通过结构化的Express应用程序提供html和javascript
我目前正在玩Express，并试图解决（我相信应该是）一个微不足道的问题。
我有以下的目录结构：
|-config |---config.js |---routes.js |-server.js |-scripts |---controllers |------controllers.js |---directives |---filters |---services |---templates |---app.js |-views |---index.html 我的server.js
var express = require('express'); var app = express(); require('./config/config.js')(app); require('./config/routes.js')(app); app.listen(7777);
我的config.js
module.exports = function(app){ app.set('views', __dirname + '../views'); app.engine('html', require('ejs').renderFile); }
我的routes.js
module.exports = function(app, express){ app.get('/', function(reg, res){ res.render('index.html') }) app.use(function(err, req, res, next){ console.error(err.stack); res.send(500, 'Something broke!'); }); }
最后我的index.html
<html lang="en"> <head> <title></title> <script type='text/javascript' src='http://ajax.googleapis.com/ajax/libs/angularjs/1.1.5/angular.min.js'> </script> </head> <body> Hello World!!! </body> </html>
当我访问本地主机：7000 /
我明白了
Error: Failed to lookup view "index.html" at Function.app.render (/Users/abe/github/leap-motion-signature-recognition/node_modules/express/lib/application.js:494:17) at ServerResponse.res.render (/Users/abe/github/leap-motion-signature-recognition/node_modules/express/lib/response.js:756:7) at /Users/abe/github/leap-motion-signature-recognition/config/routes.js:7:13 at callbacks (/Users/abe/github/leap-motion-signature-recognition/node_modules/express/lib/router/index.js:161:37) at param (/Users/abe/github/leap-motion-signature-recognition/node_modules/express/lib/router/index.js:135:11) at pass (/Users/abe/github/leap-motion-signature-recognition/node_modules/express/lib/router/index.js:142:5) at Router._dispatch (/Users/abe/github/leap-motion-signature-recognition/node_modules/express/lib/router/index.js:170:5) at Object.router (/Users/abe/github/leap-motion-signature-recognition/node_modules/express/lib/router/index.js:33:10) at next (/Users/abe/github/leap-motion-signature-recognition/node_modules/express/node_modules/connect/lib/proto.js:190:15) at Object.expressInit [as handle] (/Users/abe/github/leap-motion-signature-recognition/node_modules/express/lib/middleware.js:30:5)
这是为什么？ __dirName set不应该挂钩views\index.html ？
其次，我打算使用这个服务器来支持一个Angular JS应用程序与许多JavaScript文件。 Rails资产pipe道的快速答案是什么？ 我怎样才能毫不费力地包含整个目录，没有明确的script标记，并且尽可能地缩短部署时间？
__dirname没有结尾斜杠，所以你应该把__dirname + '../views'改为__dirname + '/../views' 。
您可以使用静态中间件从目录中提供静态文件：
app.use(express.static(__dirname + '/scripts'));
express-uglify可以缩小你的JavaScript文件：
var expressUglify = require('express-uglify'); app.use(expressUglify.middleware({ src: __dirname + '/scripts' }));
