I would like to read all the environment variables key and value dynamically and form the array like below:

environment: [
    {
        name: 'DB_NAME',
        value: 'myDatabase'
    },
    {
        name: 'DB_USER_NAME',
        value: 'admin'
    },
    {
        name: 'DB_PASSWORD',
        value: 'admin'
    },
    {
        name: 'DB_TABLE_NAME',
        value: 'myTable'
    },
]

I'm able to print all the environment variables but I'm struggling to get the key and value and form the array dynamically - could someone please help me with this? Appreciate your help in advance. Thanks.

const env = require('dotenv').config();
var environmetList = process.env
console.log("printing env variables", environmetList)
const environment = [];

• What is process.env and what happened to env? Is process.env an object containing the system environment variables or an array of objects with settings? – jabaa Commented Nov 14, 2021 at 21:45

Using Object#entries, get the list of pairs in process.env. Then, iterate over it using Array#map to get a list of objects with name and value:

Object.entries(process.env).map(([key, value]) => ({ name: key, value }))
