README

Laravel blade directives and php helpers for server side rendered content, based on browser window size WITHOUT css. Requires Livewire and AlpineJS

An example to show the purpose of this package:

<?php

if(windowXs() || mobileDevice()) {
 //execute a tiny Eloquent query and return a minimalistic view
}
if(window2xl()) {
 //execute a huge Eloquent query and return a gigantic view
}

Requirements

php 8
Laravel 8
Livewire
AlpineJS

Do you want a pure Javascript version instead?

There is a Laravel/VanillaJS version of this package. Link >>>

Description

The main purpose of this package is not to avoid duplicated html, but to avoid unnecessary server side code execution, just to render content that will never be seen.

AlpineJS syncs the browsers inner width and height, in realtime (debounced 750ms), when the browser window is resized.
The corresponding Livewire component will store the values to the Laravel Session.
The package has a config/breakpoints file where you set your breakpoints
The package provides multiple @blade directives and Laravel helpers()
You have access to the browser window width/height via session('windowW') and session('windowH')
There is also a HasBreakpoints trait to set and get dynamic breakpoints to override config.
You can change the config dynamically with Laravel Config::set(...)

Important note

It's important to understand the difference between the server side rendered breakpoints, that this package provides, and css media queries.

When using css, the content of the page will update in realtime as the user resizes the window, whereas this package debounces a network request.

If you are using a Livewire, the component will update on its next request, otherwise the page will update on the next page request.

It's important that you place the <livewire:breakpoints /> at first point of contact with the user, for your application to look its best. I have it in my app.blade.php and on the login/register pages.

Installation

composer require tanthammar/livewire-window-size

Publish config

php artisan vendor:publish --tag=livewire-window-size

The default settings are based on TailwindCSS breakpoints

'window-width' => [
    // 0 = undefined|false
    // @windowXs (>= 1px && < Sm)
    'Sm' => 640, // => @windowSm (>= 640px && < Md)
    'Md' => 768, // => @windowMd (>= 768px && < Lg)
    'Lg' => 1024, // => @windowLg (>= 1024px && < Xl)
    'Xl' => 1280, // => @windowXl (>= 1280px && < 2xl)
    '2xl' => 1536, // => @window2xl (>= 1536px)
],

Add the component to your layout

Add this to all layouts where you want to keep track of the browser window size.
You will have access to the browser window width/height via session('windowW') and session('windowH')

Example: app.blade.php

<livewire:breakpoints />

Blade directives

@elsif..., @else..., @end..., @unless... and @endif works with all the directives. Explanation in Laravel docs.

//Browser width, with example values
@windowWidthLessThan(400)
@windowWidthGreaterThan(399)
@windowWidthBetween(400, 1500)

//Browser height, with example values
@windowHeightLessThan(500)
@windowHeightGreaterThan(499)
@windowHeightBetween(400, 900)

//Breakpoints based on config values
@windowXs()
@windowSm()
@windowMd()
@windowLg()
@windowXl()
@window2xl()

Example

@windowXs()
<div>This window is extra small</div>
@endif

@window2xl()
<div>This window is very large</div>
@endif

Helpers

Same name as Blade directives

//Mobile device detection based on request header.
mobileDevice()

//Browser width, with example values
windowWidthLessThan(400)
windowWidthGreaterThan(399)
windowWidthBetween(400, 1500)

//Browser height, with example values
windowHeightLessThan(500)
windowHeightGreaterThan(499)
windowHeightBetween(400, 900)

//Breakpoints based on config values
windowXs()
windowSm()
windowMd()
windowLg()
windowXl()
window2xl()

Example php

if(windowXs()) {
 //execute a tiny Eloquent query and return a minimalistic view
}
if(window2xl()) {
 //execute a huge Eloquent query and return a gigantic view
}

HasBreakpoints trait

Add the trait to a component to import config values and get/set custom breakpoints dynamically.

use Tanthammar\LivewireWindowSize\HasBreakpoints;

class Foo extends \Livewire\Component
{
    use HasBreakpoints;
    ...
}

Blade directives test component

Add this to any blade view to test the blade directives

<x-breakpoints::test-windowsize />
