Asia Pop 40 Spotify Playlist Auto Update

This project's purpose is to automate the process of updating Asia Pop 40's playlist in spotify.

Prerequisites

Node with NPM

Using asia-pop-40-spotify-playlist

Make sure you have your application registered in spotify, put localhost:3000/get-token-hash for the redirect URL.
Run

touch ./src/temp/uris.json
cp .env.example .env # and then fill it out
npm install
npm run start

Why in Javascript / Node.js

At first I didn't have any reasons particular in mind. I just wanted to learn about Node.js further (I've developed in MERN stack for about 1 month) and after while doing this project, I noticed that I don't know anything. One advantage of using Javascript is that it has a lot of libraries that later I used in this project. Other than that, I think the downside of Javascript is that promises are a headache.

The Runtime Order of The Project

You can see this inside src/index.js

Runs puppeteer to download "Most Recent Chart.csv" from airtable and then rename it into "src/temp/ap40.csv". getAP40csv()
Extract the data from ap40.csv. parseAP40csv()
Starts server to get the redirected token from Spotify API startServer()

Why do you have to use a server?

Because I use authorization code flow. Every authorization flow needs redirect_uri in their query parameter (except client credentials, but the scope of client credentials flow is so small) , and they returns the token inside the url (either hash parameter or query parameter). Server is needed to send the token into node code.
Starts puppeteer and getting the authorization code. automateSpotifyToken()
Exchanging the authorization code into access token. getSpotifyAccessToken()
Removes all songs from the playlist while searching the songs from the chart in spotify. removeSpotifyPlaylistSongs

How does it removes the previous songs, meanwhile Spotify API can't removes songs immediately?

By saving the previous added song uris into a file called uris.json.
Adds the searched songs to the playlist. addSpotifyPlaylistSongs()
Update the title. updateSpotifyPlaylistTitle()
