? 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.

? Unlimited Live Streams

Introducing Live Streams on WebK, featuring the first-ever implementation on Telegram Web. Thanks to Fit Whale's efforts, who worked on them during our recent contest, these Live Streams are now available to all our users.

After the initial contest, we've spent dozens of hours on polishing and further refining the app to deliver the best possible live streaming experience in a web browser.

We are proud to announce that, after significant adjustments and improvements, we now offer a seamless experience on desktop Chrome and Safari, ensuring stable playback even in unstable network conditions.

WebK supports both joining and hosting live streams, which includes managing stream data (with the option to record live stream).

That's all for today and there is even more on the way. Stay tuned!

That's all for today, but there's even more on the horizon. See you in 2024!

We have been working hard to bring you several long-awaited features today – WebK is catching up to the mobile and desktop apps, and will support dozens more features by the end of 2023.

Group and channel admins can now fully manage their communities on the web – with admin lists, permissions and restrictions, invite links and many more. Recent actions and statistics are coming soon, stay tuned!

❤️ Infinite Reactions
The reaction panel has been completely redesigned to hold all your emoji packs – like the thousands of custom emoji available with Premium.

? Mini Apps
Mini Apps have been around for over a year, and recently received several improvements. Mini Apps can host any kind of service – try ordering some (fictional) food with a sample Mini App.

That's all for today, we'll be back with the next update before you know it. ?

P.S. We also smashed dozens of bugs and glitches for an even smoother WebK experience.

Previously on WebK: 8 preset themes were added, bringing beautiful color combinations to customize your app's appearance.

Today's update adds new features to increase your productivity, performance and more.

? Shareable Folders
Your chat folders can now be shared with friends or colleagues – adding the folder and joining all its chats in one tap.

You can create multiple invite links for your folders to give different people access to different chats.

? Powerful Bots
Telegram bots can completely replace any website. These bots can now be launched in any chat – try typing @DurgerKingBot (followed by a space) in any chat.

⚡️ Power Saving Mode
You can extend battery life and improve performance by turning on Power Saving Mode or individually disabling autoplay, animations or effects in Settings > General > Power Saving Mode.

? and More
The app now shows admin titles in chats as well as read time in small groups, and user profiles display which groups you have in common.

Right-clicking a user's profile picture in group chats lets you mention them or open a chat with them.

Telegram Premium can now be gifted to users via their profile – and voice messages support Premium's Voice-to-Text conversion.

Lastly, media received a few improvements – download multiple files simultaneously, use timestamps like 0:15 for audio and video, or pinch to zoom in on media directly from the chat.

? While the devs work on bringing more features to life, WebK now allows you to quickly change your app's color scheme.

In Settings > General you can select between 9 beautiful themes, each with their own day and night versions.

The app will remember your choice between day and night modes, and now has a setting to follow your system theme.

? Happy New Year to everyone! WebK launched its first update of 2023, adding a pack of feaures you can now enjoy on Web!

? Topics 2.0
Admins of any group can enable Topics, creating separate spaces within the group to discuss different subjects – with a sleek two-column layout to easily navigate chats.

?‍?️ Hidden Media
Media hidden with a shimmering spoiler effect is properly displayed in the app – just tap or click to view the image. The next WebK update will allow you to send media with this spoiler effect.

?‍☠️ No-SIM Signup and Login
Users who have an anonymous number from Fragment can login to their existing account or create a new accountwith the number.

? Collectible Usernames
Owners of collectible usernames can now assign collectiblesto their personal account, groups or channels – and manage them within the app.

Lastly, the app also preserves your history stack– if you follow a t.me link to another message in a chat, you can return to the firstmessage with the? button.

While this channel has been a little quiet for the last three months, the app continued to evolve.

? Today, WebK introduces a redesigned Emoji and Sticker Panel – try the collapsible section for default emoji categories and the scrollable bar for your custom emoji sets.

The new Panel features a beautiful blur effect on most desktop browsers and allows you to send or edit messages containing custom emoji. (All users can try out this feature in their Saved Messages). Copy and paste are also available.

In the Stickers tab, you can now add or remove stickers from favorites, send without sound or individually delete them from the Recents section.

? Preview Stickers and Emoji
You can now get a closer look at stickers and emoji, both in the panel and in chats. Click and hold, then hover your cursor over the one you'd like to see in better detail.

Stickers are now rendered more efficiently, using fewer resources and saving battery. Custom Emoji have also had more improvements since their launch in late August.

⚡️ Downloading Files
The download flow has been reworked from scratch. When you download something, the app uses your connection in the most efficient way possible. Premium users will notice how dramatically fast the app downloads files for them – a little demo is available here.

Large files of up to 4 GB are now supported for both upload and download. There is also support for native downloading in certain browsers – your browser will place active downloads on the instrument bar.

? Payments 2.0
Significant optimizations were added to smoothly process payments in any browser, and adding familiar functionality from other Telegram apps. Bot payments, @donate invoices and more are supported – including the ability to subscribe to Telegram Premium with @PremiumBot.

Dozens of bug fixes were also made to the app – but those can be a bit boring to read. If you ever come across a bug in the app, make sure to let us know on the Bugs and Suggestions Platform.
