How to write to enviornment variables on heroku-CodePudding

Don't eat me in the comments
I have made a website ment to me used by only one person
so i want to dynamically write to .env file on heroku without it restting
because this is ment only for one person i dont want to deal with a database
Something like this

require(`dotenv`).config();

console.log(process.env.MYVAL); // Not my val
process.env.MYVAL = "MYVAL"
console.log(process.env.MYVAL); // MYVAL

You can set the environment variables in the settings tab on your heroku dashboard and also using the command line. Please check the following doc to get more info.

Thanks

You need to persist data (even if it is a single value) therefore you should not write to Heroku file system nor storing it in environment variables (Heroku config vars).

I understand using a DB could be not worth it, in this case I would use an external file storage (S3, dropbox, even using Github private repository).

On Files on Heroku you can see some options and (Python) code
