Question

如何？如何捆绑包括node_module的NestJS项目以用于脱机应用程序？

webpack.config.js

const path = require('path');

module.exports = {
  entry: path.join(__dirname, 'dist/main.js'),
  target: 'node',

    path: __dirname,
  },
  resolve: {
    alias: {
      node_modules: path.join(__dirname, 'node_modules'),

或者告诉我一个用于在node.js上开发 windows服务的好框架，该服务具有脚手架，并且内置到单个文件中。（必须将程序集包括所有依赖项，即整个node_modules文件夹，因为要安装此服务的PC 没有Internet 才能使用npm）

Answer 1

@SergeySovgut：我不确定您是否已经设法使用webpack添加自定义配置。但是这是我目前在prj中使用的一个

const nodeExternals = require('webpack-node-externals');
var terserPlugin = require('terser-webpack-plugin');
var uglifyJsPlugin = require('uglifyjs-webpack-plugin');
var dotEnvPlugin = require('dotenv-webpack');

module.exports = function(options) {
    return {
        ...options,
        entry: [ './src/main.ts'],
        watch: false,
        resolve: {
            extensions: ['.ts', '.js', '.jade']
        },
        externals: [
            nodeExternals(),
        ],
        module: {
            rules: [
                ...options.module.rules,
                {
                    test: /\.handlebars$/,
                    loader: 'handlebars-loader',
                    options: {
                        knownHelpersOnly: false,
                        inlineRequires: /\/assets\/(:?images|audio|video)\//ig,
                        partialDirs: [path.join(__dirname, './src/views/email/partials')],
                    },
                }
            ]
        },
        plugins: [
            ...options.plugins,
            new webpack.HotModuleReplacementPlugin(),
            new webpack.WatchIgnorePlugin([/\.js$/, /\.d\.ts$/]),
            new dotEnvPlugin({
                path: './config/development/.env',
                safe: true,
                systemvars: true,
                silent: true,
                defaults: false
            }), new webpack.DefinePlugin({
                'process.env.NODE_ENV': 'dev',
                'process.env.DEBUG': 'debug'
            }),new webpack.WatchIgnorePlugin([/\.js$/, /\.d\.ts$/]),
        ],
    };
};

简而言之，nest附带了webpack。一些规则已预先设置，例如，ts-loader已自动配置为将.ts转换为.js文件。因此，我们所需要做的就是扩展nestjs已经提供的选项，然后在其之上编写我们的自定义配置。

我相信大多数配置都是简单明了的，可以通过webpack文档轻松获得

要运行文件，请配置如下脚本 ->`“ build：webpack：dev”：“ rimraf dist && nest build --watch --webpack webpack.dev.config.js”

然后运行npm run build:webpack:dev

Answer 2

我知道它可以与以下webpack.config.js一起使用：

const path = require("path");
const webpack = require('webpack');
const { CleanWebpackPlugin } = require('clean-webpack-plugin');

const WebPackIgnorePlugin =
{
  checkResource: function(resource)
  {
    const lazyImports =
    [
        '@nestjs/microservices',
        '@nestjs/microservices/microservices-module',
        'cache-manager',
        'class-transformer',
        'class-validator',
        'fastify-static',
    ];
  
    if (!lazyImports.includes(resource))
      return false;

    try
    {
      require.resolve(resource);
    }
    catch (err)
    {
      return true;
    }
  
    return false;
  }
};

module.exports =
{
  mode: 'production',
  target: 'node',
  entry:
  {
    server: './src/main.ts',
  },
  devtool: 'source-map',
  module:
  {
    rules:
    [
      {
        test: /\.tsx?$/,
        use: 'ts-loader',
        exclude: /node_modules/,
      },
    ],
  },
  resolve:
  {
    extensions: [ '.tsx', '.ts', '.js' ],
  },
  node: {
    __dirname: false,
  },
  plugins:
  [
    new CleanWebpackPlugin(),
    new webpack.IgnorePlugin(WebPackIgnorePlugin),
  ],
  optimization:
  {
    minimize: false
  },
  performance:
  {
    maxEntrypointSize: 1000000000,
    maxAssetSize: 1000000000
  },
  output:
  {
    filename: '[name].js',
    path: path.resolve(__dirname, 'prod'),
  },
};

IgnorePlugin是您需要注意的部分。 Nest对某些模块使用延迟加载，而webpack无法分辨出哪个模块。 checkResource()对那些试图捆绑代码时可能会产生错误的模块进行必要的检查。

您还需要在配置中放置target: node选项，以便Webpack知道fs和net之类的某些模块在Node中是本机支持的（当目标服务器不是这种情况时）是浏览器）。

NestJS + Typescript + Webpack + node_modules的单个文件包
