Moody Music is a web app that uses color to generate a personalized playlist based on your Spotify listening history.
You can view it at https://moodymusicapp.herokuapp.com.
Moody Music is built with create-react-app and Spotify's Web API. It runs completely client-side and is deployed on Heroku.
Spotify authorization is handled using implicit grant flow, meaning that all account authorization happens in your browser and no account data is being stored by Moody Music. Because of this, tokens expire after an hour, which is why you might be promoted to log in again after periods of inactivity.
The app uses Spotify's Recommendations API to generate the playlist's tracks. It's seeded using your top artists, and the mood is adjusted based on your color selection by tuning various audio features.
Although I used Spotify's API, I'm not affiliated with Spotify.
This app runs on Node.js. Before getting started, make sure you have Node.js and npm installed.
Fork or clone this repository to your local machine, then install dependencies to your local node_modules folder:
$ npm install
In order to run your own builds, you'll need to get your own Spotify developer credentials. Login to the Spotify Developer Dashboard and create an app.
For a local build, you can use http://localhost:3000/ for the website and redirect URI.
Next, copy the Client ID and Redirect URI into src/config.js as CLIENTID and REDIRECTURI.
To run the app in development mode:
$ npm start
Open http://localhost:3000 to view it in the browser.
To build the app for production:
$ npm run build
It correctly bundles React in production mode, optimizes the build for the best performance, and is ready to be deployed!
