LocalSetup

1. Install python3 and virtualenv and then install dependancies in that venv
   Open terminal and run

virtualenv venv # create a virtual environmnet
source venv/bin/activate #start using that environmnet 
pip3 install -r requirements.txt # install all required packages

2. Collect You Spotify User ID and Oauth Token From Spotfiy and add it to secrets.py file

   • To Collect your User ID, Log into Spotify then go here: Account Overview and its your Username
   • To Collect your Oauth Token, Visit this url here: Get Oauth and click the Get Token button . Check all boxes when you click on get token. Remember this token expires quickly so you might need to update it when ever you run this

3. Enable Oauth For Youtube and download the client_secret.json file Just follow the guide here Set Up Youtube Oauth

   • Go to console google
   • Go to credentials
   • Create credential and choose OAuth client id
   • Application type as desktop app
   • Give any name
   • Simple Download it and save name as "YOUR_CLIENT_SECRET_FILE.json"
     For more information visit How to make OAuth

4. Run the File
   Run following command in the terminal

python3 add_songs.py "your_playlist_name"

* you'll immediately see `Please visit this URL to authorize this application: <some long url>`
* click on it and log into your Google Account to collect the `authorization code` and then paste it back it  

If you see "This app isn't verified", Click on 'advanced' and then on 'Go to testing (unsafe)'

ToDo

Write more useful Readme and put better comments in the code

Troubleshooting

• Spotify Oauth token expires very quickly, If you come across a KeyError this could be caused by an expired token. So just refer back to step 3 in local setup, and generate a new token!

Debugging

• Run the file in interactive mode

python3 -i add_songs.py "your_playlist_name"

• See which function gave you that error. Save all previous variables in shelve (shown in next step)
• Try saving any variables (e.g youtube,spotify_playlist_id) in a shelve. So you don't have to authorise permission from Google each time we run it or run all previous functions again.

with shelve.open('shelve.db') as db:
         db["youtube"] = youtube
         db["spotify_playlist_id"]=spotify_playlist_id

• Then try fixing the code
• Re run the script and load all previous variables like

with shelve.open('shelve.db') as db:
         youtube = db["youtube"]
         spotify_playlist_id = db["spotify_playlist_id"]

• Then run only the functin that was giving the error
• Hopefully this will make debugging easy
