How to interact with Heroku from a js file

Question

I have a python file named myfile uploaded on github and heroku app linked to that github repo.

Now when I run heroku run myfile.py on CLI of heroku it is working fine with the output as a string.

Also ,

• I have a html page (in the same repo) hosted by heroku .

So what I want is when user clicks a button in the page,

• heroku run myfile.py command should be run on heroku .
• and my page should fetch the output string from heroku .
• output should be displayed on the page .

Anybody knows how to do this (in the script section of html ) ?

Answer 1

The easiest way would be to change how myfile.py works, and to have it expose an API.

Using a tool such as gunicorn, you could expose an HTTP endpoint to your app. Your Javascript would then be able to make a call to that endpoint, and retrieve any response it sends.
