DNS MX Record Web Application

A web application that displays the IP addresses and mail hosts associated with a user-entered domain name.

Requirements

· The application must listen on port 8080

· When accessing the root app (http://localhost:8080/), display a form asking for a domain name (e.g. domain.com)

· When that value is submitted, display the IP addresses associated with the domain and the hosts associated with that domain's DNS MX records.

· If the results page is accessed with the HTTP Accept header set to "application/json", render a JSON response instead of HTML

o Note, in this case, the Accept header will only be "application/json". 

Installation

$ go get github.com/edson-martins/dns-mx-record
$ cd dns-mx-record
$ go mod init

Prerequisites

This application is using the libraries below as dependency:

1 - Golang logging library - github.com/op/go-logging

$ go get github.com/op/go-logging

2 - gorilla/mux - github.com/gorilla/mux

$ go get -u github.com/gorilla/mux

Getting Started

1 - There is a contants.go file used to store the URL Port (default is 8080) and the Index template path. If you want to change the host port, that's the place.

2 - The program can be executed in the project root path (path where the main.go file is available) using the command below:

go run main.go

3 - The build process looking to generate the executable can be done as:

go build
go install

The main file executable will be installed on $GOPATH/bin and the dependecies at $GOPATH/pkg
