How to upload a library to Heroku?

Question

git

I'm learning Heroku little by little and I want to put my discord bot on the host, but I can't download the node_modules library. Most likely due to the fact that there are 270+ files. Can anyone suggest how should I proceed?
$ git add .
$ git commit -m "test"
$ git push heroku master
Tried to download with this, but it doesn't work

Answer 1

The node_modules folder does not need to be uploaded to Heroku, it will install all the libraries based on package.json.
