How to Deploy NestJS to AWS Lambda Using CDK and GitHub Actions

to run npx cdk bootstrap once per AWS account and region. If you're working in a different region or want to use another IAM identity, you can specify the environment using:

shell
 
1npx cdk bootstrap aws://<account-id>/<region>

This command sets up the necessary resources for CDK deployments in that specific environment.

Defining Infrastructure with AWS CDK

Now that your AWS account is bootstrapped and your credentials are configured, you can define your infrastructure using AWS CDK. We'll create a stack that provisions an API Gateway backed by our Lambda function.

1. Install Required Packages

First, install the necessary packages for defining serverless applications in CDK:

shell
 
1npm install --save-dev @aws-cdk/aws-apigateway @aws-cdk/aws-lambda-nodejs @aws-cdk/aws-iam

This installs the AWS CDK constructs for API Gateway and Lambda.

2. Define Your Stack

Open lib/infra-stack.ts (or similar) in your editor, and replace its contents with the following code:

typescript
 
1import * as cdk from 'aws-cdk-lib';
2import { Construct } from 'constructs
