes without reloading the page.

• IndexedDB acts as the main offline database, storing entire e-book chapters, embedded media, highlights, and annotations directly on the user’s device. It supports complex, high-volume data and ensures users can continue learning without an internet connection.
• Service Workers (PWA) is used to intercept requests and serves cached content, enabling the e-book platform to work fully offline. Service Workers also manage background sync and push updates when connectivity is restored.
• SmartLearn applies Cache API & Background Sync to cach UI assets and chapter content for faster offline load times. With Background Sync, user actions like note-taking or quiz submissions are queued and automatically synced when the device reconnects.
