Download the DynamoDb-Local jar file for your system here. docker run -p 8000:8000 amazon/dynamodb-local

• Extract the jar file to the root of this repository (the parent of this project folder) under the name: dynamodb_local.

Create a .env file at the root of the project and add in your own values for these enviornment variables.

• AWS_ENDPOINT='http://localhost:8000/'
• AWS_REGION='localhost'
• AWS_ACCESS_KEY_ID='fake-access-key'
• AWS_SECRET_ACCESS_KEY='fake-secret-key'

DynamoDB Local

• Open a terminal at the the folder where you extracted the jar file (Setup section).
  • Run: java -Djava.library.path=./DynamoDBLocal_lib -jar DynamoDBLocal.jar -sharedDb to start it on the default port: 8000.
  • Open a browser at: http://localhost:8000/shell to interact with DynamoDB through the interactive shell.

Lambda Functions

• Run npm run seed to seed some test data.
• Run npm start to start the functions locally.

Test by trying to hit an Api endpoint in the Postman. (should add basic auth header)

• POST http://localhost:3000/users/ - open api
• GET http://localhost:3000/users/ - can be accessed with admin credentials
• GET http://localhost:3000/users/{userId} - can be accessed with any user role
• PUT http://localhost:3000/users/{userId} - can be accessed with any user role
• DELETE http://localhost:3000/users/{userId} - can be accessed with any user role

• I have used jest as an automated testing framework
• eslint is integrated for consistent coding style
• Basic Auth is implemented for fast/easy development but that's not the best choice. We can use json web token for production applications.
• Right now, raw password is stored in dynamodb. This should be encrypted for production use.
