How to recompile clientlibs and invalidate cache?

The clientlibs in AEM consists of JS and CSS and in some instances they get cached; which as would be obvious; causes issues.
To remove this cache and rebuild the clientlibs, following link is quite useful:

<domain-name>/libs/granite/ui/content/dumplibs.rebuild.html

There are individual buttons to invalidate cache and rebuild the libraries on this page.
For faster access, there is a query parameter for each process that can be appended to the URL:

Invalidate Caches: ?invalidate=true
Rebuild Libraries: ?rebuild=true

Please note for AEM 6.1, certain issues have been reported and solution provided. You can check the following link if you face an issue:

How to access all AEM logs via Felix Console

Sometimes, we need to get all AEM logs but might not have SSH access to the server.

In such scenarios, we can rely on the Felix Console.

1) Go to <domain>/system/console/status-slinglogs

The screen rolls automatically when the log files get updated for the current day.

However, all log files can also be downloaded via 4 options:

1) Download As Text

This will open a text document: <domain>/system/console/status-slinglogs.txt that has content from all log files

2) Download As Zip

This will download a zip file named 'status-slinglogs.zip' on your machine.

All system and custom log files can be extracted from this zip file.

3) Download Full Text

This will open a text document: <domain>/system/console/status-slinglogs/configuration-status-<date>.txt that has information about all bundles and content from all log files

4) Download Full Zip

This will download a zip file named 'configuration-status-20170503-050248.zip' on your machine.

All bundles details, config details and log files can be extracted from this zip file.

How to avoid AEM generated wrapping divs

'cq:htmlTag' can be used to manipulate the wrapper divs that are generated by default by AEM.

This can be added as an nt:unstructured node under the component.

Following properties need to be defined for this node:

1. cq:tagName : The tag that needs to be generated for the component (div, span etc.)

2. class : The CSS class names that would be added to the tag generated as per 1.

3. id : The id of the tag that would be added to the tag generated as per 1.

Either of 2 or 3 or both can be used. However, if neither 'id' nor 'class' is defined, the tag doesn't get generated and AEM behaves in the default manner generating it's own wrapping div.

As an example,

This will generate the component as -

    <div id="component-id" class="grid-tile">
    .

    .

    </div>

How to disable link checker for selective links

Several times in a project, there is a requirement that the OOTB link checking in AEM needs to be disabled for specific links.

There are 2 options to achieve this:

x-cq-linkchecker="valid"  : This will make the linkchecker mark the link as valid.

x-cq-linkchecker="skip"  : This will make the linkchecker skip the link.

These tags should need to be added on the <a> tag directly, for example:

<a href="xxx" x-cq-linkchecker="skip">Link</a>
