Davide SantangeloHi
just for fun I implemented a very simple algorithm that allow to calculate "Karma" rank of dev.to website, based on actual dev.to v0 API.
This is a simple ruby code ( you must install rest-client gem )
class DevToKarma
API_URL = 'https://dev.to/api'
def initialize(username)
@username = username
end
attr_reader :username
def posts
page = 1
result = []
loop do
response = RestClient.get "#{API_URL}/articles?username=#{username}&page=#{page}"
posts = JSON.parse(response.body)
result << posts
page = page + 1
break if posts.size == 0
end
result.flatten
end
def user
response = RestClient.get "#{API_URL}/users/by_username?url=#{username}"
JSON.parse(response.body)
end
def karma
joined_at_timestamp = Time.parse(user.dig('joined_at')).to_i
posts_count = posts.size
total_comments_count = posts.map { |r| r['comments_count'] }.sum
total_positive_reactions_count = posts.map { |r| r['positive_reactions_count'] }.sum
karma = ( posts_count + total_comments_count + total_positive_reactions_count ).to_f / ( joined_at_timestamp / 1000 / 1000 ) * 100
karma.to_i
end
end
Examples
DevToKarma.new('daviduco').karma # My own karma
=> 23
DevToKarma.new('ben').karma # Ben Halper karma
=> 3529
obviously it is a "stupid" and little mathematical solution. Many other considerations and variables to use are missing. But it's a start!
