just-pnpm v1.0.2

just-pnpm

This package utilizes npm package's preinstall and postinstall scrips to restrict that only pnpm package manager could be used on a project.

It's developed as an alternative to npx only-allow pnpm, with some bugs fixed (#15, #2660).

Installation

pnpm add -D just-pnpm

Usage

Add this package to your project's devDependencies and that's it.

If someone executes package installation commands other than pnpm (npm install, yarn, cnpm install, whatever.) on the project, they will get an error instead and installation will not proceed.

{
  "name": "your-project",
  "devDependencies": {
    "just-pnpm": "^1.0.1"
  }
}

For library developers, adding just-pnpm to your package's dependencies will prevent your library from being installed by any package managers except for pnpm. (not recommended though)

Escape Hatches

Set environment variable JUST_PNPM_SKIP_CHECK=true to disable the check temporarily.

Disclaimer

This package relies on NPM lifecycle hooks to work properly.

Although it's tested that the package works on many of popular package managers, a non-standard implementation or misbehavior could possibly break the functionality of package manager restriction.
