Counting Discord Channels Using Selenium

For my research project, I wanted to get a better sense of how many Discord servers exist, considering there was no official number out there.

So, I searched on Google for a list of Discord servers and found a few websites.

I started out with finding a way to scrape the first website that was listed when I searched for Discord servers’ list:

There wasn’t an official number of Discord servers listed so I investigated how the website looked like. It was fairly simple with buttons “Next” and “Previous” that helped navigate between different pages of Discord servers.

Using Inspect Element, I identified the element associated with the titles of the channels as well as identified the element associated with the “next” button. Then, using Selenium, I constructed a loop which clicked on the next button, waited for 3 seconds, and added all the servers to the list:

# The path works because I have moved the "chromedriver" file in /usr/local/bin
browser = webdriver.Chrome(executable_path='/usr/bin/chromedriver')


a = 0

#Use infinite loop since the total number of pages is unknown. 
#At least in jupyter notebooks, it'll stop when it can't find the "Next" button on the last page)
while True:
    names = browser.find_elements_by_class_name("server-name")
    for name in names:
    moveforward = browser.find_elements_by_xpath("//*[contains(text(), 'Next')]")[0]
    print a

Then, I used the Pandas library to make sure there were no duplicate servers:

#Find Duplicates using Pandas library
cleanList = pd.unique(listofChannels).tolist()

Finally, to tally up all of the servers, I just used Python’s len() function:

count = len(cleanList)
print count

In the end, I counted 13,040 servers listed on the site.
