Easy HTTP Library

easyhttp.js

// ES5 Object Oriented Library so we use prototypes instead of classes

//Create a constructor
function easyHTTP(){
    this.http = new XMLHttpRequest();
}

// 4 different prototype method

// Make an HTTP GET Request
easyHTTP.prototype.get = function(url, callback){
    this.http.open('GET', url, true);

    let self = this;
    self.http.onload = function(){
        if(self.http.status === 200){
            callback(null, self.http.responseText);
        } else{
            callback('Error' + self.http.status);
        }
    }

    self.http.send();
}

// Make an HTTP POST Request
easyHTTP.prototype.post = function(url, data, callback ){
    this.http.open('POST', url, true);

    this.http.setRequestHeader('Content-type', 'application/json');

    let self = this;
    self.http.onload = function(){
            callback(null, self.http.responseText);
    }

    this.http.send(JSON.stringify(data));
}

// Make an HTTP PUT Request
easyHTTP.prototype.put = function(url, data, callback ){
    this.http.open('PUT', url, true);

    this.http.setRequestHeader('Content-type', 'application/json');

    let self = this;
    self.http.onload = function(){
            callback(null, self.http.responseText);
    }

    this.http.send(JSON.stringify(data));
}

// Make an HTTP DELETE Request 
easyHTTP.prototype.delete = function(url, callback){
    this.http.open('DELETE', url, true);

    let self = this;
    self.http.onload = function(){
        if(self.http.status === 200){
            callback(null, 'Post Deleted');
        } else{
            callback('Error' + self.http.status);
