Create a Serverless JSON Page Using Lambda

AWS Lambda is a serverless compute service, and it doesn't directly serve JSON pages like a traditional web server. However, you can create an AWS Lambda function to handle HTTP requests using an API Gateway, and the Lambda function can generate JSON content as a response.

Below is a simplified example of how you can create a basic AWS Lambda function that generates JSON content in response to an HTTP request:

1. Create Lambda Function:

• Go to the AWS Lambda console.

• Click on "Create function" and choose "Author from scratch."

• Give your function a name, choose a runtime (e.g., python 3.7), and create the function.

2. Write Lambda Function Code:

In the Lambda function code editor, you can write Python code to generate JSON. Here's a basic example:

import json

def lambda_handler(event, context):
    # TODO implement
    return {
        'statusCode': 200,
        'body': json.dumps('Hello from BuildDevOps!')
    }

This example returns a simple JSON page with the message "Hello from BuildDevOps!"

3. Configure API Gateway:

• Go to the API Gateway console.

• Create a new API.

• Set a Security to Open (Not Recommended In Prod Environment)

• Set the integration type to Lambda Function and choose your Lambda function.

4. Access JSON API via URL:

Once deployed, you will get an Invoke URL. Accessing this URL will trigger your Lambda function, and the HTML content will be returned.
