我的server.js:

// Create our app
var app = express();
const PORT = process.env.PORT || 3000;

app.use(function (req, res, next){
  if (req.headers['x-forwarded-proto'] === 'https') {

});

app.use(express.static('public'));

app.listen(PORT, function () {
  console.log('Express server is up on port ' + PORT);
});

我在heroku上部署了你的应用程序并发现了同样的503错误.然后我在npm run build本地跑,意识到它不起作用.因为redux缺少.它可能对您有用,因为您可以redux在全球范围内安装.

添加后

"redux": "^3.7.2",

到了package.json,并再次推应用程序,它工作得很好,我能够访问应用程序,但它在初始化火力地堡连接,您可以轻松地修复JS错误
