When the request url is lets say /content/myapp.html and sling:resourceType of myapp is /apps/myapp/components/myappcomponent.

Scenario 1: under myappcomponent, lets say there are following files myappcomponent.html, myappcomponent.esp

In this case myappcomponent.html will be rendered.

Scenario 2: under myappcomponent, lets say there are following files myappcomponent.esp

In this case myappcomponent.esp will be rendered.

Scenario 3: under myappcomponent, lets say there are following files myappcomponent.json,myappcomponent.js,myappcomponent.txt

what will be rendered in this case????????

Question: is there any other fallback extensions which are supported in Sling if there is no applicable extension which is requested?

@manjunathdj I searched SLING and ADOBE Documentations as well, not found it anywhere.

@prashanthal - Are you looking to render Json or JS files?

@prashanthal Please see below link for an example. Ideally combination of selector and extensions takes the highest priority. Same has been explained in this link:
https://aemgeeks.wordpress.com/2017/07/31/sling-resource-resolution-sling-request-processing/#:~:text=Then%20the%20order%20of%20preference%20would%20be%20(10)%20%E2%80%93%20(9)%20%E2%80%93%20(6)%20%E2%80%93%20(8)%20%E2%80%93%20(7)%20%E2%80%93%20(5)%20%E2%80%93%20(3)%20%E2%80%93%20(4)%20%E2%80%93%20(2)%20%E2%80%93%20(1).

@krati_garg This example is demonstrating only .html and .esp as I mentioned in my query, not others.

@prashanthal

selectors have maximum priority and the more selectors are matched the highest the priority. If selectors are not matched then the extension gets priority.

It follows the below pattern:

{resourceTypeLabel}.{selectorString}.{requestMethod}.{requestExtension}.{scriptExtension}

https://experienceleague.adobe.com/docs/experience-manager-65/developing/platform/sling-cheatsheet.html?lang=en

for more details ref. https://issues.apache.org/jira/browse/SLING-387

Hope this helps.

For Scenario 3: I believe none of them will render.

As far as I remember jsp,esp,html are suppported.

for all other than html - the suffix is added to the script name

eg:

/myappcomponent.js.esp

/myappcomponent.json.esp

/myappcomponent.txt.esp

Have you already tried it out? 🙂

@joerghoh Yup, I already tried it, getting 404.

You will get a 404 if

* you are requesting a non-existing content node

* if a resourcetype is given but does not exist
