This guide teaches how to create a Serverless API using AWS Lambda, CDK (with TypeScript), and Neon. The API is a REST API with a single HTTP endpoint that returns a list of products from a Neon database. The prerequisites include basic knowledge of JavaScript/TypeScript as well as Node.js, an AWS account, and experience working with AWS. The guide covers the installation of CDK CLI, setting up a new CDK project, defining Lambda function, app stack, creating a Neon Postgres database, storing its connection string in AWS Secrets Manager, deploying the project, and cleaning up afterwards.
