Bower.io is a popular repository of client-side JavaScript libraries.
To use it in your meteor application, create a bower.json
file:
{
"name": "my-app",
"version": "0.0.1",
"dependencies": {
"select2": "3.4.5",
"backbone": "1.1.0"
},
"private": true
}
If you want to use a bower library at script load time (outside of a
Meteor.startup
block, template handler, event, etc), you have to place the
bower.json
file so that it loads first (see [Meteor load
order](http://stackoverflow.com/questions/10693113/how-do-i-change-the-order-in-
which-meteor-loads-javascript-files)). Take the deepest directory you have
inside [project root]/lib/
, add a bower
directory, and put bower.json
there. So for example, if you currently have no directories in lib/
, then you
can do lib/bower/bower.json
, but if your current structure is lib/foo/bar/
,
then you should do lib/foo/bar/bower/bower.json
.
The next time you run meteor
, the select2
and backbone
libraries will be
downloaded, and the appropriate HTML tags to include those libraries will
automatically be added to your app. So you can just start using select2
widgets, and styles will be set correctly. (If you're curious just look at the
HTML source of a rendered page!) We use the main
section of the library's
bower.json
file to determine which files should be loaded.
If the package
you're adding doesn't use the main
section: you can choose which files you
want by adding an override
field to your bower.json
as described in
#54.
Compare this to just using the bower
command, where you need to either manually
reference the included files or use something like
grunt-bower-install
to reference them.
If you want to use the bower install <package> --save
command, you can add
this .bowerrc
file in the project root directory:
{
"directory": ".meteor/local/bower"
}
If you need to reference the raw files (eg Polymer components in html files),
you can set a different directory, eg "public/bower_components", and include those files
manually in your <head>
.
Make modernizr
only available on the client by setting the arch
in your bower.json
:
"overrides": {
"modernizr": {
"arch": [ "client" ]
}
}
Other values include [ "server" ]
and [ "client", "server" ]
.
You can ask meteor-bower
to ignore a list of dependencies. For instance if you
have the Meteor package reactjs:react
and the bower package react-bootstrap
,
and you don't want meteor-bower
to include a duplicate copy of react, add an
ignoredDependencies
array to your bower.json
:
{
"name": "my-app",
"version": "0.0.1",
"dependencies": {
"select2": "3.4.5",
"react-bootstrap": "~0.16.1"
},
"ignoredDependencies": [
"react"
]
}
You can also have multiple
bower.json
files, each paired with a .bowerrc
, for instance:
bower.json:
{
"dependencies": {
"select2": "3.4.5"
}
...
}
.bowerrc
{
"directory": ".meteor/local/bower"
}
lib/bower.json:
{
"dependencies": {
"polymer": "~0.5.1"
}
...
}
lib/.bowerrc:
{
"directory": "../public/bower_components"
}
