README

JsAsset is a small utility class that discovers JavaScript files, renders them as <script> tags, or returns their content directly (optionally minified).

The class works with:

• local files in assets/*.js
• optional JS files from Composer dependencies (vendor/<vendor>/<package>/*.js)

Purpose

Typical use cases:

• automatically discover available JS assets
• generate script tags for templates from one central place
• serve JS content through your own endpoint (with optional minification)
• use file-based cache and manifest invalidation when source files change

Installation

composer require braesident/js_assets

Available API

• JsAsset::getAssets(): array
• JsAsset::getScriptTagArray(string $path = '', string ...$matches): array
• JsAsset::getScriptTags(string $path = '', string ...$matches): string
• JsAsset::getAsset(string $path, bool $minify = false): string

Snippets

1) Render script tags for all assets

<?php

use braesident\JsAsset\JsAsset;

echo JsAsset::getScriptTags('/asset');

Example output:

<script type="text/javascript" src="/asset/app.js"></script>
<script type="text/javascript" src="/asset/dropdown.js"></script>

2) Render only specific assets

<?php

use braesident\JsAsset\JsAsset;

$tags = JsAsset::getScriptTagArray('/asset', 'app', 'dropdown');

foreach ($tags as $tag) {
  echo $tag.PHP_EOL;
}

3) Return raw asset content (for a controller/route)

<?php

use braesident\JsAsset\JsAsset;

header('Content-Type: application/javascript; charset=UTF-8');
echo JsAsset::getAsset('/asset/dropdown.js');

4) Return minified content with cache

<?php

use braesident\JsAsset\JsAsset;

header('Content-Type: application/javascript; charset=UTF-8');
echo JsAsset::getAsset('/asset/dropdown.js', true);

When true is passed, matthiasmullie/minify is used. Generated files are written to:

• cache/ (non-minified)
• cache/mini/ (minified)
• cache/manifest.json (path, mtime, hash per asset)

If a source file changes, cache entries are refreshed automatically.

Notes About Asset Names

• In getAsset(), only the asset file name is relevant; prefixes like /asset/ and .js are tolerated.
• If local and external assets share the same base name, an external key can appear as <vendor>.<package>.<filename>.
