10 Compelling Reasons Why You Need Javascript Grid Library

In modern web applications, rendering a large amount of data in tabular format is often an essential requirement. Javascript Grids help web developers efficiently load the data set in rows and columns without significantly affecting the page load speed. 

Nowadays, several JavaScript grid libraries are available on the market, enabling developers to integrate many useful and complex operations on tabular data. For example, web developers can use the Sencha Ext Js grid library to provide consumers with useful grid operations like scrolling, sorting, grouping, and filtering.

If you are a web developer who hasn’t decided on using a Javascript grid library in your projects, this article will show you why you need to use a Javascript grid library.

One of the important reasons you should integrate a grid into your application is to provide a more user-friendly and positive experience to the end-user. When it comes to grid operations like sorting and filtering, responsiveness is important. Because if the user has to wait a long time to get the results, frustration can occur, which negatively affects your companies’ image. Javascript grid libraries consist of everything you need to build highly user-friendly and responsive grids. Grid libraries have been designed to provide better performance in every operation it supports to get the required data as efficiently as possible.

When there are many data loaded on one page, the users need to scroll through the page to view the entire data set. Grid libraries can make this scrolling speed efficient where users will hardly experience a delay in loading the data. One example is the Ext JS Grid Library has a scrolling speed that takes seconds. Also, most grid operations like filtering sorting can make efficient according to the amount of data you have to manipulate. 

Building a grid on your own can be challenging, especially if your project has a tight schedule to complete. If you want to avoid writing code as much as possible and speed up your development, you must use a Javascript grid library.


A grid library provides different reusable components for building a high-performing grid within a short period. You will have a large feature set from basic to advanced to handle millions of data sets within seconds. External JS Grid library, for example, enables users to use Ext JS Kitchen sink for re-usable components with Grid components. Some components users just have to drag and drop without writing code. This low-code development makes developers’ lives easier and helps them be more productive. 


When you integrate a grid into your application, it is important to give attention to its look and feel. Because users tend to engage in UI components that are eye-catching and consistent throughout the application, developing a grid and making your themes from scratch can consume a significant amount of time. JavaScript grid libraries help you easily apply different themes to your grid to enhance its appearance. Most libraries have a collection of predefined themes which you can directly apply. 

Also, sometimes you may require to build themes specific to your business requirements. Most grid libraries enable users to build custom themes and use them throughout the application to make the grid appearance consistent. For example, you can use Sencha Themer with Ext JS Grid library to build customized themes for your grid without writing any code.

In today’s web applications, visualizing data set to understand the importance of the data set is a useful functionality most web developers aim to provide to the end-user. Most Javascript grid libraries can visualize the data using bar graphs, line charts, pie charts, etc.

Also, grid libraries offer functions for data analytics and insights. For example, you can make pivot tables using the Ext Js grid library. Using pivot tables, you can show summaries of information of table columns and then use those summaries to show the trend and patterns of the data to the user integrating widget charts within the table itself. This functionality is particularly useful if your consumers are executives or managers who are often required to present data summaries and derive insights for drawing conclusions. 

Grid libraries are not limited to the existing functionalities that come by defaults. There are plenty of plugins you can utilize with them to add extra functionalities. For example, Ext Js Grid library offers users extra plugins such as Ext. Toolbar. Paging to add paging toolbar, Ext. Grid.feature.Summary plugin for adding more summaries of information at the bottom of your table, Ext.grid.feature.Grouping for grouping rows that have similar values for a particular column. These external plugins help developers customize the grid as they want without altering your existing code and writing any extra code. 


When you build user interfaces, accessibility support is important to consider to provide equivalent access to differently-abled users. The same thing applies when building grids. If you use a Javascript grid library, you do not have to worry about supporting it yourself as they already have accessibility support.

Modern web applications require Javascript grid libraries to design and develop high-performing grids that can load millions of data in seconds. There are plenty of grid libraries available, but developers may not know why they should use one. This article described ten reasons developers need to use a grid library instead of writing everything from scratch. The responsiveness you can offer is the most important reason, and there are plenty of other reasons you should make sure to use it in your applications.
