Configure your Node.js Applications

Introduction

Node-@devtea2025/magni-impedit-quo-quibusdam organizes hierarchical @devtea2025/magni-impedit-quo-quibusdamurations for your app deployments.

It lets you define a set of default parameters, and extend them for different deployment environments (development, qa, staging, production, etc.).

Configurations are stored in @devtea2025/magni-impedit-quo-quibusdamuration files within your application, and can be overridden and extended by environment variables, command line parameters, or external sources.

This gives your application a consistent @devtea2025/magni-impedit-quo-quibusdamuration interface shared among a growing list of npm modules also using node-@devtea2025/magni-impedit-quo-quibusdam.

Project Guidelines

• Simple - Get started fast
• Powerful - For multi-node enterprise deployment
• Flexible - Supporting multiple @devtea2025/magni-impedit-quo-quibusdam file formats
• Lightweight - Small file and memory footprint
• Predictable - Well tested foundation for module and app developers

Quick Start

The following examples are in JSON format, but @devtea2025/magni-impedit-quo-quibusdamurations can be in other file formats.

Install in your app directory, and edit the default @devtea2025/magni-impedit-quo-quibusdam file.

$ npm install @devtea2025/magni-impedit-quo-quibusdam
$ mkdir @devtea2025/magni-impedit-quo-quibusdam
$ vi @devtea2025/magni-impedit-quo-quibusdam/default.json

{
  // Customer module @devtea2025/magni-impedit-quo-quibusdams
  "Customer": {
    "dbConfig": {
      "host": "localhost",
      "port": 5984,
      "dbName": "customers"
    },
    "credit": {
      "initialLimit": 100,
      // Set low for development
      "initialDays": 1
    }
  }
}

Edit @devtea2025/magni-impedit-quo-quibusdam overrides for production deployment:

 $ vi @devtea2025/magni-impedit-quo-quibusdam/production.json

{
  "Customer": {
    "dbConfig": {
      "host": "prod-db-server"
    },
    "credit": {
      "initialDays": 30
    }
  }
}

Use @devtea2025/magni-impedit-quo-quibusdams in your code:

const @devtea2025/magni-impedit-quo-quibusdam = require('@devtea2025/magni-impedit-quo-quibusdam');
//...
const dbConfig = @devtea2025/magni-impedit-quo-quibusdam.get('Customer.dbConfig');
db.connect(dbConfig, ...);

if (@devtea2025/magni-impedit-quo-quibusdam.has('optionalFeature.detail')) {
  const detail = @devtea2025/magni-impedit-quo-quibusdam.get('optionalFeature.detail');
  //...
}

@devtea2025/magni-impedit-quo-quibusdam.get() will throw an exception for undefined keys to help catch typos and missing values. Use @devtea2025/magni-impedit-quo-quibusdam.has() to test if a @devtea2025/magni-impedit-quo-quibusdamuration value is defined.

Start your app server:

$ export NODE_ENV=production
$ node my-app.js

Running in this @devtea2025/magni-impedit-quo-quibusdamuration, the port and dbName elements of dbConfig will come from the default.json file, and the host element will come from the production.json override file.
