README

Integrate the Assetic asset management framework into your TYPO3 CMS installation.

Installation

1. composer require cundd/assetic
2. Load the Site Set into the TYPO3 Site
3. Configure the assets you want to be loaded
4. Include the plugin the page.headerData

   // Example:
   page.headerData.40001 =< plugin.tx_assetic
   

Usage

Basic

# File: config/sites/my-site/settings.yaml or EXT:site_package/Configuration/Sets/Site/settings.yaml
assetic:
    stylesheets:
        - file: EXT:site_package/Resources/Private/Stylesheets/main.css

Multiple assets

# File: config/sites/my-site/settings.yaml or EXT:site_package/Configuration/Sets/Site/settings.yaml
assetic:
    stylesheets:
        - file: EXT:site_package/Resources/Private/Stylesheets/reset.css
        - file: EXT:site_package/Resources/Private/Stylesheets/style.css

With SASS

If your web server and web user are configured to be able to use the sass command line tool, from within your TYPO3 installation, you could use the following:

# File: config/sites/my-site/settings.yaml or EXT:site_package/Configuration/Sets/Site/settings.yaml
assetic:
    stylesheets:
        - file: EXT:site_package/Resources/Private/Stylesheets/main.scss

With other CSS preprocessors

Analog you can use other CSS preprocessors. The Assetic Github Page provides a (incomplete) list of all filters provided by the installed Assetic version.

Development mode

To make sure that the assets are compiled each time the frontend page is refreshed, you can enable the development mode:

plugin.tx_assetic {
	development = 1
}

By default Cundd Assetic is configured not to compile files if NO backend user is logged in. To allow file compilation without a logged in backend user you can change the allowCompileWithoutLogin configuration in Site Settings.

Advanced

Configure a filter

Some filters allow further customization. The Sass filter e.g. provides the method addImportPath which allows you to add another path to look for imported Sass files. Cundd Assetic provides an interface to invoke such functions.

# File: config/sites/my-site/settings.yaml or EXT:site_package/Configuration/Sets/Site/settings.yaml
assetic:
    stylesheets:
        - file: EXT:site_package/Resources/Private/Stylesheets/main.scss
          functions:
              # Add functions that will be called on the filter
              addImportPath: ProjectPath:/vendor/

If you want to invoke a method multiple times you can just add a numeric prefix to the function name:

# File: config/sites/my-site/settings.yaml or EXT:site_package/Configuration/Sets/Site/settings.yaml
assetic:
    stylesheets:
        - file: EXT:site_package/Resources/Private/Stylesheets/main.scss
          functions:
              # Add a numeric prefix to allow the function to called multiple times
              0-addImportPath: ProjectPath:/vendor/
              1-addImportPath: EXT:site_package/Resources/Private/Library/

Configure the filter binary paths

In some cases you may have to specify the path to a CSS preprocessor to match your system's configuration. This can be done through the filterBinaries configuration.

The configuration keys are determined by replacing \ with _ and converting the string to lowercase:

1. \AsseticAdditions\Filter\DartSassFilter
2. AsseticAdditions_Filter_DartSassFilter
3. asseticadditions_filter_dartsassfilter

# File: config/sites/my-site/settings.yaml or EXT:site_package/Configuration/Sets/Site/settings.yaml
assetic:
    settings:
        filterBinaries:
        	# Change the path to the filter binaries. I.e. if node.js is installed
        	# into /usr/local/bin/
            assetic_filter_lessfilter: /usr/local/bin/node

    		# The binary for filter class \AsseticAdditions\Filter\DartSassFilter
    		asseticadditions_filter_dartsassfilter: /usr/local/bin/sass

Command line

Assetic provides three different CLI commands.

assetic:compile

Compiles the assets and exit.

vendor/bin/typo3 assetic:compile

assetic:watch

Watches for file changes in EXT:client and re-compiles the assets if needed.

vendor/bin/typo3 assetic:watch

assetic:livereload

Starts a LiveReload compatible server that watches for file changes in EXT:client and re-compiles the assets if needed. The necessary JavaScript can be loaded be enabling addJavascript in Site Settings.

vendor/bin/typo3 assetic:livereload

CSP & LiveReload

To use LiveReload with CSP enabled add wss://your-domain.tld:35729/livereload to connect-src in the site's CSP configuration file (config/sites/your-site/csp.yaml).

See the TYPO3 documentation for further details.

Example

mutations:
    - mode: "extend"
      directive: "connect-src"
      sources:
          - "wss://your-domain.tld:35729/livereload"

Additional tools

Standalone auto-refresh tool

Cundd Assetic provides a JavaScript tool that checks the CSS and JavaScript assets on the page for changes and automatically reloads them. For more information and usage visit /Resources/Public/JavaScript.
