How to run the app

Root url for api: http://localhost:3000

• Clone the repo in local environment and make .env file (optional, no need for this, database deployed on mongod )
• run npm install
• run local mongod server command--mongod
• No need to run mongo server locally, I have deployed it on mongod ATLAS cluster. Now, just run nodemon app.js
• run nodemon app.js or node app.js

Please let me know if you have any problem with connecting to database and any error or bug.

Main Functions

A) For Admin:

1. Add account (Basic JWT token issue and authorization, Assuming it to be registering account of webadmin --admin:bool(true|false))

2. Add products (adding product with passing only after register and login)

3. View Orders ( login required, --it is linked to users and seller id. basic struture is like you have lot of seller id, products and users. It is intersection of particular seller id, all user id's that have order from that seller and products id's. )

B) For End Customers

1. Add account (Assuming it to be register account of user)
2. Login (Basic JWT token authorization)
3. Browse Products (login not required, all the available products in the database or added by all webadmins)
4. Order products (login required, no payment integration, storing seller id and product id)
5. View Orders (login required, view all placed orders)

File Strutures

• config --database (mongodb) connection ---database.js

• lib --It will issue jwt token with the help of jsonwebtoken library, validating hash and salt, and authenticating requests ---utils.js

• models --mongodb models, it has three models each for user, admin, product ---user.js

• routes --middleware for handling all api's
  ---index.js ---users_routes.js ---auth_routes.js ---admin_routes.js

• app.js --server connection on given port and main interference for express and mongodb database.

• generateKeyPair.js ---It generate private and public key pair with the help of node.js crypto library and RSA algorithm. RSA algorithm is asymmetric cryptography algorithm. Asymmetric actually means that it works on two different keys i.e. Public Key and Private Key
