Uploading Server to Google App Engine Node Js

Create a Node.js app in the App Engine flexible environment

Region ID

The REGION_ID is an abbreviated lawmaking that Google assigns based on the region y'all select when you create your app. The code does not stand for to a country or province, fifty-fifty though some region IDs may appear like to commonly used country and province codes. For apps created after February 2020, REGION_ID.r is included in App Engine URLs. For existing apps created before this date, the region ID is optional in the URL.

Larn more than about region IDs.

This quickstart shows you how to create a small App Engine app that displays a short message.

Before yous begin

1. Sign in to your Google Cloud account. If y'all're new to Google Cloud, create an account to evaluate how our products perform in real-world scenarios. New customers also get $300 in costless credits to run, test, and deploy workloads.

2. In the Google Cloud Panel, on the projection selector folio, select or create a Google Cloud project.

   Become to project selector

3. Brand certain that billing is enabled for your Cloud project. Learn how to check if billing is enabled on a project.

4. Enable the Cloud Build API.

   Enable the API

5. Install and initialize the Google Cloud CLI.

6. In the Google Cloud Console, on the project selector page, select or create a Google Deject project.

   Get to project selector

7. Make sure that billing is enabled for your Cloud project. Learn how to bank check if billing is enabled on a projection.

8. Enable the Cloud Build API.

   Enable the API

9. Install and initialize the Google Cloud CLI.

Boosted prerequisites

1. 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 desire to locate your App Engine application.

2. Install the post-obit prerequisites:

   • Download and install Git.
   • Ready your environs for Node.js development.

App Engine locations

App Engine is regional, which ways the infrastructure that runs your apps is located in a specific region, and Google manages information technology then that it is available redundantly across all of the zones within that region.

Meeting your latency, availability, or durability requirements are main factors for selecting the region where your apps are run. Yous can generally select the region nearest to your app'due south users, only you should consider the locations where App Engine is available as well as the locations of the other Google Deject products and services that your app uses. Using services across multiple locations can touch your app's latency as well as its pricing.

You cannot change an app's region subsequently y'all gear up it.

If you already created an App Engine application, you can view its region past doing one of the post-obit:

• Run the gcloud app describe control.

• Open the App Engine Dashboard in the Deject Console. The region appears near the top of the page.

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

Download the Hi Earth app

We've created a simple How-do-you-do Earth app for Node.js so you lot can apace go a experience for deploying an app to the Google Cloud.

1. Clone the Howdy World sample app repository to your local car.

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

   Alternatively, you lot can download the sample as a zilch file and excerpt information technology.

2. Change to the directory that contains the sample code.

                   cd nodejs-docs-samples/appengine/hello-earth/flexible                              

Run Hullo Globe on your local auto

1. Install dependencies for this projection.

                   npm install                              

   Or if you are using Yarn.

                   yarn install                              

2. Run the offset script.

                   npm commencement                              

   Or if you are using Yarn.

                   yarn get-go                              

3. View your app in your web browser.

   • If yous are using Cloud Shell, in the toolbar, click Web Preview and select Preview on port 8080 instead.

   • If you lot are not using Cloud Shell, enter the following address:

   http://localhost:8080

The Hullo Earth message from the sample app displays on the page. In your last window, printing Ctrl+C to exit the spider web server.

Deploy and run Hullo World on App Engine

To deploy your app to the App Engine flexible environment:

1. Deploy the Hello Earth app by running the following control from the hello-earth/flexible directory:

   gcloud app deploy

   Learn most the optional flags.

   Mutual gcloud command flags

   • Include the --version flag to specify an ID that uniquely identifies that version of your app, otherwise ane is generated for you lot. Instance: --version [YOUR_VERSION_ID]
   • Include the --project flag to specify an alternate Cloud projection ID to what yous initialized as the default in the gcloud tool. Example: --project [YOUR_PROJECT_ID]

   Example:

   gcloud app deploy --version pre-prod-5 --project my-sample-app

   To larn more than about deploying your app from the control line, encounter Testing and Deploying Your App . For a list of all the control flags, run into the gcloud app deploy reference.

2. Launch your browser to view the app at https://PROJECT_ID.REGION_ID.r.appspot.com

   gcloud app browse

   where PROJECT_ID represents your Google Deject projection ID.

This time, the page that displays the Hullo World message is delivered by a web server running on an App Engine example.

Congratulations! You've deployed your outset Node.js app to App Engine flexible environment!

If you encountered any errors deploying your awarding, check the troubleshooting tips.

Encounter the post-obit sections for data about cleaning up as well every bit links to possible adjacent steps that you lot can take.

Make clean up

To avert incurring charges, you can delete your Cloud project to terminate billing for all the resource used inside that project.

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

   Get to Manage resource

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

What's next

Learn the whole platform

Now that y'all know what it'southward similar to develop and deploy App Engine apps, yous tin explore the remainder of Google Cloud. You already accept the Google Deject CLI installed which gives you the tools to interact with products like Deject SQL, Cloud Storage, Firestore, and more.

For a guided walkthrough that teaches you how to create an app that uses the entire platform, non just App Engine, cheque out our quickstart on creating the Bookshelf app.

Acquire nearly the App Engine flexible surround

Here are some topics to help go along your learning about App Engine.

• An overview of App Engine
• How requests are routed
• How requests are handled
• How instances are managed

Howdy Globe code review

Hi World is the simplest possible App Engine app, as it contains only i service, has but i version, and all of the code is located within the app's root directory. This section describes each of the app files in particular.

app.js

The app.js file contains the JavaScript code to first a server and reply to requests.

The post-obit lawmaking responds to requests from spider web clients past displaying the 'Hello Globe' message, via a server that runs on port 8080.

app.yaml

The app.yaml file describes an app's deployment configuration:

Here, app.yaml specifies the runtime used past the app, and sets env: flex, specifying that the app uses the flexible environs.

• For more information on how the Node.js runtime works, come across The Node.js runtime.

• For more details nigh how to design your app to take reward of versions and services, see An overview of App Engine.

• For more details about the configuration settings for App Engine, see Configuring your app with app.yaml.

parcel.json

packet.json is used to specify app dependencies, node version, and app startup.

In the preceding example, the packet.json file specifies that the app uses Node.js v12.xx.0 or later, depends on express, and that node app.js is used to starting time the app. The Node.js version you specify in your app can use the version specified or after. For more details about how to install and run your app, encounter the Node.js runtime documentation.
