Engagement
18 posts held, back to 13 July 2026 — the reader has not yet reached the start of this channel’s public history, so older posts may sit further back, unread. Read across 1 page of Telegram’s post history, 20 posts per page.
Nothing published in the last 30 days. ERR and ER are rolling 30-day measures, so there is nothing to compute — we hold 18 posts for this entry, the most recent from 25 July 2026. An engagement rate over an empty window would be a number about nothing.
Reaction mix
9 reactions across 7 posts, in 4 distinct kinds. The most used accounts for 55.6% of them.
| Reaction | Count | Share | Share, drawn |
|---|---|---|---|
| ❤ | 5 | 55.6% | |
| 🔥 | 2 | 22.2% | |
| 👌 | 1 | 11.1% | |
| 👍 | 1 | 11.1% |
No sentiment is inferred, and none should be read in. This table is ordered by count and by nothing else. Emoji do not carry stable meaning across languages or communities — 🙏 is thanks in one channel and mourning in another — so we publish which ones were pressed and how often, and pass no judgement on what an audience meant by them.
Precision. Telegram publishes reaction counts per emoji and short-forms each one — 4.34K, 1.2M — so any single kind at or above 1,000 reaches us at three significant figures, and only counts below 1,000 are exact. The shares above are ratios of those figures and carry the same error. This is also why the total here can differ slightly from a reaction total printed elsewhere on the page: both are sums of the same rounded parts, taken over samples with different edges.
Coverage. Reactions were read on 8 of the 18 sampled posts in this sample. Summed by Telegram’s own count on each post — not by adding up the per-emoji breakdown above — those same posts carry 9 reactions in total: the kind of figure the paragraph above means by “a reaction total printed elsewhere on the page”.
Measured over the 18 most recent posts we hold, published 13 July 2026 to 25 July 2026, using the newest reading held for each. Telegram Stars are excluded: they are a payment, not a reaction, and they have their own section.

🛡 Error Boundary آخرین خط دفاعی حتی اگه همه جا error handle کنین یه جایی یه خطای پیشبینینشده میاد و کل صفحه crash میکنه Error Boundary دقیقا برای همینه — یه کامپوننت که خطاهای runtime رو میگیره و بهجای crash، یه UI جایگزین نشون میده ⭕️ ( عکس ضمیمه شده ) ⚠️ یه نکته مهم : Error Boundary فقط خطاهای render-time رو میگیره — خطاهای داخل event handler و async function رو نمیگیره. اونا رو باید دستی handle کنین منبع رس…
یه چیزی که توی اکثر پروژهها میبینم error handling اصلا وجود نداره — یا اگه هست، اینشکلیه : try { const data = await fetchUser(id); setUser(data); } catch (e) { console.log(e); // 👈 و تموم } کاربر یه صفحه سفید میبینه، هیچکس نمیدونه چی شد، و debug کردن کابوس میشه اول باید error type ها رو از هم جدا کنین => ⭕️ ( عکس ضمیمه شده اول ) حالا توی fetch wrapper اینا رو handle میکنیم ⭕️ ( عکس ضمیمه شده دوم ) و توی ک…
🌿 Branch naming یه چیز کوچیک که کار تیم رو راحت میکنه وقتی توی یه تیم کار میکنین و ۱۰ تا branch دارید، اگه اسمگذاری استاندارد نباشه : git branch # خروجی: foad-changes new-feature fix test2 modal-thing-foad هیچکس نمیدونه این برنچها هرکدوم دقیقا برای چی هستن یه convention ساده : # feature جدید feature/user-profile-page feature/add-payment-gateway # رفع باگ fix/cart-total-calculation fix/mobile-nav-over…

🔀 یه چیزی که توی اکثر تیمها غلط انجام میشه : همه روی برنچ main کار میکنن یه نفر یه چیزی push میکنه، نفر بعدی conflict میگیره، یه ساعت وقت تلف میشه برای چیزی که اصلا نباید اتفاق میفتاد یه workflow ساده که این مشکل رو حل میکنه : # ۱. برای هر feature یه branch جدا git checkout -b feature/user-authentication # ۲. commitهای کوچیک و معنادار git commit -m "feat: add login form validation" git commit -m "feat: integrate …

Showing the 12 most recent of 18 posts we hold for @foad_labs. View and reaction counts are the latest single reading for each post, not a live figure, and a recent post is still accumulating both. A view count marked ≈ was rounded by Telegram before we ever saw it — t.me prints views in full below 1,000 and to three significant figures above, so ≈1,200,000 means somewhere between 1,150,000 and 1,249,999. Unmarked counts are exact. Text is reproduced from the public post preview and truncated for length.
Forward network
Republished by
Channels on the register that have forwarded this channel's posts into their own feed.
Republishes
Channels on the register whose posts this channel has forwarded.
Built only from forwarded posts we have actually read, on both sides. Coverage is early and deliberately incomplete: a missing link means we have not read the post that would prove it, never that the relationship does not exist. Counts are distinct forwarded posts observed, so they only ever go up as we read more.
Mentions
Names
Channels on the register whose handles appear in this channel's posts.
A mention is a weaker signal than a forward and is counted separately for that reason — naming a channel is not republishing it, and a handle in a post body is easy to place deliberately. The post counts beside each row below are distinct posts in which the handle appeared, from posts we have read on both sides — the “Named by N registered channels” figure above is a different count, of distinct NAMING CHANNELS rather than posts, and is not the sum of the rows under it.
