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.).

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
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).
To uninstall a locally installed package:
$ bower uninstall <package-name>
prezto and oh-my-zsh users
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
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
path if needed.
Bower can be configured using JSON in a
.bowerrc file. Read over available options at bower.io/docs/config.
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
$ 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 stats.bower.io.
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
