// conf.json file
{
  "confA": "conf.json",
  "confB": "conf.json"
}

# conf.yaml file
confB: "conf.yaml"
confC: "conf.yaml"

import CatConfig from 'cat-config';

const CONF = CatConfig({
  confA: 'v_1',
  confB: 'v_2',
  confC: 'v_3'
})
  .env()
  .json()
  .yaml()
  .exec();

console.log(CONF);
/*
{
  foo: 'bar',
  confA: 'conf.json',
  confB: 'conf.yaml',
  confC: 'conf.yaml'
}
*/

set config from docker-compose.yml

# docker-compose.yml
version: '3.9'

services:
  node:
    image: nodejs
    environment:
      CONF: |
        keyA: value_A
        keyB: value_B

import CatConfig from 'cat-config';

const CONF = CatConfig({
  keyA: ''
  keyB: ''
})
  .loadEnv()
  .exec();

NODE_ENV

load config file with NODE_ENV environment \ if NODE_ENV not set default is dev

const CONF = CatConfig({})
  .yaml()
  .js()
  .json()

If NODE_ENV is not set cat-config will load file

• conf.yaml
• conf.dev.yaml
• conf.js
• conf.dev.js

If NODE_ENV is set to test cat-config will load file

• conf.yaml
• conf.test.yaml
• conf.js
• conf.test.js

you can set conf.dev.* in .gitignore file
