The nrm command is a Node.js package that allows you to easily switch between different npm registries. It simplifies managing multiple registries, such as the official npm registry, a private registry, or a mirror registry, especially useful when developing across different environments or for organizations with specific registry requirements. nrm provides a straightforward command-line interface to list available registries, add new ones, switch between them, and test their latency.

nrm improves workflow efficiency by eliminating the need to manually configure the npm registry using commands like npm config set registry repeatedly. Using nrm, developers can quickly change the active registry based on the current project or development context, ensuring the proper packages are fetched from the intended source. It enhances developer productivity and simplifies package management in diverse npm environments.

nrm only manages the registry configuration for the current user. It does not modify the global npm configuration unless explicitly told to. Also, remember to install nrm globally using npm install -g nrm.

To install nrm, use the following npm command: npm install -g nrm. This will install nrm globally, making it available from the command line.

nrm stores the registry configurations in a simple JSON format. This file is typically located in the user's home directory. While you can manually edit this file, it is highly recommended to use the nrm add and nrm del commands to manage the registries.
