    Nest.JS部署到Heroku

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

    我不确定我是否需要包含某种Procfile？

    此外，似乎没有太多关于部署Nest.JS的信息

    当我尝试部署时，Heroku会记录。

    如果有人有部署这个堆栈的经验，那么很高兴收到你的来信

    回答如下：

    Heroku默认为您指定一个端口并将端口添加到环境变量（env），因此您可以将端口设置为固定数字，您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();

    我不确定我是否需要包含某种Procfile？
