Flyconfig

Simple package to read JSON stored configuration in Node.js environment. The configuration are read based on the current NODE_ENV environment variable.

Setup

The package can be installed directly from NPM by running

npm install flyconfig

How to use

Using the package is obviously simple and straightforward, require the package, load the file, and get the config you need.

A typical use case.

// Returns an instance of Flyconfig
const Config = require('flyconfig');
const path = require('path');
 
// Loads the configuration JSOn file.
const config = Config.load(path.join(__dirname, 'config.json'));
 
// Get a portion from the loaded configuration
let dbUser = config.get('database.host.username');

An Example of the JSON stored config file config.json

{
    "development": {
        "database": {
            "host": {
                "username": "cloud234",
                "password": "oct_093",
                "port": 4628
            }
        }
    }
    "production": {
        "database": {
            "host": {
                "username": "cloud234",
                "password": "oct_093",
                "port": 4628
            }
        },
        "mail": {
            "host": "smtp.mailtrap.io",
            "port": 53,
            "username": "geek44",
            "password": "orange_24"
        }
    }
}

Configuration files are loaded based on the current NODE_ENV, if it is not set, it defaults to development, therefore the developement portion of the config.json is loaded for reference.

API

• Load: The load API is use to load configuration. The load must be called first on the returned instance of Flyconfig object (returned when required) before trying to get any config.

...
config.load('path/to/config');

It required as argument, the resolved path to the location of config JSON file, and return a chainable instance of itself.

• Get: It returns a portion of the requested configuration, or returns undefined if not found. Alternatively, it returns the second optional arguments if it is not found.

config.get(string, [, optional (any)]);

- string: the portion of the loaded configuration required e.g *"database.port"*
- optional argument is returned if the portion is not available within the loaded config.
