Nest.JS部署到Heroku

时间：2018-10-16 07:03:42

标签： node.js heroku nestjs

我目前正在尝试部署Nest.JS CLI（从5.3.0版开始）生成的基本启动模板，并且似乎在应用启动时超时。我想知道是否有人设法部署到Heroku？

我不确定是否需要包含某种Procfile？

此外，关于部署Nest.JS似乎没有太多信息

我尝试部署时Heroku会记录日志。

如果有人在部署此堆栈方面有任何经验，很高兴收到您的来信

似乎这里的所有解决方案都适用于以前版本的 Nest。

就我而言（NestJS v7.5.1）启动命令看起来像 "nest start"

在将 "@nestjs/cli" 添加到依赖项后，一切正常。

Heroku默认为您分配一个端口，并将该端口添加到环境变量（env），因此您可以将端口设置为固定编号，需要将主文件更改为：

import { NestFactory } from '@nestjs/core';
import { AppModule } from './app.module';

async function bootstrap() {
  const app = await NestFactory.create(AppModule);
  await app.listen(process.env.PORT || 3000);
}
bootstrap();

答案 2 :(得分：0)

我进行了以下更改以部署新生成的nest.js应用程序：

  1. main.ts-已更改

await app.listen(3000);

到

await app.listen(process.env.PORT || 3000);

  1. 添加了Procfile的内容：web: npm run start:prod

  2. package.json-添加了heroku-postbuild脚本，因此我的脚本看起来像：

  "scripts": {
    "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 nodemon-debug.json",
    "prestart:prod": "rimraf dist && npm run build",
    "start:prod": "node dist/main.js",
    "lint": "tslint -p tsconfig.json -c tslint.json",
    "test": "jest",
    "test:watch": "jest --watch",
    "test:cov": "jest --coverage",
    "test:debug": "node --inspect-brk -r tsconfig-paths/register -r ts-node/register node_modules/.bin/jest --runInBand",
    "test:e2e": "jest --config ./test/jest-e2e.json",
    "heroku-postbuild": "npm install --only=dev --no-shrinkwrap && npm run build"
  },

如果您在Heroku中使用免费套餐，则只能使用 npm start ，而您使用的是 start：prod 。尝试将"start:prod": "node dist/main.js"替换为"start": "node dist/main.js"。

几个小时后……它开始运行了！

1。 package.json（注意：脚本，@ nestjs版本，引擎）

      ".+\\.(t|j)s$": "ts-jest"
    },
    "coverageDirectory": "../coverage",
    "testEnvironment": "node"
  },
  "engines": {
    "node": "8.9.4"
  }
}

2。 Procfile（位置-与package.json相同） 是的，它是没有类型的文件。可以使用记事本创建。

web: npm run start:prod

3。启用安装devDependencies（如果需要） 

heroku config:set NPM_CONFIG_PRODUCTION=false
