CMPUT 401: Assignment

Winter 2025

The goal of this assignment is to get you acquainted with the technical aspects of the web app development process. In this assignment, you will build a simple REST API and deploy it to a Cybera Rapid Access Cloud instance. This assignment will also get you acquainted with GitHub basics. You are free to choose any programming language, and use any frameworks, packages, modules, libraries, and any database management system.

GitHub

• GitHub Classroom assignment invitation link:https://classroom.github.com/a/j92ybbve

•    Click the link above to create a repository that you will use for this assignment.

•    You will create an issue titled “News API” .

•    You must work off a branch and merge your branch into the “main” branch with a pull request.

•    You must merge the pull request you created into your “main” branch with a phrase that closes the issue you created. DO NOT delete the first branch after merging the pull request and closing the issue.

•    This GitHub repository shouldn’t have anymore commits after the deadline of the assignment.

•    Naming conventions are an important point specially when working in teams, make sure to choose and follow a specific convention for your commit messages, branch names, and other names. Usually in different companies, the convention is already defined or when working in teams a specific convention is agreed upon. For your personal use make sure to check out different conventions before choosing one. Using a unified convention makes your GitHub page look more professional.

Endpoints

Get the current top headlines for Canada

•    For this assignment we are going to use thiswebsiteto get updated news.

•    Please Sign up to the website, you will get a free API key right away.

•    Please don’t input the data manually, your code should do that for you!

•    Store the first 20 news articles for Canada on Jan 1st  2025.

•    Update: You can use this link as there were some questions about other formats.

•    Although the sample response has the following fields, do not save them all (delete url and

urltoimage). When added to the dataset each one of the articles should be assigned a unique ID (this is different from the source id field just leave that as it is) that will be used in other API

calls. Do not save url and urlToImage.

Successful Response structure:

{ "status": 200, "message": "News Updated" }

Modify News http://[ipv6 address]/news/{id} (PATCH) Sample request structure (any fields of the PUT method can be supplied):

{ "author": "bringatrailer" }

{

"status": 200,

"message": "News Modified" }

Delete News

http://[ipv6 address]/status/{id} (DELETE)

Successful Response structure:

{

"status": 200,

"message": "News Deleted" }

If you delete a few of the articles it is fine and you do not need to get them again, you can do that api call once and store the top 20 and delete some of it for test.

API Documentation

•    Use your framework/library of choice to auto-generate API documentation using the OpenAPI standard.

•    The API documentation must be available at http://[ipv6 address]/docs.

•    The API documentation must be valid OpenAPI Spec.

Deployment

•    The system must be deployed on your personal Cybera RAC instance (not the instance you have for your group project).

•    Many web frameworks include some kind of development server that you can use to run your app

during development quickly. For example, in Django, you can easily run your app using python manage.pyrunserver

•    Do NOT use a development server for deployment (e.g., if you useDjango REST Framework,   you can not run it on your server using the command above). This way is great for development purposes, but it is a horrible idea to do it in production for several reasons:

1.   It is not secure

2.   It cannot handle multiple requests well (i.e., it's VERY slow)

3.   You would need to manually restart your server if something happens (your operating system can't take care of this)

•    You need to deploy your API. There are many ways to do it, and it depends on the framework you choose. Use a web server like Nginx, or Apache. You should find a tutorial for your

framework.

• Your server must be listening on port 8080.

Deliverables

We are using GitHub Classroom for this assignment. You must have your code in the GitHub repository associated with the assignment.

Mandatory Files

In addition to your code, you must create four files (pay attention to file text-case and spelling) in your root directory.

1. cybera.txt, containing the IPv6 address of your personal Cybera instance with the deployed API. NOTE THAT THERE IS NO HTTP(S), it is purely the IPV6 address. Don’t include anything else in this file.

Example of the text file contents:

2001:0db8:85a3:0000:0000:8a2e:0370:7334

2. README.md, containing brief information about the framework, programming language, and DBMS that you used, each on a separate line (there should be 3 lines, don’t include

anything else in this file):

Framework Language    DBMS

Example of README.md:

Rocket Rust

MongoDB

3. LICENSE, containing an appropriate license for your code. Refer to these instructions:

https://help.github.com/articles/adding-a-license-to-a-repository/

4. REFERENCES.md which contains links and text of the resources you used to build your project. The format should be a “*” for each reference point.

Example of REFERENCES.md:

* https://stackoverflow.com

* I prompted ChatGPT to ask “how do I open a GitHub issue”
