# Bower - A package manager for the web [![Build](https://github.com/bower/bower/workflows/build/badge.svg)](https://github.com/bower/bower/actions?query=branch%3Amaster) [![Backers on Open Collective](https://opencollective.com/bower/backers/badge.svg)](#backers) [![Sponsors on Open Collective](https://opencollective.com/bower/sponsors/badge.svg)](#sponsors) > ..psst! While Bower is maintained, we recommend [yarn](https://yarnpkg.com/) and [webpack](https://webpack.js.org/) or [parcel](https://parceljs.org/) for new front-end projects!

--- 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.). **View complete docs on [bower.io](http://bower.io)** [View all packages available through Bower's registry](http://bower.io/search/). ## Install ```sh $ npm install -g bower ``` Bower depends on [Node.js](http://nodejs.org/) and [npm](http://npmjs.org/). Also make sure that [git](http://git-scm.com/) is installed as some bower packages require it to be fetched and installed. ## Usage See complete command line reference at [bower.io/docs/api/](http://bower.io/docs/api/) ### Installing packages and dependencies ```sh # install dependencies listed in bower.json $ bower install # install a package and add it to bower.json $ bower install --save # install specific version of a package and add it to bower.json $ bower install # --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](http://gruntjs.com/) or [gulp](http://gulpjs.com/)), and serve them concatenated or using a module loader (like [RequireJS](http://requirejs.org/)). ### Uninstalling packages To uninstall a locally installed package: ```sh $ bower uninstall ``` ### 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` ### Never run Bower with sudo Bower is a user command; there is no need to execute it with superuser permissions. ### Windows users To use Bower on Windows, you must install [Git for Windows](http://git-for-windows.github.io/) correctly. Be sure to check the options 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. ### Ubuntu users To use Bower on Ubuntu, you might need to link `nodejs` executable to `node`: ``` sudo ln -s /usr/bin/nodejs /usr/bin/node ``` ## Configuration Bower can be configured using JSON in a `.bowerrc` file. Read over available options at [bower.io/docs/config](http://bower.io/docs/config). ## Support You can ask questions on following channels in order: * [StackOverflow](http://stackoverflow.com/questions/tagged/bower) * [Issue Tracker](https://github.com/bower/bower/issues) * team@bower.io ## Contributing We welcome [contributions](https://github.com/bower/bower/graphs/contributors) of all kinds from anyone.
