AWS Cloud API is designed as a lightweight, scalable backend for cloud-native applications.

It leverages AWS managed services to provide secure, highly available APIs while minimizing infrastructure management. The application uses AWS SAM for deployment automation and Infrastructure as Code, making it easy to develop, test, and deploy serverless workloads.

• REST API with API Gateway
• AWS Lambda Functions
• Amazon DynamoDB Integration
• Infrastructure as Code with AWS SAM
• Local Development Support
• Docker-based Build Environment
• TypeScript Support
• CloudFormation Deployment
• Unit Testing
• Cloud Native Architecture

Install the following before running the project:

• Node.js
• AWS CLI
• AWS SAM CLI
• Docker

Clone the repository

git clone https://github.com/iglicoding/aws-cloud-api.git

cd aws-cloud-api

Install dependencies

npm install

Build the application

sam build

Invoke Lambda locally

sam local invoke putItemFunction --event events/event-post-item.json

sam local invoke getAllItemsFunction --event events/event-get-all-items.json

Run the local API

sam local start-api

The API will be available at

http://localhost:3000

Deploy using AWS SAM

sam deploy --guided

During deployment configure:

• Stack Name
• AWS Region
• IAM Permissions
• CloudFormation Capabilities

Once deployed, AWS CloudFormation will output the API Gateway endpoint.

Install dependencies

npm install

Run unit tests

npm run test

• AWS Lambda
• API Gateway
• DynamoDB
• AWS SAM
• CloudFormation

• Node.js
• TypeScript

• Docker
• Jest
• ESLint

Useful documentation:

• AWS Lambda Documentation
• AWS SAM Documentation
• Amazon API Gateway Documentation
• DynamoDB Documentation
• CloudFormation Documentation
