How to config `middleware` in connect server

250 views Asked by At

I am using connect server with serve-static for my angular app. according to the stylus doc they ask to use the middleware (https://learnboost.github.io/stylus/docs/middleware.html) to utalize the .styl file. i tried but not working.

In the connect server doc https://github.com/senchalabs/connect#readme shows some way which i am not understand.

here is my code :

var connect = require('connect'),
    serveStatic = require('serve-static');

var app = connect();

app.middleware({
   src: __dirname + '/css',
   dest: __dirname + '/css'
 });

function compile(str, path) {
   return stylus(str)
     .set('filename', 'tcp.styl')
     .set('compress', true)
     .use(nib())
     .import('nib');
 }

app.use(serveStatic("app"));
app.listen(5000, function () {console.log("HI");});

Any one help me to config the mid-ware here?

the error i am getting right now is :

D:\Projects\TCP>node server.js
D:\Projects\TCP\server.js:6
app.middleware({
    ^

update

var connect = require('connect'),
    serveStatic = require('serve-static'),
    stylus = require('stylus');

var app = connect();

app.use(stylus.middleware({
    src     : __dirname + '/app/css',
    dest    : __dirname + '/app/css',
    force   : true,
    compile : function(str, path) {
      return stylus(str, path)
        .set('tcp', path)
        .set('warn', true)
        .set('compress', true);
    }
}));

app.use(serveStatic("app"));
app.listen(5000, function () {console.log("HI", __dirname);});

The Stylus middleware is not shipped anymore by default. https://github.com/senchalabs/connect/blob/0680f226f6bf7cc0c9e21a5a54a83c2deda5c4b4/History.md#057--2011-02-01

You can still use it like

var stylus = require('stylus');

...

app.use(stylus.middleware(...));
