Angular Labs

These are the lab exercises to support the Angular Courses. In these labs we will be creating a full-blown warehouse management system. They are designed to simulate a real-world web application so your classroom experience matches more closely with how you will use Angular in the real world.

By the time you're finished, you'll have an honest-to-goodness Node/Express web server that serves RESTful JSON data that your Angular application will consume via Ajax requests with and without Observables in rxjs.

Getting started

1. Setup
2. Lab instructions
3. To run a solution
4. About the warehouse
5. RESTful APIs
6. Instructor notes

Setup

There are only two things needed to run the labs:

1. Any active or current version of Node.
2. The Angular cli (ng)

If you want some installation help including verification steps, go here .

Lab instructions

Each lab's instructions are located in the instructions folder.

To run a solution

Each lab can be run without copying any files. Just open a bash shell, cd to the lab solution folder and type in

npm install
npm start

If you want to use a solution from a prior lab as a starter, either copy the whole folder to a new one or simply begin editing the code in that folder. Just realize that you may need to change the path to the server folder in package.json.

About the warehouse data

We have products, locations, orders, customers, and users. They are stored in collections (aka tables) in a flat file JSON database.

Orders

Have a status:

Status	Meaning
0	Ready to pick, pack, and ship
1	Shipped
2	Has problem(s) that a supervisor should fix

Locations

LocationID is a string with this format: AASHB where ...

• AA- Aisle - 01-99
• S - Slot - A-Z
• H - Shelf - 1-9
• B - Bin - A-Z

For example, 01A1A = Aisle 1, Slot A, Shelf 1, Bin A

Only one product will be stored in a location so locationID is a primary key

RESTful APIs

Orders

• GET /api/orders/readyToShip - Get a list of orders that are ready to ship (status=0 means "ready to ship". status=1 means "shipped")
• GET /api/orders/ - Get a list of all orders
• GET /api/orders/:id - Get a single order
• PATCH /api/orders/:id/markAsShipped - Mark the order as "shipped" (status=1)
• PATCH /api/orders/:id/markAsProblem - Mark the order as "has a problem" (status=2)
• POST /api/orders/ - Create a new order. New order record is in the body.
• PUT /api/orders/:id - Replace the order with what is in the body.
• DELETE /api/orders/:id - Delete the order
• PATCH /api/orders/:id - Update the order with the values in the body.

Products

• GET /api/products - All products
• GET /api/products/:id - A single product with that id (ids are between 1 and about 77 currently)
• GET /api/products/featured - All featured products (Those we want to promote. Have featured==true)
• GET /api/products?search=:searchString - All products with searchString as part of the name.
• PUT /api/products - Insert a new product into the database. The product's fields are in the body.
• PATCH /api/products/:id - Update the product. Updated fields are in the body.
• DELETE /api/products/:id - Delete the product

Customers

• POST /api/customers - Create a new customer
• GET /api/customers/:id - A single customer. (ids are between 1 and 78)
• PUT /api/customers/:id - Replace a single customer
• PATCH /api/customers/:id - Update a single customer
• DELETE /api/customers/:id - Delete a single customer

Categories

• GET /api/categories - All categories
• GET /api/categories/:id - Read one category

Locations

• GET /api/locations - All locations
• POST /api/locations - Creaes a new location
• GET /api/locations/:id - Read location for locationID id
• PUT /api/locations/:id - Replace location at locationID id
• PATCH /api/locations/:id - Update location at locationID id
• DELETE /api/locations/:id - Delete location ID id
• GET /api/locations/forProduct/:id - Get all locations where product id can be found.

Users

• GET /api/users - All users
• POST /api/users - Creaes a new user
• GET /api/users/:id - Read user for userID id
