Azure App Service deploy version 4 not showing node 20 in runtime stack

Question

I am upgrading my Node.js application to version 20 and have integrated an Azure pipeline for deployment.

In the Azure portal, under Settings > Configuration > General Settings > Stack Settings, I updated the Node.js version to 20. However, in the Azure pipeline, I am using the Azure App Service Deploy task to deploy my back-end. In this task, I am u

nable to find Node.js 20 listed in the runtime stack options.

If I set the Node.js version to 20 in the portal configuration but do not update it in the Azure App Service Deploy task, the runtime stack reverts to Node.js 18 during deployment.

Hi Ronak Patel
Welcome to the Microsoft Q&A Platform!
You're encountering an issue where the Azure App Service Deploy task in your pipeline doesn't list Node.js 20 as an available runtime stack, causing deployments to revert to Node.js 18.
Update the Azure App Service Deploy Task:

Ensure you're using the latest version of the Azure App Service Deploy task in your pipeline, as older versions may not support Node.js 20.

Set the Node.js Version Using Azure CLI.

Incorporate an Azure CLI task in your pipeline to explicitly set the Node.js version to 20 for your App Service.

- task: AzureCLI@2
  inputs:
    azureSubscription: '<YourAzureSubscription>'
    scriptType: 'bash'
    scriptLocation: 'inlineScript'
    inlineScript: |
      az webapp config set --resource-group <ResourceGroupName> --name <AppName> --linux-fx-version "NODE|20"

Replace <YourAzureSubscription>, <ResourceGroupName>, and <AppName> with your actual Azure subscription, resource group, and app name.

Add the WEBSITE_NODE_DEFAULT_VERSION setting to your App Service to specify the Node.js version.

- task: AzureAppServiceSettings@1
  inputs:
    azureSubscription: '<YourAzureSubscription>'
    appName: '<YourAppName>'
    appSettings: |
      [
        {
          "name": "WEBSITE_NODE_DEFAULT_VERSION",
          "value": "20"
        }
      ]

This configuration ensures that your App Service uses Node.js version 20.

Confirm that Azure App Service in your region supports Node.js 20.

As of November 2024, Azure App Service has announced support for Node.js 20.
If the Azure App Service Deploy task doesn't list Node.js 20, consider raising a support ticket or providing feedback to Microsoft to address this discrepancy.
