I intend to compress/Minfy my HTML output so that the html size becomes less which increases the performance . 

 

eg : view-source:https://docs.adobe.com/content/help/en/experience-manager-dispatcher/using/getting-started/dispatcher-install.html 

lots of white space if you see the source code .

    Hi @ebin_aby ,

     

    HTML compression needs to be implemented on your web server. If its Apache, you can use mod_deflate module. Please follow [1] for steps and [2] for documentation

    The following document may be helpful:

    https://docs.adobe.com/content/help/en/experience-manager-64/developing/introduction/clientlibs.html#UsingPreprocessors

     

    Try rebuilding the clientlibs via File System, as per: https://helpx.adobe.com/ca/experience-manager/kb/How-to-force-a-recompilation-of-all-Sling-scripts-jsps-java-sightly-on-AEM-6-4.html

     

    * Moreover, what kind of errors do you see in the error.log file?

      Hi @ebin_aby 

      AEM OOTB doesn't have default option to minify html. 

      Minification option is available for css /js by default . 

       

      If you need to minify html output, you need to use html compression library which is custom implementation. 

      There are many plugins are available to achieve the minification of html. One of the simplest is 

      maven  html compression tag library, which you can import and use it for html minification. 

      https://mvnrepository.com/artifact/com.googlecode.htmlcompressor/htmlcompressor/1.4

      Or 

      You can achieve the same towards apache layer as well. mod-pagespeed is one of the plugin which includes minification/compression of html along with other features which contribute to page performance. You can find more details in below article.

          Hi,

          I see mod_deflate is for compression not minification. Is there a recommended alternative for minifying the HTML files? We have found many references to mod_pagespeed but the last version of the module was released in 2018 and there is no active development (https://groups.google.com/g/mod-pagespeed-discuss/c/dKz1KKjEII0).

          I don't think so, removing whitespaces would make much difference in performance. If you have large pages in sizes then it may but for small pages, it may not.
