@surajtwt_ Awesome, very nice

How was the class guys? Drop your experience below⬇️

Today's @ChaiCodeHQ Web Dev class: DOM Events Covers a lot of ground — • addEventListener vs onclick (hint: always use the first one) • Event bubbling & capturing — that true/false flag in addEventListener actually matters • stopPropagation() to control how far an event travels • Event delegation — one listener on the parent instead of N listeners on every child • preventDefault() for anchors, forms, etc. Ended with building a Kanban board using drag and drop entirely with DOM events. Event propagation is one of those things that looks weird at first, but explains half of your frontend bugs once you get it. Thank you @surajtwt_ sir for this amazing session. also thank you all the TA's @nirudhuuu @yntpdotme #JavaScript #WebDev #ChaiCode

@VinnyMadaan3 @affancodez @yntpdotme Archilinux is lightweight than Ubuntu, I am using Zorin which is also good one.

@affancodez @yntpdotme Arch lightweight hai ya ubuntu? Any specific reason for arch?

Hope society will accept me 🙂 Rip my valo acc @yntpdotme

Also covered why @piyushgarg_dev doesn't prefer Azure , a funny story 😅.

Today’s class was about • Understood core concepts of distributed caching • Covered consistent hashing • Started interview-focused practice (read-through cache, designing distributed cache) • Explored tools like Redis, Memcached, Valkey • Learned eviction policies & LRU cache • Touched the basics of AWS, Hypervisor A solid step towards mastering scalable system design concepts. 🚀 Thanks to @Hiteshdotcom @piyushgarg_dev @yntpdotme @nirudhuuu @ChaiCodeHQ @surajtwt_ #chaicode #systemdesign #cohort

Just finished a system design session on Caching & Distributed Systems 🔥 — here's the full breakdown in a thread 🧵 1/ Why cache at all? If a computation takes 30-40s, you cache the result. Next time someone asks — it's instant. That's the entire idea. 2/ Redis vs Postgres Redis = RAM → blazing fast, limited size Postgres = Disk → slower, persistent, large Pick based on your use case — not hype. 3/ Cache HIT vs MISS HIT → serve from Redis ✅ MISS → fetch from DB → update Redis → serve This pattern = Read-Through Cache 4/ TTL is your best friend Set expiry on every cache key. 24hrs for slow-changing data. 5min for real-time data. No TTL = stale data forever 💀 5/ Eviction Policy: LRU When storage is full, kick out the Least Recently Used item. This is how Redis stays lean under pressure. 6/ Consistent Hashing 🔄 Distributed cache across 3+ nodes? Use a hash ring. hash(key) % n → determines the partition Add/remove a node? Only a fraction of keys move. Not all. 7/ Infrastructure ladder: Data Center → Hypervisor (Proxmox) → VMs → VPS → Cloud (AWS/Azure/GCP) More abstraction = less control but less headache. Thank you @piyushgarg_dev sir for the awesome session and we missed you today @Hiteshdotcom sir and thank you all the TA's @nirudhuuu @ChaiCodeHQ #SystemDesign #Redis #Caching #DistributedSystems #ChaiCode #BackendEngineering

Wrote a blog on how Kafka works internally , in such a way that a kid can understand. Here is the link blogs.abhijitmone.com/kafka-explaine… Check this out. and let me know in the comments. @ChaiCodeHQ @Hiteshdotcom sir @piyushgarg_dev sir @nirudhuuu @yntpdotme

Day-6 System Design Cohort Learned about CQRS today and it changed how I think about databases. Key learnings: → Never use the same model for reads & writes → Commands mutate state, Queries just fetch → Each side can have its own optimized DB → Sync via events (SNS, Kafka, etc.) → Tradeoff = eventual consistency (and that's fine) CQRS is not over-engineering. It's just good architecture. Thank you @Hiteshdotcom and @piyushgarg_dev sir for this amazing session. Also thank you TA's @nirudhuuu and @yntpdotme. @ChaiCodeHQ #SystemDesign

@Dipali2Sharma @surajtwt_ @Hiteshdotcom @piyushgarg_dev @nirudhuuu @yntpdotme @ChaiCodeHQ Very nice !!!

Dom mini project 2. Dynamic List Creator Live link: relaxed-maamoul-546f5f.netlify.app Git repository: github.com/sharmadipali/D… Guidance of @surajtwt_ @Hiteshdotcom @piyushgarg_dev @nirudhuuu @yntpdotme @ChaiCodeHQ

Today: Express.js Middleware It confused me at first. Then it clicked — Middleware = just a function between request & response. It can: → Validate data → Log requests → Handle auth → Control API flow Wrote my first custom middleware today and the whole Express lifecycle finally made sense 🔥 Thank you @Hiteshdotcom and @piyushgarg_dev sir for the amazing session and also thanks to TA's @nirudhuuu @yntpdotme @surajtwt_ @ChaiCodeHQ

Todays class summary. What happens when you run `node filename.js`? → Init → top-level code → event loop starts Loop phases: 1. Expired callbacks 2. I/O polling 3. setImmediate 4. Close callbacks Heavy tasks? Offloaded to a thread pool. That's Node internals in a nutshell 🔥 Thank you for the amazing session @Hiteshdotcom @piyushgarg_dev sir and also thanks to TA's @nirudhuuu @yntpdotme #NodeJS #JavaScript #Eventloop

Started with git hub labs , next set of assignments are here. here we go. @nirudhuuu @Hiteshdotcom @ChaiCodeHQ @yntpdotme

@TusharNebhnani_ @tejasxdev @Hiteshdotcom @piyushgarg_dev @nirudhuuu @yntpdotme @surajtwt_ @ChaiCodeHQ You can try contenteditable attribute of html

@tejasxdev @Hiteshdotcom @piyushgarg_dev @nirudhuuu @yntpdotme @surajtwt_ @ChaiCodeHQ How you added the text edit functionality without using prompt can u teach me?

Assignment 2 of the DOM is done ✅ @Hiteshdotcom @piyushgarg_dev @nirudhuuu @yntpdotme @surajtwt_ @ChaiCodeHQ #chaicode

Amazing class @janhvi_1508 , good session. Congrats on the bounty.

@janhvi_1508 @nirudhuuu @Hiteshdotcom @piyushgarg_dev Congratulations !!

Still can’t believe I am part of the React Native an exclusive cohort! Thank you @nirudhuuu Sir for this opportunity. Never imagined the tables would turn like this & I will be one of the 20 students. Feeling gratitude & blessed!! @Hiteshdotcom @piyushgarg_dev #chaicode

Done Async session 2 in System Design covered by @Hiteshdotcom and @piyushgarg_dev sir, got in depth understanding about when to use Kafka, SQS, Bull MQ, Rabbit MQ. Also had a discussion about ConsumerGroupId and Partitions -> and also understood the beauty of kafka Thanks @ChaiCodeHQ @nirudhuuu #SystemDesign

Day 4- Understanding Async workflow system and Online judge system such as leetcode in detail, thank you very much @Hiteshdotcom and @piyushgarg_dev sir for explaining it in such detail, such an amazing experience. and also thanks to TA's as well @nirudhuuu @yntpdotme , @ChaiCodeHQ #chaicode #SystemDesign #hiteshchoudhary #piyushgarg #leetcode

World Cup bhi jeet gaye aur typescript pe bhi victory. Next week is gonna be hell. @ChaiCodeHQ @Hiteshdotcom @piyushgarg_dev @nirudhuuu @yntpdotme
