Resolving Ngx-toastr Focus Issues in Angular: A Step-by-Step Guide

When building applications with Angular, the Ngx-toastr library is widely favored for its user-friendly toast notifications. However, sometimes developers encounter issues that can hinder the user experience. One such common problem is when the toast notifications become unfocused and non-interactive, preventing users from taking actions like closing or interacting with the notifications. In this guide, we'll explore a recent issue where developers were unable to regain focus on Ngx-toastr notifications due to changes made in the theme's CSS. Let's dive in!

Understanding the Problem

It's essential to first articulate the issue clearly. As described in a recent inquiry, after purchasing a theme for Angular, users noticed that the default view of the Ngx-toastr had been modified. This change resulted in the toast notifications being rendered non-focusable, meaning that users couldn’t click or interact with the notifications as intended. This could be a significant usability flaw, especially if users needed to perform actions such as closing notifications or activating links within them.

Here’s a snippet of the code that was being used for initializing the Ngx-toastr:

While everything else seemed to work correctly, the inability to focus on the toast notifications was problematic.

The Solution: Modifying CSS

After investigating the problem, the solution was found to lie in a CSS modification. Specifically, it was determined that the toast notifications had a CSS property affecting pointer events. Below is a breakdown of what was discovered:

Issue Identified: The .toastr class was assigned the property pointer-events: none; by custom CSS files associated with the theme. This property effectively disables all mouse interactions with the element, including focus and clicks.

Default Behavior: By default, this property should be set to auto, allowing the textual notifications to be interactive and focusable.

Steps to Solve the Issue

To restore the focus functionality to your Ngx-toastr notifications, follow these steps:

Locate the Custom CSS: Start by finding the CSS file where the .toastr class has been customized. It’s likely included in the theme you purchased.

Modify the Pointer Events:

This alteration will ensure that users can now interact with the toast notifications as intended.

Test Your Changes: Save the changes and refresh your application to see if the Ngx-toastr notifications are now focusable. Users should be able to click on and interact with the toast as needed.

Conclusion

The ability to focus and interact with toast notifications is crucial for a smooth user experience in any application. By understanding how CSS properties can affect functionality, you can quickly troubleshoot and resolve similar issues in the future.
