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

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.
