Today’s focus: JWT & Authentication 🔐
• Learned how JWT tokens work
• Key concept: passwords are hashed, not encrypted
• Hashing = one-way (can’t reverse) 🧠
Understanding auth basics is critical for backend systems 🚀

Today’s focus: Production-grade APIs ⚙️

Learned structuring backend apps with Express + MongoDB (Mongoose), folder architecture, and env setup 🔐

Also explored ORM/ODM and why separation of concerns matters 🧠

Today’s cohort session: Express.js basics

Built simple APIs with GET & POST routes, used query params and route params, and learned middleware (app.use).

Also parsed JSON using express.json() and sent responses with res.json() 🚀

Big Thanks to: @Hiteshdotcom @piyushgarg_dev

Today’s cohort session: Node.js internals ⚙️

Node.js = V8 + C++ + libuv

🧠 V8 runs JavaScript
🔗 C++ bindings connect JS with system operations
🔄 libuv powers the event loop & thread pool

Thank You @piyushgarg_dev and @Hiteshdotcom Sir.

In case you missed the notification

[Balraj Singh @ByteLife]

My coding and English skills need work. I plan to improve both by practicing daily. Consistency is the key to success.

I am currently part of Chai Code’s Web Dev 2.0 Cohort. The learning method is highly efficient—better than anything I have experienced before.
