Disable Azure function programmatically uisng javascript

Question

have a scenario while running the app I have to disable/enable a particular function. I'm using JavaScript SDK. Please suggest.

Answer 1

@Shweta , thank you for reaching out to us. Let's consider we have an Azure Function App with 2 functions: HttpTrigger1 and BlobTrigger1 and that we want to disable the HttpTrigger1 function. This can be achieved by going to the Configuration tab of our Function App and add a new boolean app setting named using this pattern:

AzureWebJobs.HttpTrigger1.Disabled  

Now, set it's value to true, and you will see that it is disabled. Consequently, to enable the Function back, you can make AzureWebJobs.HttpTrigger1.Disabled value false. Further, if you want to disable this programmatically, you can use PowerShell or Azure CLI. Below is the script to set App Settings in your App Service:

$site = Get-AzWebApp -Name foo-app  
$oldSettings = ($site.SiteConfig.AppSettings | % { $h = @{} } { $h[$_.Name] = $_.Value } { $h })  
  
$newSettings = @{ AzureWebJobs.HttpTrigger1.Disabled  = true }  
  
Set-AzWebApp -ResourceGroupName foo-rg -Name foo-app -AppSettings ($oldSettings + $newSettings)  

The best way AFAIK to achieve this is to use PowerShell Function App for running above scripts (since it has in-built support for PowerShell) and calling PowerShell Function App endpoint from your JavaScript code. I would also recommend you to watch Using PowerShell Modules in Azure Functions for more insights about Azure PowerShell functions. Let me know if you have further questions.
