This project was built in python to illustrate the usability and flexibility of flask in combination with SQL-Alchemy. Finally after the entire project was developed it was then deployed in the Heroku Cloud (https://one-and-only.herokuapp.com/). CRUD operations are performed on the available products in the website. For Online Payment, a payment gateway named as Stripe is integrated withing the website so that effective payments can be carried out. An Admin Dashboard is also available only to the admins of the website where they can track every order. The front-end using HTML & CSS was created. Flask provided a smooth link to database and front-end REST architecture. Upon authentication, the client or user can access the website via his credentials. Search functionality is also included so that the customers can search the exact product from the list of available products. Furthermore, addition, deletion, updating, sale, and search of products can be done as well.
