Fed up with maintaining your bower.json and package.json files with redundant informations ? Then, you're at the good place :-)

What's grunt-bower-npm-unify?

grunt-bower-npm-unify is a Grunt task that populates your bower.json from your package.json. All generic informations (except specific npm ones) specified in your package.json are populated in bower.json.

Installation

# npm install grunt-bower-npm-unify --save-dev

Usage

# grunt bowerNpmUnify

Configuration

Add bowerNpmUnify options in your Gruntfile.js :

For example, here's the default configuration :

grunt.initConfig({
    ...
    bowerNpmUnify: {
        options: {
            npm: 'package.json',
            bower: 'bower.json',
            excludeProperties: [
              'files', 'main', 'bin', 'man', 'directories', 'scripts', 'config',
              'dependencies', 'devDependencies', 'bundledDependencies', 'optionalDependencies',
              'engines', 'engineStrict', 'os', 'cpu', 'preferGlobal', 'publishConfig'
            ],
            dest: 'bower.json'
        }
    },
    ...
});

If your needs match this, you don't have to change your Gruntfile.js The configuration you specify will override the default one.

Example of customization :

grunt.initConfig({
    ...
    bowerNpmUnify: {
        options: {
            npm: 'package.json',
            bower: './lib/bower.json', // custom location
            excludeProperties: [
              'files', 'main', 'bin', 'man', 'directories', 'scripts', 'config',
              'dependencies', 'devDependencies', 'bundledDependencies', 'optionalDependencies',
              'engines', 'engineStrict', 'os', 'cpu', 'preferGlobal', 'publishConfig',
              'version' // added property to exclude
            ],
            dest: './dist/bower.json' // create another file instead of writing into the existing one
        }
    },
    ...
});

Enjoy !
