Node and npm Essentials for Test-Driven Development

Setting up a reliable development environment is the first and most crucial step in modern JavaScript engineering. This text-based course guides you through the foundational concepts of Node and npm, establishing a rock-solid workflow designed specifically for test-driven development. You will transition from a manual setup to a structured, professional development environment. By understanding how dependencies, package managers, and test runners interact, you will gain the confidence to initialize, configure, and maintain robust React projects with a test-first mindset. What you'll learn: - Understand Node.js core concepts, runtime environments, and how to execute JavaScript outside the browser - Manage project dependencies, semantic versioning, and package locks using npm - Configure modern testing environments using popular runners like Jest or Vitest - Apply test-driven development (TDD) principles to write reliable React components - Set up modern ES Modules and manage environment variables securely - Practice initializing and structuring scalable JavaScript projects from scratch This course begins with fundamental terminology, installation steps, and package management basics before moving into practical configuration files and test-driven workflows. Through clear written explanations and structured code exercises, you will build a complete understanding of how modern JavaScript tooling fits together. This course is designed for beginning developers and React enthusiasts who want to establish a professional local development workflow. No prior experience with Node, npm, or testing is required, though a basic understanding of JavaScript is helpful.
