Dav*_*idL 5 javascript node.js express angular
我正在使用Angular2(客户端)和Node JS(服务器端)技术开始一个新项目.
我已经设法使用node和创建RESTful API express.输入特定URL时,将显示匹配的Json响应.到现在为止还挺好.
现在我正在尝试将Angular 2集成到这个过程中.我已经创建了app.component.显示页面时,组件未加载,我得到了一些404代码:
Failed to load resource: 404 (not found) http://localhost:3000/node_modules/core-js/client/shim.min.js
...
Failed to load resource: 404 (not found) http://localhost:3000/systemjs.config.js
这是我的项目结构:
??? App
| ??? app.component.ts //copied from Angular2/get-started
| ??? main.ts // copied from Angular2/get-started
??? dist //contains generated JS files
??? node_modules
??? server // contains Server Typescript files
??? index.html // copied from Angular2/get-started
??? index.ts // server entry point
??? package.json
??? systemjs.config.js
??? tsconfig.json
??? typings.json
我的package.json:
{
"main": "index.js",
"scripts": {
"start": "tsc && concurrently \"npm run tsc:w\" \"node dist/js/index.js\" ",
"postinstall": "typings install",
"tsc": "tsc",
"tsc:w": "tsc -w",
"typings": "typings"
},
"dependencies": {

},
"devDependencies": {

}
}
我的index.ts(服务器):
var express = require('express');
var app = express();
var path = require('path');
var __projectRoot = __dirname + '/../../';
app.get('/', function (req, res) {
res.sendFile(path.join(__projectRoot + '/index.html'));
});
console.log('Server up and running on http://localhost:3000/');
app.listen(server_port);
总结一下,index.html:
<html>
<head>
<script>document.write('<base href="' + document.location + '" />');</script>
<title>Angular 2 QuickStart</title>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1">
<!-- 1. Load libraries -->
<!-- Polyfill(s) for older browsers -->
<script src="node_modules/core-js/client/shim.min.js"></script>
<script src="node_modules/zone.js/dist/zone.js"></script>
<script src="node_modules/reflect-metadata/Reflect.js"></script>
<script src="node_modules/systemjs/dist/system.src.js"></script>
<!-- 2. Configure SystemJS -->
<script src="systemjs.config.js"></script>
<script>
System.import('app').catch(function (err) {
console.error(err);
});
</script>
</head>
<!-- 3. Display the application -->
<body>
<h1>index.html</h1>
<my-app>Loading...</my-app>
</body>
</html>
加载http:// localhost:3000 /时,我看到"Index.html Loading ...",但不显示该组件.
在Angular2官方网站上,他们使用lite-server依赖.我想我的服务器有问题,但我无法弄清楚如何使它工作.或者有没有办法使用Express和实现RESTful API lite-server？
您忘记添加中间件函数来提供 js 库和 css 等静态文件。之前添加这一行app.get("/", ...)应该可以：
app.use(express.static(__projectRoot));
