将Angular 5 + Nodejs Express应用程序部署到Heroku [英] Deploy Angular 5 + Nodejs Express app to Heroku

问题描述

我有一个Angular 5应用.

I have an Angular 5 App.

这就是我的 package.json

  },
  "engines": {
    "node": "8.9.4",
    "npm": "5.6.0"
  }
}

我创建了一个包含这些内容的 server.js .

constexpress=require('express');
constapp=expres();
constpath=require('path');

app.us(express.static(__dirname+'/dist'));

app.listen(process.env.PORT||8080);


//PathLocationStradegy
app.get('/'function(req,res) {
  res.sendFile(path.join(__dirname+'/dist/index.html'));
});

console.log('Console Listening'); 

---

然后，我运行这些命令

---

Then, I run these commands

heroku auth:login
Email : [e-mail]
Password : #########
heroku create iproject-demo
heroku git:remote iproject-demo
git status
git add -A
git push heroku master

---

调试

我尝试运行此

---

Debug

I tried running this

⚡️web heroku ps

Free dyno hours quota remaining this month: 998h 46m (99%)
For more information on dyno sleeping and how to upgrade, see:
https://devcenter.heroku.com/articles/dyno-sleeping

=== web (Free): npm start (1)
web.1: crashed 2018/01/27 14:18:58 -0500 (~ 1m ago)

---

结果

一切看起来都不错.

Result

everything looks good.

Heroku日志显示构建成功.

但是当我转到应用程序时:

But when I go to the app:

我看到了

如何进一步调试?

推荐答案

这是我使Angular应用程序在Heroku上部署和工作的方式:

Here's how I make my Angular app to deploy and work on Heroku:

1. 您的server.js应该看起来像这样: https://hastebin.com/zavehahide.js
2. 在您的package.json中，将@angular/cli和@angular/compiler-cli从devDependencies移到dependencies
3. 还要在您的package.json中，将postinstall: ng build --prod和start: node server.js添加到scripts

1. Your server.js should look something like this: https://hastebin.com/zavehahide.js
2. In your package.json, move @angular/cli and @angular/compiler-cli from devDependencies to dependencies
3. Also in your package.json, add postinstall: ng build --prod and start: node server.js to scripts

你应该很好.
