PHP wrapper for sass-embedded (Dart Sass via Node.js).

Allows compiling SCSS/SASS to CSS through PHP using Node.js and npm.

Requirements

• PHP >= 8.2
• Node.js >= 18

Installation via Composer

composer require bugo/sass-embedded-php

Usage examples

Compiling SCSS file

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

use Bugo\Sass\Compiler;

$compiler = new Compiler();

$css = $compiler->compileFile(__DIR__ . '/assets/app.scss');

file_put_contents(__DIR__ . '/assets/app.css', $css);

echo "CSS compiled!\n";

Compiling SCSS from string

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

use Bugo\Sass\Compiler;

$compiler = new Compiler();

$scss = '$color: red; body { color: $color; }';
$css = $compiler->compileString($scss);

echo $css;

Compiling string with options

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

use Bugo\Sass\Compiler;

$compiler = new Compiler();

$scss = <<<'SCSS'
$color: #3498db;
$font-size: 14px;

body {
  font-size: $font-size;
  color: $color;
}
SCSS;

$css = $compiler->compileString($scss, [
    'compressed' => true,
    'sourceMap' => true,
]);

echo $css;

Catching compilation errors

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

use Bugo\Sass\Exception;
use Bugo\Sass\Compiler;

$compiler = new Compiler();

$scss = <<<'SCSS'
$color: #e74c3c;
.foo { color: $color; }
SCSS;

try {
    echo $compiler->compileString($scss);
} catch (Exception $e) {
    echo "Compilation error: " . $e->getMessage();
}

Compiling SCSS file with change checking

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

use Bugo\Sass\Exception;
use Bugo\Sass\Compiler;

$compiler = new Compiler();

try {
    $done = $compiler->compileFileAndSave(
        __DIR__ . '/assets/style.scss',
        __DIR__ . '/assets/style.css',
    );

    if ($done) {
        echo "CSS recompiled and saved.\n";
    } else {
        echo "No changes detected, skipped compilation.\n";
    }
} catch (Exception $e) {
    echo "Compilation error: " . $e->getMessage();
}

This method automatically checks if the source file has been modified since the last compilation and only compiles and saves if changes are detected.

Compiling file with source maps and compressed output

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

use Bugo\Sass\Compiler;

$compiler = new Compiler();

$css = $compiler->compileFile(__DIR__ . '/assets/app.scss', [
    'sourceMap' => true,
    'includeSources' => true,
    'sourceMapPath' => __DIR__ . '/assets/',
    'style' => 'compressed',
]);

file_put_contents(__DIR__ . '/assets/app.css', $css);

echo "CSS compiled with source map!\n";

Options

Paths to bridge.js and Node are specified only through the constructor:

$compiler = new Compiler('/path/to/bridge.js', '/path/to/node');

Options can be set either for the entire compiler at once or for a specific method separately:

$compiler->setOptions([
    'syntax' => 'indented',
    'minimize' => true,
    'sourceMap' => true,
]);

Advanced options

These options allow controlling additional aspects of Sass compilation.

$compiler->setOptions([
    'loadPaths' => ['/path/to/custom/libs'],
    'quietDeps' => true,
    'silenceDeprecations' => true,
    'verbose' => true,
]);
