How to run a specific HTL Snippet in Dev and Stage Instance only and not in prod

[Nitesh-Chavan]

Hello Community Members, 

Good Day!

I have a use case, I have a HTL file (present in the Dev, Stage and Prod instances) in which I have a particular HTL Snippet I want to get executed in AEM Stage and Dev instances only (Including Author and Publisher) and strictly not on the Production instance. 

Is there a way to code this logic in HTL so that the HTL Snippet will only gets executed on the Dev and Stage instance. 

Thank You.

Hi @arunpatidar 

Thanks for sharing the above piece of information, however we can see the "slingSettingsService" is deprecated. 

As mentioned by the Author of the post you have shared I will try the new method suggested by the author.

Hi @Nitesh-Chavan ,

Yes, you can control execution of HTL code based on the AEM environment (Dev, Stage, Prod) by making use of run modes and exposing them via a Sling Model or Use-API class to your HTL.

public class EnvironmentCheck extends WCMUsePojo {

    private boolean isDevOrStage;

    @Override
    public void activate() {
        SlingSettingsService slingSettings = getSlingScriptHelper().getService(SlingSettingsService.class);
        Set<String> runModes = slingSettings.getRunModes();
        isDevOrStage = runModes.contains("dev") || runModes.contains("stage");
    }

    public boolean isDevOrStage() {
        return isDevOrStage;
    }
}

<data-sly-use.envCheck="com.example.core.utils.EnvironmentCheck" />

<sly data-sly-test="${envCheck.devOrStage}">
  <p>This is shown in Dev/Stage only.</p>
</sly>

• SlingSettingsService.getRunModes() checks current AEM run modes.
• You expose a flag isDevOrStage to HTL.
• HTL renders the block only if the run mode is dev or stage.

Set run modes like this in your instance: -Dsling.run.modes=env

Try this and let me know if it works.

I will check this and I will get back to you on it.

Thank You.

Thanks for the information - I wasn’t aware it was deprecated. I’ll check that.
