Question

我正在尝试使用angular 5客户端构建快速服务器。我在一个“dev”脚本中一起使用“ts-node”和“nodemon”和“ng build --watch”，因此它们可以自动编译在一起。应用程序每次更改时，nodemon都会说应用程序崩溃了。如果我删除行app.listen，它将每次都有效，没有任何错误。

package.json脚本：

    "dev": "concurrently --kill-others \"nodemon --config ./servernodemon.json\" \"ng build --watch\"",

servernodemon.json：

{
    "delay": "500",
    "ignore": ["servernm/**/*.spec.ts"],
    "verbose": true,
    "exec": "ts-node server/server.app.ts",
    "watch": ["server"],
    "ext": "ts"
}

server.app.ts：

import 'reflect-metadata';
import * as express from 'express';
const path = require('path');

console.log('Revving up server');

const app: express.Express = express();
app.use(express.static(path.join(__dirname, '../dist-site')));

app.get('/*', (req: express.Request, res: express.Response) => {
  res.sendFile(path.join(__dirname, '../dist-site/index.html'));
});

console.log('Starting server');

const port = process.env.PORT || 3005;

app.listen(port, () => {
  console.log(`Server listening on port ${port}!`)
}).on('error', (err) => {
  console.error('Failed to start server', err);
});

3次更改和初次运行后的控制台输出：

$ npm run dev

> project@0.0.0 dev /Users/project
> concurrently --kill-others "nodemon --config ./servernodemon.json" "ng build --watch"

包的版本：

"concurrently": "^3.5.1",
"nodemon": "^1.13.2",
"tslint": "^5.7.0",

带有ts-node express服务器的Nodemon：app崩溃了
