Would you like to enable X-Ray tracing on the function(s) in your application?  [y/N]:

Would you like to enable monitoring using CloudWatch Application Insights?
For more info, please view https://docs.aws.amazon.com/AmazonCloudWatch/latest/monitoring/cloudwatch-application-insights.html [y/N]:

Project name [sam-app]:

    -----------------------
    Generating application:
    -----------------------
    Name: sam-app
    Runtime: nodejs18.x
    Architectures: x86_64
    Dependency Manager: npm
    Application Template: hello-world-typescript
    Output Directory: .
    Configuration file: sam-app/samconfig.toml

    Next steps can be found in the README file at sam-app/README.md


Commands you can use next
=========================
[*] Create pipeline: cd sam-app && sam pipeline init --bootstrap
[*] Validate SAM template: cd sam-app && sam validate
[*] Test Function in the Cloud: cd sam-app && sam sync --stack-name {stack-name} --watch

これでsam-appができます。
node.jsのプロジェクトを初期化します。

$ cd sam-app/hello-world
$ npm install

そしてSAM CLIでビルド & デプロイ

$ cd ..
$ sam build
$ sam deploy --guided

Amazon SAMについて勉強中でデプロイしたPython版のHello Worldと中身は一緒ですね。
pythonからnode.js + TypeScriptに変わっただけです。
