Question

我将一个简单的AngularJS应用程序（在本地工作得很好）部署到Heroku中，然后看起来像＆＃34; ng-repeat＆＃34;由于某种原因停止工作，heroku日志没有错误。希望有人能给出一些提示。

项目来源：

在本地运行

npm installn。
node index.js

在heroku上运行：

git clone
heroku create
git add。
git commit -m＆＃34; initial commit＆＃34;
git push heroku master
heroku ps：scale web = 1
heroku open

index.js

＆＃13;

var express = require('express');
var app = express();
var path = require('path');

app.set('port', (process.env.PORT || 5000));

app.use(express.static(__dirname + '/scripts'));
app.use(express.static(__dirname + '/scripts/lib'));
app.use(express.static(__dirname + '/scripts/services'));
app.use(express.static(__dirname + '/scripts/controllers'));

app.get('/',function(req,res){
  res.sendFile(path.join(__dirname+'/index.html'));
  //__dirname : It will resolve to your project folder.
});

app.listen(app.get('port'), function() {
  console.log('Node app is running on port', app.get('port'));
});

我获得了本地和广播输出效果的屏幕截图。 heroku，bud我没有足够的声誉在这里发帖:(

解决

它正在Netify上工作而没有代码更新，我想那可能是heroku env问题，Netify让流程变得更容易 可以从http://json-placeholder-example.netlify.com/

Answer 1

如果ng-repeat在之前和停止工作并且没有错误被抛出，最可能的原因是没有数据被检索。在页面外测试您的数据检索，看看是否是这种情况。

部署到heroku后，ng-repeat无法正常工作
