⚠️ This script is tested only on mac and linux. It's not tested on windows machines

✅ Your login credentials are saved on your local machine. They don't leave it at all. They are only sent to CMS platform. You can make sure by reviewing the code

Motivation

Every developer has the coding superpower 😎. So, as a developer, you should automate all the boring stuff 😪 to free up some threads in your mind for the serious work. 👀🤓

Script Description

This script is created to automate downloading the content from the GUC-CMS platform. It fetches the courses you are subscribed in, creates a folder for each course, downloads the content (ALL the content), each file in its corresponding week folder. Et voila! Everything is downloaded 🔥🔥

skip chromium installation

export CHROMIUM_EXECUTABLE_PATH=$(which chromium)
export PUPPETEER_SKIP_CHROMIUM_DOWNLOAD=true

When PUPPETEER_SKIP_CHROMIUM_DOWNLOAD is set to true, puppeteer skips downloading the binaries for chromium, however you must provide an executable path to a chromium binary (which is done via the CHROMIUM_EXECUTABLE_PATH environment variable).

Prepare your machine (if windows machine)

  1. Download Node.js the LTS version then install it. The usual install just next next...

  2. Download Git Bash the windows version and also the usual install. Just tick the option of creating a desktop icon

  3. You should be ready to move to the next step (How to run)

How to run

  1. Clone the repo

    git clone https://github.com/AhmedAshrafAZ/cms-downloader.git

  2. Navigate to the script directory

    cd cms-downloader

  3. Install node modules

    npm install

  4. Add your username (without @student.guc.edu.eg) to the ".env" file

    echo "GUC_SK_USERNAME=your_username" > .env

  5. Add your password to the ".env" file

    echo "GUC_SK_PASSWORD=your_password" >> .env

  6. Run the script and let the magic begin 🎩🎩🔥🔥

    npm start

Unrevealing the magic behind the script 🤓

This script is mainly based on web scraping 🕷🕸 and DOM manipulation.

  • Get the login credintials form the '.env' file and test authentication
  • Fetch the home page to get all the courses that the student is subscribed in.
  • Navigate to each course
  • Select (using querySelector) all the anchor tags that contains download attribute
  • Rename the value of the download attribute to the name its card
  • Select all the unrated courses (this is my flag for the non-downloaded content)
  • Download the unrated courses after checking that the week folder and course folder do exist
  • Rate each content after downloading it.
  • And repeat until everything is DONE 🔥🎩💪🏻
