Managing React Dependencies with npm and Node.js

Dependency management is the foundation of modern JavaScript development, but the tooling ecosystem can often feel overwhelming for newcomers. This course clarifies the essential concepts needed to build stable and maintainable applications. By the end of this course, you will understand the entire package lifecycle, from project initialization to maintenance, allowing you to effectively organize and maintain the external libraries your React projects rely on. What you'll learn: * Understand the fundamental architecture of Node.js and the Node Package Manager (npm). * Configure new projects using package.json and differentiate between local, global, and development dependencies. * Apply semantic versioning principles and interpret the critical role of package-lock.json for reproducible builds. * Master the creation and execution of custom build, test, and utility commands using npm scripts. * Learn how to manage external type definitions and resolve common dependency conflicts. * Implement basic security practices by running package audits and resolving known vulnerabilities. We start by defining key terminology and then move step-by-step through project setup and hands-on package installation. The focus is on practical configuration and troubleshooting techniques applicable to any modern JavaScript project. This course is designed for absolute beginners to JavaScript tooling and React development who need a solid foundation in dependency management. No prior experience with Node.js or npm is required.
