Introduction

Nodapt (/noʊˈdæpt/) is a command-line tool designed to work with multiple Node.js versions. It automatically selects and uses the appropriate Node.js version to run commands based on the version constraints specified in the package.json file.

Background

When developing Node.js projects, it is common to switch between different Node.js versions. For example, Project A might require 16.x.y, while Project B uses 20.x.y.

However, traditional global version management tools (e.g., nvm) often fall short in meeting these needs due to the following issues:

1. Limited cross-platform support: nvm is not very convenient to use on Windows.
2. Pre-installation requirements: nvm requires pre-installing specific versions, which is not ideal for CI/CD environments.
3. Lack of Monorepo support: In Monorepo setups, different subprojects may require different Node.js versions, which nvm cannot handle effectively.

To address these challenges, Nodapt was developed. It automatically selects and installs the appropriate Node.js version to run commands based on the version constraints in package.json.

Features

• Cross-platform support (Mac/Linux/Windows)
• Automatically select and install the appropriate Node.js version to run commands
• Support for running commands with a specified Node.js version
• Support for Node.js version constraints in package.json
• Monorepo project support
• CI/CD environment support
• Compatibility with other Node.js version managers (e.g., nvm, n, fnm)
• Support for opening a new shell session with the nodapt use <version> command

Usage

# Automatically select the appropriate Node.js version to run a command
$ nodapt node -v

# Run a command with a specified Node.js version
$ nodapt use ^18 node -v

# Specify a version range and open a new shell session
$ nodapt use 20

Integrating with Your Node.js Project

1. Add Node.js version constraints to your package.json file:

+  "engines": {
+    "node": "^20.x.x"
+  },
  "scripts": {
    "dev": "vite dev"
  }

2. Use the nodapt command to run scripts:

- yarn dev
+ nodapt yarn dev

Run nodapt --help to see more options.

Installation

Install via Cask (Mac/Linux/Windows)

$ cask install github.com/axetroy/nodapt
$ nodapt --help

Install via npm

$ npm install @axetroy/nodapt -g
$ nodapt --help

Uninstallation

$ nodapt clean # or remove the ~/.nodapt directory
# Then remove the executable file or uninstall it via your package manager

Node.js Version Selection Algorithm

This section explains how nodapt behaves and selects the appropriate Node.js version when executed:

1. Check if a package.json file exists in the current directory.
2. If it exists:
   1. Check if the engines.node field specifies a version constraint:
      • If the currently installed version satisfies the constraint, use it directly.
      • If not, select the latest matching version from the remote list, install it, and then run the command.
   2. If engines.node is not specified, run the command directly.
3. If package.json does not exist, run the command directly.
