General Info

Here we are building a backend using express and creating a database with mysql for an ecommerce app.

We use the schema.sql file in the db folder to create your database with MySQL shell commands. We use environment variables to store sensitive data like your MySQL username, password, and database name.

our 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.

We 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.

How to Use

In the video below shows how to run th app from the terminal.

*navigate to the root folder of the app then run npmi to istall dependencies *enter mysql -u root -p to start up mysql *enter source schema.sql to create the database *enter quit to exit mysql *run npm run seed to seed the database *run npm start to run the app

We can then check our api routes using Postman
