Chartify

A simple app used to show the Emotional flow of albums and playlists Based off of an Idea by RCharlie https://www.rcharlie.com/post/fitter-happier/

Will connect to Spotify and use Plotly in order to create and build charts Can be used to graph and analyze albums, songs and (eventually) playlists for their emotional highs and lows for proper playlist development. will eventually allow creation of playlists via Spotify's User API

Haven't figured out how to chart the data yet for super long playlists but that's a problem for later

Eventually it may do sentiment analysis using Lyric data but that's far off in the future

Dependencies

to install all dependencies run the following command install Python 3.10.4, VSCode and the python extension for VSCode for easy debug.

***Warning! (If you want to use WSL / linux It'll take like an hour but I'd be glad to give you some links on how to do and configure it to work with VPNs)***

pip install pip-system-certs spotipy flask plotly lyricsgenius

optionally you can use pandas dataframes really easily with plotly. Try with all thy might

as well make sure the following command is run in all terminals

set CURL_CA_BUNDLE="" python

Configuration

you'll need to make a Spotify Developer Account and generate an application in order to run Chartify.

After doing so, fill out the chartify.env.sample file and rename it to the proper chartify.env or you could set them your environment variables in your bash profile but that'd be overkill. Right?

Firing it Up!

to run the app, it's as simple as setting environment variables like those in chartify.env and then calling

flask run

Containerized This time!

or better yet you can run it via containers

docker build -t <somerepo>/chartify:tag .
docker run --name ChartifyAPI --env-file <./path_to_chartify.env> -d -p <available port>:5000 <somerepo>/chartify:tag 

What if I'm scared of Command Lines?

Then there's a shell script! simply call

chmod +x ./build_and_run.sh
./build_and_run.sh <preferred_name_of_tag_or_leave_blank_for_latest>

It will perform the build, kill and remove the running container (if used before) and then run your new build!

and then to test one of the charting methods simply enter the following in your browser

So go ahead

Happy Hunting!
