Wire dependencies to your source code.
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>
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.
-
A Bower package may not properly list its
dependencies
in its bower.json file. -
A Bower package may not specify a
main
property 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.
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'));
});
See grunt-wiredep
.
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.
}
Install wiredep globally to wire up Bower packages from the terminal.
$ npm install -g wiredep
$ wiredep
Wire Bower dependencies to your source code.
Usage: $ wiredep [options]
Options:
-h, --help # Print usage information
-v, --version # Print the version
-b, --bowerJson # Path to `bower.json`
-d, --directory # Your Bower directory
-e, --exclude # A path to be excluded
-i, --ignorePath # A path to be ignored
-s, --src # Path to your source file
--dependencies # Include Bower `dependencies`
--devDependencies # Include Bower `devDependencies`
--includeSelf # Include top-level bower.json `main` files
--verbose # Print the results of `wiredep`
You may also take advantage of Bower >=1.3.1's hooks, with a .bowerrc
such as:
{
"scripts": {
"postinstall": "wiredep -s path/to/src.html"
}
}
require('wiredep')({
directory: 'the directory of your Bower packages.', // default: '.bowerrc'.directory || 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.
cwd: 'path/to/where/we/are/pretending/to/be',
dependencies: true, // default: true
devDependencies: true, // default: false
includeSelf: 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.
},
onError: function(err) {
// If not overridden, an error will throw.
// err = Error object.
// err.code can be:
// - "PKG_NOT_INSTALLED" (a Bower package was not found)
// - "BOWER_COMPONENTS_MISSING" (cannot find the `bower_components` directory)
},
onFileUpdated: function(filePath) {
// filePath = 'name-of-file-that-was-updated'
},
onPathInjected: function(fileObject) {
// fileObject.block = 'type-of-wiredep-block' ('js', 'css', etc)
// fileObject.file = 'name-of-file-that-was-updated'
// fileObject.path = 'path-to-file-that-was-injected'
},

// pkg = 'name-of-bower-package-without-main'

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"
}
}
}
In lieu of a formal styleguide, take care to maintain the existing coding style. Add unit tests for any new or changed functionality. Lint and test your code using npm test
.
