Now.js Framework

Modern JavaScript Framework that Minimizes Code Writing
Write Less JavaScript, Achieve More with the Power of Data Attributes

Overview

Now.js is a JavaScript Framework designed to minimize JavaScript coding by using Data Attributes to control web page behavior and automatically invoke pre-installed features.

Core Philosophy

<!-- Instead of writing JavaScript like this... -->
<script>
  document.querySelector('#myForm').addEventListener('submit', async (e) => {
    e.preventDefault();
    const data = new FormData(e.target);
    await fetch('/api/submit', { method: 'POST', body: data });
  });
</script>

<!-- Just use Data Attributes! -->
<form data-form data-action="/api/submit" data-method="POST">
  <!-- Your form content -->
</form>

No additional JavaScript needed! The framework handles everything automatically.

Real-World Examples

Example 1: CRUD Form

<form data-form
      data-action="/api/products"
      data-method="POST"
      data-on-success="redirect:/products">

  <input type="text"
         name="name"
         data-required
         data-min-length="3"
         placeholder="Product Name">

  <input type="number"
         name="price"
         data-required
         data-min="0"
         placeholder="Price">

  <select name="category" data-required>
    <option value="">Select Category</option>
    <option value="1">Electronics</option>
    <option value="2">Clothing</option>
  </select>

  <textarea name="description"
            data-required
            placeholder="Description"></textarea>

  <button type="submit">Save</button>
</form>

Example 2: Interactive DataTable

<table data-table
       data-source="/api/products"
       data-pagination="true"
       data-page-size="10"
       data-search="true"
       data-row-actions="edit,delete">
  <thead>
    <tr>
      <th data-sort="name" data-field="name">Product Name</th>
      <th data-sort="price" data-field="price">Price</th>
      <th data-field="category">Category</th>
      <th data-field="actions">Actions</th>
    </tr>

</table>

Example 3: Reactive Component

<div data-component="ProductList" data-source="/api/products">
  <!-- Search -->
  <input type="text"
         data-model="search"
         placeholder="Search products">

  <!-- Product List -->
  <div data-for="product in filteredProducts">
    <div class="product-card">
      <h3 data-bind="product.name"></h3>
      <p data-bind="product.price" data-format="currency"></p>
      <button data-on-click="addToCart(product.id)">
        Add to Cart
      </button>
    </div>
  </div>

  <!-- Empty State -->
  <div data-if="filteredProducts.length === 0">
    <p>No products found</p>
  </div>
</div>
