Nodapt (/noʊˈdæpt/) is a command-line tool that adapts to multiple NodeJS versions. It will run commands with the appropriate NodeJS version based on the NodeJS version constraints in packages.json.

When developing NodeJS projects, we often need to switch NodeJS versions. For example, project A requires 16.x.y, while project B uses 20.x.y.

However, global version management tools like nvm cannot meet the requirements. It has the following problems:

1. nvm is not cross-platform, and it is not very convenient to use on Windows.
2. nvm needs to install the specified version in advance to switch, which is not very friendly to the CI/CD environment.
3. In a Monorepo, there may be a situation where package A requires 16.x.y, while package B requires 20.x.y. In this case, nvm cannot solve this problem well.

So I developed this tool to solve this problem.

It will run the command with the appropriate NodeJS version according to the NodeJS version constraint in packages.json.

# Automatically select the NodeJS version to run the command
$ nodapt node -v

# Specify the NodeJS version and run the specified command
$ nodapt use ^18 node -v

1. Add NodeJS version constraint in package.json.

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

2. Run the script with nodapt command.

- yarn dev
+ nodapt yarn dev

1. Install via Cask (Mac/Linux/Windows)

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

2. Install via npm

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

$ nodapt clean
# then remove the binary file or uninstall via package manager

This section explains what happens when you run nodapt and how it selects the node version.

1. Check for the presence of package.json.
2. If package.json exists:
   1. If the engines.node field is specified, use the indicated version.
      1. If the currently installed version matches engines.node, the command is run using the currently installed version.
      2. Otherwise, select the latest matching version from the remote list, install it, and run the command.
   2. Otherwise, run the command directly.
3. Otherwise, run the command directly.
