A servlet to Query Components inside your apps folder.

If you want to get your list of components inside your project apps folder in the form of json response, then here's a servlet for you.

The servlet is registered at path - /bin/generate/componentsreport  to which you need to pass your project folder path (default is /apps) as a query-param and it will output the list of components (their name and path) as a json response.

What this servlet is doing is - it is forming a Predicate Map of Query having the path (apps path from the input you provide) and node type (cq:Component) and using it in QueryBuilder API and fetching the results in form of component paths.

Further it is processing the hits (components path) from the search result to form the json response which you can consume by dong an ajax call.

This is the servlet for it-

Below is the sample url to call this servlet by passing apps folder path-
http://localhost:4502/bin/generate/componentsreport?comppath=/apps/weretail

And this is the screenshot of the response by hitting above url-
