Simplifying Node.js Version Management with FNM

Managing Multiple Node.js Versions

Managing multiple Node.js versions on a single machine can be a tedious and time-consuming task. The traditional approach involves manually installing and uninstalling different versions, which can lead to version conflicts and wasted time.

What is FNM?

FNM is a Node version manager written in Rust, designed to simplify the process of installing, managing, and switching between different Node.js versions. With FNM, developers can install specific versions of Node.js, list all available versions, and switch between them with ease.

Why Use FNM?

FNM offers several advantages over traditional Node.js version management methods. These include:

• Speed: FNM is built with Rust, making it faster and more efficient than other Node version managers.
• Simplicity: FNM provides a simple and intuitive command-line interface for managing Node.js versions.
• Flexibility: FNM allows developers to install and manage multiple Node.js versions on a single machine.

Getting Started with FNM

To get started with FNM, simply install the software using the installation script or by downloading the binaries from the Releases page. Once installed, verify that everything works by running the following command:

fnm --version

Managing Node.js Versions with FNM

FNM provides several commands for managing Node.js versions. These include:

• Installing a specific version: Use the following command to install a specific version of Node.js: 

  fnm install <version>

• Listing all available versions: Use the following command to list all available Node.js versions: 

  fnm ls

• Switching between versions: Use the following command to switch between different Node.js versions: 

  fnm use <version>

Uninstalling Node.js Versions

To uninstall a specific Node.js version, use the following command:

fnm uninstall <version>

This will remove the specified version from your system.

Alternatives to FNM

While FNM is a popular choice for managing Node.js versions, there are alternative tools available. These include:

• NVM: A Node version manager that allows developers to install and manage multiple Node.js versions.
• Volta: A Node version manager that provides a simple and intuitive command-line interface for managing Node.js versions.
