TYPO3 fe_performance¶
This extension helps to improve frontend performance in TYPO3 CMS. It adds JS minification and some tweaks to the JS handling in general. It's possible to minify all generated HTML.
Features¶
TYPO3 does gzip compression but no minification of JS files. This extension adds JavaScript minification to files and inline scripts by using the jsCompressHandler hook. Usage: config.compressJs needs to be enabled, gzip compression works as before.
When using "config.removeDefaultJS = external" TYPO3 generates temp JavaScript files with all per page inline JS and some default JS. This way users need to download code from statc files multiple times, just because its merged with per page inline JS. You could exclude these files from concatenation with static files (includeJS and includeJSFooter) by enabling excludeInlineJsFromConcatenation in extension manager.
When using includeJSFooter to add JS files it's a little annoying the only remaining JS file in header is the default one. You could use option moveInlineJsToFooter in EM to move the file to the footer section.
JavaScript minifiers¶
Choose the one best fitting for your needs. Configure this in the EM.
JSMin+ Widely used JS compressor. A PHP port of Brendan Eich's Narcissus original implementation. http://crisp.tweakblogs.net/blog/6861/jsmin%2B-version-14.html
