Standalone-Server

• Standalone Server is a web server built using Shelf in dart.
• A sample project with an entrypoint in bin/, library code in lib/, client side code in public/, and example unit test in test/.
• The server serves some static HTML files (including CSS ) & a PDF file. I have implemented user authentication using JWT tokens. Only once the user gets authenticated, He/She can view the PDF or Edit Name.
• To handle authentication on client-side, I have used cookies to store tokens. This ensures flawless and secured frontend-backend communication.
