问题描述

怎么样?如何捆绑 NestJS 项目，包括用于离线应用的 node_module?

How? How I can bundle NestJS project including node_module for offline application?

const path = require('path');

module.exports = {
  entry: path.join(__dirname, 'dist/main.js'),
  target: 'node',
  output: {
    filename: 'compiled.js',
    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 的好的框架，它具有脚手架并且构建到单个文件中.(程序集必须包含所有依赖项，即整个 node_modules 文件夹，因为将安装此服务的 PC 没有 Internet 以使用 npm)

Or tell me a good framework for developing windows service on node.js which has scaffold and builds into a single file. (it is imperative that the assembly includes all dependencies, that is, the entire node_modules folder, because the PCs to which this service will be installed does not have Internet for using npm)

推荐答案

我让它与以下 webpack.config.js 一起工作:

I got it to work with the following webpack.config.js:

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'),
  },
};

这里需要注意的部分是IgnorePlugin.Nest 对某些模块使用了延迟加载，而 webpack 无法分辨哪些模块.checkResource() 对那些在尝试捆绑代码时可能会产生错误的模块进行必要的检查.

The part you need to pay attention to here is the IgnorePlugin. Nest uses lazy loading for some modules, and webpack can't tell which ones. The checkResource() makes the necessary checks for those modules that eould otherwise generate errors when trying to bundle your code.

您还需要将 target: node 选项放在您的配置中，以便 webpack 知道某些模块如 fs 和 net 是本机支持的在 Node 中(当目标是浏览器时不是这种情况).

You also need to put the target: node option in your config so that webpack knows some modules like fs and net are supported natively in Node (which is not the case when the target is a browser).
