How to create a Datepicker with inline editing using AlpineJS with Tailwind CSS?

In this section, we will discuss how to create a Datepicker with inline editing using AlpineJS with Tailwind CSS. We will create a simple UI component that allows users to select and edit dates inline.

Step 1: Set up the project

To set up the project, we need to create a new HTML file and include the required CSS and JavaScript files. We will use Tailwind CSS and AlpineJS CDN links to include the required files.

<!DOCTYPE html>
<html lang="en">
  <head>
    <meta charset="UTF-8" />
    <meta name="viewport" content="width=device-width, initial-scale=1.0" />
    <title>Datepicker with Inline Editing using AlpineJS with Tailwind CSS</title>
    <link
      rel="stylesheet"
      href="https://cdn.jsdelivr.net/npm/tailwindcss@2.0.2/dist/tailwind.min.css"
    />
    <script src="https://cdn.jsdelivr.net/npm/alpinejs@2.7.3/dist/alpine.js"></script>
  </head>
  <body>
    <div class="container mx-auto my-4">
      <!-- Datepicker with inline editing UI component -->
    </div>
  </body>
</html>

Step 2: Create the UI component

To create the Datepicker with inline editing UI component, we need to define a div element with the x-data directive. The x-data directive is used to define the data that will be used in the UI component.

<div
  class="bg-white rounded-lg shadow-lg p-4"
  x-data="{ date: '2021-01-01', isEditing: false }"
>
  <!-- Datepicker with inline editing UI component -->
</div>

In the above code, we have defined a div element with the x-data directive. We have defined two data properties - date and isEditing. The date property is used to store the selected date, and the isEditing property is used to toggle the editing mode.

Step 3: Add the Datepicker UI component

To add the Datepicker UI component, we need to define an input element with the x-model and x-on directives. The x-model directive is used to bind the input value to the date property, and the x-on directive is used to toggle the editing mode.

<div
  class="bg-white rounded-lg shadow-lg p-4"
  x-data="{ date: '2021-01-01', isEditing: false }"
>
  <template x-if="!isEditing">
    <div class="flex items-center">
      <span class="text-gray-600 mr-2">{{ date }}</span>
      <button
        class="text-blue-500 hover:text-blue-700"
        x-on:click="isEditing = true"
      >
        Edit
      </button>
    </div>
  </template>
  <template x-if="isEditing">
    <div class="flex items-center">
      <input
        type="date"
        class="border rounded-lg p-2 mr-2"
        x-model="date"
      />
      <button
        class="text-blue-500 hover:text-blue-700"
        x-on:click="isEditing = false"
      >
        Save
      </button>
    </div>
  </template>
</div>

In the above code, we have defined two templates - one for the non-editing mode and one for the editing mode. In the non-editing mode, we have displayed the selected date and a button to toggle the editing mode. In the editing mode, we have displayed an input element to select the date and a button to save the changes.

Step 4: Style the UI component

To style the UI component, we can use the pre-defined Tailwind CSS classes. We can add the required CSS classes to the HTML elements to style them.

<div
  class="bg-white rounded-lg shadow-lg p-4"
  x-data="{ date: '2021-01-01', isEditing: false }"
>
  <template x-if="!isEditing">
    <div class="flex items-center">
      <span class="text-gray-600 mr-2">{{ date }}</span>
      <button
        class="text-blue-500 hover:text-blue-700"
        x-on:click="isEditing = true"
      >
        Edit
      </button>
    </div>
  </template>
  <template x-if="isEditing">
    <div class="flex items-center">
      <input
        type="date"
        class="border rounded-lg p-2 mr-2"
        x-model="date"
      />
      <button
        class="bg-blue-500 text-white rounded-lg px-4 py-2 hover:bg-blue-700"
        x-on:click="isEditing = false"
      >
        Save
      </button>
    </div>
  </template>
</div>

In the above code, we have added the required Tailwind CSS classes to the HTML elements to style them. We have used the bg-white, rounded-lg, shadow-lg, p-4, text-gray-600, text-blue-500, hover:text-blue-700, border, mr-2, bg-blue-500, text-white, px-4, py-2, and hover:bg-blue-700 classes to style the UI component.

Conclusion

In this article, we have discussed how to create a Datepicker with inline editing using AlpineJS with Tailwind CSS. We have used the x-data, x-model, x-on, and x-if directives to create the UI component. We have also used the pre-defined Tailwind CSS classes to style the UI component. This UI component is useful for applications that require users to select and edit dates frequently.
