wiredep 
Wire Bower dependencies to your source code.
Getting Started
Install the module with npm:
$ npm install --save wiredepInstall your dependencies (if you haven't already):
$ bower install --save jqueryInsert 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>How it Works
Installing a Bower package with --save will add the package as a dependency in your project's bower.json file. This library reads that file, then reads the bower.json files for each of those dependencies. Based on these connections, it determines the order your scripts must be included before injecting them between placeholders in your source code.
What can go wrong?
A Bower package may not properly list its
dependenciesin its bower.json file.A Bower package may not specify a
mainproperty in its bower.json file.
In both of these cases, it is most helpful to send a PR to the offending repository with a solution. This isn't just a fix for wiredep, but for other tools which conform to the Bower specification. Most often it's just an author's oversight, so they will welcome the contribution and clarity.
If that solution doesn't work, you can get around these problems by overriding properties.
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-wiredep.
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.
}Command Line
** wiredep-cli has been split into its own module. In a future release it will not be included in this package anymore **
Install wiredep-cli to use the CLI.
$ npm install -g wiredep-cliConfiguration
require('wiredep')({
directory: 'the directory of your Bower packages.', // default: '.bowerrc'.directory || bower_components
bowerJson: 'your bower.json file contents.', // default: require('./bower.json')

// ----- 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.

},

}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 (the path is relative to your dependency's folder):
{
...
"dependencies": {
"package-without-main": "1.0.0"
},
"overrides": {
"package-without-main": {
"main": "dist/package-without-main.js"
}
}
}If the project has multiple files, such as a javascript and a css file, main can be an array, as such:
{
...
"dependencies": {
"package-without-main": "1.0.0"
},
"overrides": {
"package-without-main": {
"main": ["dist/package-without-main.css", "dist/package-without-main.js"]
}
}
