AWS Lambda API CDK Template

Template for creating AWS Lambda APIs using CDK.

Usage

• Clone the template repository from https://github.com/azumbro/AWSLambdaAPICDKTemplate.
• Navigate to the cloned repository and install Node modules by running npm install.
• In lib/lambda_api-stack.js, add the target AWS region and account ID to the ACCOUNT_SETTINGS object.
• In lib/lambda_api-stack.js, add an entry to LAMBDA_FUNCTIONS for each lambda function/API to create as part of the stack.
  • The name field specified the name of the lambda/API.
  • The handler field points to the handler file and function that will serve as the entry point to the lambda/API; these handles should be located in JS files within the resources directory. For example, a value of api1_handler.main would look for an exported main function in the resources/api1_handler.js file.
  • The allowedOrigins field specifies a list of domain origins that can call the lambda/API. An entry of "*" allows for all domains to call the lambda/API.
• Write your lambda/API business logic in the handler functions. A basic example has been provided in api1_handler.main.
• When ready to deploy your lambda/API, run npm run cdk deploy. This will create the relevant CFN stack and lambda functions in your AWS account.
• Get the URL(s) for calling your lambda/API(s). These can be found in the AWS console by navigating the the lambda function list, selection a lambda function, and looking for the value under "Function URL" in the overview panel.
