webpack - require('node_modules/leaflet/leaflet.css')

所以我正在尝试使用构建一个地图应用程序webpack and leaflet。我可以要求leaflet.js从我的map.js文件，但我无法在不出现错误的情况下调用 leaflet.css 。

我现在的webpack.config.js好像：

'use strict'

var webpack = require('webpack'),
    path = require('path'),
    HtmlWebpackPlugin = require('html-webpack-plugin'),
    srcPath = path.join(__dirname, 'src');

module.exports = {
    target: "web",
    cache: true,
    entry: {
        app: path.join(srcPath, "index.js")
    },
    resolve: {
        alais: {
            leaflet_css: __dirname + "/node_modules/leaflet/dist/leaflet.css"
        }
    },
    module: {
        loaders: [
          {test: /\.js?$/, exclude: /node_modules/, loader: "babel-loader"},
          {test: /\.scss?$/, exclude: /node_modules/, loader: "style!css!sass!"},
          {test: /\.css?$/, loader: "style!css!"}
        ]
    },
    plugins: [
        new webpack.optimize.CommonsChunkPlugin("common", "common.js"),
        new HtmlWebpackPlugin({
          inject: true,
          template: "src/index.html"
        }),
        new webpack.NoErrorsPlugin()
      ],
    output: {
        path: path.join(__dirname, "dist"),
        publicPath: "/dist/",
        filename: "[name].js",
        pathInfo: true
    }
}

And my main.js文件看起来像：

var $ = require('jquery'),
    leaflet = require('leaflet');

require("./sass/main.scss");
require("leaflet_css");

var map = L.map('map').setView([51.505, -0.09], 13);

L.tileLayer('http://{s}.tile.osm.org/{z}/{x}/{y}.png', {
    attribution: '&copy; <a href="http://osm.org/copyright">OpenStreetMap</a> contributors'
}).addTo(map);

L.marker([51.5, -0.09]).addTo(map)
    .bindPopup('A pretty CSS3 popup.<br> Easily customizable.')
    .openPopup();

console.log('I got called');

通过 webpack 捆绑来自 3rd 方供应商的 css 文件的正确方法是什么？

I saw 这个项目 https://github.com/Summer-Top/single-page-react-webpack were leaflet存储在libs目录中...这是什么原因，为什么存储在libs目录，如果它安装到node_modules目录通过npm?

这在很大程度上是一个学习练习，因此非常感谢任何指点！ :)

事实证明，答案是webpack的resolve.alias和文件加载器的组合。我的新 webpack 文件如下所示：

'use strict'

var webpack = require('webpack'),
    path = require('path'),
    HtmlWebpackPlugin = require('html-webpack-plugin'),
    srcPath = path.join(__dirname, 'src');

module.exports = {
    target: "web",
    cache: true,
    entry: {
        app: path.join(srcPath, "index.js")
    },
    resolve: {
        extensions: ['', '.html', '.js', '.json', '.scss', '.css'],
        alias: {
            leaflet_css: __dirname + "/node_modules/leaflet/dist/leaflet.css",
            leaflet_marker: __dirname + "/node_modules/leaflet/dist/images/marker-icon.png",
            leaflet_marker_2x: __dirname + "/node_modules/leaflet/dist/images/marker-icon-2x.png",
            leaflet_marker_shadow: __dirname + "/node_modules/leaflet/dist/images/marker-shadow.png"
        }
    },
    module: {
        loaders: [
          {test: /\.js?$/, exclude: /node_modules/, loader: "babel-loader"},
          {test: /\.scss?$/, exclude: /node_modules/, loader: "style-loader!css-loader!sass-loader!"},
          {test: /\.css?$/, loader: "style-loader!css-loader!"},
          {test: /\.(png|jpg)$/, loader: "file-loader?name=images/[name].[ext]"}
        ]
    },
    plugins: [
        new webpack.optimize.CommonsChunkPlugin("common", "common.js"),
        new HtmlWebpackPlugin({
          inject: true,
          template: "src/index.html"
        }),
        new webpack.NoErrorsPlugin()
      ],
    output: {
        path: path.join(__dirname, "dist"),
        publicPath: "/dist/",
        filename: "[name].js",
        pathInfo: true
    }
}

然后我需要做的就是需要 .js 文件中的图标

require("./sass/main");
require("leaflet_css");
require("leaflet_marker");
require("leaflet_marker_2x");
require("leaflet_marker_shadow");

迷人的！！！ :)
