🛠️ Tech Stack

• Backend:

  • Go (Golang) – The backend is built using Go for handling HTTP requests, generating short URLs, and interacting with the database.
  • Gin – A web framework for Go that simplifies routing and middleware.
  • PostgreSQL – A relational database for storing long URLs, their shortened versions, and other metadata like click count.

• Frontend:

  • HTML5 – Basic HTML structure for the user interface.
  • CSS3 – Styling of the application using inline styles (or external stylesheets).
  • JavaScript – For client-side interactivity, such as making API requests and updating the UI dynamically.

• Others:

  • Docker – Used for containerizing the application and the PostgreSQL database for easier deployment.
  • Docker Compose – Simplifies managing multi-container applications (e.g., running both the Go app and PostgreSQL together).
