How to create a Textarea Live Letters Counter with AlpineJS with Tailwind CSS?

To create a Textarea Live Letters Counter with AlpineJS with Tailwind CSS, follow these steps:

Step 1: Create the HTML markup

First, create the HTML markup for the Textarea Live Letters Counter. The HTML markup should include a textarea element and a span element to display the character count.

<div class="w-full">
  <textarea
    x-data="{ count: 0 }"
    x-init="count = $refs.textarea.value.length"
    x-on:input="count = $refs.textarea.value.length"
    class="w-full px-3 py-2 leading-tight border rounded shadow appearance-none focus:outline-none focus:shadow-outline"
    rows="5"
    placeholder="Enter text here..."
    x-ref="textarea"
  ></textarea>
  <div class="text-right text-xs text-gray-500 mt-1">
    <span x-text="count"></span> / 100
  </div>
</div>

In the above code, we have used the x-data directive to create a reactive data property called count. We have also used the x-init directive to set the initial value of count to the length of the textarea value. The x-on:input directive is used to update the count property whenever the user types in the textarea.

Step 2: Add Tailwind CSS classes

Next, we will add Tailwind CSS classes to style the Textarea Live Letters Counter. We will add classes for the textarea, the span element, and the character count.

<div class="w-full">
  <textarea
    x-data="{ count: 0 }"
    x-init="count = $refs.textarea.value.length"
    x-on:input="count = $refs.textarea.value.length"
    class="w-full px-3 py-2 leading-tight border rounded shadow appearance-none focus:outline-none focus:shadow-outline"
    rows="5"
    placeholder="Enter text here..."
    x-ref="textarea"
  ></textarea>
  <div class="text-right text-xs text-gray-500 mt-1">
    <span x-text="count" class="font-bold"></span> / 100
  </div>
</div>

In the above code, we have added the font-bold class to the span element to make the character count more prominent. We have also added classes for the textarea to make it look like a standard form element.

Step 3: Add AlpineJS directives

Finally, we will add AlpineJS directives to make the Textarea Live Letters Counter interactive. We will add directives to update the character count whenever the user types in the textarea.

<div class="w-full">
  <textarea
    x-data="{ count: 0 }"
    x-init="count = $refs.textarea.value.length"
    x-on:input="count = $refs.textarea.value.length"
    class="w-full px-3 py-2 leading-tight border rounded shadow appearance-none focus:outline-none focus:shadow-outline"
    rows="5"
    placeholder="Enter text here..."
    x-ref="textarea"
  ></textarea>
  <div class="text-right text-xs text-gray-500 mt-1">
    <span x-text="count" class="font-bold"></span> / 100
  </div>
</div>

In the above code, we have used the x-data directive to create a reactive data property called count. We have also used the x-init directive to set the initial value of count to the length of the textarea value. The x-on:input directive is used to update the count property whenever the user types in the textarea.
