🏆 Telegram Contest for JavaScript Developers, Round 1

Prize fund: $30,000
Deadline: 23:59 on February 21 (Dubai time)
Who can participate: Everyone
Results: March 2025

Telegram is hosting a contest for JavaScript developers to implement a new feature in Telegram Web A and enhance the existing part of the app.

THE TASK

1. Rework the existing text editor from scratch and eliminate its imperfections:
– Ensure proper support for edit history (Ctrl+Z / Cmd+Z doesn’t work as intended as of now).
– Add support for editing quotes.
– Add support for Markdown syntax.
– Currently, RegExp is used for parsing Markdown, which sometimes causes glitches. Implement an AST-based approach to support all Telegram formatting entities more reliably.

2. Introduce the new Chat Folders appearance based on the provided mockups.
___

Contest Requirements:
– No third-party frameworks and libraries are allowed.
– The changes you introduce must not affect the app’s performance or stability.
– The submission must be consistent with the existing Web A codebase.
– Your implementation must work flawlessly on mobile and desktop Chrome (across Linux, macOS, Windows) and Safari on iOS and macOS.

❗Your app must precisely follow the provided design mockups.

Bonus Task:
Add support for animated chat backgrounds as in other Telegram apps. For reference, check Telegram Web K or this.

Submissions:
Contestants will be able to submit their entries to @ContestBot at a later date. We will further clarify the submission instructions closer to the deadline.

P.S. Winners may be offered a chance to explore further opportunities with Telegram.

🏆 Telegram iOS Contest 2024: Results

We appreciate your patience as we evaluated the results of this contest. The complex task and the initial requirements we outlined proved to be challenging to the majority of contestants.

Out of a total of 23 entries, 7 were disqualified for introducing changes that broke the application build process.

After confirming that the remaining apps could be built and included the features outlined in the contest task, we proceeded to the testing stage.

After many hours of testing and cross-checking the submissions, we discovered that only 4 out of the remaining 16 apps were able to play the HLS streams. Unfortunately, the approach used in these apps is far from optimal and, as a result, cannot be used.

Since we were also working on the same task under the release cycle with an even tighter deadline, here’s the approach currently used in the iOS app:
We use bridging to connect the JavaScript implementation of HLS and the native code. For rendering, we created a player compatible with Media Source Extensions.


After evaluation, we have decided to split the prize fund in half and increase the total prize pool for Round 2 by an additional $25,000. Stay tuned for updates in Q1 2025.

Meet the winners!

2nd PLACE – $6,500
🥈Classy Whale
🥈Bold Wasp

3rd PLACE – $3,000
🥉 Tall Penguin
🥉 Subtle Cow

We have also decided to award 12 other contestants a bonus of $500 for their contributions, and we hope to see them in the prize-winning spots next time. (More details and check if you are on the list – on contest.com)

🏆 Telegram Contest for JavaScript Developers, Round 2

Prize fund: $30,000
Deadline: 23:59 on July 28th (Dubai time)
Who can participate: Everyone is welcome to participate, even if they didn't take part in the previous round
Results: August 18th, 2024

Telegram is hosting a contest for JavaScript developers to implement two new features into Telegram Web and address the scrolling issue on Chrome for Android.

The Task:

1. Implement Media Editor and Multiple Accounts into Telegram Web K based on the provided mockups.
2. Web K is currently experiencing scrolling issues when used on Chrome for Android. This issue causes noticeable lagging on devices with 120 FPS displays, particularly when scrolling through any entities containing numerous media elements – essentially, any channel with larger message bubbles and multiple media items. (You must investigate the issue, provide a detailed explanation of it, and implement a fix that will address the issue.)

Evaluation Criteria and Requirements:

General
– No third-party UI frameworks are allowed.
– The submission must be consistent with the existing Web K codebase.
– Your implementation must work flawlessly on desktop Chrome (across Linux, macOS, Windows) and Safari on macOS. Proper support for other browsers and mobile environments (Android, iOS) will be considered a bonus.

❗️Your app must precisely follow the provided design mockups. Entries that fail to do so will be severely penalized.

Further Clarifications:

Media Editor
– You must not use any libraries or components (i.e., from other existing media editors) for any parts of the Media Editor. All the features presented in the mockups must be built from scratch.
– It is acceptable to send static media when an animated sticker is added to a photo, though a proper conversion into a GIF would be considered a bonus.

Multiple Accounts
The app must properly handle the databases from several accounts, support simultaneous notifications, and oversee all possible edge cases, including forced logout from another device. For reference, you may check official Telegram apps.

Submissions:
Contestants will be able to submit their entries to @ContestBot at a later date. We will further clarify the submission instructions closer to the deadline.

P.S. Winners may be offered a chance to explore further opportunities with Telegram.
21.02.202518:24
@ContestBot is now ready to accept submissions for the JavaScript Contest, Round 1.

New deadline: 23:59 on February 22nd (Dubai time)

We are extending the deadline to give all contestants enough time to properly prepare their submissions. Please prepare your submission at least 2–3 hours before the deadline and avoid uploading until the last moment, as late submissions will not be accepted.

Build the application, then prepare:

-> dist - folder with the build.
-> src - folder with the app's source code.
-> contest.md – a text file that briefly describes the approach used for each task.

- A link to the commit on a public GitHub repository, forked from the Telegram Web A repository.

Your repository may stay private until the deadline.

It seems that many contestants misunderstood the task. We are happy to provide clarifications regarding the task requirements, which you will find below.

Q: Can AVFoundation / VideoToolbox / CoreVideo be used?
A: Yes, anything that doesn't use AVPlayer to handle HLS playback is allowed.

Q: Are third party libraries/frameworks allowed (e.g. ffmpeg)?
A: Yes, anything that doesn't use AVPlayer to handle HLS playback is allowed.

Q: What do you mean by "switching between available video streams"?
A: The ability to change between different quality levels or versions of the video based on factors like network bandwidth or user selection. The player should be able to automatically switch to the most appropriate stream depending on the network conditions, or allow the user to manually select a stream which they prefer.

Q: Are there any minimum technical requirements for a video player? Which features are prioritized?
A: Video playback must be hardware-accelerated.

Q: Do we need support for offline playback?
A: No.

Q: Is it necessary to replace something specific in the source code of Telegram iOS from AVPlayer to our self-written player or all?
A: You only need to replace the relevant code in HLSVideoContent.swift where the AVPlayer is used for handling HLS streams

Q: Which formats and codecs should be supported with HLS and video decoding?
A: fmp4 / H264 / AAC.

Q: Will there be any guidelines on how switching between available qualities should be implemented on the UI/UX part?
A: The UI is already implemented. Quality switching is handled here.

🏆 Design Competition 2024: Results

This was by far the most thrilling design contest we've ever held! We would like to express our sincerest gratitude and admiration to each and every contestant – both those who took their very first steps in the challenging world of design and the noble design veterans who set aside some time from their projects to contribute to a better Telegram of tomorrow. ✨

You all are amazing, and we thank you a lot for your fantastic designs! 💙

Now, let us shed some light on the judging process in this competition. The Telegram Design Team joined forces with the Telegram Contest Department, and each judge spent dozens of hours watching and sorting through all the submissions. Once the judges completed their solo evaluations and highlighted the most promising discoveries, the whole jury met to watch and discuss together all the submissions that were not instantly discarded. Aside from the initially mentioned core criteria, another important consideration was, "How close is this video to the ones we make for Telegram Blog?" 🏅

Thanks to this multistage checking, verification, and discussions, the members of the jury were unanimous in the prize distribution.


In order to justly apprise all the notable and solid works, we've decided to increase the prize fund by another $24,000, totaling $54,000.

📱 🤝 📱 With this competition, we are also introducing a new Contest Rewards 🤑by giving out your prizes in USD₮ on TON – to ensure smooth and instant payouts.

Without further a do, please meet the winners!

🏆 Telegram Android Contest 2024, Round 2: Results

In this Round, the contestants were invited to upgrade the interface of the existing in-chat camera and enhance it with the features from the Stories.

The judges greatly enjoyed the testing stage, taking thousands of photos, recording countless videos, and making more collages than they ever had before (and likely never would again). We would like to thank everyone for their contribution!

The core criteria we initially applied during evaluation was app performance. Each submission was tested on a high-performance device to ensure that the changes introduced by the contestants did not compromise the app's smoothness. This particular aspect proved to be quite challenging for the majority of contestants.

The rest we evaluated was the amount and quality of the features implemented, as specified in the contest task.

Please meet the winners!

🏆 Telegram Contest for JavaScript Developers, Round 2: Results

We were pleased to see both participants from Round 1 and those who joined the Telegram Contests for the very first time! The Contest Task, which covered multiple areas of the app (implementing a new feature, adding another feature that heavily relies on the existing codebase, and fixing an obscure issue), proved to be particularly challenging for the contestants, with no one completing all three tasks.

Most contestants focused on the Media Editor, so the judges adjusted their evaluation accordingly. After many hours of testing, we are pleased to confirm that Hip Hyena secured 🥇1st PLACE by delivering the best media editor among all the submissions. This time, given the input each contestant contributed, we will reward everyone who implemented at least one contest task, even if their implementation wasn't perfect.

Meet the winners!

⚠️ We’ve noticed that many participants uploaded their videos as files to their contest channels.

This is not the right way – the channel should host your demos sent as VIDEOS. ✔️
