The process of reducing the size of files like HTML files, cascading style sheets or Javascript is called minification. It is done by eliminating things that are not required by browsers to use files. The main aim is to make the source code of a page small.

White spaces are one such thing that can be eliminated from the code of a site to make it smaller. Some web programmers add blank lines and spaces in their code to make it easy to read. These white spaces are meaningless to search engines and web browsers. Here, these lines get ignored by the search engines. These white lines and blank spaces increase the file size and removing them from the source code of a site can make the file size much smaller.

How is it different from compression?

At the concept level, minification may be similar to compression of a file. Both these things aim to reduce the size of the file. However, these two are not the same thing. The main difference is that compressed files need to be decompressed first before opening them. However, when a source code is minified, there may be no need to decompress the files.

What are the things that can be minified?

Minimum works best for languages ​​like JavaScript. Beside this, it can also be used to reduce the size of HTML files, Cascading Style Sheets, etc.

Tools

· JavaScript code optimizers like JSMin and Packer. These tools preserve conditional comments when they minify the source code of a JavaScript.

· Closure Compiler which is a tool released by Google. This tool can remove dead code, do aggressive naming and function inlining.

· Microsoft Ajax Minifier, Yahoo! YUI Compressor and Pretty Diff that help to minify the source code of CSS files

· MinifyPS which is a PowerShell script that reduces the size of PowerShell scripts and JavaScript files.

Advantages

Reduces file transfers

The main purpose of file transfers is to reduce the size of files. The size of the files can be reduced significantly depending on the size of the original file.

Reduces page load time

Since big files take a lot of time to load, minification can help to reduce the page load time considably. As a result, the bandwidth used to transfer files will also be reduced.

Improves user experience

Nobody likes to wait long for a page to load. Reducing the page load leads to better user experience.

Improved organic search performance

Search engines prefer websites that load fast and promote sites that are liked by users. Since minification helps you to reduce your page load time and improve user experience, your site will be liked by search engines as well.

Less server space required

If your website is large, minimizing the code will mean that you need less server space to host your site.

Node.js is a lean, fast server-side platform which is built on Google Chrome's JavaScript Engine. It was written by Ryan Dahl in 2009 and its latest version available is v0.10.36. The meaning as supplied by its official documentation is as follows.

It is a podium built on Chrome's JavaScript runtime with a lively easy build of fast and scalable network applications. It adopts an event-driven, non-blocking I / O model which makes it lightweight and efficient, and also perfect for data-intensive real-time applications run across different distributed devices.

It is described as a JavaScript runtime environment which is both cross-platform and open – source. It is useful for both servers and desktop applications.The applications are written using JavaScript, and they can run within the Node.js runtime on the following OS X, Microsoft Windows, and Linux.

It also presents a well-equipped library of various JavaScript modules that simplify the development of web applications using the platform to a great extent.

Features of Node.js are as follows:

• Non Blocking and focus is on the Event – All API's of Node.js are asynchronous, ie they are non-blocking. It originally means a Node.js based server will never wait for an API to return the data. The server then moves over to the next API after calling it. It then using notification mechanism of Events of this platform helps the server to get a response from the previous API call.

• Very Fast – Since this platform is fabricated on Google Chrome's V8 JavaScript Engine, its library is very fast in code execution.

• Even though it is Single Threaded yet it is Highly Scalable – This platform utilizes a single threaded model along with event looping. Event mechanism aids the server to reciprocate in a non-blocking way and also makes the server highly scalable averse to the traditional servers which used to create limited threads to handle the requests. It utilizes a program which is single threaded and can arrange service to a much larger number of requests in comparison to the traditional servers like Apache HTTP Server.

• No Buffering – The applications of this platform never buffers any data. These applications simply provide output to the data in chunks.

• License – The license for Node.js was released under the MIT license.

This platform is used by the following Companies in its operations follows: eBay, General Electric, GoDaddy, Microsoft, PayPal, Uber, Wikipins, Yahoo !, and Yammer to name a few.

Following are the area in which Node.js is proves itself as an ideal technological partner.

• Adopts I / O bound Applications

• Data Streaming Applications

• Data Intensive Real-time Applications (DIRT)

• JSON APIs based applications

• Single Page Applications

JavaScript allows you to add interactive elements to and perform scripted functions on Web pages. Adding JavaScript in Dreamweaver 8 is not difficult, and does not require you to know JavaScript programming.

In Dreamweaver 8, JavaScript is a "behavior" and is controlled through the Behaviors panel. You'll use the Behaviors panel when adding JavaScript in Dreamweaver 8 to a Web page you're working with.

To open the Behaviors panel, select Windows> Behaviors. Select the + button to activate a drop-down menu. The Add Behaviors drop down menu contains about two-dozen common JavaScript-controlled functions you may add to a page in Dreamweaver. Common functions like checking browser types and revisions, checking for a plug-in, displaying a Pop-up message, validating a form or going to a URL are examples of JavaScript behaviors you may add.

Each behavior in the Add Behaviors menu has a dialogue box that enables you to specify the actions that should take place when a certain trigger is encountered. A trigger is an action that a visitor to your web site may perform, such as clicking on a link, entering data into a form or mousing over a particular location on the page.

You'll find the Validate Form behavior useful if you collect typed information from your visitors. The Validate Form behavior can use to verify that data entered by a visitor is in the correct format or contains only valid data. Once you have configured the behavior appropriately, select OK.

If the behavior you want to add is not among the built-in JavaScript behaviors, you may select Get More Behaviors. This selection will take you to the Macromedia Dreamweaver Exchange Site. Here you'll find user-created JavaScript behaviors that you may download. One caution: not all behaviors at this location are free of charge, but you'll find that adding new behaviors to your Dreamweaver interface is easy when you visit this site.

You may also change a behavior you have added to Dreamweaver 8. To modify an existing behavior, find the behavior you want to edit in Code View. Select it and it will appear in the list below the Add Behaviors button in the Behaviors panel. From this point, you may modify the order in which events occur, change the event that triggers an action or delete the behavior altogether.

Full stack development is an extensive word that umbrellas various stages of software development such as ‘project management, front-end as well as back-end technologies, database management system, and quality assurance.

Front-end technologies are the outer covers through which you interact with, while the back-end is a server-side technology that (user can’t see in the browser) handles the user authentication, database interactions, logics, server authentication to name a few.

Digging deep, let’s distill down and understand the front-end and back-end technologies on the layers of the type of programming languages/frameworks involved in it.

1. Technologies Encapsulating The Front-end

The most commonly used front-end technologies are:

– HTML/CSS

HTML is the foundation of any website development process. It’s the building block that turns the text into images, tables, and links. The latest version of HTML is HTML5.

– JavaScript

A scripting language used to enhance the look and feel of HTML pages by infusing rich and interactive effects. It is commonly found embedded in HTML code.

– AngularJS

It is a JavaScript-based open-source structural framework built for dynamic web apps, beautiful web interfaces, and large scale/ high-performance applications.

– Node.JS

Node JS is an open-source, server-side platform wrapped around the JavaScript language for building scalable, event-driven applications.

– ReactJS

It is a fast and flexible javascript library maintained by Facebook and Instagram that enables us to efficiently build dynamic user experiences.

– VBScript

Visual Basic Script is a component-based scripting language developed by Microsoft. It enhances wen functionality with lightweight speed.

– JQuery

jQuery is a concise and fast JavaScript library that simplifies the HTML’s client-side scripting and can be used to simplify event handling, HTML document traversing, Ajax interactions and animation for speedy website development.

– Bootstrap

Bootstrap contains HTML- and CSS-based design templates for typography, forms, buttons, navigation and other interface components, as well as optional JavaScript extensions.

Other than this there are other front-end technologies like Ember JS and Material UI as well.

2. Technologies behind Back-End

As discussed in the opening paragraph, back-end or server-side technologies are responsible for how the site works updates and changes. The most hard-hitting back-end programming languages are:

– PHP

Counted as the most popular language for web development, PHP’s syntax is quite similar to C and Java. The classic and popular frameworks for PHP are Zend Framework and Symfony.

– PYTHON

Probably, a simpler syntax than PHP, Python is designed to have a legible code and is well tested. The most popular framework for Python is Django.

– Ruby

Designed to be a fun language, Ruby is often called as a programmer’s best friend. Twitter was built using Ruby. The most popular framework for Ruby is ‘Ruby on Rails’.

– Scala

Designed to be concise, many of Scala’s design decisions are aimed to address criticisms of Java. Scala is an object-oriented and runs on Java platform.

– Node.js (and JavaScript)

Node.js is an open-source, cross-platform Java script runtime environment used for executing JavaScript code server side. It’s best known to build real-time Web APIs.

3. Database Management System

MySQL is the most popular DBMS for websites. The other names in the database field are SQL Server, Oracle or DB2.

4. Quality Assurance

Full stack development also includes quality assurance and testing responsibilities. In this stage, engineers oversee the entire development process, from start to finish and check the security concerns, bugs throughout the program.

This was the breadth and depth of full stack development that comes with a full-time service of full stack developer or full stack Web Development Company. Right from the project analysis, UI UX design, and front and back-end development to Quality Assurance this promising line says it all.

In simpler words, Node.js surpasses other available web applications by replacing the WebSockets with the intensive push technology. Wondering what is so special about it? Before this JavaScript framework came into the big picture, only the client had authority to start the communication. Now, building web applications having two-way real-time connections is absolutely easy with Node.js. Applications built using this JavaScript language allow both client and server to build communication along with exciting important data.

Moreover, this framework leverages javascript that makes the process of devising customized web applications as per the business demands extremely smoother and easier. Read on and know how this JavaScript framework can bring a revolution in the web development field.

Why Is Backend Development Important?
While planning to build a software, developers need to think a lot about the backend technology. The groundwork of the development process depicting the total cost involved and how fast the team can release the software in the market depends on this backend technology.

More strong and powerful backend technology makes sure lower maintenance cost in the longer run. Reliability, scalability and speed of the software also depend on the backend technology. Here, it is easily understandable that backend development is very critical in the software development process.

Now, look at some of the revolutionary changes bought by Node.js in the web development field.

> Lightening Fast
Node.js allows the developers to devise highly scalable and fast network applications that have the capabilities of handling great numbers of simultaneous connections, which have high throughput. Google Chrome's V8 virtual machine can compile as well as execute the JavaScript at the speed of lightning. More interestingly, there is a thread in Node.js that performs all kind of I / O operations in an asynchronous way making the process faster. According to experts, Node.js outperforms the PHP almost by 17% in the terms of handling HTTP requests per second.

> Lightweight
Node.js follows an event-driven architecture, which means every single call and operation is just like a series of the asynchronous callback. Due to this, unlike other popular web application development technologies, it can run on a single thread. Obviously, this process makes this JavaScript language extremely lightweight.

> Smoother Development and Better Performance
In terms of efficiency, the full-stack JavaScript is a force multiplier. The same team can efficiently handle both front-end and backend that leads to improved architecture and consistency.

Moreover, building real-time applications following an agile method is possible using this advanced JavaScript language.

Other than all the above-mentioned points, Node.js offers the freedom to creativity, abundant resources like NPM (Node Package Manager), which is a shared library of modules and tools. Additionally, web applications developed using this web development framework are more scalable.

This JavaScript framework is very popular among the startups. However, big names like Netflix, Paypal, eBay, Microsoft, Uber etc. are also using this feature-rich web development framework.

Advantages

Following are the advantages of using Vue.js technology in web development.

1-Very Small Size

The success of JavaScript framework depends on its size. The smaller the size is, the more it will be used. One of the greatest advantages of this technology is its small size. The size of this framework is 18-21 KB and it takes no time for the user to download and use it. This does not mean that it has low speed due to a small size. Instead, it beats all the bulky frameworks like react.js, Angular.js, and Ember.js.

2-Easy to Understand and Develop Applications

One of the reasons for the popularity of this framework is that it is quite easy to understand. The user can easily add Vue.js to his web project because of its simple structure. Both the small as well as large scales templates can be developed through this framework which saves a lot of time. In case of any problem, the user can easily trace the blocks with errors. All this is because of its simple structure.

3-Simple Integration

This technology is also popular among the web developers because it facilitates them to integrate with the existing applications. This is because it is based on JavaScript framework and can be integrated into other applications built on JavaScript. This means that it is useful for developing new web applications as well as altering the pre-existing applications. This integration is possible because Vue.js has components for everything.

4-Detailed Documentation

Developers always like to use the framework with detailed documentation because it is always easy for them to write their first application. The documentation with Vue is so comprehensive that any user who knows a little about JavaScript and HTML can develop his own application or web page.

5-Flexibility

A great deal of flexibility is another advantage of Vue.js. It allows the user to write his template in HTML file, JavaScript file, and pure JavaScript file using virtual nodes. This flexibility also makes it easy to understand for the developers of React.js, Angular.js, and any other new JavaScript framework. Vue.js has proved a lot beneficial in the development of those simple applications that run directly from browsers.

6-Two-Way Communication

And last but not least, it also facilitates two way communications because of its MVVM architecture which makes it quite easy to handle HTML blocks. In this respect, it looks very close to Angular.js which also speeds up HTML blocks.

In the end, we can say that Vue.js has clear advantages over all the earlier frameworks like Angular.js and React.js. In short, it combines the peculiar features of all the older frameworks.

In simpler words, Node.js surpasses other available web applications by replacing the WebSockets with the extensive push technology. Wondering what is so special about it? Before this JavaScript framework came into the big picture, only the client had authority to start the communication. Now, building web applications having two-way real-time connections is absolutely easy with Node.js. Applications built using this JavaScript language allow both client and server to build communication along with exchanging important data.

Moreover, this framework leverages JavaScript that makes the process of devising customised web applications as per the business demands extremely smoother and easier. Read on and know how this JavaScript framework can bring a revolution in the web development field.

Why Is Backend Development Important?

JavaScript is a “scripting program,” which allows people to make scripts of how their website is going to work. When JavaScript errors happens, it can throw off everything. Understanding how computers work can be a tricky business with all of the computer lingo and whatnot. When people construct their own websites, they use JavaScript to help them do it. JavaScript enables certain website functions such as drop down menus and the like. JavaScript errors can be caused by little things such as a corrupt or broken files. If your registry isn’t working correctly, it can cause a series of problems for you and your computer.

How to Stop Alert Messages

A JavaScript error is the most common error on the internet because JavaScript is used by millions of people. But these errors can become troublesome, overwhelming, and annoying when they keep alerting you about the same thing. One way that you can stop these alerts from popping up all over the place is to simply turn off the alerts.

For Internet Explorer users follow these steps:

1. Select the “Tools” tab at the top of the browser

2. Click “Internet Options” at the end of the list

3. Select the “Advanced” tab

4. Check the box to “Disable Script Bugging”

This will end the messages but remember, it won’t end the error. You must take certain steps to find out the cause and to find a solution.

Clean Up Your PC by Cleaning Up Your Drive

Everywhere you go on the internet is saved in temporary files that your web browser stores. If these files are not cleared out, they can buildup and become corrupt or broken.

To remove these files complete the following:

1. Click “Start”

2. Open “My Computer”

3. Right click on the C: or D: drive

4. Select “Properties”

5. Select “General”

6. And Click “Disk Cleanup”

This will generate a list of files that can be discarded to prevent them from becoming corrupt or broken.

A Clean Registry is Key to a Healthy PC

Your computer’s registry is what keeps your computer going. It is the the brain of your computer. When there is something off in the brain, the outcome is negative. By making sure your registry is up and running, your PC will last a long time. A registry cleaner is the best solution to fixing errors.

JavaScript errors can slow down your PC, cause unwanted and unexpected freeze ups, system crashes, and serious damage to your drive. By making sure that your registry is running fully and is fully functional, you can optimize your PC and keep JavaScript Errors form popping up.

Node.Js is an open source cross platform based on JavaScript. It provides the developers a JavaScript runtime environment to develop new web tools and web applications. All the new developments in the field of web are due to Node.js technology. Since its invention in 2009, many businesses have benefitted a lot by shifting to it. Walmart and LinkedIn are the two top businesses that have moved to Node.js and have increased their customer databases.

Top Reasons to Use It

Every new technology brings some advantages for businesses. Node.js, being the latest technology, has benefitted the developers a lot in web development tools and applications. Following are some of the reasons to use Node.js in Web Development.

1-Speed

The very first and the most important reason to use Node.js is the lightning fast speed it brings. This increased speed is due to V8 engine which is on which the Node.js is based. This V8 engine has the ability to translate JavaScript into local machine codes and increase speed. Another reason for this increased speed is the making of single string instead of multiple strings. This solution is also speedy because it reduces the number of servers required for certain application. LinkedIn and PayPal are the two businesses that have benefitted a lot with its blazing fast speed.

2-JavaScript Universality

The next reason why Node is being used worldwide is the use of JavaScript. JavaScript is recognized all over the world because the codes in JavaScript are same for the servers and the clients. Moreover, almost all the developers know JavaScript and can meet the changing demands of the businesses through getting control on the code.

3-Used as Proxy Server

Use as Proxy Server also makes Node.js the mostly used technology. It fills in the gap if the business has no infrastructure for proxy servers but has to handle diverse administrations requiring different reaction times. This technology can store videos, images, and collect data from different sources because it also uses the same code as the server.

4-Increased Productivity

This technology has also increased the productivity of the businesses by removing the gap between front end and back end groups. No store house exists between them and their solidarity increases productivity.

5-Effective in Making Tools with NPM

Most of the businesses are using this technology because its Node Package Manager (NPM) is super fast, reliable, and consistent. This helps the firms to achieve dependency management easily. The presence of more than 60,000 modules in NPM makes it more beneficial than other computer languages.

6-Better Web Hosting

Web Hosting is one of the largest requirements of the businesses. Due to increasing use of Node.js Web Hosting is also gaining momentum. PaaS (Platform as a Service) providers are allowing the firms and businesses to use it without any problem.

Nowadays, consumers access websites and web applications on a wide variety of devices, operating systems, and browsers. Hence, developers have to focus extensively on website’s user interface (UI) to make it easy to access, use, and navigate. As a robust client-side programming language, JavaScript helps developers to build rich web user interfaces (UIs). The developers can further accelerate web UI designing by using a number of front-end JavaScript frameworks. AngularJS is a widely used front-end JavaScript framework developed and maintained by Google.

Like other open source JavaScript frameworks, AngularJS also helps developers to curtail overall web application development cost. But it accelerates custom web application development by enabling programmers to express various components of a web application by extending HTML syntax. Also, AngularJS updates the web application’s UI each time the backend changes by supporting two-way data binding. The developers can further extend AngularJS by integrating it with various JavaScript libraries. There are also a number of reasons why many web developers prefer AngularJS to other front-end JavaScript frameworks.

Why Most Web Developers Prefer AngularJS to Other Front-end JavaScript Frameworks?

Extends HTML Syntax

In addition to being written in JavaScript, AngularJS is also distributed as a JavaScript file. It can be embedded into a web page directly through the script tag. Also, it allows developers to express various components of a web application by extending HTML with three ng-directives – ng-app, ng-model and ng-bind. The web developers can even use AngularJS expressions to bind AngularJS data to HTML without writing additional code.

Implements MVC Pattern Differently

Model-view-controllers enable developers to simplify development of large web applications by keeping their user interface and business logic separated. But AngularJS implements MVC pattern in a distinct way. The AngularJS team calls the distinct implementation of MVC pattern as model-view-whatever. The model-view-whatever architecture makes it easier for programmers to improve the performance and maintainability of complex web applications.

Supports Two Way Data Binding

In addition to implementing MVC architecture differently, AngularJS also supports two-way data binding. The feature helps developers to synchronize the data between model and view components without putting extra effort. AngularJS automatically updates the web application’s frontend each time its backend changes. As AngularJS synchronizes the model and view automatically, the developers are not required to implement DOM manipulation.

Improves Server Communication

AngularJS reduces web server load significantly by supporting caching. At the same time, the built-in services provided by AngularJS help developers to improve client-server communication. The services further make it easier for web developers to work with various backend systems and solutions. Also, the developers can take advantage of the built-in services to make the data return asynchronously without writing complex code.

Implements Client-Side Form Validation

The web developers can create a variety of forms by combining HTML, CSS and AngularJS. AngularJS further helps developers to implement client-side form validation. It monitors the state of the form as well as individual text fields. It even notifies users about the current state of the form or input fields. The developers can easily validate the form input using standard HTML5 attributes. AngularJS even allow them to write and use custom validation functions.

Keeps the Code Maintainable and Testable

AngularJS helps developers to write readable and maintainable code by extending HTML syntax. In addition to extending existing HTML tags, the developers can use directive to create custom HTML syntax. At the same time, the framework keeps the code testable by allowing programmers to use plan JavaScript objects. The models in AngularJS are also designed as plain JavaScript objects. Hence, the developers can use the framework to write clean, readable, maintainable, and testable code.

Provides a Built-in Dependency Injection Subsystem

Often frontend web developers use dependency injection tools to inject dependency to an object in the most appropriate way and make the objects exchange dependencies seamlessly. AngularJS simplifies dependency injection by providing a built-in dependency injection subsystem. The dependency injection subsystem makes it easier for developers to replace individual components off the web application, along with performing testing.

A Component of MEAN Stack

Many web developers prefer using AngularJS as a key component of MEAN stack along with MangoDB NoSQL database, Express.js and Node.js. As full-stack JavaScript, MEAN enables programmers to write both client-side and server-side code in JavaScript. With more and more enterprises opting for isomorphic applications, AngularJS is being used widely by developers as a component of MEAN stack.

Several AngularJS-based Frameworks

In addition to integrating AngularJS with a number of widely used JavaScript libraries, the web developers also have option to avail several AngularJS-based frameworks – Suave, PrimeNG, QuantumUI, Semantic UI and UI Bootstrap. The UI components provided by these AngularJS-based frameworks make it easier for web developers to build custom web-based user interfaces. Also, these frameworks help developers to create responsive and cross-browser web user interfaces.

Keeps Evolving

As mentioned earlier, AngularJS is maintained by Google along with a community of developers. Hence, it keeps evolving consistently to simplify and speed up web application development. In November, AngularJS 5 was released with a number of new features. The latest version of the JavaScript framework simplifies development of progressive web applications, removes unnecessary code from the application through a build optimizer, and provides a new HttpClient.

On the whole, the features provided by AngularJS help web application developers to build custom web UIs in a short amount of time. But the web developers must remember that AngularJS, like other JavaScript frameworks, has its own pros and cons. They have to integrate AngularJS with other JavaScript libraries and frameworks to accelerate custom web application development. They can still use the latest version of AngularJS to avail a set of new and improved features.
