/**
 * net/http has two major components for processing HTTP request:
 * 1. ServerMux: is a multiplexor (or simply an HTTP request router) that compares incoming HTTP requests against
 * a list of predefined URI resources and then calls the associated handler for the resource requested by HTTP client.
 * 2. Handler: The ServerMux provided a multiplexor and calls corresponding handlers for HTTP requests. Handlers are
 * responsible for writing response headers and response bodies. In Go, any object can become a handler by implement
 * http.Handler interface (to implement an interface, we must implement all methods in the list methods signature
 * defined in the interface, here http.Handler interface has only one ServeHTTP method).
 * There are some ways to do it as below

Reading data before application startup in Angular 2

In this demonstration I will show you how to read data in Angular2 final release before application startup. You can use it to read configuration files like you do in other languages like Java, Python, Ruby, Php.

This is how the demonstration will load data:

a) It will read an env file named 'env.json'. This file indicates what is the current working environment. Options are: 'production' and 'development';

b) It will read a config JSON file based on what is found in env file. If env is "production", the file is 'config.production.json'. If env is "development", the file is 'config.development.json'.
