wiredep

Wire dependencies to your source code.

Getting Started

Install the module with npm:

$ npm install --save wiredep

Install your bower dependencies (if you haven't already):

$ bower install --save jquery

Insert placeholders in your code where your dependencies will be injected:

<html>
<head>
  <!-- bower:css -->
  <!-- endbower -->
</head>
<body>
  <!-- bower:js -->
  <!-- endbower -->
</body>
</html>

Let wiredep work its magic:

$ node
> require('wiredep')({ src: 'index.html' });

index.html modified.
{ packages:
   { jquery:
      { main: [Object],
        type: [Object],
        name: 'jquery',
        dependencies: {} } },
  js: [ 'bower_components/jquery/dist/jquery.js' ] }
<html>
<head>
  <!-- bower:css -->
  <!-- endbower -->
</head>
<body>
  <!-- bower:js -->
  <script src="bower_components/jquery/dist/jquery.js"></script>
  <!-- endbower -->
</body>
</html>

Build Chain Integration

gulp.js

wiredep works with streams and integrates with gulp.js out of the box:

var wiredep = require('wiredep').stream;

gulp.task('bower', function () {
  gulp.src('./src/footer.html')
    .pipe(wiredep({
      optional: 'configuration',
      goes: 'here'
    }))
    .pipe(gulp.dest('./dest'));
});

Grunt

See grunt-bower-install.

Programmatic Access

You can run wiredep without manipulating any files.

require('wiredep')();

...returns...

{
  js: [
    'paths/to/your/js/files.js',
    'in/their/order/of/dependency.js'
  ],
  css: [
    'paths/to/your/css/files.css'
  ],
  // etc.
}

Configuration

require('wiredep')({
  directory: 'the directory of your Bower packages.', // default: 'bower_components'
  bowerJson: 'your bower.json file contents.',        // default: require('./bower.json')
  src: ['filepaths', 'and/even/globs/*.html' 'to take', 'control of.'],

  // ----- Advanced Configuration -----
  // All of the below settings are for advanced configuration, to
  // give your project support for additional file types and more
  // control.
  //
  // Out of the box, wiredep will handle HTML files just fine for
  // JavaScript and CSS injection.

  dependencies: true,    // default: true
  devDependencies: true, // default: false

  exclude: [ /jquery/, 'bower_components/modernizr/modernizr.js' ],

  ignorePath: /string or regexp to ignore from the injected filepath/,
  
  overrides: {
    // see `Bower Overrides` section below.
    //
    // This inline object offers another way to define your overrides if
    // modifying your project's `bower.json` isn't an option.
  },

  fileTypes: {
    fileExtension: {
      block: /match the beginning-to-end of a bower block in this type of file/,
      detect: {
        typeOfBowerFile: /match the way this type of file is included/
      },
      replace: {
        typeOfBowerFile: '<format for this {{filePath}} to be injected>'
      }
    },

    // defaults:

        css: /-\s(.+)/gi

      replace: {
        js: '- {{filePath}}'
        css: '- {{filePath}}'
      }
    }
  }
});

Bower Overrides

To override a property, or lack of, in one of your dependency's bower.json file, you may specify an overrides object in your own bower.json.

As an example, this is what your bower.json may look like if you wanted to override package-without-main's main file:

{
  ...
  "dependencies": {
    "package-without-main": "1.0.0"
  },
  "overrides": {
    "package-without-main": {
      "main": "dist/package-without-main.js"
    }
  }
}
