Spotify Authentication Flow Example With Ruby Webrick Webserver

This tutorial will replace Node.js with Ruby in the Authentication Flow example app for Spotify Web API.

This flow first gets a code from the Spotify Accounts Service, then exchanges that code for an access token. The code-to-token exchange requires a secret key, and for security is done through direct server-to-server communication. In this example we retrieve data from the Web API /me endpoint, that includes information about the current user.

Here we will use Ruby for server-side applications.

Installation

First you need to clone the repository.

$ git clone https://github.com/azolf/spotify-web-api-auth-examples-ruby.git

Then you should go to the directory and install the required Gems.

$ cd spotify-web-api-auth-examples-ruby/
$ bundle install

You could edit the Spotify Client Id and Client Secret in server.rb file.

...
$client_id = ENV['CLIENT_ID']
$client_secret = ENV['CLIENT_SECRET']
...

Or you could pass them as environemnt variables.

$ CLIENT_ID=YOUR_CLIENT_ID CLIENT_SECRET=YOUR_CLIENT_SECRET ruby server.rb

Using Docker Image

You could also use pre built docker image.

$ docker pull azolf/spotify-web-api-auth-examples-ruby
$ docker run -itd \
--name spotify-web-api-auth-examples-ruby \
-p 8000:8000 \
-e CLIENT_ID=YOUR_CLIENT_ID \
-e CLIENT_SECRET=YOUR_CLIENT_SECRET \
azolf/spotify-web-api-auth-examples-ruby:latest

Using docker-compose

You could also clone the repository and start the container with the docker-compose.yml file. You just need to replace your Client Id and Client Secret in it.

...
    environment:
      - CLIENT_ID=YOUR_CLIENT_ID
      - CLIENT_SECRET=YOUR_CLIENT_SECRET
...

$ docker-compose up -d

Then, open http://localhost:8000 in a browser.
