Theme Bundle
============

[](#theme-bundle)

A Symfony bundle that combines and serves CSS/JS files as single bundled assets with intelligent HTTP caching and source map support.

Features
--------

[](#features)

- **File combining** — merge multiple CSS or JS files into a single response
- **Namespace paths** — organize assets with `@namespace/file.css` references
- **HTTP caching** — automatic ETag, Last-Modified, and 304 Not Modified responses
- **Source maps** — v3 source map generation for combined files (configurable)
- **Twig integration** — `themeAsset()` function for easy template usage
- **Performance profiling** — optional Stopwatch integration

Requirements
------------

[](#requirements)

- PHP 8.4+
- Symfony 8.0+
- Twig 3.0+ or 4.0+

Installation
------------

[](#installation)

```
composer require psychob/theme-bundle
```

The bundle auto-registers via Symfony Flex.

Configuration
-------------

[](#configuration)

Create or edit `config/packages/theme.yaml`:

```
theme:
    # Enable source map generation (useful in dev)
    sourcemaps: '%kernel.debug%'

    # Map namespace aliases to filesystem directories
    paths:
        '%kernel.project_dir%/assets/css': app
        '%kernel.project_dir%/vendor/some-lib/styles': lib

    # Define combined file bundles
    files:
        app.css:
            - '@app/reset.css'
            - '@app/layout.css'
            - '@lib/components.css'
            - '@app/main.css'
        app.js:
            - '@app/utils.js'
            - '@app/main.js'
```

[](#usage)

### Twig

[](#twig)

Use `themeAsset()` to generate URLs to combined files:

```

```

This generates URLs like `/_/theme/app.css` and `/_/theme/app.js`.

### HTTP Caching

[](#http-caching)

The bundle serves combined files at `/_/theme/{file}` with:

- **ETag** header for cache validation
- **Last-Modified** header as fallback
- **304 Not Modified** responses when content hasn't changed
- **Cache-Control: public, must-revalidate**

Source maps are served at `/_/theme/{hash}.{ext}.map` with immutable, long-lived cache headers (1 year).

### Namespaces

[](#namespaces)

The `@namespace/` prefix in file paths resolves to the directory mapped in `paths`:

```
theme:
    paths:
        '%kernel.project_dir%/assets/css': app

    files:
        app.css:
            - '@app/reset.css'   # resolves to %kernel.project_dir%/assets/css/reset.css
```

Development
-----------

[](#development)

```
# Run tests
composer test

# Run tests with coverage
composer test:coverage

# Static analysis

# Check code style
