AUX is a clone of bandcamp. It features many core features of bandcamp. At this state, it allows users two types of accounts, file upload and download, album streaming, search, and cataloging features for musicians.

I built AUX's server using Rails, ActiveRecord, and Postgres. I used jbuilder to limit Ajax queries and normalize my state. In the future, I would like to implement GraphQL in this project to clean up communication between the DOM and my server and to learn more about databases in general.

The front end of AUX is built on React and Redux. I used withRouter, lodash, and a few other modules to keep things running smoothly. AUX is styled with vanilla CSS with intentions to migrate to Sass as the project grows.

The database is a web of associations, using inverse associations to eliminate unnecessary ajax calls. Searching the tables of the database uses pg_search, a gem allowing multisearch functionality by generating an indexed table of search objects. The results are parsed with a jbuilder and passed to the frontend as a slice of state.

The auth page of AUX signs in two classes of user using the same create controller action. This cuts out unwanted database complications and allows single-file rendering of the three auth types. Artist-class users are allowed and required to possess more parameters than normal users. This additional information is stored in a seperate table. The current solution uses accepts_nested_params to validate the user and the artist profile parameters it optionally carries. In trying to save the user, ActiveRecord also tries to save the associated artist record, rolling back both if one fails.

Efficient interaction with the database is essential to growing AUX into a richer web app. Information rendered by AUX components is rarely pulled from a single table. To fetch just the data needed from all the tables using one ajax query, I implemented succinct jbuilders and re-used data that was already rendered. Modularizing React components to use this style of database query led to functional development styles within React components.

AUX is designed closely after bandcamp, focused on intuitive and visually pleasing placement of components. Some components were left out: the alternative sign-in modal and the altered color scheme on some of the nav bars.

Current priorities for AUX are database migration, genre implementation, and better search through filter bars. Back burner plans include social integration and algorithmic listening suggestions.
