Javascript-after connect is referenced in node, errors will always be reported when the built-in middleware is used.

{Code ...} tip: connect. cookieParserisnotafunction; when bodyParser is used, it will also prompt that it is said that it has been removed from connect on the internet. if it is necessary to restart the npminstallcookieParser, will bodyParser be required? is all built-in middleware required?

    var connect = require('connect');    var app = connect()        .use(connect.cookieParser())        .use(function(req,res){        console.log(req.cookie);        console.log(req.signedCookies);    }).listen(3000);

Tip: connect. cookieParser is not a function;
When bodyParser is used, a message is displayed,
The internet says it was disconnected from connect. we need to re-install npm cookieParser,
So does bodyParser need it, and all built-in middleware needs it?

CookieParser and other middleware have been removed from connect and can be used independently without loading connect.

Next, why are there no parameters?
