Retrieve latest content from AEM Repository

Hi guys,

I got a requirement to be able to retrieve content from AEM repository on a web page once it is published, ie. retrieve the latest publish content.

Using the JavaScript Use API is somehow possible as well, however once the latest content published it won't display directly on the client/user machine as the dispatcher cache the content and we will need to flush the dispatcher cache to be able to retrieve the new content.

Doing that is somehow ineffective if we have a large number of content inside the repository already.

any sorts of suggestions / best practice how to do it?

Thanks!

Hi,

I read your question, but I don't understand it. I understood that you want to fetch the latest published content, but the second paragraph doesn't make sense to me. Can you rephrase your question?

Thanks,

Jörg

I agree with Joerg - your question is not clear. You want to query latest published content. What purpose is this for? Do you want to track pages that are published for reporting purposes?

Hi Joerg,

Thanks for the reply Joerg!

What I wanted to say on the second paragraph is basically one of the possibility to fetch the latest published content from the JCR. However it is not a really good solution (ineffective)  as it is using the JS Use API which is a server-side language and potentially put a heavily load on the server.

so to summarise it, the question is basically, is there any other solutions that we can implement to fetch the latest published content so that the user can get suggestions on the latest published article once the article is published?

the purpose is not to track pages that are being published, the purpose is to promote / display the latest published articles to users.

Yes, you can achieve it. But in this case your this particular request has to pass from dispatcher without caching.

gauravb10066713​ has already mentioned few recommended approach which is used to tackle this like SDI, Ajax

I don't have the details of your requirement but on a high level, you will have to create an endpoint in your aem (using servlet). These endpoint will be responsible for sending response with updated content. From front-end you will be requesting these endpoint and consume the response.
