Overview

When it comes to creating a seamless user experience, it's essential to handle errors and exceptions in a way that's both informative and non-intrusive. In this article, we'll explore how to implement an error toast on a product add page, ensuring that users are aware of any issues that may arise during the submission process.

Why Error Toasts Matter

Error toasts are a crucial aspect of user interface design, providing users with immediate feedback on any errors or exceptions that occur during their interactions with a website or application. By displaying an error toast, you can:

Inform users of any issues that may have prevented the submission of their data
Provide a clear and concise message about the error, helping users understand what went wrong
Offer a way for users to rectify the issue and continue with their task

Implementing Error Toasts with Toast UI

To implement an error toast on a product add page, we'll use the Toast UI library, a popular and widely-used JavaScript library for creating customizable toasts. Here's a step-by-step guide to getting started:

Step 1: Include Toast UI in Your Project

First, you'll need to include the Toast UI library in your project. You can do this by including the following script tag in your HTML file:

<script src="https://uicdn.toast.com/toast/js/toast.min.js"></script>

Step 2: Create an Error Toast Function

Next, create a function that will be responsible for displaying the error toast. This function will take the error message as an argument and will use the Toast UI library to create and display the toast.

function showErrorToast(errorMessage) {
  Toast.fire({
    icon: 'error',
    title: 'Error',
    text: errorMessage,
  });
}

Step 3: Display the Error Toast

Now that we have the error toast function, we can display it whenever an error occurs on the product add page. For example, if the user submits the form without filling in a required field, we can call the showErrorToast function with the error message.

const form = document.getElementById('product-form');

form.addEventListener('submit', (e) => {
  e.preventDefault();

  const requiredFields = document.querySelectorAll('#product-form input.required');

  if (requiredFields.length > 0) {
    const errorMessage = 'Please fill in all required fields.';
    showErrorToast(errorMessage);
  } else {
    // Form submission logic goes here
  }
});

Customizing the Error Toast

While the default error toast provided by Toast UI is functional, you may want to customize it to fit your application's branding and design. Here are a few ways you can customize the error toast:

Change the icon: You can change the icon displayed on the error toast by modifying the icon property in the showErrorToast function. For example, you can use the warning icon instead of the default error icon.

function showErrorToast(errorMessage) Toast.fire({ icon 'warning', title: 'Warning', text: errorMessage, ); }


*   **Add a close button**: You can add a close button to the error toast by including the `buttons` property in the `showErrorToast` function. For example, you can add a close button that will dismiss the toast when clicked.

    ```javascript
function showErrorToast(errorMessage) {
  Toast.fire({
    icon: 'error',
    title: 'Error',
    text: errorMessage,
    buttons: {
      confirm: {
        text: 'Close',
        className: 'btn btn-secondary',
        closeModal: true,
      },
    },
  });
}

Best Practices for Implementing Error Toasts

When implementing error toasts, keep the following best practices in mind:

Keep it concise: Error toasts should be brief and to the point. Avoid including too much information or unnecessary details.
Use clear language: Use clear and concise language in your error toasts to ensure that users understand what went wrong.
Provide a clear call-to-action: Provide a clear call-to-action in your error toast, such as a link to a help page or a button to dismiss the toast.
Test thoroughly: Test your error toasts thoroughly to ensure that they are working as expected and providing a good user experience.
