Task 3

Task: https://github.com/rolling-scopes-school/aws/blob/main/aws-developer/03_serverless_api/task.md

What was done?

• Created two Lambda functions: getProductsList and getProductsById.
• Integrated these functions with API Gateway.
• Added CORS support.
• Created Swagger documentation.
• Added unit tests for Lambda functions.

Additional scope

• Swagger documentation: added openapi.yaml file.
• Unit tests: created tests for getProductsList and getProductsById.
• Code is separated into different modules for better maintainability.

How to run Swagger locally?

1. Ensure you have the necessary dependencies installed:
   • npm install swagger-ui-express yamljs express --legacy-peer-deps
2. Run the Swagger server:
   • npm run start-swagger

#Evaluation Criteria
[x] 100/100

###Task 3.1

• [x]Lambda function getProductsList created under the same AWS CDK Stack file of Product Service.
• [x]Lambda function is triggered by the HTTP GET method.
• [x]The requested URL is /products.
• [x]The response from the lambda is a full array of products (mock data is used).
• [x]The endpoint is integrated with the Frontend app for PLP (Product List Page) representation.

###Task 3.2

• [x]Lambda function getProductsById created under the same AWS CDK Stack file of Product Service.
• [x]Lambda function is triggered by the HTTP GET method.
• [x]The requested URL is /products/{productId}.
• [x]The response from the lambda is 1 searched product from an array of products (mock data is used).
• [x]Proper error handling for "Product not found" scenario.

###Task 3.3

• [x]Work is committed to a separate branch (e.g., task-3) from the latest master in the repository.
• [x]A pull request to the master branch is created.
• [x]The link to the pull request is submitted to the Crosscheck page in RS App.

###Additional Scope (+30 points)

• [x](+7.5 points) Swagger documentation is created for Product Service.
  The openapi.yaml file is added to the repository.
  Can be rendered by Swagger Editor.
• [x](+7.5 points) Lambda handlers are covered by basic UNIT tests (no infrastructure logic needs to be covered).
  Tests for getProductsList and getProductsById are implemented.
• [x](+7.5 points) Lambda handlers (getProductsList, getProductsById) code is written not in one single module (file) and is separated in the codebase.
  The code is modularized.
• [x](+7.5 points) Main error scenarios are handled by the API.
  Proper error messages are returned for scenarios like "Product not found".
