npm vs. npx: What’s the difference?

Npm and npx are essential tools in the Node.js ecosystem, each serving distinct functions. Npm, or Node Package Manager, is primarily used for installing and managing packages and dependencies within Node.js projects, offering features like version control and script automation through the package.json file. It supports both local and global installation of packages, making it a staple for long-term dependency management. In contrast, npx is designed to execute Node.js packages directly without requiring installation, making it ideal for one-off tasks or testing tools without adding them to the system permanently. Npx simplifies the execution of command-line tools by running them directly from the npm registry, avoiding the clutter of global installations. While npm is preferred for setting up projects and managing their dependencies, npx is favored for temporary tasks and quick project scaffolding. Together, they provide a comprehensive workflow for JavaScript developers, balancing the need for permanence and flexibility in package management and execution.
