Prerequisites

Before you begin, make sure you have the following:

• A Google Cloud project set up
• The Google Cloud SDK installed on your local machine

Setting up a Cloud Build configuration file

To deploy a JavaScript application to Google Cloud using Cloud Build, you need to set up a cloudbuild.yaml file in the root directory of your application. This file defines the build steps and deployment configuration for your application.

Here is an example cloudbuild.yaml file for deploying a simple JavaScript application:

steps:
  # Step 1: Install dependencies
  - name: 'gcr.io/cloud-builders/npm'
    args: ['install']
  
  # Step 2: Build the application
  - name: 'gcr.io/cloud-builders/npm'
    args: ['run', 'build']
  
  # Step 3: Deploy to Google Cloud App Engine
  - name: 'gcr.io/cloud-builders/gcloud'
    args: ['app', 'deploy']

In this example, we have three build steps:

1. Installing dependencies using npm install.
2. Building the application using npm run build.
3. Deploying the application to Google Cloud App Engine using gcloud app deploy.

Feel free to customize these steps according to your application’s requirements.

Building and deploying the application

To build and deploy your JavaScript application to Google Cloud, follow these steps:

1. Open the command line or terminal and navigate to the root directory of your application.

2. Run the following command to trigger the build process:

   gcloud builds submit --config cloudbuild.yaml
   

   This will start the Cloud Build process and execute the steps defined in your cloudbuild.yaml file.

3. Once the build process completes successfully, your application will be deployed to Google Cloud.
4. You can access your deployed application by visiting the provided URL or using the Google Cloud Console.

Conclusion

In this blog post, we learned how to deploy JavaScript applications to Google Cloud using Cloud Build. We covered the steps for setting up a Cloud Build configuration file and deploying the application. By leveraging Cloud Build, you can automate the build and deployment process, making it easier to manage and scale your JavaScript applications on Google Cloud.
