confi

Confi

Confi loads configuration data from yaml, json or from a package.json with support for NODE_ENV overrides.

Installation

npm install confi

or

yarn add confi

Usage

Note: confi() is an async method.

Note: Default configuration directory is ./conf/

Configuration files that start with default are loaded and merged together. This allows you to split up configuration logic into smaller files.

You can create a file that matches NODE_ENV which will apply it's values on top of anything set in default. This allows you to create configuration for production and development environments.

User specific configuration can be created as well by placing config files in a users directory inside of the config directory.

./conf/default.yaml

title: 'Example Site'
site:
  name: '{{ title }} - DEV'
updateEvery: '{{ ms("1h") }}
appId: '{{ getEnv("APP_ID", '09830948029384') }}'
shot: false

./conf/users/han.json

{
  "shot": true
}

./conf/production.yaml

site:
  name: '{{ title }}'
updateEvery: '{{ getEnv("UPDATE_EVERY", ms("1h")) }}'

Basic

const confi = require('confi');

async function startApp() {
  const config = await confi();

  console.log(config.site.name); // Example Site - DEV
  console.log(config.appId); // 09830948029384
  console.log(config.updateEvery); // 3600000
  console.log(config.shot); // false
}

startApp();

User

const confi = require('confi');

async function startApp() {
  const config = await confi({
    user: 'han'
  });

  console.log(config.site.name); // Example Site - DEV
  console.log(config.appId); // 09830948029384
  console.log(config.updateEvery); // 3600000
  console.log(config.shot); // true
}

startApp();

Environment

// imagine process.env.UPDATE_EVERY is 10000
const confi = require('confi');

async function startApp() {
  const config = await confi({
    env: 'production'
  });

  console.log(config.site.name); // Example Site
  console.log(config.appId); // 09830948029384
  console.log(config.updateEvery); // 10000
  console.log(config.shot); // true
}

startApp();
