User Story: As a user, I want the Cloud Reader to support various e-book formats and render them correctly, so that I can read my diverse collection of digital books.

Acceptance Criteria:

  • Given I upload an EPUB file, When I open the book on both the mobile and web application, Then the content should render correctly, maintaining formatting, images, and navigable chapters.
  • Given I upload a PDF file, When I open the book on both the mobile and web application, Then the PDF content should be displayed accurately, allowing zooming and scrolling.
  • Given I upload a book file with a large number of pages/chapters, When I attempt to open and navigate it, Then the application should load and navigate efficiently without significant delays or performance degradation.
  • Given I open a book containing embedded images or multimedia, When I view the relevant sections, Then the embedded content should be displayed correctly within the reader interface.
  • Given I am reading a book, When the book contains a table of contents, Then I should be able to access and navigate chapters using an interactive table of contents.
  • Given A new book format becomes popular, When the system is updated, Then the backend should be capable of processing the new format and serving it to both frontends.
  • Given a book is uploaded, Then the Django backend should validate the file format and size before storing it in PostgreSQL.
  • Given a book is opened, Then the backend API should serve the book content in a streamable or paginated manner optimized for efficient frontend rendering.
