Logger不是Node.js中的函数错误

Question

As in my previous questions I said, I am trying to create an HTTP server, testing some middlewares codes, but in my code right now is giving basically the same error from another times, but I can't see where I am getting this wrong.

My code :

logger.js

var http = require('http');
var connect = require('connect');
var app = connect();
// setup logger middleware
app.use(connect.logger());
// actually respond
app.use(function(req, res) {
res.end('Hello World!');
});
http.createServer(app).listen(8080);

He points out to the connect.logger() even if I am using app.use() , still gives me this error.

connect.logger is not a function

Answer 1

Connect no longer comes with a built-in logger! Try using some logging library like morgan

var http = require('http');
var connect = require('connect');
var logger = require('morgan');

var app = connect();
// setup logger middleware
app.use(logger("combined")); //Without one string in logger() it will give deprecated morgan format, so it needs to use some string for work, the documentation it say so.

// actually respond
app.use(function(req, res) {
   res.end('Hello World!');
});
http.createServer(app).listen(8080)
