system-npm

This is a plugin for StealJS that makes it easy to work with npm.

The idea is to reduce the amount of manual configuring needed when using StealJS and instead leverage the metadata included in package.json to have the configuration done for you.

Install

If you're using StealJS you don't have have to install this plugin, it's included by default.

Configuration

All of the configuration happens within the system property of your package.json.

main

The moduleName of the initial module that should be loaded when the package is imported. This works similar to a System.map setting. For example:

{
  "name": "my-module",
  "version": "1.2.3",
  "system": {
    "main": "my-main"
  }
}

When "my-module" is imported, my-module@1.2.3#my-main will be the actual module name being imported. This path that my-main will be found depends on the directories.lib setting.

meta

The meta config works similar to the base System.meta behavior. However, the module names must:

• Start with ./ to add metadata to modules within the package like "./src/util", or
• Look like packageName#./modulePath to add metadata to direct dependencies of the package.

Example:

{
  "system": {
    "meta": {
      "./src/utils": {"format": "amd"},
      "jquery": {"format": "global"},
      "lodash#./array/grep": {"format": "es6"}
    }
  }
}

npmIgnore

Use npmIgnore to prevent package information from being loaded for specified dependencies or the peerDependencies, devDependencies, or dependencies. The following ignores a package.json's devDependencies and cssify. But all other dependencies will be loaded:

{
  "dependencies": {
    "canjs": "2.1.0",
    "cssify": "^0.6.0"
  },
  "devDependencies": {
    "steal-tools": "0.5.0"
  },
  "system": {
    "npmIgnore": ["devDependencies","cssify"]
  }
}

The following packages are ignored by default:

• "steal", "steal-tools"
• "bower"
• "grunt", "grunt-cli"

npmDependencies

Like npmIgnore but affirmative. If used alone will only include the dependencies listed. If used in conjunction with npmIgnore acts as an override. For example the following config:

{
  "dependencies": {
    "one": "1.0.0",
	"two": "1.0.0"
  },
  "system": {
    "npmDependencies": [ "one" ]
  }
}

Will load one but ignore two.

ignoreBrowser

Set to true to ignore browserfy's "browser" and "browserify" configurations.

{
  "system": {
    "ignoreBrowser": true
  }
}

directories

Set a folder to look for module's within your project. Only the lib directory can be specified.

In the following setup, "my-project/my-utils" will be looked for in my-project/src/my-utils.js:

{
  "name": "my-project"
  "system": {
    "directories" : {
      "lib" : "src"
    }
  }
}
