NPM LN - JavaScript

NPM LN is a command used in the Node Package Manager (NPM) that creates a symbolic link between packages, which helps in the development process by allowing the use of local packages instead of installed ones.

The basic syntax of NPM LN is:

npm ln <source-package> [--global] [--link]

• <source-package>: The name of the package that you want to link
• --global (optional): Links the package globally instead of locally
• --link (optional): Creates symbolic links instead of hard links

Advantages

• Saves Disk Space: Instead of installing the same package multiple times, symbolic links only need to link to a single instance of the package.

• Facilitates Development: With NPM LN, you can easily work with local packages instead of installed ones, which can be beneficial for debugging and customizing packages.

Example

Suppose you want to create a symbolic link for a package named my-package and link it globally. You can use the following command:

npm ln my-package --global

Conclusion

NPM LN is a useful tool for developers who want to save disk space and facilitate the development process by using local packages. Its simple syntax and useful features make it a popular tool among JavaScript developers.
