Install the dependencies using npm i.
Launch server using npm start and go to http://localhost:8080/
This exercise involves implementing various aspects of a hotel booking system. It involves a variety of operations on the database to fetch, insert and update data.
The tasks build on your previous experience using SQL with SQLite and Node.js. The key components of the application are as follows:
index.js- sets up the application for useserver/api.js- routes and application logic for the APIpublic/*- each folder contains the front-end code that interacts with the API for each exercise belowdatabase/database.sqlite- SQLite database containing some seed data
Below is the database schema that will be used for the exercise.
In order to complete the exercises below, you will need to edit the code in /server/api.js, generally guided by the TODO comments.
Go to http://localhost:8080/ to get started.
Before getting started, we need to complete the database schema. The database provided contains 4 tables - you must create the tables reviews and reservations in order to complete it. You should set up these tables as follows:
reservations
id INTEGER PRIMARY KEY AUTOINCREMENT
customer_id INTEGER
room_id INTEGER
check_in_date DATE
check_out_date DATE
room_price INTEGER
reviews
id INTEGER PRIMARY KEY AUTOINCREMENT
customer_id INTEGER
room_type_id INTEGER
rating INTEGER
comment TEXT
review_date DATE
You can do this however you choose - through the sqlite command line interfact, or via a GUI such as SQLiteStudio.
User story: As a staff member, I want to be able to view a list of customers
An example has been provided for this exercise, showing how to interact with the SQLite database. Simply uncomment the TODO section, and comment out the existing JSON response being returned.
User story: As a guest, I want to register my details so that I can check availability for my stay
Take the data being POSTed to the /customers endpoint and insert it into the database.
User story: As a guest, I want to browse the types of rooms available at the hotel in ascending price order so I can decide which room I'd like to book
We store prices in pennies as integers rather than as floats as they tend to cause less problems when performing calculations.
Where the current_price does not equal the standard_price, show the standard_price with a line through, and the current_price immediately after (e.g. £80 £70).
User story: As a staff member, I want to be able to apply a discount to the rate of a specific type of room so that it will encourage bookings
You can check this is working correctly by cross-referencing with the interface in exercise 3.
User story: As a guest, I want to book a room so that I have somewhere to stay on my holiday
Bear in mind that the room_price should be set to the current_price of the room_type table.
User story: As a staff member, I want to be able to search for a booking by the customer's reservation ID or name so that I can confirm their stay
User story: As a staff member, I want to be able to see a list of the bookings over the next month in chronological order so that I can prepare the hotel
User story: As a staff member, I want to be able to create an invoice including any surcharges so that I can request payment from guests
User story: As a guest, I want to be able to leave a review so that I can inform others about the quality of the rooms
User story: As hotel manager, I want to display average rating and reviews of each room type so that guests can feel comfortable about the quality of the hotel
- Can you add validation to ensure erroneous data isn't added to the endpoints that insert data into the database?
- Can you add error messages to describe the errors that are encountered?
- Can you add a success message when data has been added/updated successfully?
- Can you ensure each customer added has a unique email address?
- Can you replace the input fields that ask for an ID with a dropdown allowing the user to select one of the existing records?
