Asset Collector for TYPO3
This extension adds ViewHelpers to dynamically add CSS, JS and SVG files and CSS inline strings to be added to the HTML document from within Fluid Templates. In addition, including JS files are added via a registry to be only added once, which can be achieved via TypoScript as well.
The main benefit over TYPO3 Core functionality is that AssetCollector API is a straightforward approach for integrators to not worry about having duplicate assets entries added again, and to only include the assets that are necessary. This way, integrators can build content types or plugins and attach only necessary resources to one content type, even if it was added multiple times by any editor.
Installation & Requirements
Use composer req b13/assetcollector
or install it via TYPO3's Extension Manager from the
TYPO3 Extension Repository using the extension key assetcollector
.
You need TYPO3 v9 or later to use this extension.
JavaScript includes
This is useful when adding JavaScript files via TypoScript or within a Fluid template based on content element. In contrast to TYPO3 Core, the following functionality is given:
- A JavaScript resource can be added multiple times, but is only added once.
- By having a flexible API, additional attributes such as "async" or "amp" can be added directly.
All JavaScript data is always added within the "head" tag.
If adding via TypoScript, the following syntax applies:
page.jsFiles {
analytics = https://analytics.b13.com/track.js
analytics.async = 1
analytics.data-myattribute = true
}
CSS inliner
This is useful for adding inline-CSS that targets "above the fold" content based on content the editor adds to the page,
or to add CSS inline styles that add background images for specific breakpoints (media queries are possible in the html
head, not in inline styles using the style
attribute for specific elements).
Examples
In your Fluid templates use the ViewHelper to add CSS files or inline CSS code to the head of any page using this template file:
This includes the content of myCssFile.css
inline as a style block in the HTML head of the document.
This adds the string .b_example { color: red; }
to the inline style block in the HTML head of the document.
Remember to add the Fluid namespace to your Fluid templates (or do this globally, see below):
CSS file include
The include option is useful for including CSS files as externally referenced files based on content of your pages. Depending on the size of the CSS and the number of pages the same CSS is used inlining the CSS into the page might not be the best option. To include a CSS file across all pages of your installation could result in including way too much CSS for some of your content pages.
The ViewHelper for including CSS can be used to include CSS files within your Fluid Templates as external files by
adding external="1"
. This adds the CSS file reference to the <head>
part of your <html>
document:
This will add the following code within the <head>
of your document:
You can also specify a value for the media
argument:
SVG Map inliner
Adds SVG files as inline map using a ViewHelper. A file can be added using a file path or an icon name set in your TypoScript setup.
This only includes the icons needed on a given page as inline SVG symbols in one svg map.
Examples
Using a file path
This adds the svg inline code to your template output
and adds the symbol from myIconFile.svg
to the page's inline SVG map. The file name should be unique and is used
to identify the icon within the <use>
-tag. Multiple uses of the same filename will result in the icon being included
only once (correctly so) in the SVG map.
Using a name/identifier set in your TypoScript setup
This will add the svg inline code to your template output using iconName
as an identifier.
Notes on automated rendering of the svg map
The svg file is parsed and all children of the first <svg>
tag are being included in a <symbol>
section within the
svg map. The id of the symbol will be icon-<filename>
and the viewBox
from the original <svg>
tag will be added
as an attribute to the <symbol>
tag.
All <symbol>
sections will be wrapped:
