|
| 17 | 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.
|
| 18 |
|
| 19 | 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.).

|
| 22 |
|
| 23 | [View all packages available through Bower's registry](http://bower.io/search/).
|
| 24 |
|
| 25 | ## Install
|
| 26 |
|
| 27 | ```sh
|
| 28 | $ npm install -g bower
|
| 29 | ```
|
| 30 |
|
| 31 | 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
|
| 32 | packages require it to be fetched and installed.
|
| 33 |
|
| 34 |
|
| 35 | ## Usage
|
| 36 |
|
| 37 | See complete command line reference at [bower.io/docs/api/](http://bower.io/docs/api/)
|
| 38 |
|
| 39 | ### Installing packages and dependencies
|
| 40 |
|
| 41 | ```sh
|
| 42 | # install dependencies listed in bower.json
|
| 43 | $ bower install
|
| 44 |
|
| 45 | # install a package and add it to bower.json
|
| 46 | $ bower install <package> --save
|
| 47 |
|
| 48 | # install specific version of a package and add it to bower.json
|
| 49 | $ bower install <package>#<version> --save
|
| 50 | ```
|
| 51 |
|
| 52 | ### Using packages
|
| 53 |
|
| 54 | 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).
|
| 55 |
|
| 56 | 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/)).
|
| 57 |
|
| 58 | ### Uninstalling packages
|
| 59 |
|
| 60 | To uninstall a locally installed package:
|
| 61 |
|
| 62 | ```sh
|
| 63 | $ bower uninstall <package-name>
|
| 64 | ```
|
| 65 |
|
| 66 | ### prezto and oh-my-zsh users
|
| 67 |
|
| 68 | On `prezto` or `oh-my-zsh`, do not forget to `alias bower='noglob bower'` or `bower install jquery\#1.9.1`
|
| 69 |
|
| 70 | ### Never run Bower with sudo
|
| 71 |
|
| 72 | Bower is a user command; there is no need to execute it with superuser permissions.
|
| 73 |
|
| 74 | ### Windows users
|
| 75 |
|
| 76 | To use Bower on Windows, you must install
|
| 77 | [Git for Windows](http://git-for-windows.github.io/) correctly. Be sure to check the
|
| 78 | options shown below:
|
| 79 |
|
| 80 | <img src="https://cloud.githubusercontent.com/assets/10702007/10532690/d2e8991a-7386-11e5-9a57-613c7f92e84e.png" width="534" height="418" alt="Git for Windows" />
|
| 81 |
|
| 82 | <img src="https://cloud.githubusercontent.com/assets/10702007/10532694/dbe8857a-7386-11e5-9bd0-367e97644403.png" width="534" height="418" alt="Git for Windows" />
|
| 83 |
|
| 84 | Note that if you use TortoiseGit and if Bower keeps asking for your SSH
|
| 85 | password, you should add the following environment variable: `GIT_SSH -
|
| 86 | C:\Program Files\TortoiseGit\bin\TortoisePlink.exe`. Adjust the `TortoisePlink`
|
| 87 | path if needed.
|
| 88 |
|
| 89 | ### Ubuntu users
|
| 90 |
|
| 91 | To use Bower on Ubuntu, you might need to link `nodejs` executable to `node`:
|
| 92 |
|
| 93 | ```
|
| 94 | sudo ln -s /usr/bin/nodejs /usr/bin/node
|
| 95 | ```
|
| 96 |
|
| 97 | ## Configuration
|
| 98 |
|
| 99 | Bower can be configured using JSON in a `.bowerrc` file. Read over available options at [bower.io/docs/config](http://bower.io/docs/config).
