==>Creating a URL shortener is a great project that leverages databases, ORMs, and database diagrams effectively. Here’s how you can approach building a URL shortener using Python with SQLite3 and SQLAlchemy.
Project: URL Shortener
Features
-
Shorten URLs
- Accept long URLs and generate short URLs
- Ensure unique short URLs -Optionally, allow custom short URLs
2.Redirect Short URLs
-Redirect users to the original URL when
they visit the short URL
3.URL Analytics
-Track the number of visits to each short
URL.
4.User Management(OPTIONAL)
-Allow users to register and manage their
short URLs .
-Implement user authentication(login/logout)
5.Database Diagram
-Visual representation of the database
schema using tools like dbdiagram.io or
SQLAlchemy's build-in features
Steps to Implement
1.Setup the Project
-Create a new directory for your project
-Set up a virtual environment
-Install necessary dependencies: flask,
** sqlalchemy*, **flask_sqlalchemy,
**flask_migrate*
2.Database Design
-Define the database schema using SQLAlchemy
models
-Create tables for URLs and Users (if user
management is implemented)
3.Database Diagram
-Use a tool like dbdiagram.io to create a
visual representation of your database
schema
-Alternatively, use SQLAlchemy to generate
the schema and visualize it using a library
like ERAlchemy
4.URL Shortening Logic
-Implement logic to generate short URLs
-Handle URL collisions to ensure unique short
URLs
5.Redirect Logic__
-Implement route to handle redirection from
short URLs to original URLs
6.Analytics
-Track and store analytics data such as
visit counts and access dates
7.User Management (Optional)
-Implement user registration and login using
Flask-Login or Flask-Security
-Allow users to manage their short URLs
8.Testing and Deployment
-Write unit tests for your application
-Deploy the application using a service like
Heroku or AWS
