README

A Laravel package to help users implement media lazy loading using PHP and JavaScript, optimizing page load speeds by only loading media when they are in view. It runs automatically when you load a view or page. Increase your website performance on page load and save bandwidth.

Installation

Media Lazy Load for Laravel requires PHP 7.4 or higher. This particular version supports Laravel 8.x, 9.x, 10.x, 11.x, 12.x, and 13.x.

To get the latest version, simply require the project using Composer:

composer require debjyotikar001/media-lazy-load

Configuration

Media Lazy Load for Laravel supports optional configuration. To get started, you'll need to publish all vendor assets:

php artisan vendor:publish --provider="Debjyotikar001\MediaLazyLoad\MediaLazyLoadServiceProvider"

This will create a config/medialazyload.php file in your app that you can modify to set your configuration. Also, make sure you check for changes to the original config file in this package.

Register the Middleware

In order to add media lazy loading functionality in Laravel, you need to add the MedLazyLoad middleware.

(Laravel 10 or older)

In app/Http/Kernel.php file:

protected $middleware = [
  // other middleware
  \Debjyotikar001\MediaLazyLoad\Middleware\MedLazyLoad::class,
];

or

protected $middleware = [
  // other middleware
  'medialazyload',
];

You can use the middleware class or middleware alias medialazyload in web middleware or route.

(Laravel 11 or newer)

In bootstrap/app.php file:

->withMiddleware(function (Middleware $middleware) {
  $middleware->web(append: [
    // other middleware
    \Debjyotikar001\MediaLazyLoad\Middleware\MedLazyLoad::class,
  ]);
})

or

->withMiddleware(function (Middleware $middleware) {
  $middleware->web(append: [
    // other middleware
    'medialazyload',
  ]);
})

You can use the middleware class or middleware alias medialazyload in web middleware or route.

Usage

This is how you can use MediaLazyLoad for Laravel in your project.

Enable

You must set true on enabled in the config/medialazyload.php file enable media lazy loading functionality. For example:

// config/medialazyload.php
'enabled' => env('MEDLAZYLOAD_ENABLED', true),

# .env
MEDLAZYLOAD_ENABLED=true

HTML Lazy Loading

You can lazy load or defer the rendering of HTML content using the custom Blade directives @lazyHtml and @endLazyHtml. Any content wrapped inside these directives will be placed inside a <template> tag, so it won’t render immediately with the rest of the page. This helps speed up the initial render by keeping non-critical content out of the first paint.

For example:

<!-- This HTML will render normally(or NOT be lazy loaded) -->
<h1>This content is loaded immediately</h1>

<!-- This HTML will be lazy loaded -->
@lazyHtml
  <div>
    <h1>This is lazy HTML content</h1>
  </div>
@endLazyHtml

This will compile to:

<h1>This content is loaded immediately</h1>

<template class="lazy-html" data-lazyhtml="true">
  <div>
    <h1>This is lazy HTML content</h1>
  </div>
</template data-lazyhtml>

Excluding User Agents

Sometimes you may want to disable HTML lazy loading for specific user agents (e.g. search engine crawlers). You can configure this in the package config file config/medialazyload.php:

'excluded_user_agents' => [
  'Googlebot',
  'Bingbot',
  'Slurp',
],

If the current request matches any of these User Agents, the @lazyHtml ... @endLazyHtml directives will render normally (without <template> wrapping).

Allowed Environments

If you want to disable it in specific environments such as during local development or testing to simplify debugging. Then set environments values in a comma (,) separated string in the config/medialazyload.php file, default local,production,staging. For example:

// config/medialazyload.php
'allowed_envs' => env('MEDLAZYLOAD_ALLOWED_ENVS', 'local,production,staging'),

# .env
MEDLAZYLOAD_ALLOWED_ENVS=local,production,staging

Skip or Ignore specific Routes Urls

If you want to skip or ignore specific routes urls, then you have to set paths in the config/medialazyload.php file. You can use '*' as wildcard. For example:

'skip_urls' => [
    '/',
    'about',
    'user/*',
    '*_dashboard',
    '*/download/*',
  ],

Example URLs:

• /: Home URL will be excluded from minification.
• about: This exact URL will be excluded from minification.
• user/*: Any URL starting with user/ (like user/profile, user/settings) will be excluded.
• *_dashboard: Any URL ending with _dashboard (like admin_dashboard, user_dashboard) will be excluded.
• */download/*: Any URL has download (like pdf/download/001, image/download/debjyotikar001) will be excluded.

Exclude Specific Media from Lazy Loading

If you want certain media (image, iframe, video, audio, or elements with background-image) to load normally without lazy loading, you can add the attribute media="no-lazy" to that element. For example:

<!-- This image will NOT be lazy loaded -->
<img src="/logo.png" media="no-lazy">

<!-- This iframe will NOT be lazy loaded -->
<iframe src="https://www.youtube.com/embed/12345" media="no-lazy"></iframe>

<!-- This video will NOT be lazy loaded -->
<video src="/intro.mp4" media="no-lazy" autoplay muted></video>

<!-- This background image will NOT be lazy loaded -->
<div style="background-image:url('/banner.jpg')" media="no-lazy"></div>

Root Margin

This option allows you to control how early or late the elements should be lazy-loaded relative to their position in the viewport. You can set values in the config/medialazyload.php file, default '0px 0px 100px 0px'. Format: 'top right bottom left'. For example:

// config/medialazyload.php
'rootMargin' => env('MEDLAZYLOAD_ROOTMARGIN', '0px 0px 100px 0px'),

# .env
MEDLAZYLOAD_ROOTMARGIN="0px 0px 100px 0px"

Here '0px 0px 100px 0px' means that elements will start loading 100px before they enter the viewport from the bottom. You can also use percentages (e.g., '10% 0px 0px 0px').

Threshold

This option allows you to control how much of an element must be visible in the viewport before it starts loading. It accepts a value between 0 and 1. You can set values in the config/medialazyload.php file, default 0.1. For example:

// config/medialazyload.php
'threshold' => env('MEDLAZYLOAD_THRESHOLD', 0.1),

# .env
MEDLAZYLOAD_THRESHOLD=0.1

Here 0.1 means the element will start loading when 10% of it is visible in the viewport.

Example values:

• 0 means elements will start loading as soon as one pixel is visible.
• 1 means the element will only load when it's fully visible in the viewport.
• 0.05 means that 5% of the element needs to be visible before loading starts.
• 0.1 means that 10% of the element needs to be visible before loading starts.
