About the project

This API allows you to search for information about artists, albums, and songs. You can retrieve details such as the name, duration, description, and more for these entities. Additionally, this API provides a user authentication system using JWT for authorization and utilizes Redis cache to enhance performance and improve response times.

Built With

This is a web application built using Flask, Python, and SQLAlchemy. By default, the application is configured to use SQLite as the database backend. However, if you prefer to use a different database, you can easily switch to PostgreSQL by updating the configuration settings in the config.py file. Additionally, this application utilizes Redis for caching purposes, which helps improve performance and reduce the load on the database..

Add Dummy Data

You can add dummy data to the application using the Flask interactive console. To open the interactive console, open the terminal and run the following command:

flask shell

Then execute this:

from musicapi.dhelper import DummyHelper

d = DummyHelper()

The dummy data is intended for testing purposes only and is generated by ChatGPT. Therefore, it is not realistic and should not be used for production purposes.
