jQuery Frontend Website Development
jQuery — library with 18-year history, still used on 77% of top 10 million websites by W3Techs data. Not because developers don't know about React — but because jQuery solves specific tasks without build pipeline, without node_modules, and without team of five people.
We develop frontend on jQuery for projects where this is technically justified: CMS without npm environment, legacy system integration, WordPress themes, administrative panels on Bootstrap.
When jQuery is the right choice
- Project uses WordPress, Joomla, OpenCart or another CMS with jQuery in core
- Backend on PHP without Node.js in infrastructure
- Support team has no experience with modern frameworks
- Minimal overhead required — one
<script>tag and it works - Integration with jQuery plugins: Select2, DataTables, FullCalendar, Fancybox
What's included in development
Basic interactive site:
- AJAX requests via
$.ajax/$.get/$.postwith error handling - Dynamic forms with validation via
jquery-validation - List filtering and sorting
- Modal windows, dropdowns, accordions
- jQuery plugin initialization and setup
Example typical code:
$(function () {
// Event delegation for dynamically added elements
$(document).on('click', '.js-delete-item', function () {
const $btn = $(this);
const id = $btn.data('id');
if (!confirm('Delete record?')) return;
$.ajax({
url: `/api/items/${id}`,
method: 'DELETE',
headers: { 'X-CSRF-TOKEN': $('meta[name="csrf-token"]').attr('content') },
beforeSend: () => $btn.prop('disabled', true),
success: () => $btn.closest('tr').fadeOut(300, function () { $(this).remove(); }),
error: (xhr) => {
alert(xhr.responseJSON?.message || 'Error');
$btn.prop('disabled', false);
}
});
});
});
Code organization
For medium-sized projects modular structure without bundler:
assets/
js/
modules/
cart.js // $.fn.cart = function() {...}
search.js
forms.js
vendor/
jquery.min.js
select2.min.js
app.js // module initialization
Each module formatted as jQuery plugin or IIFE function. This gives isolation without webpack.
Timeline
- Week 1: JS structure, plugin connection, basic UI components
- Week 2: forms, AJAX, server API integration
- Week 3: testing, cross-browser compatibility, optimization
For jQuery projects we also set up minification via gulp or simple concat script, so you don't need to drag Node.js to production environment unnecessarily.
