angularjs - 404 Error with simple Express routing -

i trying set routing in node.js app using express.js , mongoose.js using tutorial - https://thinkster.io/mean-stack-tutorial/ when test curl, gives me message:

(the curl script is: curl --data 'title=test&link=http://test.com' http://localhost:3000/#/posts)

error: not found     @ /users/adamz/flapper-news3/app.js:30:13     @ layer.handle [as handle_request] (/users/adamz/flapper-news3/node_modules/express/lib/router/layer.js:82:5)     @ trim_prefix (/users/adamz/flapper-news3/node_modules/express/lib/router/index.js:302:13)     @ /users/adamz/flapper-news3/node_modules/express/lib/router/index.js:270:7     @ function.proto.process_params (/users/adamz/flapper-news3/node_modules/express/lib/router/index.js:321:12)     @ next (/users/adamz/flapper-news3/node_modules/express/lib/router/index.js:261:10)     @ /users/adamz/flapper-news3/node_modules/express/lib/router/index.js:603:15     @ next (/users/adamz/flapper-news3/node_modules/express/lib/router/index.js:246:14)     @ function.proto.handle (/users/adamz/flapper-news3/node_modules/express/lib/router/index.js:166:3)     @ router (/users/adamz/flapper-news3/node_modules/express/lib/router/index. 

for reference app.js file follows:

var express = require('express'); var path = require('path'); var favicon = require('serve-favicon'); var logger = require('morgan'); var cookieparser = require('cookie-parser'); var bodyparser = require('body-parser');  var routes = require('./routes/index'); var users = require('./routes/users');  var mongoose = require('mongoose');  require('./models/posts'); require('./models/comments');  mongoose.connect('mongodb://localhost/news');   var app = express();  // view engine setup app.set('views', path.join(__dirname, 'views')); app.set('view engine', 'ejs');  // uncomment after placing favicon in /public //app.use(favicon(__dirname + '/public/favicon.ico')); app.use(logger('dev')); app.use(bodyparser.json()); app.use(bodyparser.urlencoded({ extended: false })); app.use(cookieparser()); app.use(express.static(path.join(__dirname, 'public')));  app.use('/', routes); app.use('/users', users);  // catch 404 , forward error handler app.use(function(req, res, next) {   var err = new error('not found');   err.status = 404;   next(err); });  // error handlers  // development error handler // print stacktrace if (app.get('env') === 'development') {   app.use(function(err, req, res, next) {     res.status(err.status || 500);     res.render('error', {       message: err.message,       error: err     });   }); }  // production error handler // no stacktraces leaked user app.use(function(err, req, res, next) {   res.status(err.status || 500);   res.render('error', {     message: err.message,     error: {}   }); });   module.exports = app; 

and routes/index.js is:

var express = require('express'); var router = express.router();  var mongoose = require('mongoose'); var post = mongoose.model('post'); var comment = mongoose.model('comment');   /* home page. */ router.get('/', function(req, res, next) {   res.render('index', { title: 'express' }); });  router.get('/posts', function(req, res, next) {   post.find(function(err, posts){     if(err){ return next(err); }      res.json(posts);   }); });   router.post('/posts', function(req, res, next) {   var post = new post(req.body);    post.save(function(err, post){     if(err){ return next(err); }      res.json(post);   }); });  module.exports = router; 

is out of order? copied , pasted directly tutorial, node.js running, mongodb running, i'm not sure what's going on. let me know if other info help. in advance help.

i believe curl script should include quotations around site:

curl --data "title=test&link=http://test.com" "http://localhost:3000/posts"
