How to Create a Dynamic Badge for Chat Messages in React CoreUI

If you're working with React and CoreUI, you might run into issues when trying to implement dynamic features, such as a notification badge for new messages in a sidebar chat application. In this guide, we'll take a closer look at how to resolve this problem efficiently. Specifically, we'll cover how to display a "NEW MESSAGE" badge next to the Chat item in your sidebar when there is a new message.

Understanding the Problem

The task is to ensure that the chat badge updates dynamically to show when there’s a new message. The previous code structure uses an array of navigation items for the sidebar, but it doesn’t currently have a mechanism to display or update the badge based on new messages.

Provided Code Overview

Here’s a simplified version of the initial code for context:

In the code, chatBadge is a boolean state that should dictate whether the badge appears, but it isn’t used correctly in the rendering process.

Solution Breakdown

To effectively implement the dynamic badge, we need to conditionally render the badge based on the value of chatBadge. Let's break down the solution into several sections.

Adjust the Sidebar Rendering

The core idea is to conditionally render the badge in the sidebar item corresponding to "Chat". We will modify the code within the JSX where the sidebar items are being rendered.

Updated JSX Code

Here’s how you can implement the dynamic badge:

Explanation of Key Changes

Conditional Badge Rendering: The badge property of CSidebarNavItem is conditionally assigned:

If the item name is "Chat" and chatBadge is true, it will create a badge.

If not, it assigns null, meaning no badge will be displayed.

Mapping Through Filtered Navigation: We use the filteredNav array to generate sidebar items, making sure each item in the sidebar corresponds accurately with its navigation properties.

Conclusion

With these modifications, your sidebar should now correctly display a dynamic badge indicating a new message in your chat application.

Implementing new features like this can initially seem challenging, especially when you're working within existing codebases. However, breaking down the problem into manageable parts, as we've done here, can lead to clear solutions.

Feel free to implement this logic into your own project, and watch as your application becomes more interactive and user-friendly!
