In this article will discuss the journey behind the LeetCode Wrapped and the tech stack used and a few amazing stats we achieved. 🤩

We recently crossed 5200+ users at (leetcodewrapped.info).

Before going to the deep dive, let’s introduce what it is !

🤔1. 𝗔𝗯𝗼𝘂𝘁 𝗟𝗲𝗲𝘁𝗖𝗼𝗱𝗲𝗪𝗿𝗮𝗽𝗽𝗲𝗱:

📊 𝗪𝗵𝗮𝘁 𝗦𝘁𝗮𝘁𝘀 𝗬𝗼𝘂 𝘄𝗶𝗹𝗹 𝗴𝗲𝘁?
𝗖𝗮𝗿𝗱 𝟬:
Total No of Submissions, Active Days, Maximum Streak, Most Active Month, Most Active Day.

𝗖𝗮𝗿𝗱 𝟭:
Live Contest attended, Average Qns Solved in Contest, Maximum Rating, Highest Rank, Lowest Rank, Most Active Month.

And you can switch any year in O(1) time.

Now Let’s discuss some unscripted stories…

2. How we got this Idea:

When Spotify wrapped was trending in November end at the very end of this month, suddenly that day, I thought why not for LeetCode! to show the user's summary of 2023? In terms of Problems solved summary, active day, Live Contest attempt summary, highest rank, lowest rank, etc whatever we can fetch. 🙂

At first, I thought about building one Android Application to do that, and for data scrapping, I already knew about the GraphQL Schema to retrieve all the info we needed. One example below …

// EndPoint: "https://leetcode.com/graphql"
query userProfileCalendar {
        matchedUser(username: "userName") {
            userCalendar (year: 20xx){
                activeYears
                streak
                totalActiveDays
                dccBadges {
                    timestamp
                    badge {
                        name
                        icon
                    }
                }
                submissionCalendar
            }
        }
    }

But then I thought, if I build an Android Application, it will take approx 2/3 days to build and 6/7 days for publishing but I need this immediately, and thought why do people download the Android Application from the Play Store to view these stats only !! 🥲

I thought about other users' perspectives, so there was an option to build a website. But I have a very basic knowledge of web frontend, so at first I avoid that. I know that I can easily manage to build the Backend as well as RestAPI endpoints. But for the front end, I need someone to build that.🤔

As I have very very less friends in my contact (apparently have 16k+ followers on LinkedIn 😂) and specifically need a frontend peep. ya got one friend who can easily do this and we can make it possible to live immediately within 1/2 days as she has prior knowledge about webdev.

watch some beginning stories, how it actually started 🥲🙂

without a single thought, we started working on that (30/11/2023)

I told everything that we wanna build and what type of frontend UI we required. Then, both of us started working, I was in the backend to build the APIs endpoint and she started building the front end. 🚀.

The deadline was: 24 hours 🙂, ya set our deadline within 24 hours to submit our work in front of each other.

and we finished, then after slight modifications, we launched 🥂.

Like, we talked Thursday night and launched on Sunday 😁.

and ya at 6.30 am final website was live and the next day for attendance need to go to the college (few wow-wow moments)

And, ya final website was launched at 6:30 AM and we started sharing the same at the End of the day.

Hehe, how the story started and now reached at 5,300+ users 😁.

3. The tech behind LeetCode wrapped:

We used normal HTML, and CSS to develop the Website and to build the Backend means API endpoint, we used Python Flask and hosted at Cyclic.

And in the website, we used JavaScript to implement the functionality.

That time (because right now we majorly modified LeetCode Wrapped) our API gives these responses by entering the userName.

{
    "average_problems_solved_contest": 2.68,
    "contest_attended": 53,
    "highest_rank": 384,
    "lowest_rank": 7982,
    "max_rating": 2054.983,
    "max_streak": 260,
    "most_active_day": "13,Apr",
    "most_active_month": "May",
    "most_active_month_contest": "Apr",
    "total_active_days": 336,
    "total_questions_solved": 2822
}

Right now, the code behind this is not public. We will soon change the private repo to a public one.

4. Some amazing stats we achieved:

5200+ users crossed 💚
Active users from 15+ countries, including the USA, Canada, Bangladesh, Russia, Kyrgyzstan, etc.
within 30 minutes of launching, we achieved 150+ users.

5. Modifications we did later:

N𝗼𝘄 𝗨𝘀𝗲𝗿𝘀 𝗰𝗮𝗻 𝗦𝗲𝗹𝗲𝗰𝘁 𝗮𝗻𝘆 𝗬𝗲𝗮𝗿, 𝗮𝘀 𝘁𝗵𝗲𝘆 𝘄𝗮𝗻𝘁 — 𝗶𝗻𝗰𝗹𝘂𝗱𝗶𝗻𝗴 𝗢𝘃𝗲𝗿𝗮𝗹𝗹 𝗦𝘁𝗮𝘁𝘀 🚀

Yes, Now the 𝗟𝗲𝗲𝘁𝗖𝗼𝗱𝗲𝗪𝗿𝗮𝗽𝗽𝗲𝗱 is not bounded to only 2023 Summary stats of Your LeetCode Journey… 😲

⚙️ 𝗙𝗲𝘄 𝗠𝗼𝗱𝗶𝗳𝗶𝗰𝗮𝘁𝗶𝗼𝗻𝘀:
- On the stats page now there will be the years, in which you active on LeetCode
- also byDefault the “Overall” option will open, then you can switch to any Year you want
- At the time of switching to years, it will not take any time or loading to show the data, seamlessly you can switch
(as we received lots of requests regarding this, so finally It’s live)

Now, our API endPoints returns:

{
  "2021": {
    "contest_attended": 0,
    "highest_rank": 0,
    "lowest_rank": 0,
    "max_rating": 0,
    "max_streak": 1,
    "most_active_day": "28,Sep",
    "most_active_day_qns": 1,
    "most_active_month": "Sep",
    "most_active_month_contest": 0,
    "most_active_month_contest_number": 0,
    "most_active_month_qns": 1,
    "problems_solved_contest": 0,
    "total_active_days": 1,
    "total_questions_solved": 1
  },
  ...
  ...
  ...
  ...
  "years": [
    2021,
    2022,
    2023,
    2024
  ]
}

Hope every point crystal clear. So, why are you guys waiting, let’s check out the website and feel free to share your views. We are expecting your feedback. Whatever you feel, just share it with us so that we can improve… 💬
