Express Train

Instructions

1. Create an Express app.

   • Make a new directory called expressTrain.
   • Navigate inside the expressTrain folder.
   • Create an app.js file in the terminal using touch.
   • Initialize a Node.js project in the terminal using npm init -y.
   • Open the folder.
   • Install Express and Morgan as dependencies using npm i and require them in the app.js file.
   • Create a server using Express and use Morgan as a logger. Don't forget to use .json().

Create an Express server with the following features:

• Implement a global store that contains product objects in the following format:

[ { name: 'apple', price: 1.5 } ]

Routes:

1. Root Route ("/"):

   • Return everything in the store.

2. Get All Products Route ("/get-all-products"):

   • Return a list of all product names in an array.

3. Get Product by Name Route ("/get-product/:productName"):

   • Return the full object with name and price for the specified product.

4. Create Product Route ("/create-product"):

   • Add a new object to the store and return "Product added".

Stretch Goals:

• Implement additional checks:

  • Check if the product already exists before adding.
  • If the product exists, return an error message in the response indicating that the item already exists.

• Implement a delete route for deleting an item by name:

  • Remove the specified product from the store.
