Purpose of node_modules
- Code Reusability: Node modules allow users to reuse existing code instead of reinventing the wheel. This can save time and effort by leveraging the work of others in the NodeJS community.
- Modularity: Node modules promote a modular approach to software development. By breaking down code into smaller, manageable modules, users can build more maintainable and scalable applications.
- Dependency Management: Node modules help manage dependencies within a project. Dependencies are specified in a project’s package.json file, and npm handles the installation and versioning of these dependencies.
- Encapsulation: Node modules encapsulate functionality, making it easier to understand and reason about different parts of an application. This improves code organization and helps prevent namespace collisions.
- Community Contribution: Node modules foster collaboration within the NodeJS community. Developers can share their modules with others, contribute to existing modules, and provide feedback to improve the ecosystem as a whole.
What is the purpose of the ‘node_modules’ folder ?
The node_modules
folder is a directory in NodeJS projects that stores third-party libraries and dependencies. It’s essential for managing dependencies, which are packages or modules that a NodeJS project relies on.
When you install a package using npm or Yarn, these tools download the package along with its dependencies and save them in the node_modules
folder. This folder ensures that all required dependencies are available for the project to run successfully.
