我有一个目录结构
projectName
| - bower_components/
| - public/
| - css
| - js
| - index.html
| - Gruntfile.js
| - package.json
| - bower.json
| - app.js
我想启动我的应用程序并提供服务index.html与节点。所以在app.js I have:
var express = require('express');
var port = process.env.PORT || 3000;
var app = express();
app.configure(function(){
// Serve up content from public directory
app.use(express.static(__dirname + '/public'));
app.use(app.router);
app.use(express.logger());
});
app.listen(port, function(){
console.log('Express server listening on port ' + port);
});
在底部index.html I have:
<script src="../bower_components/jquery/jquery.js"></script>
<script src="../bower_components/d3/d3.js"></script>
<script src="../bower_components/bootstrap/dist/js/bootstrap.js"></script>
<script src="bower_components/spin.js/spin.js"></script>
<script src="bower_components/mustache/mustache.js"></script>
当我启动服务器时，index.html显示但以上库均未加载。我收到错误（404）：
GET http://localhost:3000/bower_components/jquery/jquery.js 404 (Not Found) localhost/:32
GET http://localhost:3000/bower_components/d3/d3.js 404 (Not Found) localhost/:33
GET http://localhost:3000/bower_components/bootstrap/dist/js/bootstrap.js 404 (Not Found) localhost/:34
GET http://localhost:3000/bower_components/spin.js/spin.js 404 (Not Found) localhost/:35
GET http://localhost:3000/bower_components/mustache/mustache.js 404 (Not Found)
如何从 Bower_components 提供文件？
我使用这个设置：
app.use(express.static(__dirname + '/public'));
app.use('/bower_components', express.static(__dirname + '/bower_components'));
所以任何 Bower 组件都是从 HTML 加载的，如下所示：
<script src="/bower_components/..."></script>
以及任何其他客户端 JS/CSS（在public/) 的加载方式如下：
<script src="/js/..."></script>
