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?

I'm currently trying to deploy the basic starter template generated by the Nest.JS CLI (as of version 5.3.0) and seem to be getting a timeout on app startup. I'm wondering if anyone has managed to deploy to Heroku?

我不确定是否需要包含某种Procfile?

I'm not sure whether or not I need to include some kind of Procfile?

此外，关于部署Nest.JS似乎没有太多信息

Also, there doesn't seem to be much info around deploying the Nest.JS

当我尝试部署时，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

If anyone has any experience in deploying this stack it'd be great to hear from you

推荐答案

Heroku默认情况下为您分配一个端口，并将该端口添加到环境变量(env)中，因此您可以将端口设置为固定数字，您需要将您的主文件更改为:

Heroku assigns you a port by default and adds the port to the environment variables (env), so you can set the port to a fixed number, you need to change your main file to:

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();
