npm-only-allow

npm-only-allow

The hook about preinstall of npm behaves inconsistently across package managers.

The existing solution (only-allow) is not working well.

The npm-only-allow goal is to fix them.

Installation

  yarn add npm-only-allow

Usage

Add a postinstall script to your project's package.json.

If you want to force npm|cnpm|pnpm|yarn, add:
(If you want to smooth out the difference, you also need to add it in the startup script)

{
  "scripts": {
    "postinstall": "npm-only-allow --PM yarn --server install",
    "start": "npm-only-allow --server start && vite server or other"
  }
}

params

• PM
