所以我一直在尝试设置React Js环境。我面临babel依赖错误。我将css导入到服务器端渲染react项目中,出现了
之类的问题模块构建失败(来自../ node_modules / babel-loader / lib / index.js):
错误:找不到相对于目录的预设“ react-app” 而且我无法添加代理,如果我添加代理的操作不正确
这是我的webpack代码:
const dev = process.env.NODE_ENV !== "production";
const path = require( "path" );
const { BundleAnalyzerPlugin } = require( "webpack-bundle-analyzer" );
const FriendlyErrorsWebpackPlugin = require( "friendly-errors-webpack-plugin" );
const plugins = [
new FriendlyErrorsWebpackPlugin(),
];
if ( !dev ) {
plugins.push( new BundleAnalyzerPlugin( {
analyzerMode: "static",
reportFilename: "webpack-report.html",
openAnalyzer: false,
} ) );
}
module.exports = {
mode: dev ? "development" : "production",
context: path.join( __dirname, "src" ),
devtool: dev ? "none" : "source-map",
entry: {
app: "./client.js",
},
resolve: {
modules: [
path.resolve( "./src" ),
"node_modules",
],
},
module: {
rules: [
{
test: [/\.svg$/, /\.gif$/, /\.jpe?g$/, /\.png$/],
loader: "file-loader",
options: {
name: "public/media/[name].[ext]",
publicPath: url => url.replace(/public/, ""),
emit: false
}
},
{
test: /\.css$/,
use: [
{
loader: "css-loader/locals"
}
]
},
{
test: /jsx?$/,
exclude: /(node_modules)/,
loader: "babel-loader",
query: { presets: ["react-app"] }
}
]
},
output: {
path: path.resolve( __dirname, "dist" ),
filename: "[name].bundle.js",
},
plugins,
};
这是我的通天塔
