Build a Serverless API using AWS Lambda, CDK, and Neon

This guide provides a comprehensive tutorial on building a serverless API using AWS Lambda, AWS Cloud Development Kit (CDK) with TypeScript, and Neon, a serverless Postgres database. It outlines the process of creating a REST API with a single HTTP endpoint that retrieves a list of products from a Neon database, emphasizing the need for basic knowledge in JavaScript/TypeScript, Node.js, and AWS. The guide details the use of various technologies, including AWS Lambda for scalable, serverless code execution, and AWS CDK for defining cloud infrastructure as code. It explains how to set up a development environment, create and deploy a CDK project, define a Lambda function, and securely manage database credentials with AWS Secrets Manager. Furthermore, it covers the deployment of the API, retrieval of database connection details, and provides instructions for cleaning up resources to prevent incurring unexpected AWS charges. The guide concludes with links to additional resources and articles for further exploration.
