AWS API Gateway CRUD REST API using AWS Lambda, Node.js with AWS-SDK V3

Serverless Notes App Api by Meetkumar Patel

#About this project -It has 5 APIs: createNote, getNote, updateNote, deleteNote, getAllNotes -As it is severless configured with AWS Cloud - it will create same API Gateway endpoints with respected HTTP requests -When the ci/cd pipeline completes deployment, it will create Lamda functions in AWS Lamda (AWS Mgt consol) -I used AWS CloudWatch to see logs(bug fixing) -The project deals with AWS Dynamodb for storing REST API's reponse. So, it will instanciated when db.js files runs and will create an object called "client" from "DynamoDBClient" w/ AWS-SDK -It will create a table and store data. when CRUD operations will be performed it will be managed automatically using DynamnoDB Commands. (Since the project is serverless, there is no need to congfigure server for managing database) -The project is automated using ci/cd pipeline w/ GitHub Actions, when the code will be pushed/commited to 'master/ branch, it will start its deployment automatically. -In backend the serverless framework runs, AWS CloudFormation, AWS Lamda, .yml file, .js files, .json file, etc. will be packaged in .zip file and completes further deployment process
