Install npm dependencies based on what version of Node you are using

engine-dependencies

Specify package dependencies based on what version of Node you are using. Useful if you're trying to support Node 0.10.x, 0.12.x and IO.js.

CLI

You can use engine-dependencies within your process as a post-install script. Just define your dependencies in the engineDependencies field of your package.json:

{
	"name": "my-lib",
	"version": "1.0.0",
	"engineDependencies": {
		"node": {
			"0.12.x": {
				"devDependencies": {
					"semver": "^1.0.0"
				}
			}
		},
		"iojs": {
			"^3.0.0": {
				"semver": "2.0.0"
			}
		}
	}
	...
}

And then add to your scripts:

{
	"name": "my-lib",
	"version": "1.0.0",
	"scripts": {
		"postInstall": "install-engine-dependencies my-lib"
	}
	...
}

Node API

engineDependencies({
	"node": {
		"0.10.x": {
			"devDependencies": {
				"jquery": "1.8.0"
			}
		},
		"0.12.x": {
			"jquery": "^1.11.2"
		}
	},
	"iojs": {
		"^3.0.0": {
			"devDependencies": {
				"jquery": "2.1.4"
			}
		}
	}
}, function(err){
	// all done
});

engine-dependencies's Issues

breaks if windows path is lower case like c:\\

Specifying the module name for your package doesn't work.

The issue is that specifying the project name in the post-install script doesn't properly load the package.json for that project.

Not specifying an module name will load the project from the current working directory see code but you never correctly handle the load when the module name is specified.

By the time this code is executed, the findWhere function is trying to call Object.keys on a string, throwing an error. The 'engineDependencies' object is not processed.

My package.json:

{
  "name": "my-test",
  "version": "0.0.0",
  "description": "testing dependency needs",
  "engineDependencies": {
    "node": {
      "4.2.x": {
        "lodash": "4.0.1"
      },
      "0.10.x": {
        "lodash": "3.10.1"
      }
    }
  },
  "dependencies": {
    "async": "*"
  },
  "devDependencies": {
    "grunt": "*"
  },
  "scripts": {
    "postinstall": "install-engine-dependencies 'my-test'"
  }

Executing:

npm install my-test

doesn't install the correct version of lodash because it errors out.

As mentioned above, doing the following will work

"scripts": {
  "postinstall": "./node_modules/engine-dependencies/bin/install-engine-dependencies"
}

due to this block executing.

EDIT: specify "postinstall" instead of "post-install" in package.json
