A Beginner’s Guide To JavaScript Grid Libraries

Developer-friendly JavaScript grid libraries are key in web development. They help manage large amounts of data faster and easier. These libraries offer features like sorting, filtering, and on-the-fly updates. With the rise of data-intensive applications, these libraries are becoming even more popular.

Grids are more than just tables. They combine data management and visualization. This improves usability. Grids can handle massive amounts of data and complex computations. They also manage multidimensional data. Libraries like Sencha ExtJS, AG Grid, and DataTables extend grids beyond simple tables.

This guide covers basic concepts of JavaScript grid libraries. You will learn what a JavaScript grid is and its key features. You will also understand how human analysis, user experience, and grid code structure affect the grid’s effectiveness. Let’s begin.

What is a JS Grid?

A JavaScript (JS) grid is an interactive, live data table. It adds structure to a web application. Unlike basic HTML tables, JS grids manage large datasets with more features.

With JS grids, users can quickly access, scroll, organize, and sort data. This greatly improves the user experience.

Two main components make up a JS grid: Ext.data.Store and Ext.grid.Panel. Ext.data.Store manages the data source. Ext.grid.Panel displays the data in a table format.

Here’s a simple grid implementation in Ext JS:

Ext.create('Ext.grid.Panel', {
    title: 'Example Grid',
    store: myDataStore, // Data source reference
    columns: [
        { text: 'Name', dataIndex: 'name', flex: 1 },
        { text: 'Age', dataIndex: 'age', width: 100 },
    ],
    height: 300,
    width: 500,
    renderTo: Ext.getBody()
});

This code creates a grid with two columns: “Name” and “Age.” Developers can build on this by adding features like pagination, cell editing, or exporting to Excel.

How Do You Choose the Best JS Grid Libraries?

There are several aspects to consider:

Understand Your Requirements

First, identify what you need. Do you require pagination, sorting, and filtering capabilities? Or do you want a simple grid? If your libraries are larger and more complex, mention that. Knowing this limits your options.

Evaluate Performance

Performance is key. This is especially true for applications with large data. Virtual scrolling or pagination can help achieve this.

Feature Set

Key features should include basic column operations. These include selection, filtering, and cell focus or editing. Other important features might be drag functionality and cell rendering.

Ease of Use and Documentation

What Are the Components of JS Grids?

JS grids are made up of two key components: Ext.data.Store and Ext.grid.Panel. These components work together to manage tables.

Ext.data.Store

The Ext.data.Store holds the grid data and defines the visible columns. It fetches inline data and loads data when needed. The store can handle complex data sets and supports filtering and sorting, making it ideal for sophisticated applications.
Here’s how you create a store:

Ext.create('Ext.data.Store', {
    storeId: "myEmployeeInfo",
    fields: ['employeeid', 'name'],
    data: [
        { 'employeeid': '1', "name": "Sam" },
        { 'employeeid': '2', "name": "Sara" }
    ]
});

This store holds employee data with two fields: employeeid and name.

Ext.grid.Panel

The Ext.grid.Panel forms the visual layer of JS grids. It displays the data in a table format. It is flexible and easy to use.
Here’s how to create a grid:

var cols = [
    { text: 'employeeid', dataIndex: 'employeeid', flex: 1 },
    { text: 'name', dataIndex: 'name', flex: 1 }
];
 
var grid = Ext.create('Ext.grid.Grid', {
    title: 'Employees',
    store: "myEmployeeInfo",
    columns: cols,
    layout: 'fit',
    renderTo: document.body,
    width: '100%',
    height: 500
});

This code creates a grid with columns for employeeid and name. The data comes from the store and is displayed correctly in the grid.

What are the Properties of JS Grids?

JavaScript grids are powerful tools for displaying data in table form. Here are some important characteristics:

Collapsible

This feature allows grids to shrink and expand. Set collapsible: true in the grid’s configuration. Users can collapse the grid when not needed and expand it later. This is useful for saving space on dashboards.

Sorting

Sorting data arrays is often necessary. Enable sorting by using sortable: true in the column configuration. Users can reorder items, such as prices, from low to high or vice versa. Sorting is enabled by default.

Column Hidden

This feature controls column visibility. Set hideable: true in the column configuration. Users can hide or show columns as needed. For example, users can hide salary information, as it may be sensitive.

Column Resizing

This feature allows an end-user to change the width of the columns in a grid. It can be enabled by setting enableColumnResize: true. It is useful when dealing with data whose values are larger than the previously defined datatypes, such as long names or very long descriptions.

Renderer

Rendering means defining how the data in a grid will look. For instance, if a column has dates, one can mask them to show as “MM/DD/YYYY.” This makes the data much easier to read.

Column Dragging

This property allows columns to be moved around. Add enableColumnMove: true, and the user can drag and drop columns. This enhances user interaction and flexibility.

What Are the Benefits of Having Basic Data Analysis Skills for JS Grids?

It is necessary to have basic data analysis skills before working with JavaScript grids. JS grids are powerful tools for data management and display in web applications. Understanding how these grids work helps in using them effectively.

It is important to become familiar with key operations provided by the grids, such as row management, filtering, sorting, and column resizing. These skills aid in development, testing, and debugging.

For instance, row operations allow you to alter, add, or remove rows. This is useful for dynamic or edited datasets. The filtering feature allows users to focus on relevant data. Reordering or formatting columns can improve data presentation. Small modifications enhance the clarity and usability of the grid.

There are many resources available to help you learn. JS grid libraries like AG Grid or Sencha ExtJS offer extensive documentation and examples. These show how filters and sorts operate in real time. By using these tools, you will improve your skills and become a proficient developer.
