    A package manager for the web

    Bower offers a generic, unopinionated solution to the problem of front-end package management, while exposing the package dependency model via an API that can be consumed by a more opinionated build stack. There are no system wide dependencies, no dependencies are shared between different apps, and the dependency tree is flat.

    Bower runs over Git, and is package-agnostic. A packaged component can be made up of any type of asset, and use any type of transport (e.g., AMD, CommonJS, etc.).

    $ npm install -g bower

    Bower depends on Node.js and npm. Also make sure that git is installed as some bower packages require it to be fetched and installed.

    Installing packages and dependencies

    # install dependencies listed in bower.json 
    $ bower install
    # install a package and add it to bower.json 
    $ bower install <package> --save
    # install specific version of a package and add it to bower.json 
    $ bower install <package>#<version> --save

    Using packages

    We discourage using bower components statically for performance and security reasons (if component has an upload.php file that is not ignored, that can be easily exploited to do malicious stuff).

    The best approach is to process components installed by bower with build tool (like Grunt or gulp), and serve them concatenated or using module loader (like RequireJS).

    Uninstalling packages

    To uninstall a locally installed package:

    $ bower uninstall <package-name>

    prezto and oh-my-zsh users

    On prezto or oh-my-zsh, do not forget to alias bower='noglob bower' or bower install jquery\#1.9.1

    Running commands with sudo

    Bower is a user command, there is no need to execute it with superuser permissions. However, if you still want to run commands with sudo, use --allow-root option.

    Windows users

    To use Bower on Windows, you must install msysgit correctly. Be sure to check the option shown below:


    Note that if you use TortoiseGit and if Bower keeps asking for your SSH password, you should add the following environment variable: GIT_SSH - C:\Program Files\TortoiseGit\bin\TortoisePlink.exe. Adjust the TortoisePlink path if needed.


    Bower can be configured using JSON in a .bowerrc file. Read over available options at

    Completion (experimental)

    NOTE: Completion is still not implemented for the 1.0.0 release

    Bower now has an experimental completion command that is based on, and works similarly to the npm completion. It is not available for Windows users.

    This command will output a Bash / ZSH script to put into your ~/.bashrc, ~/.bash_profile, or ~/.zshrc file.

    $ bower completion >> ~/.bash_profile


    Bower can collect anonymous usage statistics. This allows the community to improve Bower and publicly display insights into CLI usage and packages at

    Data is tracked using Google Analytics and instrumented via Insight. It is made available to all bower team members. Tracking is opt-in upon initial usage. If you'd prefer to disable analytics altogether, you can manually opt-out, or create either a local, or global .bowerrc file with:

      "analytics": false
