React Application that allows the users to see their Spotify data relating to who their top artists are as festival poster

Create Your Own Festival Poster

Please note, you must have a Spotify account to use this app.

Users log into the app via their Spotify account (implicit grant authorization flow) and are able to view their personalised data relating to who their top artists are displayed as a festival poster line-up.

Deployment

• Demo the project on Netlify: https://create-your-lineup.netlify.app

Stack

• React App, built with CSS.
• App build with mobile-first development in mind.
• Spotify documentation link: https://developer.spotify.com/documentation/

How The Authorization Works:

For more information: visit the Spotify guides for Auth: https://developer.spotify.com/documentation/general/guides/authorization-guide/

• This application uses Spotify's Implicit Grant Authorzation flow, which grants temporary user authorization. -To begin, the user must log into Spotify, heading to https://accounts.spotify.com/authorize with additional parameters in the query string.
• Paramaters I used:
  • client id
  • re-direct url
  • necessary scopes
• example: https://accounts.spotify.com/authorize/clientid/redirecturl/scopes - there are more optional params that can be includes for additional features -This was all put inside a button onClick function to direct the user there when clicking 'log in to spotify'

-Once the user is logged in, they are directed towards my variable 're-direct url', for this project mine is set to the Poster component, and the same time, the users access token is also passed to the application (if they logged in successfully and granted access)

• once redirected, final URL will contain a hash fragment with the following data encoded as a query string
  • access token necessary
  • token type optional, one word that can be written out yourself
  • expires in optiona, but not necessary

-The access token is needed to access the users top artists during the GET request, so I created a function getReturnedParamsFromSpotifyAuth that would extract the token from the URL bu using the reduce method and putting them into an object

• Next I defined a useEffect that would run the above function on page load to get the users access token and save it in localStorage ready for later use.
• using the React hook, useState I defined:
• const [token, setToken] = useState("") and inside the above useEffect I had conditional logic to say, if there is an access token in local storage, do setToken(token-that-was-in-local-storage)

Now that you have the users access token, you are able to do GET requests on their top artists and and have successfully achieved authorization!
