Internet retail, also known as e-commerce, plays a significant role within the electronics industry, as it empowers businesses and consumers alike to conveniently engage in online buying and selling of electronic products. In the latest available data from 2021, the industry in the United States alone was estimated to have generated the substantial amount of US$2.54 trillion, according to the United Nations Conference on Trade and Development. E-commerce platforms like Shopify and WooCommerce provide a suite of services to businesses of all sizes. Due to the prevalence of these platforms, developers should understand the fundamental architecture of e-commerce sites.

The task is to build the back end for an e-commerce site by modifying starter code.

AS A manager at an internet retail company
I WANT a back end for my e-commerce website that uses the latest technologies
SO THAT my company can compete with other e-commerce companies

• must show all of the technical acceptance criteria being met.

  • WHEN I add my database name, MySQL username, and MySQL password to an environment variable file, THEN I am able to connect to a database using Sequelize
  • WHEN I enter schema and seed commands, THEN a development database is created and is seeded with test data
  • WHEN I enter the command to invoke the application, THEN my server is started and the Sequelize models are synced to the MySQL database
  • WHEN I open API GET routes in Insomnia Core for categories, products, or tags, THEN the data for each of these routes is displayed in a formatted JSON
  • WHEN I test API POST, PUT, and DELETE routes in Insomnia Core, THEN I am able to successfully create, update, and delete data in my database

• must demonstrate how to create the schema from the MySQL shell.

• must demonstrate how to seed the database from the command line.

• must demonstrate how to start the application’s server.

• must demonstrate GET routes for all categories, all products, and all tags being tested in Insomnia Core.

• must demonstrate GET routes for a single category, a single product, and a single tag being tested in Insomnia Core.

• video must demonstrate POST, PUT, and DELETE routes for categories, products, and tags being tested in Insomnia Core.

Your database should contain the following four models, including the requirements listed for each model:

• Category

  • id

    • Integer.

    • Doesn't allow null values.

    • Set as primary key.

    • Uses auto increment.

  • category_name

    • String.

    • Doesn't allow null values.

• Product

  • id

    • Integer.

    • Doesn't allow null values.

    • Set as primary key.

    • Uses auto increment.

  • product_name

    • String.

    • Doesn't allow null values.

  • price

    • Decimal.

    • Doesn't allow null values.

    • Validates that the value is a decimal.

  • stock

    • Integer.

    • Doesn't allow null values.

    • Set a default value of 10.

    • Validates that the value is numeric.

  • category_id

    • Integer.

    • References the Category model's id.

• Tag

  • id

    • Integer.

    • Doesn't allow null values.

    • Set as primary key.

    • Uses auto increment.

  • tag_name

    • String.

• ProductTag

  • id

    • Integer.

    • Doesn't allow null values.

    • Set as primary key.

    • Uses auto increment.

  • product_id

    • Integer.

    • References the Product model's id.

  • tag_id

    • Integer.

    • References the Tag model's id.

need to execute association methods on your Sequelize models to create the following relationships between them:

• Product belongs to Category, and Category has many Product models, as a category can have multiple products but a product can only belong to one category.

• Product belongs to many Tag models, and Tag belongs to many Product models. Allow products to have multiple tags and tags to have many products by using the ProductTag through model.

Fill out the unfinished routes in product-routes.js, tag-routes.js, and category-routes.js to perform create, read, update, and delete operations using your Sequelize models.

Note that the functionality for creating the many-to-many relationship for products has already been completed for you.

After creating the models and routes, run npm run seed to seed data to your database so that you can test your routes.

Create the code needed in server.js to sync the Sequelize models to the MySQL database on server start.
