Nest.JS部署到Heroku [英] Nest.JS deploy to Heroku
问题描述
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.

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();
