10 JavaScript Libraries to Enhance and Simplify Development Process

As a web app developer, it is always good to get the assistance from one source or the other. While making use of this assistance does not mean that we lack the wherewithal to do work ourselves, it simply translates into the fact that we can expedite the entire development process and significantly reduce the efforts required to developing these web pages and applications. The beauty of Java Development is that along with being an open source, ‘easy to use’ and ‘developer centric’ language, it also makes available a wide range of JavaScript libraries for the developers to choose from and adequately enhance the potential of their web apps, without much loss of time.

Some of these libraries make it easy for the developers to include various other powerful development technologies, such PHP, Ruby on Rails, and CSS etc. and also help in reducing the inconsistencies in the deployment environment. In this article we have discussed 10 JavaScript libraries which we deemed perfect for multi disciplinary development works. We are hopeful that these libraries will help you significantly improve the quality of the applications that you would be working on.

1. Zebra – A library that contains the complete wealth of rich UI components, Zebra helps in creating desktop like and pretty looking layout. The UI elements are defined in HTML 5 Canvas and CSS provides the color designs and hence it runs on all of the modern day browsers. There is an extent of UI components, which includes menus, form element, tabs, grids, menus and a lot more.

2. Parallel.js – A tiny library that takes care of a wide multitude of processing of the scripting language. It is quick, sturdy and fast and allows the developers to fully capitalize upon the ever growing APIs of web workers.

3. Draggabilly – With the library, the developers get to introduce the drag and drop actions in the user interface of their jQuery. Besides, the entity which is being dragged can be used to feature a container and also allows callbacks to various events such as end move and start. The same can be used to return a position or the location of an item.

4. Howler.js – As an audio supporting library, this is perhaps the best that it can get with JavaScript. The library work with Web Audio API and as a default setting jumps back to HTML 5 Audio should the other one fail. It supports cross browser compatibility by accepting multiple formats, supports caching and plays multiple sound files simultaneously. The sounds can be looped and also can be manipulated accordingly in a fade in or out format.

5. SVG.js – If you need to work around SVG files, manipulate it, develop animations around it etc, this is the script that you have been looking for. As a library, it is extremely light weight (merely 5 Kb) and is filled with amazing and gripping features.

6. Chart.js – Developed on HTML 5 Canvas, it offers 6 brilliant chart types in a standalone app weighing less than 5 Kb. The char types include Polar area, column, bar, radar, pie and line. Developers can customized Charts, borders and fonts and also load the charts with various animations.

7. FPS Meter – If you would like a FPS Meter which is impressively fast and sort of breath taking, your search ends here. And well, talking about the technical prowess, the library quite easily measures frames per second, the total number of milliseconds amidst frames, and the total amount of time (in milliseconds) required to render a frame while using the .tickStart() method.

8. Squel.js – Another resourceful and light weighing JavaScript library, it weaves through various object oriented API rather easily. It can be made to work both on the browser and with nodejs; however we would not recommend browser, since the entire query will be visible. Lastly, it renders complete support to every standardized SQL queries.

9. Packery – In technical terms, Packery provides the bin packing algorithm to the web application. In more human terms, this script fills in the empty gaps in the pages. The library offers both intelligent and organized and organically wild elements. Also, the elements can be stamped in a place, made to fit into an ideal spot or perhaps dragged around as and when needed.

10. Formula.js – with a herd of formulas, this library allows the developers to work on multiple categories such as date and time, logistics, finance and text and a lot more.

This was all about the libraries pertaining of Java development services. For superior and high quality products which perform well in the professionally testing and competitive world, hire Java developers today and profit from their expertise, skills and experience. And now, please do share you inputs about the libraries that we just shared, in the comments section below.

Why it is important to select the right web developer for your website

A website is a valuable asset for every modern business, since the businesses today have to depend on World Wide Web for recognition, advertisement and trading of their products and services. The website developed for a particular organisation should reflect its policy and philosophy. Depending on the type of the business, websites should be designed neatly to make it attractive with rich and meaningful content along with easy navigation system. A good website has the ability to entice a number of visitors, who are stuck to different pages for longer time. In order to develop effective websites, the primary requisite is to select skilled and experienced web developers, who will create the websites according to customers’ need.

Websites developed can be broadly classified into many categories, like business, institutional, news, products, celebrity, media or social websites. Depending on the nature of business, it is important to develop websites that can address all the questions and serves the requirements for the particular niche of customers. How the website designing and development requirement varies from one type of business to another, is described below:

Brick and mortar business:

This has the requirement to bring the customers directly to the physical stores. Websites developed for this kind of business should provide the images of the products along with other relevant information and price tags, which are sold in the stores. It is recommended to organise the products in different categories to help the customers in easy finding of what they were looking for. It is also a good practice to provide the address and contact information of the store along with store hours. Adding a Google map with the store address will immensely help the customer to.

Online business:

Examples of purely click business websites are the sites which sell software, games or eBooks etc. These do not require any physical contact between the seller and the buyer. Developers should develop such websites in a clear and conclusive way. Security should be the primary objective for safe online transaction to achieve customers’ reliability. There should also be proper after-sales service and real-time customer interaction to address their issues.

Institutional websites:

These sites can be for academic institutions, social organisations or any Government or non-Government agencies. The website developer should remember the authority, staffs, distributors, clients and should not forget to convey the missions and visions of the institution. The website should provide vital information about the organisation with photo-slide show or video. Google maps can be provided along with for the ease of finding location.

Social website:

Quality should be most important thing to consider while developing these types of websites. Since, billions of viewers follow the social media sites, and post videos and other contents, it is important to properly maintain these sites. Nobody cares who developed these data centric sites and how they work. So a social media website should not talk much about its owners and staffs. These websites are database driven and nobody can predict how large they can be. Ease of navigation should be prioritised along with the maintenance of privacy of every single user. Hacking is a big problem for this type of websites, so the developers have to be much cautious about the security. Generally social media sites involve a huge team of developers and other professional to be designed, developed, tested and maintained for longer time. Finally it is important to develop the social media sites in a way, so that they can be accessed from any browser or any operating system from PCs or mobile devices.

It is quite clear that different types of websites have different requirements to serve wide range of target audience. It is important to select right web developers for serving the purpose of the website with error-free functionality and aesthetically pleasing quality.

How to perform testing without proper Spec or documentation

QA testing professionals will come across various scenarios in day to day life, some of them can be tough to cope up with, while some issues can be handled with years of expertise. Software quality assurance and testing are very critical in nature and requires eye to detail.

Let us take a scenario, where there is no Functional Spec or documents related to the system is available. Further to add misery, you come to know that the developer who wrote the code is no longer working with the company, but you have the system and need to test.

Well, sometimes QA testing experts face such situations when they need to perform “Testing in the Dark” means there is no Functional Spec or document related to the application. But testing without information of the requirements is same like placing the cart before the horse. In such cases performing exploratory testing is one of the best process to go further. While performing exploratory testing tester should understand the application by spending some time, carry out a detailed study of the application, poke the areas which they think are more sensitive and bug prone and then make out a list of features and functionalities that are critical and note down the possible testable scenarios.

Whenever such condition occurs, the testers should do the best to manage the entire testing process efficiently and effectively. Personal experience and instinct plays a very important role to find issues as well as to hit the application hard.  One should also use their prior Knowledge gained from previous projects and also follow metrics from previous similar projects which could be beneficial. There are also other techniques like black box testing, Blind testing, Adhoc testing and error guessing. One can take help of experienced person in that domain.

Testing of a system which do not contain any specifications or documents, you would only observe what a developer want you to observe and not from the customer perspective.

In such case, prior to system testing, first of all we should ask few questions to ourselves.

1) What type of testing is required on the system-unit /functional /performance /regression etc.

2) Is it new project or coming for maintenance?

3) Is the application is on Staging or Production?

4) Is there any domain expert available?

5) Is there is any business expert available?

6) Is any end user available?

7) Are there any known high risk areas?

8) Is manual or automation testing is required for testing?

All these questions would help us to identify the main key areas of testing and ignorable areas of testing. Once you get to know the key areas then you can start with following testing approach.

Being a Software quality assurance and testing professional, the first step would be to understand the application, to understand its functionality and outcomes. So what we should try is “Focused Exploratory testing”- to identify every section in the application or system and identify the functionality of the application.

One of the best option we have Smoke Testing  to make sure that there is no blocking issue in the system and since it only to certify the piece or build.

“Monkey testing “would also be helpful, as it is all about Adhoc testing or negative testing, to identify the break point of the application and threshold limit of the application.

Summary:

Well, sometimes QA testing experts face such situations when they need to perform “Testing in the Dark” means there is no Functional Spec or document related to the application. Software quality assurance and testing are very critical in nature and requires eye to detail.
