Sample API: taskly.raunak.com/api

Technical Stack:

• AWS Lambda
• API Gateway
• DynamoDB
• S3 Bucket
• SQS Queue
• Cognito for authentication
• SNS

Implementation

Endpoints

• Get all tasks: GET http://taskly.raunak.com/api/tasks
• Get a task: GET http://taskly.raunak.com/api/tasks/
• Create a task: POST http://taskly.raunak.com/api/tasks/
  • Sample playload:

        {
            "name": "Call mom",
            "description": "reminder to pickup",
            "files": null,
            "dueDate": "12/09/2024"
        }

• Delete a task: DELETE http://taskly.raunak.com/api/

Impelemantation Strategy:

• First create an initial lambda function and return a dummy data
• Create DYNAMO DB and add data
• Update lambda function to connect to DynamoDB and return the data
• Update the lambda function to CRUD data in DynamoDB
• Create API gateway and configure lambda function
• Configure lambda function to implement uploading to s3 bucket
• Impelemnt SQS and SNS to send notification to user
