Introduction
Aaj ke samay me web development me React.js aur Next.js dono kaafi popular technologies hain. Lekin naya seekhne wale developers confuse ho jaate hain ki:
👉 React sikhein ya Next.js?
👉 Dono me farak kya hai?
👉 Kaun better hai? Freelancing ke liye kya use karein?
To chaliye, is article me React aur Next.js ka simple comparison karte hain — Hindi me, real examples ke saath!
React.js Kya Hai?
React ek JavaScript library hai jo Facebook ne banayi thi. Ye sirf frontend user interface banane ke kaam aati hai, jaise buttons, forms, layouts, etc.
Key Points:
- Component-based structure
- Sirf client-side rendering karta hai
- SPA (Single Page Applications) banane ke liye use hota hai
- Developer ko routing, SEO, server-side handling khud banana padta hai
Next.js Kya Hai?
Next.js ek React ka framework hai. Iska matlab ye React par hi based hai, lekin uske upar extra powerful features deta hai jaise:
- Server-side rendering (SSR)
- Static site generation (SSG)
- Built-in routing
- SEO optimization
- Image optimization
Example:
Agar React ek engine hai, to Next.js uska full-featured car version hai.
React vs Next.js – Difference Table
| Feature | React.js | Next.js |
|---|---|---|
| Type | Library | Framework (React based) |
| Routing | Manual (React Router use hota hai) | Automatic (File-based routing) |
| Rendering | Client-Side Only | Client + Server (SSR + SSG) |
| SEO Friendly | Nahi (default) | Haan (out-of-the-box) |
| Performance | Depends on your setup | Highly optimized by default |
| API Support | Nahi (external server needed) | Built-in API routes |
| Deployment | Vercel, Netlify, Firebase, etc. | Vercel par best optimized |
| Learning Curve | Easy | Moderate (thoda setup aur concept extra) |
Kab React Use Karein?
React use karein jab:
- Aap ek basic SPA banana chahte hain
- Aap beginner ho aur pehle frontend concepts seekhna chahte ho
- Aapko zyaada custom control chahiye without opinionated structure
Example Use Case:
- To-do app
- Portfolio website
- Simple dashboard
Kab Next.js Use Karein?
Next.js use karein jab:
- Aapko SEO important hai (e.g. blog, e-commerce site)
- Aap chahte ho fast performance with SSR/SSG
- Aapko production-ready app banana hai
Example Use Case:
- Blogging site (like rahulguptaweb.com)
- News portal
- Ecommerce website with fast loading
Freelancing Ke Liye Kya Best Hai?
Freelancing projects me agar client chah raha hai ki website Google me rank ho aur fast load ho, to Next.js best hai.
Lekin agar client ek basic interactive site maang raha hai jisme SEO ka farak nahi padta, to React.js bhi kaafi hai.
Conclusion
| Short Summary |
|---|
| React ek library hai jo frontend banata hai. |
