I'm trying to add a new route in my express app but I keep getting error when trying to start the server. The error is
C:\development\node\express_app\node_modules\express\lib\router\index.js:252
throw new Error(msg);
^
Error: .get() requires callback functions but got a [object Undefined]
here are my files, I'm new to node so let me know if i left out an important file
routes/furniture.js
exports.furniture = function(req, res){
res.render('furniture', { title: '4\267pli' });
};
routes/index.js
/*
* GET home page.
*/
exports.index = function(req, res){
res.render('index', { title: '4\267pli' });
};

The express. Router() function is used to create a new router object. This function is used when you want to create a new router object in your program to handle requests. Multiple requests can be easily differentiated with the help of the Router() function in Express. js.
A route is a section of Express code that associates an HTTP verb ( GET , POST , PUT , DELETE , etc.), a URL path/pattern, and a function that is called to handle that pattern. There are several ways to create routes.
Answer: A is the correct option. By using app. route() method, we can create chainable route handlers for a route path in Express.
The trouble is:
routes = require('./routes'),
user = require('./routes/user'),
furniture = require('./routes/furniture'),
These 3 are setting your routes folders, not a specific file, express will look for a index.js ( not found, then --> error)
Inside these folders, you should put a index.js with your:
exports.xxxx = function(req, res){
res.render('xx', { foo: foo});
};
Then, your project folder structure should look like:
routes/
├── index.js
│
├── user/
│ └── index.js (with a exports.user inside)
│
└── fourniture/
└── index.js (with a exports.furniture inside)
You can add multiple export functions to a route like these:
app.js
// a folder called routes with the index.js file inside
routes = require('./routes')
.
.
.
app.get('/', routes.main_function);
app.get('/sec_route', routes.sec_function);
app.post('/other_route', routes.other_function);
/routes/index.js
exports.main_function = function(req, res){
res.render('template1', { foo: foo });
};
exports.sec_function = function(req, res){
res.render('template2', { bar: bar });
};
exports.other_function = function(req, res){
res.render('template1', { baz: baz });
};
