Usage

Example of use for this library:

Add body script

use Josantonius\Asset\Elements\BodyScript;

new BodyScript(
    src: 'https://example.com/script.js'
);

use Josantonius\Asset\Facades\Asset;

Asset::addBodyScript(
    src: 'script.js',
    type: 'text/javascript'
);

Add head script

use Josantonius\Asset\Elements\HeadScript;

new HeadScript(
    src: 'script.js',
    type: 'module'
);

use Josantonius\Asset\Facades\Asset;

Asset::addHeadScript(
    crossorigin: 'anonymous',
    defer: true,
    integrity: 'sha256-n9+',
    src: 'https://example.com/script.js',
    type: 'text/javascript'
);

Add link

use Josantonius\Asset\Elements\Link;

new Link(
    crossorigin: 'anonymous',
    href: 'https://example.com/style.css',
    integrity: 'sha256-n9+',
    media: 'all',
    rel: 'stylesheet'
);

use Josantonius\Asset\Facades\Asset;

Asset::addLink(
    href: 'https://example.com/style.css',
    rel: 'stylesheet'
);

Print the added scripts for the body

use Josantonius\Asset\Asset;

$asset = new Asset();

echo $asset->outputBodyScripts();

use Josantonius\Asset\Facades\Asset;

echo Asset::outputBodyScripts();

Print the added scripts for the head

use Josantonius\Asset\Asset;

$asset = new Asset();

echo $asset->outputHeadScripts();

use Josantonius\Asset\Facades\Asset;

echo Asset::outputHeadScripts();

Print the added links

use Josantonius\Asset\Asset;

$asset = new Asset();

echo $asset->outputLinks();

use Josantonius\Asset\Facades\Asset;

echo Asset::outputLinks();

Full example

index.php

use Josantonius\Asset\Elements\Link;
use Josantonius\Asset\Elements\BodyScript;
use Josantonius\Asset\Elements\HeadScript;

new BodyScript(src: 'foo.js', async: true);
new BodyScript(src: 'bar.js', type: 'text/javascript');

new HeadScript(src: 'https://example.com/foo.js', type: 'module');
new HeadScript(src: 'https://example.com/bar.js', defer: true);

new Link(href: 'https://example.com/foo.css', rel: 'stylesheet');
new Link(href: 'https://example.com/bar.css', rel: 'stylesheet', media: 'all');

page.html

<?php
use Josantonius\Asset\Asset;
$asset = new Asset();
?>
<html>
  <head>
    <?= $asset->outputLinks() ?>
    <?= $asset->outputHeadScripts() ?>
  </head>
  <body>
    <?= $asset->outputBodyScripts() ?>
  </body>
</html>

Result:

<html>
  <head>
    <link href="https://example.com/foo.css" rel="stylesheet">
    <link href="https://example.com/bar.css" rel="stylesheet" media="all">
    <script src="https://example.com/foo.js" type="module"></script>
    <script defer src="https://example.com/bar.js"></script>
  </head>
  <body>
    <script async src="foo.js"></script>
    <script src="bar.js" type="text/javascript"></script>
  </body>
</html>

Full example using the facade

index.php

use Josantonius\Asset\Facades\Asset;

Asset::addBodyScript(src: 'foo.js', async: true);
Asset::addBodyScript(src: 'bar.js', type: 'text/javascript');

Asset::addHeadScript(src: 'https://example.com/foo.js', type: 'module');
Asset::addHeadScript(src: 'https://example.com/bar.js', defer: true);

Asset::addLink(href: 'https://example.com/foo.css', rel: 'stylesheet');
Asset::addLink(href: 'https://example.com/bar.css', rel: 'stylesheet', media: 'all');

page.html

<?php
use Josantonius\Asset\Facades\Asset;
?>
<html>
  <head>
    <?= Asset::outputLinks() ?>
    <?= Asset::outputHeadScripts() ?>
  </head>
  <body>
    <?= Asset::outputBodyScripts() ?>
  </body>
</html>

Result:

<html>
  <head>
    <link href="https://example.com/foo.css" rel="stylesheet">
    <link href="https://example.com/bar.css" rel="stylesheet" media="all">
    <script src="https://example.com/foo.js" type="module"></script>
    <script defer src="https://example.com/bar.js"></script>
  </head>
  <body>
    <script async src="foo.js"></script>
