Part 2 of this
➡️learned Langgraph
LangGraph is a powerful library built on top of LangChain that focuses on creating stateful, multi-agent workflows using a graph structure. Let's start with the fundamental structure of LangGraph.

past few days i am learning how to build ai agent till now i have learnt these concepts
➡️Ai agents are smart systems , often powered by (LLLMs) like GPT-5 that take your goal , figure out the steps , and then use tools to get things done with little to no supervision . 🧵

Let's go deep in promises ....
A Promise is an object that embodies the eventual result (or error) of an asynchronous operation
we say that a Promise is pending when the asynchronous operation is not yet complete,

❓ EventEmitter vs callbacks when to use them ..
💡 The general differentiating rule is semantic: callbacks should be used when a result must be returned in an asynchronous way, while events should be used when there is a need to communicate that something has happened.

Skipping KISS as a developer is basically saying, “Why make it simple when I can leave behind a puzzle even I won’t solve twice?”

Another important and fundamental pattern used in Node.js is the Observer pattern. Together with the Reactor pattern and callbacks, the Observer pattern is an absolute requirement for mastering the asynchronous world of Node.js.

In Node.js, errors thrown inside asynchronous callbacks behave differently from synchronous ones. When an error occurs in synchronous code, a try...catch block can handle it because it runs in the same call stack.

📚 Started reading Node.js Design Patterns today.
Finished first 2 chapters.
• Node follows a small modules philosophy — simple, reusable packages.
• Node handles massive concurrency using non-blocking I/O event loop, even with a single🧵

Os contribution Paswrd Reset Security Fix: github.com/TeamShiksha/openl…
Fixed a small but important issue where users could reset their password to the same as their old password.
Added a check that compares the new password with the stored hash and blocks reuse to improve security.

Just completed 1 month with Team Shiksha 🚀
Had the chance to raise a couple of PRs and learn a lot along the way. Sharing two things I worked on recently:
1️⃣ Subscription Middleware pr-Link: github.com/TeamShiksha/openl…
Built a middleware-based system to handle API access control.

Help needed..
I’ve mostly worked with basic HTTP requests so far, but now I want to challenge myself and design something more realistic.
I’m currently stuck on how to structure and make it work properly — this is a personal learning project, and I’m open to guidance.

Just completed 90% of my first advanced backend project Food Ordering Backend (real-time, ratelimit,backgroundjobs,reusablecode).
What I built👇
• Clean code pattern across all services
• Background workers for emails, auto cancel order
• rate limiting
8 Nov 2025
why background jobs are a must in production systems.
If you send OTPs or emails directly inside your signup API, your users might face timeouts when SMTP slows down.
Use queues .
Create the user instantly, send emails in the background.
Open for feedback if i am wrong >>
