peerdep

A warning system for peer dependencies.

peerDependencies may become removed from npm but that doesn't mean modules won't have peer dependencies. Any time a module accepts a plugin a peer dependency has been created. This library will help you warn users when they have not installed a compatible peer dependency.

NPM

usage

Install with npm install peerdep --save and then in your module/plugin's package.json, define your peerDependencies as normal but include this peerdep install script:

{
  "name": "my-plugin",
  "version": "0.1.0",
  "scripts": {
    "install": "peerdep"
  },
  "peerDependencies": {
    "grunt": "~0.4.1"
  },
  "dependencies": {
    "peerdep": "~0.1.0"
  }
}

Now when your plugin has been installed it will run the peerdep script to check if a compatible version of grunt@~0.4.1 has been installed. If it has not been installed or an incompatible version has been installed peerdep will log a warning to the user upon npm install:

WARN peerinvalid Peer my-plugin@0.1.0 wants grunt@~0.4.1 but found "grunt@0.3.0" installed.

Alternative peerDependencies key

The first argument of the peerdep script is an alternate key if you want to avoid conflicts with the existing peerDependencies key:

{
  "name": "my-plugin",
  "version": "0.1.0",
  "scripts": {
    "install": "peerdep myPeerDependencies"
  },
  "myPeerDependencies": {
    "grunt": "~0.4.1"
  },
  "dependencies": {
    "peerdep": "~0.1.0"
  }
}
