Configuration helper

Since setting up the configuration helper is a two step process here is a dedicated section for it.

Setting up the helper

// File: lib/config.js

// Import Repository and repositoryHelper
import { Repository, repositoryHelper } from '@industry/helpers';

const data = {
    app_name: 'FooApp',
    blog: {
        title: 'My Blog',
        description: "Just bloggin' around"
    }
};

// Create a Repository instance using the repositoryHelper
const instance = repositoryHelper( new Repository(data) );

// Export the instance
export default instance;

Usage

// File: index.js

// Import previously created instance
import config from './lib/config.js'

const repository = config();
// -> Returns the Repository instance

const title = config('blog.title');
// -> "My Blog"

const defaultTitle = config('blog.foo', 'This is a default value');
// -> "This is a default value"

config(['blog.url', 'https://example.com/blog']);
const url = config('blog.url');
// -> "https://example.com/blog"
