VB4 SuperCharged - Optimises CSS, Javascript And HTML |
Minifies all CSS files and serves CSS directly, eliminating the PHP overhead from css.php. Intelligently defers javascript loading and combines common javascript files. Also features optional compression with Google Closure Compiler. Based on HELLCAT's Realtime Page Compressor, and adds complete whitespace removal around block and meta elements and removal of unimportant comments. Features: CSS Optimiser: Minifies all CSS files and serves CSS directly, eliminating the PHP overhead from css.php. javascript Optimiser: Intelligently defers javascript loading (puts script tags just before on the fly) and combines common javascript files. Also features optional compression with Google Closure Compiler. HTML Optimiser: Based on HELLCAT's Realtime Page Compressor, and adds complete whitespace removal around block and meta elements and removal of unimportant comments. Attachment Optimiser: Intended for FastCGI users only - serves attachment thumbnails and images directly rather than through PHP. All this is done efficiently and on-the-fly - no need for any template edits. Installation: 1. Ensure you have CSS stored on the filesystem and not your database. To check this, go to Settings > Options > Style & Language Settings > Store CSS Stylesheets as Files? and ensure it is set to "Yes". 2. Disable Remote YUI if you have it enabled. To check this, go to Settings > Options > Server Settings and Optimization Options > Use Remote YUI and ensure it is set to "None". 3. Upload the contents of vbsc.zip to your forum root directory via FTP. 4. Ensure the files vbsc.js and vbsc.js.gz in /clientscript/ are writable (chmod). 5. Install product-vbsc.xml as a Product. (Plugins & Products > Manage Products > Add/Import Product) 6. Run Compress javascript and Compress CSS under the vB4: SuperCharged Admin CP section. 7. Check to ensure that all the settings are correct for your forum, as some of the optimisers are likely to conflict with other poorly coded mods, and not all are turned on by default (vB4: SuperCharged > Options). Conflicts: * If you wish to run vBSEO along with the Attachment Optimiser, you must disable Attachment Rewrites under URL Rewrite Settings > Forum URLs. This incompatibility is by design. * If you run vBSEO's Cleanup HTML function, you should choose between it and vBSC's HTML Optimiser. Running both at once is a waste of resources and may create conflicts that would not otherwise exist. Upgrading: 1. Upload the contents of vbsc.zip to your forum root via FTP. (Overwrite the existing files.) 2. Install the new product-vbsc.xml, ensuring you have Allow Overwrite set to Yes. Plugins & Products > Manage Products > Add/Import Product 3. Run Compress javascript and Compress CSS under the vB4: SuperCharged Admin CP section. 1.51: * A minor, optional update involving product-vbsc.xml only. * Fixed conflict between vBSC, vBSEO and certain language/template customisations which prevented the PM notifications from opening a new window when requested. 1.5: * Several changes made to various files - don't forget vbsc.zip when updating. * The javascript Optimiser will now function properly without the Common javascript Cache enabled, for those of you more concerned about download size than http requests * As I've found disabling the Common javascript Cache can take 500ms off the rendering time in Firefox, it is no longer enabled by default. * Fixed Facebook Connect. * Fixed compatibility with certain types of Adsense ads * Fixed loadvBCss inline javascript calls being incorrectly left alone, screwing up nested CMS Sections among other things. * Fixed the removal of the space between "by" and the username in the last post column with the HTML optimiser enabled. * Restored modification date check on vbsc.js 1.4: * Several changes made to various files - don't forget vbsc.zip when updating. * Google Closure Compiler appears to be working again, so you can re-enable that. * Fixed error spam and even fatal errors when importing products, possibly at the expense of compatibility with YAFB, but who needs that now anyway? * Improved inline javascript regexes, fixing several VSa mods, and probably others too. * Improved descriptions of some settings. * HTML Optimiser is no longer on by default (it's pretty resource heavy and pointless). * Fixed hard-coded /admincp/ reference in the CSS Auto-Compress hook. 1.3: * Several changes made to vbsc.php - don't forget vbsc.zip when updating. * Disable Google Closure Compiler if you have it enabled as it no longer works and I'm not sure why yet. * The CSS optimiser now overwrites the existing CSS files with the minified equivalents, reducing the amount of regex guesswork needed. * Fixed error appearing on the login page with the CSS optimiser enabled. * Tested with [AJAX] - Advanced Forum Statistics 1.2: * Changes made to various files - don't forget vbsc.zip when updating. * Added Advanced Attachment Optimiser for img tags (skips attachment.php altogether rather than simply adding a redirect) and improved the original one (designed to be run together). * The DIR constant is now used throughout vBSC. * Fixed style00000 bug on redirect pages - now defaults to style id 1. * Fixed strange bug in the CSS Optimiser where in some circumstances, css.php style URLs (with commas) would be used in direct links, breaking everything. * Removed a pretty pointless check on the modification date of vbsc.js (due to issues). You'd have to be an idiot not to run compress css/js after updating vBulletin 1.1: * Changes made to various files - don't forget vbsc.zip when updating. * No longer works on vBulletin 4.0.0 - supports 4.0.1 only. * Removed common css cache - vBulletin's new "-rollup" system only results in a couple of extra requests and less conflicts. * Added support for new LTR/RTL vbulletin_css folders to all elements of the CSS Optimiser. * Improved support for obscure ways of including CSS that some mods may use. * Fixed unnecessary errors when some javascript files are not present. * The appropriate DIR constant is now used when including vbsc_global.php, hopefully fixing the invalid argument supplied for foreach() error. * Fixed bug in Compress javascript for forum-only vBulletin - file_get_contents(./clientscript/). * Fixed CSS Optimiser incompatibility with Yay! Another Facebook Bridge, which for some reason breaks write_style_css_directory(). * CSS Optimiser now uses write_style_css_directory() rather than the full build_style() function. 1.01: * Changes made to various files - don't forget vbsc.zip when updating. * Fixed compatibility with child styles. * Improved javascript and CSS Optimiser error messages. 1.0: * Changes made to various files - don't forget vbsc.zip when updating. * Fixed bug in the javascript Optimiser where the type attribute was required on a script tag - some mods leave this out or put it after src. * The monolithic vbsc.js file is now optional, although enabled by default (under the setting Common javascript Cache). Many people's problems seem to be related to it, and there isn't much difference without it, as long as the loading deferral is still there. * The CSS files showthread.css, postbit-lite.css, postbit.css and forumdisplay.css are no longer included in the common CSS cache. This fixes a conflict with Abe1's Post Thank You Hack, along with other incompatibilities. The vBSC CSS hacks that were necessary due to conflicting rules in these files have also been removed. * The CSS Files and JS Files settings, along with some other things, have been moved to includes/vbsc_global.php. Due to this, uninstalling before upgrading is no longer strictly necessary. * Greatly improved the details given by the javascript Optimiser fallback warning and steps to take to get it to disappear for people having issues. * Fixed compatibility with the Forum-only version of vBulletin. * Added some Blog files to the common javascript cache. * vBSC will now detect if you have the CMS or Blog products disabled and skip caching their javascript files as necessary. * Improved descriptions of admin settings. ONLY if you wish to use the Attachment Optimiser, something similar to this is needed in your server config (nginx):
