如何将 NestJs 数据库模型项目导入另一个项目？

Question

我需要在多个 NestJs 项目中导入一个包含所有数据库实体 classes 的 NestJs 项目，以减少代码重复。

这是我的数据库实体项目package.json

  "version": "1.0.0",
  "main": "dist/index.js",
  "files": [
    "dist/**/*",

    "ts-node": "9.0.0",
    "tsconfig-paths": "^3.9.0",
    "typescript": "^3.7.4"
  },
  "jest": {
    "moduleFileExtensions": [
      "js",
      "json",
      "ts"
    ],
    "rootDir": "src",
    "testRegex": ".spec.ts$",
    "transform": {
      "^.+\.(t|j)s$": "ts-jest"
    },
    "coverageDirectory": "../coverage",
    "testEnvironment": "node"
  }
}

我在另一个项目中导入包运行 npm install PATH_TO_ENTITIES_PACKAGE 但是当我尝试声明一个实体时 class 我的 IDE 不建议从我的本地包导入，如果我手动导入它，我无法从我的导入语句导航到 class 本身。

有没有我遗漏的信息？

Answer 1

Nestjs 默认支持 monorepo 概念，您可以在不同项目之间共享代码。

您可以在 doc

中阅读更多相关信息

Answer 2

除了 monorepo 建议之外，您还可以实施 microservice 架构。
