This project is an API for a store website.

This API uses various technologies to achieve the required functionality:

• Postgres for the database
• Node/Express for the application logic
• dotenv from npm for managing environment variables
• db-migrate from npm for migrations
• jsonwebtoken from npm for working with JWTs
• jasmine from npm for testing
• ESLint for linting the code.
• Prettier for formatting the code to be consistent.
• TypeScript
• nodemon for automatic reload at development stage
• postgres for data base

1. Create user with password and additional ,data will be stored inside DB.
2. Open new order for users.
3. Add products into your cart.
4. Gather information about users, products and orders for logged in users.
5. Delete your profile.
6. Update your user profile data.
7. Show user dashboard.

1. create main DB:

• run ( CREATE DATABASE shopping; ) to create a data base on your machine called "shopping"
• create a user on postgres by running ( CREATE USER shopping_user WITH PASSWORD 'password123'; )
• run '\c shopping' to connect to our DB.
• run ( GRANT ALL PRIVILEGES ON DATABASE shopping TO shopping_user; ) so we can access and edit on our DB.

2. Create test DB -if you want to perform testing using jasmine- :

• run ( CREATE DATABASE shopping_test; ) to create a data base on your machine called "shopping_test"
• create a user on postgres by running ( CREATE USER shopping_user_test WITH PASSWORD 'password123'; )
• run ( \c shopping_test ) to connect to our DB.
• run ( GRANT ALL PRIVILEGES ON DATABASE shopping_test TO shopping_user_test; ) so we can access and edit on our DB Via our newly created user.

• clone the project
• run 'npm install' , to install all th needed packages
• run 'npm install -g db-migrate' to install db-migrate globally so we can migrate tables to our DB.
• run 'db-migrate up' to create all of our DB tables to interact with our node project.

• to delete all created tables at once, run "db-migrate reset" , don't run "db-migrate down" because it wont delete tables with foreign-key constrains.

• within console, run (npm install) to install all the needed packages

• This project needs Environment variables to be able to run as expected, but because this variables could be a sensitive info so you need to give your values for some of them.

• I will provide the variables names, then you should give them values:

  1. create (.env) file in the root folder of the app

  2. the variables are:

     DATABASE_HOST = POSTGRES_DB = shopping POSTGRES_USER = shopping_user POSTGRES_PASSWORD = pasword123 ENV = dev POSTGRES_test_DB = shopping_test POSTGRES_USER_test = shopping_user_test SALT_NO = <this is the number of hashing cycles for password hashing, you could add any number> BCRYPT_PASS = <this the added salt on user password before hashing, you could add any string but keep it secure and dont change it or you will lose your data in DB> TOKEN_PASS = <this is the password used for creating and verifying user tokens, you can add any string but keep it secure and dont change it>

  3. add the provided variables with your values to them inside (.env) file.

  How to run :

  • within console run (npm run start) this will start a server for you to interact with the API either using postman or any browser.
  • I will state how to use it in details inside REQUIRMENTS.md.

  Scripts to run VIA npm:

  1. (npm run prettier) => for formatting the code.
  2. (npm run lint) => for lint the code, for better syntax.
  3. (npm run start) => to start the API server.
  4. (npm run test) => to test all methods and endpoint using jasmine at development phase.

This DB have four tables, each table with specific purpose, all tables are connected to each other with foreign keys.

1. Users => all the users data
2. product => information about all products
3. orders => all orders created with their associated products
4. orders_products => many to many table that have relations between orders created and their associated users.

1. Users:

   id SERIAL PRIMARY KEY, f_name VARCHAR(50), l_name VARCHAR(50), user_name VARCHAR(50) NOT NULL, password text NOT NULL , age INTEGER

2. product:

   id SERIAL PRIMARY KEY, name VARCHAR(100) NOT NULL, price INTEGER NOT NULL, category VARCHAR (100)

3. orders:

   id SERIAL PRIMARY KEY, status VARCHAR(15) DEFAULT 'open', user_id BIGINT REFERENCES users(id) NOT NULL

4. orders_products:

   id SERIAL PRIMARY KEY, quantity INTEGER NOT NULL, order_id BIGINT NOT NULL REFERENCES orders(id), product_id BIGINT NOT NULL REFERENCES product(id)
