如何使用Node.js自动编译.coffeescript？

Question

我喜欢在CoffeeScript中编写我的堆栈，我只是想知道如何在运行时使用Node.js自动编译它，所以我不必手动编译每个咖啡文件，然后编辑并将.js移动到该文件，这是我现在（只是为了测试）;

---

/routes/index.coffee: 

---

exports.index = (req, res) -> 
    res.render "index", 
    title: "Express" 

---

app.js: 

---

/** 
* Module dependencies. 
*/ 
require('coffee-script'); 
var express = require('express') 
    , staticp = require('./routes/index') 
    , user = require('./routes/user') 
    , http = require('http') 
    , path = require('path'); 

var app = express(); 

// all environments 
app.set('port', process.env.PORT || 3000); 
app.set('views', __dirname + '/views'); 
app.set('view engine', 'jade'); 
app.use(express.favicon()); 
app.use(express.logger('dev')); 
app.use(express.bodyParser()); 
app.use(express.methodOverride()); 
app.use(app.router); 
app.use(express.static(path.join(__dirname, 'public'))); 

// development only 
if ('development' == app.get('env')) { 
    app.use(express.errorHandler()); 
} 

app.get('/', staticp.index); 
app.get('/users', user.list); 

http.createServer(app).listen(app.get('port'), function(){ 
    console.log('Express server listening on port ' + app.get('port')); 
});

Answer 1

只是require('coffee-script');提前。

更新： 如果您使用CoffeeScript> = 1.7.0，则需要register()它。

Answer 2

您可以开始coffee -wc *.coffee，它们将在保存时重新编译.coffee文件。
