Have you ever been curious to see what your Spotify data looks like? How a round-up of your listening habits gets compiled every year? Or even wanted to see metadata of your favorite tracks? Luckily, Spotify makes a ton of interesting data like this accessible via the Spotify API. For example, there is data available for every users’ [top tracks and artists](https://developer.spotify.com/documentation/web-api/reference/#endpoint-get-users-top-artists-and-tracks) of all time and [audio features](https://developer.spotify.com/documentation/web-api/reference/#endpoint-get-several-audio-features) like danceability and tempo for every single track.

## Why this course

If you're interested in accessing personalized Spotify data like we mentioned above, Spotify requires your app to be authorized. And to get authorization, you'll need to implement something called OAuth. This course will walk you through every step of the OAuth flow in a concise, easy to follow way. Unlike YouTube tutorials that only cover a few concepts and leave you with half-baked GitHub repositories, we'll cover everything from explaining what REST APIs are to implementing Spotify's OAuth flow to fetching data from the Spotify API in React hooks. Split into seven modules, each lesson includes clear, detailed explanations and complete code examples. By the end of the course, you'll have an app deployed to the internet that you can share with your friends and add to your portfolio.

## What we’ll build

**On the front end**, we’ll build out a professional, responsive user interface with [React](https://reactjs.org/), React Hooks, and the popular CSS-in-JS library, [Styled Components](https://styled-components.com/). We’ll pull in data from the Spotify API using modern ES6 [async/await](https://developer.mozilla.org/en-US/docs/Learn/JavaScript/Asynchronous/Async_await) methods and display that data in an engaging way.

**On the back end**, we’ll learn the basics of [REST APIs](https://en.wikipedia.org/wiki/Representational_state_transfer), [HTTP requests](https://developer.mozilla.org/en-US/docs/Web/HTTP/Methods), and [OAuth](https://oauth.net/). We'll lift the veil on how to [authorize an app with Spotify](https://developer.spotify.com/documentation/general/guides/authorization-guide/), and then build a Node server with the [Express framework](https://expressjs.com/) to handle our authentication requests. Finally, we’ll deploy our app to the internet using [Heroku](https://www.heroku.com/).

From the last module, we should have a basic Express app set up. Let's review where we are:

Here's our `package.json`.

```json { actualFilename=./protected/src/start/package.json endChar=283 endLine=16 startChar=0 startLine=1 statedFilename=package.json url=https&#x3A;//gitlab.com/fullstackio/books/build-a-spotify-connected-app/module_02/lesson_02.02/protected/src/start/package.json }

And here's our `index.js` file.

const express = require('express');
const app = express();
const port = 8888;

app.get('/', (req, res) => {
  const data = {
