Composite Music Recommendation API 🎵

This API allows users to search for a song or music group and retrieve information like genres, members, years active, and more.

Using this collected data from serveral scraped websites and APIs, a collection of resulting YouTube videos are presented to the user as recommendations of similar or related music in the same genre and time period. Intermediate results used to come to the final result set are cached within a MongoDB instance.

Features 🌊

• Web interface for easy searching.
• Fetches data from Wikipedia, Bandcamp by scraping data from pages.
• Recommendations are based on a variety of sources (API clients, page scraping), where the results are compared against each other for the purpose of sanity checking and eliminating bad results from a single source.
• In the request lifecycle, API results from each pluggable module are collected, cached and used to sanity check each others results.
• Intermediate module results are cached as graph in MongoDB.
• Pluggable middleware modules defined in a JSON configuration file.
• Music recommendation results are presented as a list of linked youtube videos.
