Advanced CSS/JS Aggregation
7.x & 8.x
Summary (7.x & 8.x)
AdvAgg allows you to improve the frontend performance of your site. Be sure to do a before and after comparison by using Google's PageSpeed Insights and WebPagetest.org. The performance benefits are achieved by using some of the features found in AdvAgg and its sub modules. Out of the box AdvAgg's frontend performance will be similar to cores.
Features & benefits (7.x & 8.x)
- Stability - If the Aggregate doesn't exist it will be generated on demand.
- Stability - Stampede file protection. Uses locking so multiple requests for the same thing will result in only one thread doing the work.
- Backend - Render Cache; cache the generated HTML.
- Backend - Zero file I/O if the Aggregated file already exists. Big improvement if using a networked filesystems (NFS, S3, etc).
- Frontend - Combine CSS files by using media queries; better CSS groupings.
- Frontend - DNS Prefetch. Start DNS lookup for external domains as soon as possible.
- Frontend - Workaround IE 6-9 CSS limitation by preventing more than 4095 selectors in a CSS file.
- Frontend - Brotli/Gzip support. Compress files into a .gz/.br file and serve from Apache. This is faster then compressing the file on each request.
- DX - Browser conditional comments for CSS and JS.
- DX - All attributes are supported.
- DX - D8 Features backported when feasible.
- DX - Add JS to any region of the theme; also to any view or block.
- DX - Admin can drop a cookie that will turn off file aggregation (theme development).
- DX - Url query string to turn off aggregation for that request.
?advagg=0will turn off file aggregation if the user has the "bypass advanced aggregation" permission.
?advagg=-1will completely bypass all of Advanced CSS/JS Aggregations modules and submodules.
Submodules (7.x & 8.x)
- Frontend - Async Font Loader. Text is readable before the webfont has been downloaded; usable site quicker.
- Frontend - Bundler Submodule. Given a target number of CSS/JS aggregates, this will try very hard to meet that goal. It smartly groups files together.
- Frontend - CSS/JS Compress Submodules. Can minifiy files & inline CSS/JS. Can also turn off core CSS compression for theme development.
- Frontend - Relocate Submodule. Will move external CSS and JS files to be local. Allows for long browser caches, and faster page rendering.
- Security - Subresource Integrity. Provides a hash of the CSS/JS file allowing for assets delivered over a CDN to be verified.
- DX - CSS/JS Validator Submodule. Validate all CSS files using jigsaw.w3.org. Check all CSS files with CSSLint. Check all JS files with JSHint
HTTP Parallel Request & Threading Library is not required but is recommended so Aggregates will be built in the background.
