Leaf UI [WIP v0.2.0]

Leaf UI is a PHP library for building user interfaces.

Leaf UI doesn't need a new compiler or any extensive compiling, it's just the same old PHP you write everyday; as such, you can build full scalable Leaf UI powered apps or just sprinkle Leaf UI into your existing HTML/PHP code.

v0.2.0 of Leaf UI is currently in development, it is a complete rewrite of the library that comes with a lot of new features and a new API. Leaf UI v0.2.0 will allow you to build full scalable Leaf UI powered apps, write reactive UIs all in PHP. You can think of it as a PHP version of React.

Installing Leaf UI

Like most PHP libraries, we recommend installing Leaf UI with the Leaf CLI:

leaf install ui@dev-next

Or with composer. Just open up your console and type:

composer require leafs/ui:dev-next

After this, you can use all of Leaf UI's methods and components.

Building your first Leaf UI

Since Leaf UI is modelled after React, everything is a component. You can create your own components and handle your application state in them.


use Leaf\UI\Component;

class Test2 extends Component
    // every component needs a unique key
    public $key = "test2";
    public $count = 1;

    public function increment()

    public function decrement()

    public function render()
        // your UI will go here
        return '
                    <div>Static text</div>
                    <button @click="decrement">-</button>
                    <h1>{{ $count }}</h1>
                    <button @click="increment">+</button>

This component renders some static text, a button to decrement a counter, a counter and a button to increment the counter. The counter is stored in the component's state and is updated when the buttons are clicked.

To actually make this work, you simply need to render this component wherever you want it to appear.


use Leaf\UI;

require __DIR__ . '/vendor/autoload.php';

UI::render(new Test2());

The most beautiful part about all this is that it can run outside Leaf. It is completely independent of Leaf or any other framework and can be used in any PHP application.
