In this quickstart, you learn how to create and deploy your first Node.js (Express) web app to Azure App Service. App Service supports various versions of Node.js on both Linux and Windows.
This quickstart configures an App Service app in the Free tier and incurs no cost for your Azure subscription.
This video shows you how to deploy a Node.js web app in Azure.
[!VIDEO c66346dd-9fde-4cef-b135-47d3051d5db5]
The steps in the video are also described in the following sections.
:::zone target="docs" pivot="development-environment-vscode"
- Have an Azure account with an active subscription. If you don't have one, you can create an account for free.
- Install Node.js LTS. Run the command
node --versionto verify that Node.js is installed. - Install Visual Studio Code.
- Install the Azure App Service extension for Visual Studio Code.

:::zone target="docs" pivot="development-environment-azure-portal"
- Have an Azure account with an active subscription. If you don't have one, you can create an account for free.
- Install Node.js LTS. Run the command
node --versionto verify that Node.js is installed. - Have an FTP client, such as FileZilla, to transfer files to App Service.
::: zone-end
In this step, you create a basic Node.js application and ensure it runs on your computer.
Tip
If you already completed the Node.js tutorial, you can skip ahead to Deploy to Azure.
-
Create a Node.js application by using the express application generator, which is installed by default with Node.js and npm.
npx express-generator myExpressApp --view ejs
If this is the first time you've installed the generator, npx asks you to agree to the installation.
-
Change to the application's directory and install the npm packages.
cd myExpressApp && npm install
-
Update dependencies to the most secure version.
npm audit fix --force
-
Start the development server with debug information.
DEBUG=myexpressapp:* npm start -
In a browser, navigate to
http://localhost:3000. You should see something like this::::image type="content" source="media/quickstart-nodejs/express.png" alt-text="Screenshot of an Express application running in a browser.":::

Before you continue, ensure that you have all the prerequisites installed and configured.
Note
For your Node.js application to run in Azure, it needs to listen on the port provided by the PORT environment variable. In your generated Express app, this environment variable is already used in the startup script bin/www. (Search for process.env.PORT.)
:::zone target="docs" pivot="development-environment-vscode"
-
In the terminal, ensure you're in the myExpressApp directory, and then start Visual Studio Code with the following command:
code . -
In Visual Studio Code, in the Activity Bar, select the Azure logo.
-
Ensure that you're signed in with your Azure account.
[!div class="nextstepaction"] I ran into an issue
-
Right-click App Services and select Create new Web App. A Linux container is used by default.
-
Type a globally unique name for your web app and select Enter. The name must be unique across all of Azure and use only alphanumeric characters (
A-Z,a-z, and0-9) and hyphens (-). -
In Select a runtime stack, select the Node.js version you want. Node 24 LTS is recommended.
-
In Select a pricing tier, select Free (F1) and wait for the resources to be created in Azure.
-
In the popup Always deploy the workspace "myExpressApp" to <app-name>", select Yes. Doing so ensures that, as long as you're in the same workspace, Visual Studio Code deploys to the same App Service app each time.
While Visual Studio Code creates the Azure resources and deploys the code, it shows progress notifications.
-
After deployment is complete, select Browse Website in the notification popup. The browser should display the Express default page.
-
Under Resources, in the subscription that you want to use, right-click App Services, and then select Create New Web App... (Advanced).
-
Select the location that you want to serve your app from. For example, West Europe.
-
Select Secure unique default hostname.
-
Select Create a new resource group, and then enter a name for the resource group, such as AppServiceQS-rg.
-
Type a globally unique name for your web app and then select Enter. The name must be unique across all of Azure and use only alphanumeric characters (
A-Z,a-z, and0-9) and hyphens (-). -
Select the Node.js version you want. Node 24 LTS is recommended.
-
Select Windows for the operating system.
-
Select Create new App Service plan, enter a name for the plan (such as AppServiceQS-plan), and then select F1 Free for the pricing tier.
-
For Select an Application Insights resource for your app, select Skip for now. Wait for the resources to be created in Azure.
-
In the popup Always deploy the workspace "myExpressApp" to <app-name>", select Yes. Doing so ensures that, as long as you're in the same workspace, Visual Studio Code deploys to the same App Service app each time.
While Visual Studio Code creates the Azure resources and deploys the code, it shows progress notifications.
[!NOTE] After deployment is complete, your Azure app doesn't run yet because your project root doesn't have a web.config file. Follow the remaining steps to generate it automatically. For more information, see You do not have permission to view this directory or page in Configure a Node.js.
-
In Resources in Visual Studio Code, expand the node for the new app, right-click Application Settings, and select Add New Setting:
:::image type="content" source="media/quickstart-nodejs/add-setting.png" alt-text="Screenshot of the Add New Setting command.":::
-
Enter
SCM_DO_BUILD_DURING_DEPLOYMENTfor the setting key. -
Enter true for the setting value.
This app setting enables build automation at deploy time, which automatically detects the start script and generates the web.config file with it.
-
In the App Service explorer, select the Deploy to Web App icon again, and confirm by selecting Deploy again.
-
Wait for deployment to complete, and then select Browse Website in the notification popup. The browser should display the Express default page.

:::zone target="docs" pivot="development-environment-cli"
In the terminal, ensure you're in the myExpressApp directory, and deploy the code in your local folder (myExpressApp) using the az webapp up command:
az webapp up --sku F1 --name <app-name>
az webapp up --sku F1 --name <app-name> --os-type Windows
- If the
azcommand isn't recognized, ensure you have the Azure CLI installed as described in Set up your initial environment. - Replace
<app_name>with a name that's unique across all of Azure. (Valid characters area-z,0-9, and-.) A good pattern is to use a combination of your company name and an app identifier. - The
--sku F1argument creates the web app on the Free pricing tier, which incurs no cost. - You can optionally include the argument
--location <location-name>where<location_name>is an available Azure region. You can retrieve a list of allowable regions for your Azure account by running theaz account list-locationscommand. - The command creates a Linux app for Node.js by default. To create a Windows app instead, use the
--os-typeargument. - If you see the error, "Could not auto-detect the runtime stack of your app," ensure you're running the command in the myExpressApp directory (See Troubleshooting auto-detect issues with az webapp up.)
The command might take a few minutes to complete. While running, it provides messages about creating the resource group, the App Service plan, and the app resource, configuring logging, and doing Zip deployment. It then returns a message that includes the app's URL, which is the app's URL on Azure.
