Node.js – Full Course for Beginners

Decentralized applications (DApps) backends differ significantly from traditional backends, primarily because they rely on blockchain technology for decentralized data storage instead of centralized databases or object storage. However, many core technical principles – such as API design, data flow, and system architecture—remain similar.

To transition into DApp development, start by mastering standard backend concepts:

• Learn how frontends and backends communicate (HTTP, WebSockets).
• Build APIs using frameworks like Node.js & Express.
• Understand databases (SQL & NoSQL) and authentication.
• Practice deploying scalable applications.

Once comfortable with traditional backends, explore blockchain integration (Ethereum, Solidity, smart contracts) to leverage decentralization.

Key Takeaway: Strong backend fundamentals make transitioning to DApp development smoother.
