我正在尝试开发一个反应同构应用程序，我最近想出了webpack-isomorphic-toolsnpm 包。
我试图按照文档进行操作，但不幸的是图像和样式文件没有被识别，也没有添加到webpack-assets.json文件中。
到目前为止，我一直使用这种方法：
if(process.env.BROWSER){
include('./style.scss');
}
但我知道 webpack-isomorphic-tools 更有益。
对于 scss 和其他样式文件，这是我在运行服务器时遇到的错误：
[webpack-isomorphic-tools] [debug] requiring ./shared/Root.scss
[webpack-isomorphic-tools] [error] asset not found: ./shared/Root.scss
对于图像文件，在构建过程中不会显示错误，因为在构建过程中没有检测到图像。这是webpack-assets.js：
{
"javascript": {
"main": "/build/bundle.js"
},
"styles": {},
"assets": {}
}
相关代码：
webpack-isomorphic-tools-config.js：
var webpack_isomorphic_tools_plugin = require('webpack-isomorphic-tools/plugin');
module.exports =
{
debug: true,
webpack_assets_file_path : 'public/build/webpack-assets.json',
webpack_stats_file_path : 'public/build/webpack-stats.json',
assets:
{
images:
{
extensions: ['png', 'jpg', 'gif', 'ico', 'svg']
},
fonts:
{
extensions: ['woff', 'woff2', 'eot', 'ttf']
},
styles:
{
extensions: ['scss', 'less', 'css'],
filter(module, regular_expression, options, log)
{
if (options.development)
{
// In development mode there's Webpack "style-loader",
// which outputs `module`s with `module.name == asset_path`,
// but those `module`s do not contain CSS text.
//
// The `module`s containing CSS text are
// the ones loaded with Webpack "css-loader".
// (which have kinda weird `module.name`)
//
// Therefore using a non-default `filter` function here.
//
return webpack_isomorphic_tools_plugin.style_loader_filter(module, regular_expression, options, log)
}
// In production mode there will be no CSS text at all
// because all styles will be extracted by Webpack Extract Text Plugin
// into a .css file (as per Webpack configuration).
//
// Therefore in production mode `filter` function always returns non-`true`.
},
// How to correctly transform kinda weird `module.name`
// of the `module` created by Webpack "css-loader"
// into the correct asset path:
path: webpack_isomorphic_tools_plugin.style_loader_path_extractor,
// How to extract these Webpack `module`s' javascript `source` code.
// Basically takes `module.source` and modifies its `module.exports` a little.
parser: webpack_isomorphic_tools_plugin.css_loader_parser
}
}
}
index.js（看起来很像文档中的那个）：
'use strict';
var path = require('path');
require('babel-register');
require('babel-polyfill');
require('app-module-path').addPath(path.join(__dirname,'shared'));
global._development_ = false
if (process.env.NODE_ENV !== 'production'){
global._development_ = true;
}
var Webpack_isomorphic_tools = require('webpack-isomorphic-tools');
// this must be equal to your Webpack configuration "context" parameter
var project_base_path = path.resolve(__dirname);
// this global variable will be used later in express middleware
global.webpack_isomorphic_tools = new Webpack_isomorphic_tools(require('./webpack-isomorphic-tools-config'))
// enter development mode if needed
// (you may also prefer to use a Webpack DefinePlugin variable)
.development(!(process.env.NODE_ENV === 'production'))
// initializes a server-side instance of webpack-isomorphic-tools
// (the first parameter is the base path for your project
// and is equal to the "context" parameter of you Webpack configuration)
// (if you prefer Promises over callbacks
// you can omit the callback parameter
// and then it will return a Promise instead)
.server(project_base_path, function()
{
// webpack-isomorphic-tools is all set now.
// here goes all your web application code:
// (it must reside in a separate *.js file
// in order for the whole thing to work)
require('./server/server')
});
webpack.dev.js（webpack-dev-server 配置）：
var path = require('path');
var webpack = require('webpack');
var Webpack_isomorphic_tools_plugin = require('webpack-isomorphic-tools/plugin')
var webpack_isomorphic_tools_plugin =
// webpack-isomorphic-tools settings reside in a separate .js file
// (because they will be used in the web server code too).
new Webpack_isomorphic_tools_plugin(require('./webpack-isomorphic-tools-config'))
// also enter development mode since it's a development webpack configuration
// (see below for explanation)
.development();
