    grunt-bower-postinst Build Status

    Execute post install action on bower components

    Some bower components needs additionnal actions once Bower has retrieved the source from the repository. This plugin helps you to automate theses tasks in order to provide you the last step to your client-side dependency manager.

    Getting Started

    This plugin requires Grunt ~0.4.1

    If you haven't used Grunt before, be sure to check out the Grunt 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-bower-postinst --save-dev

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


    The "bower_postinst" task


    In your project's Gruntfile, add a section named bower_postinst to the data object passed into grunt.initConfig().

      bower_postinst: {
            dist: {
                options: {
                    components: {
                        'jquery.ui': ['npm', {'grunt': 'build'}],
                        'bootstrap': ['npm', {'make': 'bootstrap' }]


    Type: String Default value:

    The directory where the bower components are installed. We use by default the current bower configuration.


    Type: String Default value:

        'git submodule' : ['update'],
        'npm' : ['install'],
        'grunt' : [],
        'jake' : [],
        'make' : ['install']

    This options define the default behavior for the predefined commands.


    Type: Object Default value: none


    Type: Array Default value: none

    An array of commands to be executed against the component. The values of the array can be either :

    • a string that match a predefined command ('npm' stands for npm install as in options.actions).
    • an object with the key as a predefined command and the value the additionnals arguments


    The commands for a component are executed in series, in the order defined in options.components.compoenent.

    If there is more than one component then the staks of commands are executed in parrallel by component.

    Usage Example


    In this example, the project needs the following Bower components: jquery, jquery.ui and bootstrap. The components jquery.ui and bootstrap need extra commands to get an aggregated and minimified version of the scripts and stylesheet. We use the task bower from grunt-bower-task to perform the install of the components, then the bower_postinst task from the current plugin to run the required commands.

            clean : ['components'],
            bower : {
                install : {}  
            bower_postinst: {
                dist: {
                    options: {
                        components: {
                            'jquery.ui': ['npm', {'grunt': 'build'}],
                            'bootstrap': ['npm', {'make': 'bootstrap' }]
        //Load the plugin's task.
        grunt.registerTask('install', ['clean', 'bower', 'bower_postinst']);

    These example will execute:

    bower install
    #stack 1 in parallel with stack2 
    cd components/bootstrap
    npm install
    make bootstrap
    cd components/jquery.ui
    npm install
    grunt build


    To help you to resolve your issues, please provide:

    • the versions of node.js, grunt and grunt-bower-postinst
    • the content of your Gruntfile.js
    • the result of the grunt command with the debug option (grunt task --debug) (in a gist)
    • A pull request, if you think something is wrong.


    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 Grunt.
