Quickstart for Node.js in the App Engine Standard Environment

Region ID

The REGION_ID is a code that Google assigns based on the region you select when you create your app. Including REGION_ID.r in App Engine URLs is optional for existing apps and will soon be required for all new apps.

To ensure a smooth transition, we are slowly updating App Engine to use region IDs. If we haven't updated your Google Cloud project yet, you won't see a region ID for your app. Since the ID is optional for existing apps, you don't need to update URLs or make other changes once the region ID is available for your existing apps.

This quickstart shows how to deploy a sample app on App Engine. If you want to learn about coding an app for App Engine, see Building an App.

Costs

There are no costs associated with running this guide. Running this sample app alone does not exceed your free quota.

Before you begin

Before running and deploying this quickstart, install the Cloud SDK and then set up a Cloud project for App Engine:

  1. Download and install Cloud SDK:

    Download the SDK

    Note: If you already have the Cloud SDK installed, update it by running the following command:

    gcloud components update
    
  2. Create a new project:

    gcloud projects create [YOUR_PROJECT_ID] --set-as-default
    

    Verify the project was created:

    gcloud projects describe [YOUR_PROJECT_ID]
    

    You see project details that might look like the following:

    createTime: year-month-hour
    lifecycleState: ACTIVE
    name: project-name
    parent:
    id: '433637338589'
    type: organization
    projectId: project-name-id
    projectNumber: 499227785679
    
  3. Initialize your App Engine app with your project and choose its region:

    gcloud app create --project=[YOUR_PROJECT_ID]
    

    When prompted, select the region where you want your App Engine application located.

  4. Make sure billing is enabled for your project. A billing account needs to be linked to your project in order for the application to be deployed to App Engine.

    Enable billing

  5. Install the following prerequisites:

App Engine locations

App Engine is regional, which means the infrastructure that runs your apps is located in a specific region and is managed by Google to be redundantly available across all the zones within that region.

Meeting your latency, availability, or durability requirements are primary factors for selecting the region where your apps are run. You can generally select the region nearest to your app's users but you should consider the location of the other Google Cloud products and services that are used by your app. Using services across multiple locations can affect your app's latency as well as pricing.

App Engine is available in the following regions:

  • northamerica-northeast1 (Montréal)
  • us-central (Iowa)
  • us-west2 (Los Angeles)
  • us-east1 (South Carolina)
  • us-east4 (Northern Virginia)
  • southamerica-east1 (São Paulo)
  • europe-west (Belgium)
  • europe-west2 (London)
  • europe-west3 (Frankfurt)
  • europe-west6 (Zürich)
  • asia-northeast1 (Tokyo)
  • asia-northeast2 (Osaka)
  • asia-east2 (Hong Kong)
  • asia-south1 (Mumbai)
  • australia-southeast1 (Sydney)

You cannot change an app's region after you set it.

If you already created an App Engine application, you can view the region by doing either of the following:

This quickstart demonstrates a simple Node.js application written with the Express.js framework.

Download the sample code

Use our simple Hello World app for a quick overview of deploying a web service on App Engine. Follow these steps to download the code to your development environment:

  1. Download the Node.js sample app repository:

    Cloud Shell

    Clone the Git repository:

    git clone https://github.com/GoogleCloudPlatform/nodejs-docs-samples

    Local machine

    Download the repository as a ZIP file and extract it.

    Alternatively, if you use Git, clone the repository with the following command:

    git clone https://github.com/GoogleCloudPlatform/nodejs-docs-samples
  2. Change to the directory that contains the Hello World app:

    cd nodejs-docs-samples/appengine/hello-world/standard
    

Run Hello World locally

  1. Install dependencies for the project:

    npm install
    
  2. Start the HTTP server:

    npm start
    
  3. View the app in your web browser:

    Cloud Shell

    In the Cloud Shell toolbar, click Web preview Web preview and select Preview on port 8080.

    Local machine

    Point your web browser to http://localhost:8080

    You can see the message Hello, world! displayed on the page.

  4. Stop the HTTP server by pressing Ctrl+C in the terminal window.

Deploy and run Hello World on App Engine

  1. Deploy the Hello World app on App Engine by running the following command from the hello-world/standard directory:

    gcloud app deploy
    
  2. View the live app at https://PROJECT_ID.REGION_ID.r.appspot.com:

    gcloud app browse
    

The message Hello, world! is now delivered by a web server running on an App Engine instance.

Congratulations! You've successfully deployed a Node.js web service on App Engine!

Clean up

If you want to continue learning about App Engine, you can keep your Cloud project and follow along with Building an App.

Alternatively, you can delete your Cloud project to stop billing for all the resources used within that project.

  1. In the Cloud Console, go to the Manage resources page.

    Go to the Manage resources page

  2. In the project list, select the project that you want to delete and then click Delete .
  3. In the dialog, type the project ID and then click Shut down to delete the project.
