Basic commands and stuff to remember when working on AEM projects

Commands to do maven build to install the stuff from code to AEM instances:

mvn clean install -PautoInstallPackage -Daem.host=localhost -Daem.port=4502 -Dvault.password=admin

mvn clean install -PautoInstallBundle -Daem.host=localhost -Daem.port=4502 -Dvault.password=admin

Note: Port number is depending on what port you are running AEM instance. In the above commands, I gave 4502 as some example.

Command to open the AEM instance in debug mode:

java -Xdebug -Xnoagent -Djava.compiler=NONE -Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=30303 -XX:+HeapDumpOnOutOfMemoryError -XX:MaxPermSize=512M -Xmx1024m -jar cq-author-p4502.jar -p 4502 -verbose -nofork

Note: The above marked one in the red is port number on which debug instance runs.
       
In Eclipse, open the debug mode and under Run select debug configurations and from there select Remote Java Application --> right click --> New --> give port number same as above marked in the red.

Command to start the AEM Author instance:

java -Xmx1024m -jar cq-author-4502.jar

Note: Xmx means  maximum allocation of the RAM for the aem service

java -Xms1024m -jar cq-author-4502.jar

note: Xms means  Minimum allocation of the RAM for  the arm service

Link Checker Transformer  and it's role in validating the page links:
Link checker Transformer can be used to disable or enable the external links validation on the content pages. It is up to us to decide on which one we have to choose from options like Disable entire Link checker transformer, mark entire links are valid or skip the validation of the link.

To Disable the entire Link Checker Transformer:
Go to http://localhost:4502/system/console/configMgr  and search for Day CQ Link Checker Transformer and in that select the Disable Checking option.

For certain Domain we can disable the link by adding overriding pattern:
For Example Link Check Override patterns: if we add ^hello/, then any external link starting with System will not be checked. You can add additional pattern to it.

How to make sure some links are always valid or always skip?
We can use x-cq-linkchecker="valid" parameter in anchor tags to make always make that particular link as valid or
x-cq-linkchecker="skip" parameter in anchor tags to make always make that particular link as skip, since it even didn't check the links.

AEM CHEAT SHEET:

HOW TO CHECK THE USAGE OF THE COMPONENT IN THE WEBSITE?
1. In local instance or any AEM environment go 
    to http://localhost:6502/libs/cq/search/content/querydebug.html
2. Start building the query something like this:
    path=/content/<Specific site>
    property=sling:resourceType
    property.value=<project-name>/components/content/text
            Note: we can skip /app and directly give the path of component as stated above.
3. Hit search
