Safe .env variable parser for backend-nodejs runtime

I would like to propose an idea to implement a safe .env variable parser that can help us to determine if any required variable is missing or given invalid. For development or production, it can be a good way to plug-in .env variables in a safe mode.

We can define something like:

// src/env.js
const { getEnv } = require('./lib/env-parser');

module.exports = {
  env: {
    mongoUri: getEnv('MONGO_URI', ['string', 'required']),
  },
};

Now, we can use registered variables everywhere we need. Also, if we miss any variable (i.e. MONGO_URI) then it will throw an error or we can also give default values as well.
