我正在使用webpack捆绑我的应用程序,并确保将目标指定为“节点”(否则webpack构建失败)。
使用我当前的配置,构建成功,但是当我尝试使用节点运行它时,出现错误:
C:\ Users \ myuser \ Desktop \ myproject \ dist \ app.js:20 / ****** /
modules [moduleId] .call(module.exports,module,module.exports, webpack_require ); ^TypeError:无法读取未定义的属性“调用”
这是指webpackBootstrap函数内部插入到app.js开头的一行。感觉好像节点与Webpack不兼容,尽管据我所知应该如此。
我怀疑这与问题有关,但为了让您了解完整情况:
我正在编译ts,并将src中的每个文件作为单独的块导出到dist中,而不是将所有内容捆绑在一起,以便在运行时按需动态导入文件。
例如:
将变为:
这是我的webpack.config.js:
const path = require('path');
const CleanWebpackPlugin = require('clean-webpack-plugin');
const { CheckerPlugin } = require('awesome-typescript-loader');
const glob = require('glob');
let entry = {};
glob.sync('./src/**/*.*').forEach(component => {
let name = component.match(/.*\/(.*)\..*/)[1];
entry[name] = component;
});
module.exports = {
mode: 'development',
entry,
target: 'node',
resolve: {
extensions: ['.ts', '.tsx', '.js', '.jsx']
},
devtool: 'inline-source-map',
devServer: {
contentBase: './dist'
},
module: {
rules: [
{
test: /\.tsx?$/,
loader: 'awesome-typescript-loader'
}
]
},
plugins: [
new CleanWebpackPlugin(['dist']),
new CheckerPlugin()
],
output: {
filename: (chunkData) => {
let name = chunkData.chunk.name;
let src = chunkData.chunk.entryModule.id;
let path = src.split('/');
let dir = path[path.length -2];
let pathPrefix = dir !== 'src' ? dir + '/' : '';
return pathPrefix + name + '.js';
},
path: path.resolve(__dirname, 'dist'),
publicPath: '/'
},
optimization: {
splitChunks: {
chunks: 'all'
},
},
};

我需要在配置中包括节点外部。
const path = require('path');
const nodeExternals = require('webpack-node-externals');
module.exports = {
target: "node",
entry: {
app: ["./back.js"]
},
output: {
path: path.resolve(__dirname, "../build"),
filename: "bundle-back.js"
},
externals: [nodeExternals()],
};
