@mariuszgil @boilingfrogspl That's why I consider @boilingfrogspl the most valuable IT conference at least in Poland. Being there is like battery charging for any IT worker who want's to learn more than code.

I was considering to replace my Prettier + Eslint setup with @biomejs but I am that oldschool frontend dev who writes CSS ;) and there is no support for CSS and HTML yet. But Biome is still very interesting project.

@mariuszgil @cytrowski @tomasz_ducin Czy to jeszcze BSD !?
Jako ten gupi frontend dziekuje, bo mega konkretna wiedza niezaleznie od skali w ktorej sie pracuje.

TypeScript is not making your life terrible. It's just showing you how terrible your life already is.

@fireship_dev came with super useful content once again. This time it's all about React compiler and other shiny stuff in incoming v19 https://t.co/SLaOnrY4HT

@rwieruch Thank @rwieruch :) Coffee with your blog posts is always enjoyable. Btw, I learned react from your awesome ebook back in 2017 :)

"React Trends in 2024" by @rwieruch #ReactJS https://t.co/oa1YmYlrtG is a perfect thing to read during the morning coffee :)

I just did 8 kyu kata at Codewars and I learned that about +x and -x operators :) My conclusion is that even trivial challenges can teach something interesting. Dopamine level boosted.

@wesbos the one which yields "TIPS" from the background :)

Pure gold for every frontend dev 🤯

[Tomasz Ducin @tomasz_ducin]

So I'll be running a series of
🔥 #Architecture #Focus 🔥
posts 🤘
for #frontend devs in #angular #react and #vue projects

The 🧵 below will aggregate all of them ⬇️

Do you remember when you joined X? I do! And yes, I am so old :P #MyXAnniversary

🔥 #Architecture #Focus 🔥

Why should your system be DESIGNED FOR FAILURE? 🤕

DESIGN FOR FAILURE is:
💥 an architectural approach 🏗️
💥 where errors and unavailability are system’s first-class citizens 👊
(failure is as important as happy path)
💥 we plan for quick recoveries 🏎️ rather than error-free systems 💥
💥 so that, if an outage happens, we’re not doomed ☠️

wait, isn't try..catch enough? 😏
👎 certainly not...

WHY?
🧨 everything would eventually fail at some point
🧨 what would be business and technical CONSEQUENCES?
🧨 if one part of the system fails, would the ENTIRE SYSTEM GO GOWN 🥶 as well?
🧨 failures can COST lots of 💸💸💸
🧨 your business will love you 😘 really 😘😘😘

HOW?
🤧 test errors
🤒 test failures
🤕 test outages
🥴 test, test, test...

no, but seriously, HOW?
📝introduce RETRIES, especially with EXPONENTIAL BACKOFF (coming up!)
📝consider adding CIRCUIT BREAKERS (coming up!)
📝implement SYSTEM OBSERVABILITY (coming up!)
📝provide CORRELATION IDs/TOKENs (coming up!)
📝limit TEMPORAL COUPLING (coming up!)
📝identify SINGLE POINTs OF FAILURES (coming up!)
📝test failure scenarios via CHAOS ENGINEERING (coming up!)

WHAT to test?
💣 how does the UI handle network errors?
💣 is the user properly informed if a certain service goes down?
💣 does the user lose their local state?
💣 how does the UI recover?
💣 if anything goes wrong, do developers know IMMEDIATELY? (observability)
💣💣💣 are above tests automated?
