Description

Introduction
This training focuses on bridging the gap between frontend and backend development using Angular or React with Node.js. Participants will learn how to build seamless, full-stack applications where the frontend interacts efficiently with backend services. The course emphasizes hands-on integration, API communication, authentication, error handling, and deployment best practices. Learners will gain practical experience in connecting user interfaces to server-side logic and databases, enabling them to build complete, production-ready applications.

Prerequisites
Participants should have basic knowledge of HTML, CSS, and JavaScript. Familiarity with Angular or React fundamentals and Node.js basics will be helpful. Understanding of HTTP protocols, REST APIs, and JSON is recommended. Some experience with databases such as MongoDB or SQL will be beneficial but is not mandatory. A willingness to work on hands-on integration projects is essential.
