I used PostgreSQL from my local PC , you can find its url from knex file , just have to change back to yours

After that please run migrations and seed since for authentication I am creating two more coloumns in Customer table , email and password and run the seed file to populate ,the emails are firstname+@gmail.com and passwords are firstname+123 (hashed value , using bcrypt 10 rounds)

1st i have uploaded .env file since it is a private repo , 2nd i have used Raw SQL even though knex ORM is in project because it is was this way in the code given

• npm i //to install new dependencies
• npx knex migrate:latest --env development //to run migrations
• npx knex seed:run --env=development //to run seeds
• then nodemon (node server.js)

to get the token run the Customer Post api , localhost:3000/customer and add email and password in body i.e

{ "email": "liam@gmail.com", "password" : "liam123" }

after getting the token please ut token in postman Header by creating key Authorization and value Bearer [token], I havent tried with postmans built in Authorization Tab but that should work too

the get apis are simple

for post and put

post order

send this body and token in header

{ "customer_id" : 1 , "products" : [ { "product_id" : 8 , "quantity" : 17 }, { "product_id" : 9 , "quantity" : 23 } ] }

for put request send this body and token in header

I havent tested this fully but it works for a dummy backend , sometimes values get bad because of mutation i am using very bad logic , using let keyword etc , I havent thought on it much , but it does work 99% of the time , it can be better i will do later if i get time for now for this task i feel like it is ok

Thank you
