node-packenv v1.0.1

Packing JSON object in environment file

Why?

How said in https://12factor.net/config - "The twelve-factor app stores config in environment variables" If you need set complex configuration for your application then need look for workarounds.

This simple tools packenv.js solves this problem.

You may run app with params how it is;

#!/bin/bash
set -e

set -a;
source ./.env_files/.env_cfg;
npm start

If u use docker and docker-compose:

services:
  your-nodejs-app:
    build:
      context: ./
    env_file:
      - .env_files/.env_cfg

Where ./.env_files/.env_cfg - path to u file with PACKENV=...

Install

    npm install [-g] node-packenv

Simple use

pack json

// if u instal how global pack.
$ packenv path_to_ur.json -o .env_file

// or from node_modules
$ ./node_modules/.bind/packenv path_to_ur.json -o .env_file

unpack in your application

const packenv = require('packenv');

const ... =  packenv.parseObjectFromENV();
