pnpm single version

Enforce Single version of dependencies on pnpm workspace.

Installation

pnpm add -D pnpm-single-version

Usage

Add following options to package.json in project root

"pnpmSingleVersion": {
    "includes": [
        // Place all the single version dependencies here
        "@babel/core",
        "esbuild",
        // glob is also supported
        "eslint-plugin-*",
        "*-plugin",
    ]
}

Maunal Checking using CLI

You can pnpm-single-version in Terminal

pnpm pnpm-single-version

or

pnpm psv

Automatic resolve (Recommanded)

Apart from manual checking, checking can also be done when pnpm-lock.yaml is resolved, where pnpm detected dependencies changes running pnpm install , pnpm update and pnpm removed. This is much effective.

By using afterAllResolved hook in .pnpmfile.cjs, installation process can be interrupted when non-single version dependencies is detected.

To setup it up,

1. First, install checker via

   pnpm pnpm-single-version install

   this command will generate a checker file inside .psv directory of the root directory of workspace.

2. Then you should create a .pnpmfile.cjs and add following code

   const hook = require('./.psv/hook')
      
   module.exports = {
       hooks: {
           afterAllResolved: hook
       }
   }

Now, when you call pnpm install and pnpm update, checking is going to be involve automatically only when have dependenices changes.

PS: You may need to run psv install every time you update pnpm-single-version
