如何将精简服务器替换为我的快速服务器.js适用于 Angular 2

Question

好吧，这个问题可能与 Angular 2 无关，但是......在观看了Deborah的PluralSight Getting Start视频后，我尝试将现有的angular 1.x项目迁移到angular 2。对于客户端部分，我想切换到 TypeScript 和 Angular 2，但对于服务器部分，我想尽可能保留现有代码。我遇到的第一个问题是如何将Deborah项目中使用的lite-server替换为我自己的服务器.js，同时保持她的浏览器同步设置。这是她的package.json文件的一部分，该文件使用带有-c参数的lite-server：

"scripts": {
    "build": "tsc -p src/",
    "build:watch": "tsc -p src/ -w",
    "serve": "lite-server -c=bs-config.json",
    "prestart": "npm run build",
    "start": "concurrently "npm run build:watch" "npm run serve"",
    "lint": "tslint ./src/**/*.ts -t verbose"
},

bs-config.json看起来像这样：

{
  "server": {
    "baseDir": "src",
    "routes": {
      "/node_modules": "node_modules"
    }
  }
}

我的问题是如何用我的服务器替换精简服务器.js看起来像这样：

var express  = require('express');
var app      = express(); 
var morgan = require('morgan');
var bodyParser = require('body-parser');
var http = require('http');
var path = require('path');
var session = require('express-session');
var route = require('./server/route');
app.use(express.static(__dirname + '/public'));    
app.use(bodyParser.json({ type: 'application/vnd.api+json' }));
var port = 3000;
app.listen(port);
console.log('App listening on port ' + port);
route.init(app);
app.get('*', function(req, res) {
   res.sendfile(__dirname + '/public/index.html');
});

systemjs.config.js

/**
 * System configuration for Angular 2 samples
 * Adjust as necessary for your application needs.
 */
(function (global) {
  System.config({
    paths: {
      // paths serve as alias
      'npm:': 'node_modules/'
    },
    // map tells the System loader where to look for things
    map: {
      // our app is within the app folder
      app: 'app',
      // angular bundles
      '@angular/core': 'npm:@angular/core/bundles/core.umd.js',
      '@angular/common': 'npm:@angular/common/bundles/common.umd.js',
      '@angular/compiler': 'npm:@angular/compiler/bundles/compiler.umd.js',
      '@angular/platform-browser': 'npm:@angular/platform-browser/bundles/platform-browser.umd.js',
      '@angular/platform-browser-dynamic': 'npm:@angular/platform-browser-dynamic/bundles/platform-browser-dynamic.umd.js',
      '@angular/http': 'npm:@angular/http/bundles/http.umd.js',
      '@angular/router': 'npm:@angular/router/bundles/router.umd.js',
      '@angular/forms': 'npm:@angular/forms/bundles/forms.umd.js',
      // other libraries
      'rxjs': 'npm:rxjs'
    },
    // packages tells the System loader how to load when no filename and/or no extension
    packages: {
      app: {
        main: './main.js',
        defaultExtension: 'js'
      },
      rxjs: {
        defaultExtension: 'js'
      }
    }
  });
})(this);

tsconfig.json

{
  "compilerOptions": {
    "target": "es5",
    "module": "commonjs",
    "moduleResolution": "node",
    "sourceMap": true,
    "emitDecoratorMetadata": true,
    "experimentalDecorators": true,
    "lib": [ "es2015", "dom" ],
    "noImplicitAny": true,
    "suppressImplicitAnyIndexErrors": true
  }
}

Answer 1

您可以使用类似reload for express的东西

reloadServer = reload(server, app);
watch.watchTree(__dirname + "/public", function (f, curr, prev) {
    // Fire server-side reload event
    reloadServer.reload();
});

它适用于Nodemoon，Forever和Node-Supervisor，这是使用Reload的推荐方式。

Answer 2

Update Package.json.再次运行 npm 安装。然后 npm 开始。

"scripts": {
"start": "node server/server.js"
}

"服务器/服务器.js"是服务器.js文件的路径。
