Can we async or defer referencing Client side Libraries

[JakeCham]

Hi Team,

I'm trying to load a client library using a helper template provided by AEM.

<sly data-sly-use.x="/libs/granite/sightly/templates/clientlib.html">

      <sly data-sly-call=${clientlib.js @@categories='x'}/>

</sly>

Do we need to still defer this if so how we can do it ?

Thanks

Hi @JakeCham 

As of now this is not supported on any version of AEM as per Adobe. Few months back I too reached out to Adobe with similar query and they asked us to do some custom implementation on our own as they do not have any such implementation available OOTB.
Please refer https://github.com/nateyolles/aem-clientlib-async for reference.

Thanks,
Asutosh

Hi Asutosh_Jena_ 

Thank you for the response. Tried the above solution where dependencies and embedded categories are not building as clientlibs .Only specified categories are coming when we used newly created template ''/apps/clientlib -async/sightly/templates/clientlib.html''. Any input highly appreciated.

@JakeCham ,

If you want to add any attribute in the clientlib load syntax, it needs to be customized.

Please refer to the below link to add 'defer' or 'async' in clientlib.

Hello,

That's correct, you have to do custom implementation. I have done similar via sightly and biding the config properties from clientlibraries node to process accordingly.

share if you need more details.

THanks!!

@JakeCham there are two scenarios.

Scenario 1, where the client library has no dependencies

With scenario one, simple implementation with no dependencies, you can simply call the absolute path to the client library, for example:

<script defer src="/etc.clientlibs/my-site/clientlibs/clientlib-site.js"></script>

Scenario 2, the client library has dependencies

then like what the others say, nateyolle's solution looks like an option.
