Namaste dosto! Aaj hum shuru kar rahe hain ek naya tutorial series jisme hum NodeJS ke bare me baat karenge. NodeJS ek open-source, cross-platform JavaScript runtime environment hai jo server-side programming ke liye use hota hai. Yeh Node.js JavaScript engine par chalne wala hai jo V8 JavaScript engine par adharit hai.

Is lecture me hum NodeJS ke introduction par focus karenge aur basic concepts pe baat karenge. Yeh ek complete course hoga jisme aap NodeJS ke advanced features aur functionality ko bhi seekhenge. Is course ke ant me aap ek certification bhi prapt kar sakte hain jo aapke career me madadgar sabit ho sakta hai.

To chaliye shuru karte hain! Pehle hum NodeJS ke basic introduction pe baat karte hain.

NodeJS Introduction

Node.js 2009 me Ryan Dahl ke dwara develop kiya gaya tha, jise usne Chrome V8 JavaScript engine ke adhar par develop kiya tha. Node.js ek event-driven, non-blocking I/O model ka use karta hai jo scalable aur efficient server-side applications develop karne me madad karta hai. Isme JavaScript ka use kiya jata hai jo client-side aur server-side dono me code re-use karne ki suvidha deta hai.

NodeJS Features

1. Single-threaded Event Loop: NodeJS ek single-threaded event loop model ka use karta hai jisse multiple requests ko handle kiya ja sakta hai bina performance aur scalability par koi prabhav padta.

2. Non-blocking I/O: NodeJS asynchronous nature ke karan I/O operations ko non-blocking tarike se handle karta hai, jisse applications ki performance improve hoti hai.

3. Cross-platform: NodeJS cross-platform hai jiska matlab hai ki aap Windows, Linux, MacOS jaisi kisi bhi operating system par NodeJS code run kar sakte hain.

4. Module System: NodeJS ka module system bahut powerful hai jisme aap third-party modules ko import karke use kar sakte hain.

5. NPM (Node Package Manager): NodeJS ke sath sath NPM bhi aata hai jo aapko thousands of pre-built packages provide karta hai jo development process ko speed up karta hai.

NodeJS Installation

NodeJS ko install karne ke liye aap official NodeJS website par visit kar sakte hain aur latest version ko download karke install kar sakte hain. Installation process bahut simple hai aur kuch hi steps me complete ho jata hai.

NodeJS Basic Concepts

1. Creating a Server: NodeJS me server create karne ke liye aap http module ka use kar sakte hain jisse aap server create kar sakte hain.

2. npm: NodeJS me npm (Node Package Manager) ka use hota hai jisse aap third-party libraries ko install aur manage kar sakte hain.

3. Callback Functions: Callback functions NodeJS me bahut important hain jisse asynchronous code ko handle kiya ja sakta hai.

4. Events: NodeJS me events ek crucial part hain jisse aap events handle kar sakte hain aur code ko event-driven banane me madad milti hai.

To yeh the NodeJS ke basic concepts jo hum is lecture me cover kiye hain. Agar aapko koi specific topic ya concept me interest hai to aap comment karke hume bataye taki hum future lectures me uss topic ko cover kar sake.

Is course ka ant tak hum NodeJS ke advanced features, web development me NodeJS ka use, RESTful API development, database connectivity, security features aur bohot kuch sikhayenge. Is course ke ant me aap ek certification bhi prapt kar sakte hain jo aapke resume me ek extra edge dega.

Umeed hai ki aapko yeh lecture pasand aaya hoga. Agar aapke koi sawal ya sujhav hai toh aap hume likh kar bata sakte hain. Hum agli lecture me fir se milenge. Dhanyavad aur sukhriya!
