Quickstart for Node.js in the App Engine standard environment

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 GCP 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. 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 GCP 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 running the gcloud app describe command or opening the App Engine Dashboard in the GCP Console. The region of your App Engine application is listed under http://[YOUR_PROJECT_ID].appspot.com.

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://YOUR_PROJECT_ID.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 GCP project and follow along with Building an App.

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

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

    Go to the Manage resources page

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