鉴于下面的 Webpack 构建,我如何集成 CSS-Modules(Webpack 配置下方链接中的 Web 包的链接和示例)。
// For info about this file refer to webpack and webpack-hot-middleware documentation
// Rather than having hard coded webpack.config.js for each environment, this
// file generates a webpack config for the environment passed to the getConfig method.
import webpack from 'webpack';
import path from 'path';
import ExtractTextPlugin from 'extract-text-webpack-plugin';
const developmentEnvironment = 'development' ;
const productionEnvironment = 'production';
const testEnvironment = 'test';
const getPlugins = function (env) {
const GLOBALS = {
'process.env.NODE_ENV': JSON.stringify(env),
__DEV__: env === developmentEnvironment
};
const plugins = [
new webpack.optimize.OccurenceOrderPlugin(),
new webpack.DefinePlugin(GLOBALS) //Tells React to build in prod mode. https://facebook.github.io/react/downloads.html
];
switch (env) {
case productionEnvironment:
plugins.push(new ExtractTextPlugin('styles.css'));
plugins.push(new webpack.optimize.DedupePlugin());
plugins.push(new webpack.optimize.UglifyJsPlugin());
break;
case developmentEnvironment:
plugins.push(new webpack.HotModuleReplacementPlugin());
plugins.push(new webpack.NoErrorsPlugin());
break;
}
return plugins;
};
const getEntry = function (env) {
const entry = [];
if (env === developmentEnvironment ) { // only want hot reloading when in dev.
entry.push('webpack-hot-middleware/client');
}
entry.push('./src/index');
return entry;
};
const getLoaders = function (env) {
const loaders = [{ test: /\.js$/, include: path.join(__dirname, 'src'), loaders: ['babel', 'eslint'] }];
if (env === productionEnvironment ) {
// generate separate physical stylesheet for production build using ExtractTextPlugin. This provides separate caching and avoids a flash of unstyled content on load.
loaders.push({test: /(\.css|\.scss)$/, loader: ExtractTextPlugin.extract("css?sourceMap!sass?sourceMap")});
} else {
loaders.push({test: /(\.css|\.scss)$/, loaders: ['style', 'css?sourceMap', 'sass?sourceMap']});
}
return loaders;
};
function getConfig(env) {
return {
debug: true,
devtool: env === productionEnvironment ? 'source-map' : 'cheap-module-eval-source-map', // more info:https://webpack.github.io/docs/build-performance.html#sourcemaps and https://webpack.github.io/docs/configuration.html#devtool
noInfo: true, // set to false to see a list of every file being bundled.
entry: getEntry(env),
target: env === testEnvironment ? 'node' : 'web', // necessary per https://webpack.github.io/docs/testing.html#compile-and-test
output: {
path: __dirname + '/dist', // Note: Physical files are only output by the production build task `npm run build`.
publicPath: '',
filename: 'bundle.js'
},
plugins: getPlugins(env),
module: {
loaders: getLoaders(env)
}
};
}
export default getConfig;
这是 CSS 模块的链接 https://github.com/css-modules/webpack-demo
这是一个例子:

{
test: /\.css$/,
loader: 'style!css-loader?modules&importLoaders=1&localIdentName=[name]__[local]___[hash:base64:5]'
}
