AWS-Node-http-ToDo-API

This is a ToDo app API built with node.js and can be deployed using serverless framework. The serverless framework will store the code in S3 bucket and then it will be transfered to Lambda for execution, then a API gateway and will be attached to the Lambda function and along with that DynamoDB will be provisioned with required table. Everything will be done with appropriate IAM roles and logging will be done by CloudWatch. Serveless framework uses CloudFormation for provision and deployment of the resources.

Usage

Add task -

POST - https://xxxxx.execute-api.us-east-1.amazonaws.com/InsertTask
