Festify

Festify is a free Spotify-powered app that lets your guests choose which music should be played using their smartphones. festify.rocks

Building

Dependencies

1. nodejs, TypeScript and yarn: Festify is written in TypeScript for better scalability and fewer bugs. We use yarn for package management.
2. Firebase: Festify is built upon Firebase Realtime Database and Firebase Cloud Functions. Set up a dedicated and paid Firebase project. For user management, you need to enable at least anonymous authentication, and if you want cheat-prevention to work, also authentication with GitHub, Facebook, Twitter, and Google+. In that case, you also need to set up and register the respective app / developer accounts with these services.
3. Spotify: Festify plays music from Spotify. Set up a Spotify Developer Application (you need a Spotify Premium account) and configure the OAuth redirect URL. Usually at least http://localhost:3000 is needed for a dev-environment. 3000 is the port the dev-server started with yarn serve runs on, but this can be any port you like, if you configure the dev server accordingly.
4. Fanart.tv & Sentry: Festify displays Fanart from fanart.tv in the TV Mode and uses Sentry for error reporting. You require an account for both services.

Environment Files

Festify loads configuration variables though JS / TS / JSON files included in the build process. All following paths are relative to the repository root.

• common.config.js: This file includes common configuration values that don't deserve their own file. Currently this is the Sentry URL and the Fanart.tv API key. It looks like this:

  export const FANART_TV_API_KEY = "FANART_API_KEY_HERE";
  export const SENTRY_URL = "SENTRY_URL_HERE";

• firebase.config.js: This file contains a simplified form of the config snippet you get when you add Firebase to a web application.

  export default {
      apiKey: "FIREBASE_API_KEY",
      authDomain: "FIREBASE_AUTH_DOMAIN",
      databaseURL: "FIREBASE_DATABASE_URL",
      projectId: "FIREBASE_PROJECT_ID",
  };

• spotify.config.js: This file contains the required configuration for authorization with Spotify and playback.

  export const CLIENT_ID = "YOUR_SPOTIFY_APPLICATION_CLIENT_ID";

• functions/service-account.json: This is the Firebase service account file obtained directly from the web console. You can obtain it by going to Project Settings > Service Accounts > Firebase Admin SDK > Generate new private key.

• functions/spotify.config.ts: This file contains Spotify configuration for the cloud functions.

  export const CLIENT_ID = "YOUR_SPOTIFY_APPLICATION_CLIENT_ID";
  export const ENCRYPTION_SECRET = "REFRESH_TOKEN_ENCRYPTION_KEY - PLEASE GENERATE";
  export const CLIENT_SECRET = "YOUR_SPOTIFY_APPLICATION_CLIENT_SECRET";

Since all config values (except for the service-account.json) are loaded through standard ES modules machinery, building the project will notify you if something is missing.

Building & Serving

The package.json contains all necessary commands for building Festify.

• build: Compiles the TypeScript to JS and bundles all JS to a single file. You can then deploy the files in /build to a webserver of choice to run Festify.
• fix: Attempts to automatically fix linter errors.
• lint: Lints the TS sources with tslint.
• prepare-env: Used in CI environments to load environment files from branch-name-suffixed environment variables.
• serve: Starts the rollup dev-server serving a local instance of Festify on port 3000. Also supports live-reloading. Ensure you deploy the project to firebase before using the dev server because Festify depends on cloud functions to be present!
