Implementing Delete Functionality Without JavaScript

In this tutorial, we'll explore how to implement delete functionality without relying on JavaScript, using server-side processing. This approach ensures the functionality remains intact even when JavaScript is disabled.

1. Setting Up the Server-Side Component

First, let's create the server-side component that handles the delete action. We'll use a server framework like Node.js with Express.

//Function for deleting a task
export const deleteTask = async (formdata) => {
  const id = formdata.get("id");
  await prisma.task.delete({
    where: {
      id,
    },
  });
  revalidatePath("/tasks");
};

2. Creating the Delete Form

Next, let's set up the HTML form for deleting a task. We'll use a standard form submission to trigger the server-side delete action.

<form action="/deleteTask" method="POST">
    <input type="hidden" name="ID" value="taskId">
    <button class="btn btn-error">Delete</button>
</form>

Here, the hidden input field stores the ID of the task to be deleted. When the user clicks the delete button, the form is submitted to the server-side endpoint for processing.

3. Server-Side Processing

Upon receiving the request to delete a task, the server-side component extracts the task ID from the request body and performs the necessary logic to delete the task from the database.

This ensures that the delete functionality remains accessible and functional even when JavaScript is disabled.

4. Testing Without JavaScript

To demonstrate the robustness of this approach, let's disable JavaScript in the browser and test the delete functionality.

Even with JavaScript disabled, users can still delete tasks using the form submission method. The server-side component handles the delete action seamlessly.

Conclusion

By implementing delete functionality without relying on JavaScript, we ensure a more inclusive user experience. Users with JavaScript disabled can still perform essential actions, demonstrating the resilience of our application.
