5 Tell-Tale Signs You Need to Get a New JavaScript Grid

A Data Grid is a user interface element that you’ve most likely seen before. It’s a table-based component that shows data in a table format. Each data item is represented as a row with columns indicating the field of items.  Grids have been in functionality for a very extended period of time, especially on desktops, but they’re becoming increasingly ubiquitous in the UI of web apps. Every computer that takes part in a data grid must execute a certain software.  The program serves as the system’s administrator and handles numerous grid-based activities.  To be more specific, the software divides up the work into smaller chunks and distributes it across the computers, allowing everyone to work on their projects simultaneously.  The results of sub-projects are collected and combined to fulfill a larger-scale project after their completion.  It is possible to exchange information about which subtasks each computer is currently working on and how to consolidate and deliver results thanks to the software.

In this article, we will go through the various benefits and features Ext JS offers as a JavaScript grid, and the drawbacks it can cause in your projects.  We will also highlight the ways to optimize Ext JS  to improve performance.

Why Should You Use Sencha Ext JS?

Extended JavaScript is abbreviated as ExtJS. It is a Sencha JavaScript framework based on Yahoo User Interface (YUI). It’s essentially a modern-looking desktop application development platform.  This tutorial will deal with problems with Ext JS grid performance, its benefits, limitations, and methods for improving your website performance through the Ext JS grid we are using.

Because of the computational complexities, very high costs are associated with new implementations of grids that most firms and software engineers today choose for existing system solution approaches.  So It’s no surprise that many third-party JS data grids are available in both free and premium editions.  However, choosing which one to utilize can be difficult in and of itself. So how do you go about doing that?

After ensuring that a grid fits the features and performance criteria, which can be easily analyzed by Sencha’s own JS Grid Performance Analyzer, developers are more likely to use the widget in their applications if it comes with detailed documentation that lays down all functionalities and provides examples.

What Are the Useful Features of Ext JS?

The latest version of Ext JS provides the following features:

• Grids, pivot grids, forms, charts, and trees are among the rich UI widgets available that can also be customized.
• There exists compatibility of code between new and previous versions of Ext JS.
• A versatile tool for layout management aids in the organization of data and a display of that content and data across a variety of browsers on various devices having different sized screens.
• The advanced data package separates the data layer from that of the widgets of UI.  The data package enables data gathering on the client-side using models presenting high functionality with capabilities like being able to sort and filter through data.
• Protocol agnostic can obtain information from any source at the back end regardless of the protocol.
• Themes that can be altered.  Multiple theme options are provided that are out of the box for widgets belonging to Ext JS, consistent throughout platforms.

What Interesting Benefits Can You Acquire from Ext JS?

1. Development across platforms for current and older browsers on computers, tablets, and smartphones is simplified.
2. Integration of IDE plugins into corporate development environments increases team productivity.
3. The cost of developing an application on the web observes a significant reduction.
4. It gives teams the tools to develop applications that users will love. 
5. Widgets for creating a robust UI are provided. 
6. The code is easy to understand since it adheres to the MVC design.

What Limitations Does Ext JS Pose?

Is the size of your library too large?

The Ext JS’s library’s size is roughly 500 KB, which slows down the application’s initial loading time and makes it less responsive.

Is your HTML full of tags that are too complex?

HTML is jam-packed with tags, making it tough to understand and troubleshoot.

How expensive are rendering components?

Components for rendering might be somewhat pricey. Increasing the size of the DOM makes it more difficult for browsers to carry out the required actions to alter it.

Are there poor designs and memory leaks?

Because Ext produces and manipulates a large number of DOM objects, users may encounter performance difficulties due to inefficient design, memory leaks, and other flaws.

What Do You Do to Optimize ExtJS Performance?

• Improve page load speed by optimizing pictures.
• The larger the image, the more time it takes to load. You should save your photograph in an appropriate format.  Your website’s page load time will be reduced if you experiment with the ideal parameters for each image file type, such as quality, palette size, etc.
• Make your design mobile-friendly.
• Those who use mobile devices have different goals than those who use desktop computers, and they prefer to consume information in smaller, more manageable chunks.  It’s a reasonably simple technique to get a competitive advantage because many mobile consumers are having issues loading their websites.
• Make your code compact by minifying your CSS, HTML, and Javascript.
• To speed up the loading time of your website, you must remove unnecessary spaces and line breaks from your code, as well as indentation.  This can be accomplished by using minify tools to compress your file.
• Make an informed decision on your framework.
  While there are plenty of simple-to-use responsive frameworks available, numerous plugins, CSS, SASS, Javascript, and ready-to-use templates will harm the speed of your website, so you should avoid using it if you want to speed it up.  Think about implementing more modular mobile-first frameworks.
• To improve page loading speed, make CSS and JavaScript external.
• Using external files will generally speed up page loading because the browser caches JavaScript and CSS files.
• If you want to use CSS in a web page, put it in the HEAD element instead.  This gives the impression that the page is loading faster, and can do so gradually.  Relocate the scripts to the bottom of the page with JavaScript.

Over the last two decades, the amount of data generated has increased exponentially.  As a result, new JavaScript data grid components have evolved to handle the presentation and analysis of these huge volumes of data.  As a result, many data grid products on the market today boast greater capabilities for displaying and managing analysis.  But how many of them can stand up to a true performance test when it comes to “Big Data”?

Sencha’s performance evaluation was based on how a real-world end-user would utilize the grid, and they put those data grids to the test that are most popular in the market these days.  According to their test results, the Ext JS data grid outperformed most competitors on scrolling performance when tested with medium to large datasets.  By making the improvements detailed on this website.  We can deal with the limitations of ExtJS.  Don’t forget about the user experience element.  We might often be guilty of providing attractive graphics and intricate design at the expense of page load speed.  It’s all about having the upper hand.
