Background and Description

For this project, you will be building a hotel management tool for hotel customers and staff to manage room bookings and calculate customer bills.

Goals and Objectives

  • Use object and array prototype methods to perform data manipulation
  • Create a clear and accessible user interface
  • Make network requests to retrieve data
  • Implement a robust testing suite using TDD
  • Write DRY, reusable code that follows SRP (Single Responsibility Principle)


Dates and deadlines to be aware of:

Initial Setup

For this project, you will want to use this Webpack Starter Kit repo. Setup instructions are in the README.

You will also need to clone down this local server and have it running in a separate tab in your terminal each time you run your client.


Below are all the endpoints set up for this project. You may not use all of them. Pay attention to the functionality required of each iteration when picking the appropriate endpoint.

Description URL Method Required Properties for Request Sample Successful Response
Get all customers http://localhost:3001/api/v1/customers GET none object with customers property containing an array of all customers
Get single customer http://localhost:3001/api/v1/customers/<id> where<id> will be a number of a customer’s id GET none object of single customer’s info
Get all rooms http://localhost:3001/api/v1/rooms GET none object with rooms property containing an array of all rooms
Get all bookings http://localhost:3001/api/v1/bookings GET none object with bookings property containing an array of all bookings
Add new booking http://localhost:3001/api/v1/bookings POST { "userID": 48, "date": "2019/09/23", "roomNumber": 4 } { message: 'Booking with id <id> successfully posted', newBooking: <Object with trip info just posted> }
Delete single booking http://localhost:3001/api/v1/bookings/<id> where<id> will be a number of a booking’s id DELETE none { message: Booking #<id> has been deleted }


All POST and DELETE requests should have the following headers:

  "Content-Type": "application/json"

Remember, a .catch won’t necessarily run on a bad response (ie 4xx level status) from the server. Make sure you’re checking your response status codes and messages if something isn’t working as expected.



Consider how past projects specified a ‘Data’ section and a ‘User Stories’ section throughout the iterations description. You’ll noticed that you’re only supplied with User Stories below. Analyze each user story to determine what data you’ll need to work with and plan what functions you’ll create to manipulate that data.

Don’t get too caught up with polishing your dashboard too early. You’ll want to focus your energies first on the data and calculation functions, and then move on to the dashboard display. Establish some kind of minimum viable product (MVP) for your dashboard look, and then polish from there

1. Dashboard

As a customer:

  • I should see a dashboard page that shows me:
    • Any room bookings I have made (past or upcoming)
    • The total amount I have spent on rooms

2. Customer Interaction

As a customer:

  • I should be able to select a date for which I’d like to book a room for myself
  • Upon selecting a date, I should be shown a list of room details for only rooms that are available on that date
  • I should be able to filter the list of available rooms by their roomType property
  • I should be able to select a room for booking
  • In the event that no rooms are available for the date/roomType selected, display a message fiercely apologizing to the user and asking them to adjust their room search

Refer to the “Add new booking” section from the endpoints table above!

3. Accessibility

  • You must be able to tab through your app and use it without a mouse
  • Your app must still be usable when tested with a colorblind extension
  • You must score as close to 100% as possible with the Lighthouse and WAVE accessibility audits. Be prepared to explain any accessibility audits your application is failing.
  • Your HTML must be written semantically and should use ARIA attributes for any UI elements that are not understood by the screen reader (ONLY if needed / appropriate)

4. Login

When first arriving at the site, a user should be able to log in with a username and password.

As a customer:

  • I should be able to login
    • I will see a login page when I first visit the site
    • I can log in with the following credentials:
username: customer50 (where 50 is the ID of the user)
password: overlook2021
  • Upon successfully logging in, I should see my dashboard.

Refer to the “Get single user” section from the endpoints table above!

5. Manager Interaction (extension)

Your app should now support two different types of users. In addition to having a customer, you will now add a manager.

As a manager:

  • I should be able to login
    • I will see a login page when I first visit the site
    • I can log in with the following credentials:
username: manager
password: overlook2021

As a manager, upon logging in:

  • I should see a dashboard page that shows me:
    • Total Rooms Available for today’s date
    • Total revenue for today’s date
    • Percentage of rooms occupied for today’s date

As a manager:

  • I should be able to search for any user by name and:
    • View their name, a list of all of their bookings, and the total amount they’ve spent
    • Add a room booking for that user
    • Delete any upcoming room bookings for that user (they cannot delete a booking from the past)

Refer to the endpoints table above for deleting a single booking


You should NOT use the original data files in the data directory for testing. These are big files to begin with, and a real-world dataset would have millions of records. That’s far too big to use every time you want to run a test.

Instead, for your tests, you should create small, sample datasets that match the structure of the application data. By creating this sample dataset, you will also know if your functions are working correctly because you can do the calculations by hand with a much smaller dataset.

You are expected to:

  • Build a robust testing suite. This might include testing pure functions in your scripts.js.

Remember to test all possible outcomes (happy/sad/etc). Ask yourself:

  • Does the function return anything?
  • Are there different possible outcomes to test based on different arguments being passed in?

You are not expected to test:

  • DOM manipulation / DOM manipulating functions (like document.querySelector(...))
  • Fetch calls

Minimum Professionalism Expectations

  • Commits are atomic and frequent, effectively documenting the evolution/progression of the application.
  • A project board is utilized (and updated throughout the project) with Github issues and labels.
  • Student uses branches, PRs and thorough code reviews to add new code to the main branch.
  • The README is formatted well and at a minimum contains:
  • Overview of project and goals
  • Overview of technologies used, challenges, wins, and any other reflections
  • Screenshots/gifs of your app


Does the project demonstrate student understanding of the learning goals & concepts?

Projects will answer that question, being marked as yes, not yet, and wow. Similarly, each section of the rubric (see below) will have yes/not yet/wow markings, helping you understand your progress and growth in specific areas.

The overall project outcome (yes, not yet, wow) is determined by “averaging” each section’s outcome. You can think of a “yes” being worth a 1, a “not yet” being worth a 0, and a “wow” being worth a 2.

For this project, an average of 0.5 is considered a yes - a passing project that demonstrates good student understanding! An average of 1+ is considered a wow. Anything below a 0.5 is considered a not yet - a project that indicates that the concepts have not been fully understood (see note in the section below). Please note that for this project, iterations 1-3 must be completed without bugs.

For the rubric sections below, you will be scored as Wow, Yes or Not Yet depending on whether you have demonstrated competency in that area. Each section lists examples of what types of things we may be looking for as demonstrations of competency. Just as there are many ways to approach code, there are many many ways to demonstrate competency. The following examples are not checklists to complete! There are just some examples.

While M2 rubrics do not have a separate section for WOWs like in M1, there are a few WOW examples noted throughout. In addition to these WOW bullets, you can strive for a WOW by demonstrating not just competency, but excellence and thoroughness across the rubric sections.

Functional Expectations

  • Wow: Application fulfills all requirements as well as Iteration 5.
  • Yes: Application fulfills all requirements of iterations 1-4 without bugs. Note: Must be completed in order to pass
  • Not Yet: Application crashes or has missing functionality or bugs.

UI/UX & Accessibility

  • The application can stand on its own to be used by an instructor without guidance from the developer
  • UI/UX is intuitive and easy to read/use
  • Helpful messaging is displayed to prevent user confusion. For example: If a user searches for a room, but none are available then a message is displayed to indicate that the search worked, nothing is broken, there just aren’t any matching rooms available.
  • The Lighthouse and WAVE audit tools were used to improve accessibility.
  • Users who only use keyboards can still navigate this application
  • Users who use a screen reader can still navigate this application
  • Utilizes ARIA attributes on interactive elements when no other tool allows for accessible content
  • Wow option: design is responsive across small, medium and large breakpoints

Fundamental JavaScript and Style / Fetch Competency Examples

  • Code is divided into logical components each with a clean, single responsibility
  • Array prototype methods are used to iterate instead of for loops
  • Project is organized to separate concerns (Ask yourself - where should my DOM manipulation live?)
  • Variables and functions are consistently and appropriately named
  • Code leverages JavaScript’s truthy/falsey principles
  • Demonstrates efforts towards making functions pure when possible. Note: Purity is not possible for every function in a FE application. Strive for it only when it makes sense.
  • Implements GET and POST Fetch requests
  • When utilizing Fetch, the DOM is updated based on the results of that Fetch
  • Errors are handled and messages are displayed to a user when an error occurs
  • Wow option: Effectively implements one or more closure throughout project.


  • Application has a robust and thorough test suite
  • Testing includes happy and sad paths
  • Test suite is organized - a new developer could easily identify what function is causing a test to fail
  • Rather than using the production data, small sample data is stored in its own file and used for testing.
  • Sample data has been crafted to create the scenarios needed for thorough testing.
  • Tests are DRY (Ask yourself - what tools can I use to limit repetitive code?)
  • There are no failing/pending tests upon submission


Evaluations will be done live with an instructor. You’ll be asked to step through the various parts of your application including accessibility audit, the user interface, running tests and looking at fetch calls and JavaScript code.
