如何在pm2中使用tsconfig路径？

Question

我正在尝试用pm2部署我的类型记录项目，但是这个论点似乎不正确。

以下是ecosystem.config.yml：

apps:
  - name: 'node-app'
    script: './src/main.ts'
    interpreter: './node_modules/.bin/ts-node'
    # they dont't work correctly below.
    interpreter_args: '-r tsconfig-paths/register'
    # args: '-T -r tsconfig-paths/register ./src/index.ts',
    # args: '-r ./node_modules/tsconfig-paths/register ./src/main.ts'
    # interpreter_args: ['--require=tsconfig-paths/register']
    # interpreter_args: '-P . -r ./node_modules/tsconfig-paths/register'
    kill_timeout: 10000
    instances: max
    exec_mode: cluster
    env:
      NODE_ENV: development

当我运行pm2时，启动ecosystem.config.yml并检查日志：

0|node-app | Error: Cannot find module '~framework/common/frame-util'
0|node-app |     at Function.Module._resolveFilename (internal/modules/cjs/loader.js:581:15)
0|node-app |     at Function.Module._load (internal/modules/cjs/loader.js:507:25)

0|node-app |     at Module._extensions..js (internal/modules/cjs/loader.js:700:10)

0|node-app |     at Module.load (internal/modules/cjs/loader.js:599:32)

我的tsconfig.json是：

{
  "compilerOptions": {
    "module": "commonjs",
    "declaration": true,
    "removeComments": true,
    "emitDecoratorMetadata": true,
    "experimentalDecorators": true,
    "target": "es2017",
    "sourceMap": true,
    "outDir": "./dist",
    "baseUrl": "./",
    "incremental": true,
    "rootDir": ".",
    "paths": {
      "~framework/*":["src/framework/*"],
      "~solution/*":["src/solution/*"],
      "~business/*":["src/solution/business/*"],
      "~dto/*":["src/solution/dto/*"],
      "~entities/*":["src/solution/entities/*"],
      "~/*":["src/*"]
    }
  },
  "exclude": ["node_modules", "dist"]
}

路径别名似乎不能正常工作。它在没有pm2的情况下运行良好(这是一个nestjs项目)：

...
    "start": "rimraf dist && cross-env NODE_ENV=development ts-node -r tsconfig-paths/register src/main.ts",
...

有人能帮我解决这个问题吗？谢谢。

正如Aleksandr所说，您可以首先使用tsc构建项目，然后使用node而不是ts-node运行它。

示例：

1. 在脚本运行程序(在package.json中)中，可以定义：

  "build": "tsc",
  "runBuild": "pm2 start ecosystem.yml --only node-app"

1. 在您的ecosystem.yml中，可以定义：

apps:
  - name: 'node-app'
    script: './dist/src/main.js'
    node_args: '-r ts-node/register -r tsconfig-paths/register'
    kill_timeout: 10000
    instances: max
    exec_mode: cluster
    env:
      NODE_ENV: development

1. 跑：

$ npm run build
$ npm run runBuild

希望这有帮助
