将 angular-universal 应用程序部署到 heroku

Question

我一直在尝试将我的 angular-universal start 应用程序部署到 heroku。我已经设置了一些我通常使用角度节点应用程序所做的事情，但为此我可能做错了什么。

这是我遇到的错误

2017-12-18T07:16:23.453463+00:00 heroku[web.1]: Error R10 (Boot timeout) -> Web process failed to bind to $PORT within 60 seconds of launch

但我是动态设置 PORT。

这是我的文件夹结构

我认为我的设置可能有问题。 包.json

var app = require('../server');
var debug = require('debug')('test:server');
var http = require('http');

var port = normalizePort(process.env.PORT || '3000');
app.set('port', port);

var server = http.createServer(app);

//models.sequelize.sync({alter: true}).then(function() {
  server.listen(port, function() {
    console.log('Express server listening on port ' + server.address().port);
    });
  server.on('error', onError);
  server.on('listening', onListening);
//});




function normalizePort(val) {
  var port = parseInt(val, 10);

  if (isNaN(port)) {
    // named pipe
    return val;
  }

  if (port >= 0) {
    // port number
    return port;
  }

  return false;
}

function onError(error) {
  if (error.syscall !== 'listen') {
    throw error;
  }

  var bind = typeof port === 'string'
    ? 'Pipe ' + port
    : 'Port ' + port;

  // handle specific listen errors with friendly messages
  switch (error.code) {
    case 'EACCES':
      console.error(bind + ' requires elevated privileges');
      process.exit(1);
      break;
    case 'EADDRINUSE':
      console.error(bind + ' is already in use');
      process.exit(1);
      break;
    default:
      throw error;
  }
}


function onListening() {
  var addr = server.address();
  var bind = typeof addr === 'string'
    ? 'pipe ' + addr
    : 'port ' + addr.port;
  debug('Listening on ' + bind);
}

还有 server.ts

import 'zone.js/dist/zone-node';
import 'reflect-metadata';
import { renderModuleFactory } from '@angular/platform-server';
import { enableProdMode } from '@angular/core';

import * as express from 'express';
import { join } from 'path';
import { readFileSync } from 'fs';
import * as cookieParser from 'cookie-parser';
import * as bodyParser from "body-parser";
import * as logger from 'morgan';

// Faster server renders w/ Prod mode (dev mode never needed)
enableProdMode();

// Express server
const app = express();

const DIST_FOLDER = join(process.cwd(), 'dist');

// Our index.html we'll use as our template
const template = readFileSync(join(DIST_FOLDER, 'browser', 'index.html')).toString();

// * NOTE :: leave this as require() since this file is built Dynamically from webpack
const { AppServerModuleNgFactory, LAZY_MODULE_MAP } = require('./dist/server/main.bundle');

// Express Engine
import { ngExpressEngine } from '@nguniversal/express-engine';
// Import module map for lazy loading
import { provideModuleMap } from '@nguniversal/module-map-ngfactory-loader';

// Our Universal express-engine (found @ https://github.com/angular/universal/tree/master/modules/express-engine)
app.engine('html', ngExpressEngine({
  bootstrap: AppServerModuleNgFactory,
  providers: [
    provideModuleMap(LAZY_MODULE_MAP)
  ]
}));

app.set('view engine', 'html');
app.set('views', join(DIST_FOLDER, 'browser'));

app.use(logger('dev'));

app.use(bodyParser.json({limit: '50mb'}));
app.use(bodyParser.urlencoded({extended: true}, {limit: '50mb'}));
app.use(cookieParser());

/* - Example Express Rest API endpoints -
  app.get('/api/**', (req, res) => { });
*/

// Server static files from /browser
app.get('*.*', express.static(join(DIST_FOLDER, 'browser'), {
  maxAge: '1y'
}));

// ALl regular routes use the Universal engine
app.get('*', (req, res) => {
  res.render('index', { req });
});


module.exports = app;

除了 bin 设置之外，我还使用了 repo 开始的所有内容。不知道我必须做什么才能将其部署在 heroku 上

Answer 1

我看到您正在使用 Universal Starter 存储库。我采用了相同的存储库并对其进行了一些调整，以使其与 Heroku 一起使用没问题。

我记录了这些更改 on Medium 并发布了编辑后的 ​​repo on GitHub

我希望其中任何一个对我有帮助 - 我一直在运行我的 Universal 应用程序，现在没有问题
