Vne NPM | npm.io

vne

A clever .env (made clever-er with env-smart)

Install

npm i vne

Usage

import { vne } from "vne"; // use the named export...
import env from "vne";     // or, the default and name it whatever you want

// Your .env file, made more useful.
console.log(vne()); // or, env();

API

vne(path?)

path

Type: string (optional)

vne has two assumptions about your project: 1) your environment file has a filename of .env and 2) this file in the root of your project. If one of those assumptions are incorrect, you can specify an absolute path to your environment file and vne will use that.

Example

Take this sample .env file:

tokens1="jumb1e-0f-num8er5-and-l3tt3r5"
tokens2="l3tt3r5-and-jumb1e-0f-num8er5"

portDatabase=55555
serviceApi="jumb1e-0f-l3tt3r5-and-num8er5"

dev-api="http://localhost:3000"
prod-api="https://api.domain.tld"

dev-app="http://localhost:3001"
prod-app="https://app.domain.tld"

dev-marketing="http://localhost:3002"
prod-marketing="https://domain.tld"

vne takes the .env file and produces an object like this:

{
  tokens: [
    "jumb1e-0f-num8er5-and-l3tt3r5",
    "l3tt3r5-and-jumb1e-0f-num8er5"
  ],
  portDatabase: "55555",
  serviceApi: "jumb1e-0f-l3tt3r5-and-num8er5",
  dev: {
    api: "http://localhost:3000",
    app: "http://localhost:3001",
    marketing: "http://localhost:3002"
  },
  prod: {
    api: "https://api.domain.tld",
    app: "https://app.domain.tld",
    marketing: "https://domain.tld"
  }
}

Variables with names differentiated by numbers are intelligently placed into an array for easy iteration. A use case would be a handful of tokens you want to have admin access to your API.

Other variables in your .env file with a -, ., or · get placed into a nested object for easy querying. That way, you will be able to do something like this:

const { dev, prod } = vne();

try {
  await request({
    url: process.env.NODE_ENV === "development" ?
      dev.api :
      prod.api
  });
} catch(_) {
  // handle error
}

The above example checks to see if your app is running in a development environment (of course, this assumes that you are setting your environment when starting your app).

Easy-peasy!
