node-yaml-config

Write your configuration files for node.js in yaml

Installation

npm install node-yaml-config

Usage

var yaml_config = require('node-yaml-config');

var config = yaml_config.load(__dirname + '/config/config.yml');

console.log(config); 

Or with Typescript:

import { loadAsync } from 'node-yaml-config';

async function main() {
  const config = await loadAsync(__dirname + '/config/config.yml');
  console.log(config);
}
main();

Configuration Files

In your configuration file:

default:
  server:
    port: 3000
  database:
    host: 'localhost'
    port: 27017
development:
  database:
    db: 'dev_db'
test:
  database:
    db: 'test_db'
production:
  server:
    port: 8000
  database:
    db: 'prod_db'
    user: 'dbuser'
    password: 'pass'
  cache:
    dir: 'static'

node-yaml-config takes the configuration found in default, then overwrites it with the values found in the environment specific parts. The configuration file is loaded synchronously.

API

read(filename)

Reads the configuration found in filename.

load(filename[, env])

Load the configuration found in filename with the environment based on NODE_ENV. The environment can be forced with the env argument.

node-yaml-config keeps parsed yaml files in memory to avoid reading files again.

reload(filename)

Reload the configuration found in filename. Later calls to load will show the new configuration.

The file is loaded synchronously.

readAsync(filename)

Same as read but returns a Promise.

loadAsync(filename[, env])

Same as load but returns a Promise.

node-yaml-config keeps parsed yaml files in memory to avoid reading files again.

reloadAsync(filename)

Same as reload but returns a Promise.
