The article showcases a serverless NodeJS template that demonstrates the implementation of a basic AWS-based REST API with user registration and JWT authentication. The template utilizes various AWS services such as DynamoDB, Lambdas, WAFv2, and API Gateway. The deployment of the entire infrastructure is fully automated using the serverless framework. The author provides an architecture overview for both single-region and multi-region deployments, highlighting the benefits of high availability and reduced geographic latency. The article also includes REST documentation for the user registration, login, and decoding endpoints. Developers can easily add new lambdas by copying the existing lambda folders and modifying the handler code. The serverless.yml file is used to specify the file to use in each lambda and how it connects to API Gateway. This template offers a scalable and highly-available solution for building REST APIs on AWS.
