What is the '@ Prefix' Used for in npm Packages?

Understanding the "@ Prefix in npm Packages

In npm commands, the "@" prefix is commonly used to indicate scoped packages. Scoped packages are a feature introduced in npm to organize and namespace packages. Here's an explanation of their significance.

What are Scoped Packages?

Scoped packages are packages published under the namespace of a specific user or organization on npm. This unique prefix ensures that package names are distinct within their scope, rather than needing to be globally unique.

Benefits of Scoping

Scoped packages provide several advantages:

• Clarity of Ownership: Organizations can clearly identify their official packages by including their namespace.
• Reduced Name Clashes: Within a scope, package names can be reused without conflicting with similar names from other namespaces.

Installation Syntax

To install a scoped package, you need to specify the "@" prefix followed by the package's name. For example:

npm install @angular/router --save

Visibility of Scoped Packages

Public scoped packages are now visible in npm search results. However, private scoped packages remain hidden unless explicitly published by their creators.
