Project Summary

Music recommendation service built with PostgreSQL, Spring and Java. Answer a few simple questions and get a playlist of songs based on your answers!

MVP

Our minimum viable product was a service where users could submit a quiz and have a relevant playlist created for them based on their answers, attached to their user id and stored in our database.

Extensions

We also added several extensions:

An admin property for users, where only admins could perform certain actions such as adding new songs and questions to the database
A theme property for questions and songs, so users could choose to answer a quiz or get songs based around a certain topic
A switch song option, where a user could change playlist songs they disliked, for new ones that still matched the quiz answers they gave

How to Set Up and Use

To install the application, clone the repository and run the project or the DemoApplication class in your IDE. The project must be connected to a local database, and the name of this database should be given in the application.properties file, alongside any username and password for it. This should be a new, empty database. The application properties file currently has the database name as 'testspotily', so it may be easiest to set up a database with the same name. The database will be populated with some starter data upon running, as some table entries are provided in the db/migration folder of the repository.
