-# cdk-lambda-apigateway
-CDK Lambda API Gateway sample project
+# Sample project for API Gateway and Lambda with CDK
+
+To deploy without dependencies and CloudFormation limitation of Template body size(512k), create small API stacks for each Microservice or module.
+
+![apigw](./screenshots/apigw.png?raw=true)
+
+Table of Contents
+
+1. Deploy root-api stack
+2. Deploy device-api stack
+3. Deploy product-api stack
+
+## Prerequisites
+
+```bash
+npm install -g aws-cdk@2.25.0
+
+# install packages in the root folder
+npm install
+cdk bootstrap
+```
+
+Use the `cdk` command-line toolkit to interact with your project:
+
+* `cdk deploy`: deploys your app into an AWS account
+* `cdk synth`: synthesizes an AWS CloudFormation template for your app
+* `cdk diff`: compares your app with the deployed stack
+* `cdk watch`: deployment every time a file change is detected
+
+## CDK Stack
+
+| Stack                         | Time    |
+|-------------------------------|---------|
+| root-api    (24kb)             | 1m 30s  |
+| device-api  (24kb)             | 1m 30s  |
+| product-api (20kb)              | 1m 30s  |
+| Total                         | 4m 30s  |
+
+### Step 1: root-api
+
+Create the Root API and dummy method to import from device-api and product-api.
+
+```bash
+cd root-api
+cdk deploy
+```
+
+[root-api/lib/root-api-stack.ts](./root-api/lib/root-api-stack.ts)
+
+### Step 2: device-api
+
+```bash
+cd ../device-api
+cdk deploy
+```
+
+[device-api/lib/device-api-stack.ts](./device-api/lib/device-api-stack.ts)
+
+SSM parameter:
+
+* /cdk-lambda-apigateway/rest-api-id
+* /cdk-lambda-apigateway/root-resource-id
+
+### Step 3: product-api
+
+```bash
+cd ../product-api
+cdk deploy
+```
+
+[product-api/lib/product-api-stack.ts](./product-api/lib/product-api-stack.ts)
+
+SSM parameter:
+
+* /cdk-lambda-apigateway/rest-api-id
+* /cdk-lambda-apigateway/root-resource-id
+
+### Reference
+
+* Template body size: 512k
+* Template body size in an Amazon S3: 1M
