# Welcome to Authentication API

- built by using Node, express and MongoDB

## Features

- Authentication and Authorization using jwt token

- Session management

- Login

- Register

- Update Profile

- Update Email

- Update Password

- Global Error Handling

- Logging Request and errors

- Extensible code flow and Folder structure

- Best env variable setup

## Code Flow

- First browser sends the request to the server

- Server points to our specific routes

- before the controller, it may be that there will be middlewares or validators or maybe both

- If no Middleware of the validator then the request goes to the specific controller

- Controllers will send back the response, if no need to call services

- Services are basically functions that help us to get data from DB (here is Mongo DB)

- Service may use models to save data in some specific format

Note:

Middleware/validators may or may not be there

Services/models may or may not be there
