我有一个Angular 5应用。
这是我在package.json中拥有的东西。

我创建了一个 server.js 文件,并添加了以下内容。
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
heroku auth:login
Email : johndoe@outlook.com
Password : #########
heroku create iproject-demo
heroku git:remote iproject-demo
git status
git add -A
git push heroku master
调试
我尝试运行这个程序
⚡️ web heroku ps

结果
一切看起来都很好。

我该如何进一步调试?
ng build
之后,你需要让express将所有的HTTP调用重定向回index.html,这样Angular才能接管。 - Mike Tung
