}

response

    "id": "654d046d5b494b47d7705481",
    "message": "Login Successfull"
}

Implement token-based authentication using JWT for secure user authentication. Provide a unique token upon successful authentication.
Ensure handling of JWT refresh tokens.

Solution :
- Auth and Refresh , JWT token is used for authentication and authorization
- Auth token used for user authentication and Refresh token is used for keep the cookie up to date

User Roles and Permissions:

Implement role-based access control (RBAC) to assign predefined roles (e.g., user, admin) to users. Note that CRUD operations are not required for this task.

solution:

GET /:id

user can access their profile info using their ID ,

ONLY ADMIN can retrive any users data using ID
- request
- ```
GET localhost:8080/654d046d5b494b47d7705481
```
- response
- ```
{
    "_id": "654d046d5b494b47d7705481",
    "firstname": "sk",
    "lastname": "raka",
    "email": "skshahra@gmail.com",
    "password": "",
    "telephone": "",
    "address": "",
    "accounttype": "admin"
}
```

Another Demo Service:

Create a demo service for authenticated users that allows them to retrieve lists of data arrays.

solution :

GET /alluser

ONLY ADMIN can access this route

request
```
GET  localhost:8080/alluser
```
Response

[
    {

        "email": "skshahra@gmail.com",
        "password": "$2a$10$uGTE6IRREQHT2frMeJEb8eTF9JsdZMMysnzRotlIcZcbHU4dGfYrW",
