This is a node application that uses express.js to provide a basic web server that does simple arithematic operations. Logging is done using the winston library and the application is secured using Passport.

There are two logins available. One for admin and one for user. One sample admin and user has already been added.

Admins can login using this endpoint:

/auth/adminLogin

Users can login using this endpoint:

/auth/userLogin

For both the logins, the request type is POST, and the body should contain the fields:

1. email
2. apiKey

The admin credentials are:

username: "[email protected]",
apiKey: "secret"

The user credentials are:

username: "[email protected]",
apiKey: "833b33fca986eebfc320b23f10eaa1de04c36879"

To add a user, login as the admin, using the credentials provided. The application will return a JWT token, which can be used as a Bearer token for additional requests. You can then add a user, using the following POST endpoint:

/users/[email protected]

This will return a randomly generated API key to be given to the user. The user can then use this API key to login using the added username and given API key.

Admins can also fetch all users using this GET endpoint:

/users/getUsers

Users once authenticated can then access the calculator APIs using the JWT token they recieved during login.

The available endpoints are (All are GET requests):

1. /calculate/addtwonumbers?n1=x&n2=y
2. /calculate/subtracttwonumbers?n1=x&n2=y
3. /calculate/multiplytwonumbers?n1=x&n2=y
4. /calculate/dividetwonumbers?n1=x&n2=y

The caclulator microservice runs on port 3030 and can be run by using the command "npm run start".

For running using docker run "docker-compose up --build -d"
