JS代写 | COMP2041 Assignment2

JS代写 | COMP2041 Assignment2


JavaScript is used increasingly to provide a native-like application experience in the web. One major avenue of this has been in the use of Single Page Applications or SPAs. SPAs are generated, rendered, and updated using JavaScript. Because SPAs don’t require a user to navigate away from a page to do anything, they retain a degree of user and application state.
There are millions of websites that utilise SPAs in part of, or all of their web applications.
The assignment intends to teach students to build a simple SPA which can fetch dynamic data from a HTTP/S API. Your task will be to provide an implemention of an SPA that can provide a number of key features.
Some of the skills/concepts this assignment aims to test (and build upon):

  • Simple event handling (buttons)
  • Advanced Mouse Events (Swipe)
  • Fetching data from an API
  • Infinite scroll
  • CSS Animations
  • Web Workers
  • Push Notifications (Polling)
  • Offline Support
  • Routing (URL fragment based routing)


The backend server will be where you’ll be getting your data. Don’t touch the code in the backend; although we’ve provided the source, it’s meant to be a black box. Final testing will be done with our own backend. Use the instructions provided in the backend/ to get it started.
For the full docs on the API, start the backend server and navigate to the root (localhost:5000). You’ll see all the endpoints, descriptions and expected responses.

A Working Product

Your site should be compatible with ‘modern’ Chrome, Safari, and Mozilla browsers. We will assume your browser has JavaScript enabled, and supports ES6 syntax.

Getting Started

Clone the gitlab repository using the instructions below. It has a code, full documentation, and a working server you’ll need for developing your frontend application.
Please read the relevant docs for setup in the folders backend/ and frontend/ of the provided repository. Each folder outlines basic steps to get started. There are also some comments provided in the frontend source code.


Level 0 focuses on the basic user interface and interaction building of the site. There is no need to implement any integration with the backend for this level.


It is a requirement of the assignment that when you work on the assignment for more than a few minutes you push the work to above).
You must implement this assignment in Javascript.
You may use small amounts (< 10 lines) of general purpose code (not specific to the assignment) obtained from a site such as Stack Overflow or other publically available resources. You should attribute clearly the source of this code in a comment with it.
You can not otherwise use code written by another person.
Do not use NPM to install libraries other than as indicated in the specifcation.
You can not, for example, use the popular Javascript framework such as Angular or React.
You are permitted to use CSS from external sources as long as it properly attributed.
For example, you are permitted to use the popular Bootstrap CSS framework.
Some Bootstrap functionality relies on accompanying Javascript. You are permitted to include this Javascript.
The Javascript accompanying Bootstrap requires the popular general purpose Javascrpt library jQuery. You are permitted to include jQuery so bootstrap can use it. However you are not permitted to use jQuery in the code you write for the assignment.
