AWS Lambda Function Tutorial

Before working with AWS Lambda functions, we need to install the awscli locally. I follow the official document to install the AWS CLI v2 on my Ubuntu 20.10. Also, we need to install the AWS SAM CLI by following this document

There are two different ways to build and deploy Lambda functions described in the light-aws-lambda. The difference is how the cross-cutting concerns are addressed for the Lambda functions.

  • aws-framework addresses CCC within the Lambda function built with Java 11 and AWS API Gateway JWT Authorizer.
  • aws-proxy addresses CCC in the light-proxy instance so that Lambda function can be built with any language.

Lambda Proxy

In this tutorial, we are going to use the light-proxy to address the cross-cutting concerns. We are going to scaffold a project with four Lambda functions based on the petstore OpenAPI 3.0 specification. Specification The petstore specification openapi.yaml and a config-proxy.json can be found in model-config repository in the networknt GitHub organization. This folder also contains a README.md with the commmand lines to generate the petstore project. To generate a project with light-proxy, we need to use the last command in the README. Read More »
