On April 12, 2022, we held the third Virtual SenchaCon, featuring a number of discussions on a wide array of topics, ranging from Sencha’s latest product GRUI to Serverless for JS Devs.The company has been organizing the conference virtually since the beginning of the pandemic in 2020. Although last year’s con was held on two subsequent days, this year, the con was wrapped up in one day. A lot of things were discussed in these conferences, but one of the most vital sessions was conducted by Jason Cline, CTO of Celestial System. He defined in detail every aspect of Sencha’s latest product GRUI. The Sencha Con kicked off with an opening keynote from Kegan Blumenthal, General Manager of Sencha, himself. Let’s see what he said. Keynote Highlights Kegan Blumenthal, General Manager of Sencha, along with Sarina Dupont, and Eric Romoff, led the first session of SenchaCon 2022. In this session, Kegan shared the keynote and themes of the SenchaCon. Then, Sarina, Director, Product Management described the future road map, and Eric, Chief of Staff at Sencha, introduced us to the latest product of Sencha, which is GRUI. So let’s discuss the conference in more detail. Sencha Ext JS Explained by Kegan Kegan started the conference by describing the growth of Sencha over the past year. The company has expanded its community in that time and has also been recognized as a leader of G2 in the Across Community and User Ratings categories. According to Kegan, one of the key themes for Sencha in the year 2022 is to aim for low codes and high performance using low-code tooling. Kegan said, “Low code enables enterprises to create better experiences for the users with a low-code approach.” He also stated that the low-code approach would enable enterprises to create and deliver apps in record time. Low code also has the Architect feature, which is customizable and gives users drag-and-drop features. And using this, users can develop applications 20 times faster. The other key theme for Sencha 2022 was to focus more on the React community. The new grid component of Sencha, which is GRUI, is based on the XJS component and built from React. Kegan also shared the other solutions that support React, such as Froala, which is a rich-text editor; FusionCharts, a charting library; and Filestack, a file upload API. Later Kegan gave an overview of the evolution of JavaScript tooling. He emphasized that the Ext JS grid component is the number-one focus of Sencha. Sencha is doubling its efforts on the Ext JS data grid component to make it better. According to Kegan, the Ext JS UI library contains all the tools that users need to build an enterprise-level application. Considering the fact that app security has become a major concern among developers, Ext JS provides all the components built in house, reducing the scope for dependencies and vulnerabilities and thus making it a safer solution for app development. Other important news Kegan shared during the conference was that Ext JS OEM License is now rebranded as Ext JS Hub License. And at the end of his part of the conference, Kegan briefed attendees about the diversity of industries in which Sencha is growing, some Sencha case studies from the last year, a few white papers that Sencha published in […]

The heat map is a graphical representation of a numerical dataset which is a fantastic method for analyzing the frequency of a data set. It brings different color indications from warm to cool in specific x and y-axis areas. That means more significant interactions are represented using warmer colors in the area, while colder colors represent lower user interactions. The following graph shows a sample D3 heat map. A heat map represents the relationship between two variables. By analyzing cell colors, you can determine the patterns between both variables. Variables can be any data type since we consider values as categorical numeric values or labels. The heat map shows the row(x-axis)/ column(y-axis)/ value when moving the mouse cursor on sections. What are the different types of heat maps and different things you can do with them? We can see different types of heat maps used in the different industries, such as website heat maps, geographical heat maps, stock market analysis heat maps, heat maps used in financial services and sports, and more. The key benefit of any type of heat map is it converts complex numerical datasets into a simplified, understandable visual graph and helps decision making. What are website heat maps? Website heat maps help product managers, product owners, and website owners determine how users interact with their website, make critical decisions, and find answers to critical questions. Suppose you have a website having considerable user traffic daily. You can perform activities such as, Identify user behaviors, interactions and evaluate user interests on the website Identify ignored things by users on the website Identify issues across different devices Determine if users are reaching an important content or not Hence the business can improve the website by tracking user behaviors and discovering actionable scenes and activities. Website heat maps are used in online stores sites, media services such as Netflix, travel and hotel sites, eCommerce sites, etc. heat maps support measuring a website’s performance, understanding guests’ thinking, and determining friction scopes by recognizing dead clicks and redundant links. For example, Netflix uses heat maps to determine the user’s streaming interests, most commonly watched movies and tv shows, identify most visited categories such as action, horror, Hindi, cartoon, etc. and personalize the user experience according to the user on their site. Following is a sample heat map generated for Netflix. Image source: GigaOm   How are heat maps used in the stock market and financial services? Heat maps are used in stock markets to make future decisions, such as identifying trending stocks in a certain period, identifying what shares to buy and what is the best selling price for a specific stock, and identifying the best time to invest by determining whether the overall market has a bullish or bearish trend. From a financial perspective, we can use heat maps to visualize action items in companies such as, Interest rate fluctuation and fixed deposit placement ratio in banks How do companies’ investments in different assets such as blockchain, fixed deposits, treasury bonds, debentures, and share market bring ROI to the company? Identify and compare the annual budget allocations with past years. These are only a few use cases of heat maps used in the financial industry. Usually, most organizations use heat maps for future predictions, to understand how their business behaves […]

Nowadays, most web developers prefer to use frameworks for their developments as they provide a more reliable and efficient way to build modern JavaScript-based web applications. However, it will be best if you can find the most suitable and user-friendly framework before starting. Sencha Ext JS is one of the best JS frameworks you can find on the internet. In this post, let’s discuss ten signs of a good JS framework. Is It Easy to Set Up and Use? The framework you select should be easy to set up and use. Another essential fact is that the framework should be cross-platform compatible as you have to share your code across multiple devices and developers who use different operating systems. Furthermore, if the framework has documentation, it is easy for developers to go through and refer to when they struggle with something or need to find out new features. Sencha Ext JS is easy to set up and use. This framework is appropriate for JavaScript-based development as it supports numerous popular libraries such as Angular, React, and Next.js. Does Your JS Framework Auto-Generate Code? Whatever the JS library you use, you have to implement different components using HTML5. In that case, developers have to put some effort into constructing HTML forms, components such as login, registration, dashboards, and contact pages. However, auto-generating code instead of coding manually will save time in the development phase and reduce human errors. Sencha provides that feature for busy developers. As the best JS framework, Sencha comes with a visual app builder called Sencha Architect. It lets you generate excellent user interfaces by dragging and dropping different UI components. How do I Debug the JS Code? Developers have to put considerable effort into debugging during the development and maintenance phases of SDLC. The reason is that you have to analyze the code step by step once you overcome an incident or issue. That process will be fast and effective if the JS framework you use supports debugging. Sencha Inspector provides debugging and troubleshooting features in the ExtJS framework. It equips smart debugging features, such as direct access to classes, objects, and components. Thus, you can analyze the JS code for issues and identify problems such as over nesting components and the number of layouts required to operate the JS app in optimal performance. Furthermore, you can use Sencha Inspector to perform unit testing and end-to-end testing of apps built using ExtAngular, Angular, and ExtReact on different operating systems and cross-browser platforms. Can I Share Code Snippets? You will have to share code snippets with your colleagues and other developers during the implementation of your JavaScript application. So developers use different techniques to share code, such as sharing code via GitHub or GitLab and pair programming. Now you can easily create & share code using Sencha Fiddle, which is an online platform. You don’t have to set up anything locally. Yet it brings you the look and feels of a local development environment. It also supports all the browsers and works on any operating system. You have to log in with Sencha forum user credentials and share the code using the fiddle URL to share code snippets. Can You Use GraphQL with Your JS Framework? Today most developers use GraphQL to control the data required through an […]

Vue JS and React are both leading-edge competing technologies popular for front end development. Vue JS is a popular Javascript framework for creating simple and clean user interfaces along with single page applications. It supports a virtual DOM with two-way binding. It also has a progressive design, allowing you to migrate your existing projects one feature at a time. The React library is also very popular amongst developers. It supports a virtual DOM with two-way data bindings. Following a component based approach, React enables you to rapidly build complex web apps. Are you a developer at crossroads, trying to decide whether to use Vue or React for your next project? To make this decision easy for you, we have compiled a guide with pros and cons of both Vue and React. Continue reading to find out various aspects of application development when using Vue JS vs React, both supporting the integration of Sencha ExtWebComponents as described in the end. What is the Core Difference Between Vue and React? When it comes to the core difference, Vue is a complete standalone Javascript framework with its first release made in 2014. On the other hand, React is a Javascript library, first released in 2013 and has to be used in conjunction with other libraries. They are both open source. How are Components Built in Vue JS vs React? One of the most significant distinctions between Vue JS and React is the syntax, and the way the view layer is developed and components are built. In Vue JS, developers use HTML templates to build the components. The view layer uses HTML templates by default but Vue developers also have the freedom to use JSX. On the other hand, in React there is only one option and that is JSX. JSX is used to express both HTML and CSS using Javascript. JSX stands for Javascript XML and it is a Javascript syntax extension. JSX requires a tool/compiler such as the Babel transpiler, for conversion of code that can be to be further processed by a web browser. Which is Better, HTML Templates or JSX? If you use HTML templates, there will be a clear separation of concerns into HTML, CSS and JS. The view will be separate from the logic. JSX on the other hand, contains both HTML and CSS in one, allowing developers to build self contained and standalone UI components that hold everything from styles and rendering instructions to logic. At the end of the day, it’s all a matter of personal choice. For novice developers HTML templates are easier to learn and work with. They have a simpler design and cleaner code. However, expert developers find JSX a very powerful and flexible tool for building components. How Does the Performance of Vue JS and React Compare? Benchmarking experiments have shown that Vue and React have almost the same speed of execution for most tasks, with Vue being slightly better on most metrics. Vue has more built-in smart optimizations, while React does not have any. This gives Vue an edge over React. However, we have to keep in mind that the final speed and performance of an app heavily depends upon the coding style, application size and optimization. What About Mobile App Development in Vue JS vs React? For mobile app development, […]

  As a web application developer, you must have a deep understanding of UI components. You need to have a clear idea about how users interact with them. It will help you to develop user-friendly web applications. There are various JavaScript libraries and frameworks that can help you build an attractive user interface. However, which is the best one? Does it enable you to create a beautiful interface for your app easily? In this post, you will find all the details. What are UI components? UI components are the most integral parts of a web application. They consist of all the app’s styles and components, such as buttons, input fields, icons, text, etc. They are the core building blocks for all applications. UI components are responsible for interactions between the user and the application. They facilitate an effective user experience, and they allow the users to navigate through the application easily. Also, the UI components help them to efficiently perform various functions, like adding/editing information, filtering data, selecting a date on the calendar, etc. Why should you use UI components? Quickly create the user interface of your web application Reduce code duplication by using reusable components Save development time and money Easily update the UI when required How can I easily create UI components for my JavaScript application? You can easily create UI components for your JavaScript web application using Sencha Ext JS. It is the most comprehensive framework for building data-intensive apps for all modern devices. The UI of Ext JS applications is made up of widgets. They are known as components, and they are subclasses of the Ext.Component class. You can easily extend them to create a customized component for your web application. How can Sencha Ext JS help me in quickly creating UI components? Sencha Ext JS allows you to use reusable code. As a result, you can easily create UI components. Also, it doesn’t require you to get involved with a lot of coding. You can create UI components with just a few lines of code. Let’s take a look at some practical examples. How can I quickly create a calendar for scheduling events? The Ext JS calendar is a powerful UI component for creating custom calendars. It allows you to use the date and event data, just like Google Calendar. Here is an example: The calendar allows you to schedule your work and personal events easily. It comes with a minimalistic design. To create it, you have to follow these steps: 1. First, you need to define a new custom class, called KitchenSink.view.calendar.Month. Then you have to extend Ext.panel.Panel. Also, you need to define the type of UI component, which is calendar-month-view. Ext.define(‘KitchenSink.view.calendar.Month’, {    extend: ‘Ext.panel.Panel’,     xtype: ‘calendar-month-view’, 2. Then you have to add this code:    requires: [        ‘KitchenSink.data.calendar.Month’,        ‘Ext.calendar.panel.Month’,        ‘Ext.calendar.List’    ],    width: 1000,     height: 600, 3. Next, you have to create the viewModel.    viewModel: {        data: {            value: Ext.Date.getFirstDateOfMonth(new Date())        },        stores: {            calStore: {                type: ‘calendar-calendars’,                autoLoad: true,                proxy: {                    type: ‘ajax’,                    url: ‘/KitchenSink/CalendarMonth’                }            }        }     }, 4. Now, you have to specify the layout, bind, and titleAlign fields.    layout: ‘border’,    bind: {        title: ‘{value:date(“M Y”)}’    […]

JavaScript is everywhere. It is used on millions of websites and isn’t going away anytime soon. This language is no longer restricted to your web browser as it’s also appropriate for server-side apps. When it comes to showing data, the Grid is one of the most fundamental and helpful JavaScript components. It is a common yet essential technology used by developers to display enormous data sets and, more significantly, to allow users to browse, sort, and interact with them. JavaScript Grids are a tool that allows developers to modernize and speed corporate processes by making it easier for their users to work with data. JS Grid enables us to present vast amounts of data without stuttering or freezing. They also help us save a lot of time when it comes to data management. This article will discuss 5 examples of successful JS Grid so that you can understand this tool better. Why are Data Grids Important?   Data grids are required in online applications that display a large amount of data, such as live reports, tracking statistics, etc. The following are some of the reasons why you should use a data grid in your next project: Data grids boost your application’s performance. Because most open source data grid libraries are small and light, they don’t have a lot of overhead. Virtual scrolling is also available in most libraries, improving user experience while scrolling through enormous amounts of material. Filtering, sorting, and pagination are characteristics of data grids that make it easier to navigate enormous databases. What is the Importance of Sencha Ext JS? Sencha Ext JS is a JavaScript framework that is used for creating data-intensive, cross-platform online and mobile applications for all modern devices. This JS framework comes with over 140 high-performance UI components that have been pre-integrated and tested. Ext JS is the most comprehensive collection of high-performance, customizable UI widgets in the industry, including HTML5 grids, lists, menus, panels, toolbars, trees, forms, windows, and more. As previously stated, the focus of this article will be on JS grids. Why is Ext JS Grid the Best in the Market? The Ext JS grid is an extremely useful component with its comprehensive functionality and many extensions. It simplifies app design since it does not rely on third-party libraries. Built-in Ext JS UI components like dropdown menus, grouping data, and other fascinating add-on functionalities also assist with data organization. In Ext JS, the grid uses buffered grid rendering. Users can use this option to browse thousands of data points without incurring the performance penalties of bringing them all into the DOM at once. Column locking is another handy feature of Ext JS. You can enable automatic locking by setting the column’s ‘locked’ settings to ‘true’ or by setting ‘enable locking’ to ‘true.’ Furthermore, programmers can embed components inside grid cells in Ext JS using the WidgetColumn class. For adding a Widget Column to your page, you simply have to set the xtype of the column to “widgetcolumn.” Ext has several helpful plugins. For instance, the Row Expander plugin adds an “expander” column to each row, allowing the user to reveal or hide the body of the row. Because users can minimize, increase, or hide columns based on their needs, this feature is critical. Another advantage of this feature is that […]

Angular Material is a reusable library stocked with UI components modeled after the arrival of Google Material Design. It ensures that each element has been thoroughly tested for performance and reliability standards. Angular Material functions as a framework based on the fundamentals of web design, powering up-to-date browser portability and device independence. The Angular Material Component contains all the default assets of a website to be prepared before it’s ready to deploy on a JS environment. Not only are the building blocks released regularly, but the framework also has many callable API methods to access. By providing the user with well-maintained documentation and custom CSS styling, they will be able to launch a working application in due time. What Makes Angular Material Components Convenient for Development?  It takes more than just mashing together templates to build a collection of Angular Component tools capable of designing software that considers the user experience. A component library should, at its very core, extend the existing functionality of the Angular framework. To be specific, the goal has always been to automate repetitive tasks in hopes of saving time on code maintenance. This Angular library employs the following API-supported templates:  Advanced from fields with autocomplete and date pickers A variety of navbars, touch-swipe, and speed dial navigation Grid layouts including data tables, organized tabs, and collapsable lists Spreadsheets, rich text editors, charts, and progress bars for business purposes Interactive buttons, menus, checkboxes, lists, portals, etc.  Angular Material offers many use cases, such as managing large data sets, creating seamless user interfaces, and consistently executing projects with version control. Rather than rewrite code for individual functions, developers can enjoy the perks of a responsive front-end for implementing custom code into their demos. The key advantages are: Faster development speeds. An easier learning curve. Shortcuts for debugging scripts. Cross-browser support on all components. Another key selling point is using schematics to generate toolbars and menus that make up the dashboard—while entirely optional, customizing your Angular Material theme with “mixins” can transform a bland site into a work of art for your viewers. Under the Guides tab are some resources to set up: For one, you could install a CDK stepper that directs the user from one step to the next. And to change the font, typography settings are easy to configure. The possibilities are nearly endless if you know exactly what components fit together on each web page. Examples of top Angular libraries include MaterialPro Angular 9, NGX-Bootstrap, Prime NG, and Angular Fire 2, which you might’ve heard of. Why does Angular Need to Install a Component Dev Kit (CDK) Package?  The CDK package contains schematics that are available over the Angular CLI. This library assigns a set of replicable behaviors to each building block, allowing Angular developers to reuse code logic whenever they need to add a common interaction pattern.  It is certainly a time-saving collection, especially when tasked with positioning overlays, creating data tables, managing scroll behavior, or presenting content in a hierarchy.  On Angular Material, properties are defined in the Overview tab. Every method has a tutorial on implementing it, and snippets are available for direct copy and pasting.  For instance, if you want to configure site accessibility, you could control the FocusMonitor service, which identifies changes in an element’s focus state. Then it indicates whether the focus […]
