Node.js Application Configuration

Node-config with dynamic configuration

You don't have to restart your Node.js app to apply new configuration. Simply update the configuration files. This repository is forked from lorenwest/node-config and more specifically this Pull Request.

Quick Start

Install in your app directory, and edit the default config file.

$ npm install config-dynamic
$ mkdir config
$ vi config/default.json

{
  // Customer module configs
  "foo": {
    "bar": "fizz"
  }
}

Example express server that returns the config value:

$ npm install express
$ touch index.js

const config = require('config')
const express = require('express')
const app = express()
const port = 3000

app.get('/', (req, res) => {
  const dbConfig = config.get('foo.bar')
  console.log(dbConfig) // Display the updated configuration
  res.send(dbConfig)
})

app.listen(port, () => {
  console.log(`Example app listening at http://localhost:${port}`)
})

Start your app server:

$ node index.js
Example app listening at http://localhost:3000

Poll the server for the latest configuration:

$ curl localhost:3000
fizz

Update config/default.json.

{
  // Customer module configs
  "foo": {
    "bar": "buzz"
  }
}

Poll the server for the latest configuration:

$ curl localhost:3000
buzz
