Afternest build或nest build --webpackdist 文件夹不包含所有必需的模块，我Error: Cannot find module '@nestjs/core'在尝试运行node main.js.

我在https://docs.nestjs.com/上找不到任何关于如何正确构建生产应用程序的明确说明，所以也许我错过了什么？

所以,我正在使用typeORM,当我将TypeScript转换为JavaScript时,我遇到了一个奇怪的错误.我收到以下错误:

(function (exports, require, module, __filename, __dirname) { import { Entity, PrimaryGeneratedColumn, ManyToOne, OneToMany, TreeChildren, TreeParent, JoinColumn, Column, Tree, TreeLevelColumn } from "typeorm";
                                                              ^^^^^^

我的tsconfig.json:

{
    "compilerOptions": {
        "lib": [
           "es5",
           "es6"

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

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'],
  },
};

包.json

{
  "name": "kai-brs",
  "version": "0.9.1",
  "author": "Sovgut Sergey",
  "private": true,
  "scripts": {
    "build:webpack": "rimraf dist && tsc -p tsconfig.build.json && webpack dist/main.js -o dist/main.bundle.js --mode=production",
    "build": "tsc -p tsconfig.build.json",
    "format": "prettier --write \"src/**/*.ts\"",
    "start": "ts-node -r tsconfig-paths/register src/main.ts",
    "start:dev": "nodemon",
    "start:debug": "nodemon --config …

我有一个 Nestjs 应用程序，我需要将它与 webpack 捆绑在一起。捆绑包应包含整个脚本和所有文件。所以我创建了我的 webpack 配置：

const webpack = require('webpack');
const path = require('path');

module.exports = {
  entry: {
    backend: './src/index.ts',
  },
  target: 'node',
  module: {
    rules: [
      {
        test: /.ts$/,
        use: 'ts-loader',
      },
      {
        test: /\.(graphql|gql)$/,
        exclude: /node_modules/,
        loader: 'webpack-graphql-loader',
      },
      {
        test: /\.mjs$/,
        include: /node_modules/,
        type: "javascript/auto",
      }
    ],
  },
  externals: ['fsevents'],
  mode: 'production',
  resolve: {
    extensions: ['.ts', '.mjs', '.js', '.json'],
  },
  output: {
    path: path.join(__dirname, 'bundled'),
    library: 'handler',
    libraryTarget: "commonjs2"
  },
  plugins: [
    new webpack.IgnorePlugin({
      checkResource(resource) …

I have set up a pretty plain project with express, node.js and webpack. After installing TypeORM when configuring webpack.config.js it triggers unexpected token error for User.ts in entity folder.

The problem seems to be related to the fact that ormconfig.json is referring to .ts entity files.

Solution in similar threads seems to be using ts-node with some extra parameters, but I am using webpack in this project and executing the bundle file.

index.ts

import 'reflect-metadata';
import { createConnection } from …
