style loader for webpack
Usage
Simple API
require("style!raw!./file.css");
// => add rules in file.css to document
It's recommended to combine it with the css-loader: require("style!css!./file.css").
It also possible to add a URL instead of a css string:
require("style/url!file!./file.css");
// => add a <link rel="stylesheet"> to file.css to document
Placeholders
(experimental)
When using placeholders (see css-loader) the module exports the placeholders object:
var styles = require("style!css!./file.css");
style.placeholder1 === "z849f98ca812bc0d099a43e0f90184"
Reference-counted API
var style = require("style/useable!css!./file.css");
style.use(); // = style.ref();
style.unuse(); // = style.unref();
Styles are not added on require, but instead on call to use/ref. Styles are removed from page if unuse/unref is called exactly as often as use/ref.
Note: Behavior is undefined when unuse/unref is called more often than use/ref. Don't do that.
Options
insertAt
By default, the style-loader appends <style> elements to the end of the <head> tag of the page. This will cause CSS created by the loader to take priority over CSS already present in the document head. To insert style elements at the beginning of the head, set this query parameter to 'bottom', e.g. require('../style.css?insertAt=bottom').
singleton
If defined, the style-loader will re-use a single <style> element, instead of adding/removing individual elements for each required module. Note: this option is on by default in IE9, which has strict limitations on the # of style tags allowed on a page. You can enable or disable it with the singleton query parameter (?singleton or ?-singleton).
Recommended configuration
By convention the reference-counted API should be bound to .useable.css and the simple API to .css (similar to other file types, i. e. .useable.less and .less).
So the recommended configuration for webpack is:
{
module: {
loaders: [
{ test: /\.css$/, exclude: /\.useable\.css$/, loader: "style!css" },
{ test: /\.useable\.css$/, loader: "style/useable!css" }
]
}
}
Install
npm install style-loader
