How can I add "current streak" of contributions from github to my blog?

If you want something that matches the visual appearance of GitHub's chart, check out these projects which use https://github.com/users/<username>/contributions_calendar_data but also apply other factors based on Github's logic.

• https://github.com/akerl/githubchart
• https://github.com/akerl/githubstats

The URL for the plain JSON data was: https://github.com/users/[username]/contributions_calendar_data [Edit: Looks like this URL no longer works)

There is a URL which generates the SVG, which other answers have indicated. That is here: https://github.com/users/[username]/contributions

Simply replace [username] with your github username in the URL and you should be able to see the chart. See other answers for more in-depth explanations

Considering the GitHub API for Users doesn't yet expose that particular information (number of days for current stream of contributions), you might have to:

• scrape it (extract it by reading the user's GitHub page)
  As klamping mentions in his answer (upvoted), the url to scrap would be:
  https://github.com/users/<username>/contributions_calendar_data
https://github.com/users/<username>/contributions
  (for public repos only, though)

  SherlockStd has an updated (May 2017) parsing code below:

  https://github-stats.com/api/user/streak/current/:username
  

• try projects which are using https://github.com/users/<username>/contributions_calendar_data (as listed in Marques Johansson's answer, upvoted)

  • IonicaBizau/git-stats:

• akerl/githubchart (Github contribution SVG generator)
• akerl/githubstats (Github contribution statistics)

• build that graph yourself: see the GitHub project git-cal

git-cal is a simple script to view commits calendar (similar to GitHub contributions calendar) on command line.
Each block in the graph corresponds to a day and is shaded with one of the 5 possible colors, each representing relative number of commits on that day.

• or establish a service that will report, each day, any new commit for that given day to a Google Calendar (using the Google Calendar API through a project like nf/streak).
  You can then read that information and report it in your blog.

You can find various example of scraping that information:

• github_team_calendar.py
• weekend-commits.js

As in:

$.getJSON('https://github.com/users/' + location.pathname.replace(/\//g, '') + '/contributions_calendar_data', weekendWork);

• leaderboard.rb:

Like:

leaderboard = members.map do |u|
  user_stats = get("https://github.com/users/#{u}/contributions_calendar_data")
  total = user_stats.map { |s| s[1] }.reduce(&:+)
  [u, total]
end

• ... (you get the idea)

[Project deprecated and unavalaible for now, will be back online soon.]

Since the URL https://github.com/users/<username>/contributions_calendar_data don't work anymore, you have to parse the SVG from https://github.com/users/<username>/contributions.

Unfortunately, Github loves security and CORS is disabled on their server.

To solve this issue, I've setup an API for me and everyone who needs it, just GET https://github-stats.com/api/user/streak/current/{username} (CORS allowed), and you'll get and answer like:

{
  "success":true,
  "currentStreak": 3
}

https://github-stats.com will soon implement more stats endpoints :)

Please ask for new endpoint at https://github.com/SherloxFR/github-stats.com/issues, it will be a pleasure to find a way to implement them !
