Introduction to Gulp.js

Gulp is a Javascript Task runner. When we are creating Javascript, Html and CSS there’s a lot of little things that we have to do to basically prepare our code either running in a development environment or in production environment.For example minifying and concatenating , adding vendor prefixes, Less to CSS Compilation, Injecting Files Into HTML, Angular Template Cache, Code Analysis and more to our code.

Main API’s In Gulp

  1. gulp.task
  2. gulp.src
  3. gulp.dest
  4. gulp.watch

Installing Gulp

Gulp is created by using Node.js. So you have to install Node.js first , after that we can install gulp and gulp packages using NPM

You can download Node.js from here

In order to get start with Gulp , You have to install it Globally and then install dependent packages and then code your task.

JavaScript date serialization error in WCF POST Request

I have try to send an Ajax Post request from my client. So i am trying to send the DateTime format from client is like ’12/29/2014′ but my server accepts C# datetime. So i got an error like

There was an error deserializing the object of type ‘type’. DateTime content ’12/29/2014′ does not start with ‘\/Date(‘ and end with ‘)\/’ as required for JSON

How to resolve this error?

Write a javascript function like below
function ConvertToJsonDate(date) {
var convertedDate = new Date(date);
var str = Date.UTC(convertedDate.getFullYear(), convertedDate.getMonth(), convertedDate.getDate(), convertedDate.getHours(), convertedDate.getMinutes(), convertedDate.getSeconds(), 0);
var formattedDate = "\/Date(" + str + ")\/";
return formattedDate;
}

Convert your current date before sending request
var params = {
EndDate: ConvertToJsonDate(endDate),
};

Enjoy coding…

Alternative string concatenation of a two string in Javascript

function GetString(string1,string2) {
var str1 = string1.split('');
var str2 = string2.split('');

var finalString = "";
var length = str1.length > str2.length ? str2.length : str1.length;
for (var i = 0; i str2.length) {
var difference = str1.length - str2.length;
for (var i = 0; i < difference; i++) {
var rem = str1[str2.length + i];
finalString = finalString + rem;
}

} else {
var difference = str2.length - str1.length;
for (var i = 0; i < difference; i++) {
var rem = str2[str1.length + i];
finalString = finalString + rem;
}
}
return finalString;
}

var result= GetString(“INDIA”, “USA”);
Output : IUNSDAIA
