Stok Config

Stok Config provides a method for loading configuration values form environment variables for twelve-factor apps.

Example

const http = require('http')
const loadConfiguration = require('stok-config')
 
const config = loadConfiguration({
  port: {
    env: 'PORT',
    default: 3000
  }
})
 
const server = http.createServer((request, response) => {
  response.end('Hello!')
})
 
server.listen(config.port)

API

loadConfiguration(config) Returns: Object

Loads configuration from environment variables and the .env file and stores it in a structured object.

• config (Object): A mapping between a structured config object and the associated env vars.

In the following example, web.port will have the value of the PORT env var. Similarly, db.host, db.user, and db.password will have the values of the DB_HOST, DB_USER, and DB_PASSWORD env vars, respectively. db.port will have the value of the DB_PORT env var, but if the env var doesn't exist, the default value of 3306 will be used.

const config = loadConfiguration({
  web: {
    port: 'PORT'
  },
  db: {
    host: 'DB_HOST',
    port: {
      env: 'DB_PORT',
      default: 3306
    },
    user: 'DB_USER',
    password: 'DB_PASSWORD'
  }
})
