Single file bundle with NestJS + Typescript + Webpack + node_modules

Question

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

webpack.config.js

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'),
    },
    extensions: ['.js'],
  },
};

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)

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'),
  },
};

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.

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).
