Learn how to fix: What is the meaning of the "at" (@) prefix on npm packages?.
📋 Table of Contents
The "at" (@) prefix on npm packages is used to specify the version of a package. When you run the command `npm install @angular/router --save`, it's not installing the entire `@angular` namespace, but rather a specific version of the `router` module from that namespace.
🔧 Why is this used?
- [Cause]
👉 Understanding the `@` prefix
The `@` symbol is used to denote a namespace or a package. In this case, it's indicating that you want to install a specific module from the `@angular` namespace.
- Example: If you installed `@angular/core`, you would use `@angular/core` instead of just `core.
The version number
- Example: `@angular/router` specifies the router module from the `@angular` namespace, while `@angular/router@latest` would install the latest version of that module.
🎯 Final Words
By using the `@` prefix, you can specify a specific version of a package and avoid conflicts with other versions. This is especially useful when working on projects that require a specific version of a dependency.
