Symfony UX has transformed the way Symfony developers build web interfaces, making it possible to create modern, reactive, and high-performance applications without leaving PHP. This training teaches you to design rich, dynamic user experiences using TwigComponents, LiveComponents, Stimulus, and Turbo, all from within the Symfony ecosystem you already know. The program combines instructor-led sessions with one month of access to the online review platform for continued practice.
Level: Beginner
Duration: 3 days
Available languages: English, German, French
Prerequisites:
A working knowledge of Symfony is required, including routing, controllers, and Twig templating.
Basic familiarity with HTML, CSS, and JavaScript is expected.
Learning Objectives:
Build reusable, testable UI components with TwigComponents
Create reactive interfaces without writing JavaScript using LiveComponents
Add progressive interactivity to existing pages with Stimulus and StimulusBundle
Implement single-page application navigation and partial page updates with Turbo
Test Twig and Live components with PHPUnit and end-to-end tools
Assessment methods
Knowledge is evaluated throughout and at the end of the training via multiple-choice questions. A certificate of completion is issued upon success, along with attendance documentation. Participants receive one month of free access to the online review platform for continued practice.
Day 1 - JavaScript Foundations & TwigComponents
Morning — Modern JavaScript
JavaScript in 2025: understanding the landscape of compiled vs native-code frameworks and where Symfony UX fits
ES6+ syntax essentials: arrow functions, destructuring, spread operator, optional chaining, and async/await
ES6 classes and inheritance: bridging familiar OOP concepts with frontend JavaScript
Import/export module system: organising client-side code with native modules
Morning — TwigComponents
- Component anatomy: defining a component class and its associated Twig template
- Named and anonymous components: choosing the right approach for each use case
- Component lifecycle: understanding how components are instantiated and rendered
- Passing data with props: exposing typed attributes from PHP to the template
Afternoon - LiveComponents
TwigComponents vs LiveComponents: when reactivity justifies the extra layer
Live component anatomy: the #[AsLiveComponent] attribute and its contract with the browser
Data binding: linking HTML inputs directly to component properties
Component lifecycle and re-rendering: how state changes trigger efficient updates
Migrating an existing Twig component to a Live component
Building a Live component from scratch: a practical walkthrough
Day 2 - Stimulus & Advanced LiveComponents
Morning - Stimulus & StimulusBundle
Stimulus philosophy: progressive enhancement, minimal JavaScript, and separation of concerns
Stimulus fundamentals: controllers, targets, actions, values, and CSS classes
StimulusBundle: integrating Stimulus into Symfony and exposing components via Twig functions
Building and connecting a Stimulus controller to an existing page
Afternoon - LiveComponents In Depth
Filtering and sorting with Live components: keeping UI state in sync with server-side logic
Advanced form handling: multi-field live validation and dependent field updates
Multi-step forms: managing wizard-style flows with server-side state
Component communication: emitting events from child components and listening in parent components
Day 3 - Turbo & Testing
Morning - Turbo
Turbo Drive: replacing full page loads with seamless AJAX navigation while keeping the URL bar
Turbo Frames: updating discrete page sections independently without a full reload
Turbo Streams: pushing real-time DOM updates from the server after form submissions or broadcasts
Turbo and Live components: combining both tools for fluid, reactive interfaces
Afternoon — Testing & Ecosystem
Testing TwigComponents with PHPUnit: asserting rendered output and component behaviour
Testing LiveComponents: using the InteractsWithLiveComponents trait for action and binding tests
End-to-end testing with Symfony Panther: driving a real headless browser from your test suite
Fluent browser testing with Zenstruck Browser: chainable assertions over HTTP and browser clients
Symfony UX ecosystem: Maps, Icons, Autocomplete, Chart.js, Notify, Toggle Password, and community packages

See details : Mathieu SantostefanoWhy SensioLabs?
I’ve always been a pure backend guy because the modern JS ecosystem felt like a moving target. This Symfony UX course was a revelation. We learned how to build highly interactive interfaces using Stimulus and Turbo, but staying almost entirely within Twig and PHP. It felt like regaining a superpower. I finally stopped struggling with complex React setups for simple UI updates. If you want to build modern apps without losing the Symfony workflow, this training course is the way.
Thibault Chardian
Senior PHP Developer- A Media Company
We were considering moving to a decoupled Headless architecture just to get the reactivity our clients wanted, but the overhead was daunting. The SensioLabs trainers showed us how Symfony UX (especially Live Components) bridges that gap. The training was incredibly hands-on; we went from basic templates to a fully reactive dashboard in two days. It’s completely changed our project estimates—we can now deliver SPA-like experiences in half the time it used to take us.
