Steps for assigning a URI as a variable based on the environment, whether it is in production or not

Seeking advice on deploying a MERN app onto Heroku. I have the mongodb URI declared in a config file locally, but on Heroku I am using process.env.mongoURI. How can I adjust my code to use the local config file when running locally and the Heroku config when running on Heroku? Here is what I have attempted so far.

if (process.env) {
  const keys = null
} else {
  const keys = require('./config/keys')
}

let db = '';
if (process.env) {
  db = process.env.mongoURI
} else {
  db = keys.mongoURI
}

javascript mongodb express heroku

My method involves creating separate configuration files for various environments. Here's an example:

Sample config file structure:

const environment = {};

environment.development = {
    mongoURI: 'Your development mongo URI',
    port: '5000',
    secret: "YOUR DEVELOPMENT SECRET"
};

environment.production = {
    mongoURI: 'Your production mongo URI',
    port: 'YOUR PRODUCTION PORT',
    secret: "YOUR PRODUCTION SECRET"
};

var currentEnvironment = typeof(process.env.NODE_ENV) == 'string' ? process.env.NODE_ENV.tolower() : "";

var environmentToExport = typeof(environment[currentEnvironment]) == 'string' ? environment[currentEnvironment] : environment.development;

module.exports = environmentToExport;

Ensure that you have NODE_ENV set on your local machine to ensure this setup works correctly.
