Create endpoint for user-registration

What does this MR do?

1. Installing libraries and setting up the npm environment

Libraries:

• mongodb
• express
• mongoose
• nodemon
• bcrypt
• jsonwebtoken
• cors
• multer
• mongodb-memory-server

2. Connect with 'mongodb-memory-server' initially (Will change it to MongoDB Atlas later)

3. Create endpoints for POST requests - /register, /login, /updateUser, /user/:username

4. Create User.model.js which contains the properties of the schema using mongoose

5. Create Controllers for /register, /login, /updateUser, /user/:username

6. Validate authentication

Starting Project

Start server by npm start in the daily-thought-user-service/server directory

Testing endpoints

a. Register Route [/register]

Valid registration -

Username Exists -

Email Exists -

b. Login Route [/login]

You have to register first, and then log in. You can only log in with your username and password.

Valid Login -

User Not Found (Invalid User) -

Invalid Credentials (Password Does not Match)

c. GetUser Route [/user/:username]

You have to register first, and then can use this route. It is a GET request.

Valid User

Invalid User

d. Update User [/updateuser]

This is a PUT Request. After you register and login, you have to get the 'token' from the login route. You have to paste this token in the Auth>Bearer of the /updateuser.

Then you click send, and you will get the following response:

If you go to the GetUser [/user/:username] route again, you will see the email and profile got updated.

Relevant issues

Please ensure the 'Mongoose' is of version "mongoose": "^6.8.0",, as some methods do not work in the newer version.
