Grunt-deps-ok NPM

grunt-deps-ok

Quickly checks if top level dependencies are missing or out of date using deps-ok

Getting Started and Install

This plugin requires Grunt ~0.4.1

If you haven't used Grunt before, be sure to check out the Getting Started guide, as it explains how to create a Gruntfile as well as install and use Grunt plugins. Once you're familiar with that process, you may install this plugin with this command:

npm install grunt-deps-ok --save-dev

Configuration

Once the plugin has been installed, it may be enabled inside your Gruntfile with this line of JavaScript:

grunt.loadNpmTasks('grunt-deps-ok');
grunt.registerTask('default', ['deps-ok', rest of the tasks]);

That's it! Every time grunt runs, it will quickly check if all (normal, dev, peer) top level dependencies are present in the node_modules folder. It will also verify that the installed module versions are greater or equal to the ones declared inside package.json file.

You can configure further by providing options

// Gruntfile.js
'deps-ok': {
  options: {
    verbose: true,
    force: true // print error message, but pass the task
    skipBower: false, // do not check bower.json even if exists
    folder: 'path/to/folder/with/package.json' // options, by default current folder
  }
}

There are other modules that check npm dependencies, for example grunt-check-modules. It seems to rely on npm ls command that takes a long time to go through the dependency tree. In my projects, deps_ok step takes less than 100ms, compared to 5-10 seconds for grunt-check-modules.
