Link Rewriting

I am trying to make a link rewriter which will open all external links(eg: google.com, facebook.com) in a new tab by default and all internal links(/content/....) in same tab. 

I am not sure how should I proceed for that. Need help

Hi @ronnie09 ,

We use Siglhty for Markup Rendering, Most of the manipulation or condition checks we do in JavaScript Code or Java Backend Code.

 

You can proceed with the below approach:

  • In Sling Model, When we are checking for an internal( appending .html) link or external link and passing it to sightly.
  • We can also pass flags true for internal and false for external to sightly.
  • In Sightly use the data-sly-test tag for checking the condition, If it is true, Provide target ="_self", and for false provide target="_blank".

Hope this could help you !!!

Thanks

Shiv

Here here is the example

https://github.com/arunpatidar02/aem63app-repo/blob/master/java/CustomLinkChecker.java

Note: This is a global link rewriter, please restrict the link rewriter to your project itself using rewrite config.

e.g. https://adobe-consulting-services.github.io/acs-aem-commons/features/utils-and-apis/static-reference-rewriter/index.html

      Yes java is enough , you need to check if link is external and there is no target attribute and add target attribute at https://github.com/arunpatidar02/aem63app-repo/blob/f99cdbdd649423d8ee4bdbeafe0e840bdf99c97c/java/CustomLinkChecker.java#L83 

       

      You also configure the pipeline at /apps/yourapp/config/rewriter, there you need to mentioned the pipeline name and path and other properties.

       

      Below is the example of non global CustmLinkChecker

        Hi @ronnie09 

           Another option to could be you write your own Transformer (org.apache.sling.rewriter.Transformer) to update the links accordingly. However I still prefer doing it in sightly.

         

        Thanks
