Jade files, routes folder and server/app.js is not rendering or redirecting

Question

//routes/meal.js
var express = require('express');
var router = express.Router();
var app = express();
/* GET users listing. */
router.get('/meal', function(req, res, next) {
    res.render('/home/noah/Desktop/gadfit/views/meal.jade');

    console.send(req.query + req.body);
    res.json({ 1: 1 });
});

router.patch('/meal', (req, res) => {
    res.send(`PACTH request to / body:${req.body} params: ${req.params[0]}`);

I have a standard and basic app I want to use and make, it loads on the server.js file and I have routes being loaded into it from routes folder and each respective route/x.js folder handles particular request and responses to HTTP protocols. I am trying to divide the code for routing from the actual server app because that is called sanity. It does not load and causes a 404 error when I call a get from say 'localhost:3000/meal' when it should load the respective jade file.

  "name": "gadfit",
  "version": "0.0.0",
  "private": true,
  "scripts": {
    "start": "node ./bin/www"
  },

    "url": "^0.11.0"
  },

I assume this is a coding problem but it could also be an environment/npm problem.

Answer 1

NVM, I had to change the routed name in the respective routes folder to '/' which is kind of cool and makes sense!

var express = require('express');
var router = express.Router();
var app = express();
/* GET users listing. */
router.get('/', function(req, res, next) {
    res.render('/home/noah/Desktop/gadfit/views/meal.jade');
    //res.send('respond with a resource');
});

router.post('/', (req, res) => {
    //res.send('POST request to the homepage');
    //res.redirect('http://google.com')
    console.send(req.query + req.body);
    res.json({ 1: 1 });
});

router.patch('/', (req, res) => {
    res.send(`PACTH request to / body:${req.body} params: ${req.params[0]}`);
});
router.trace('/', (req, res) => {
    res.send('SEND request to /');
});
app.copy('/', (req, res) => {
    res.send('COPY request to /');
});
app.lock('/', (req, res) => {
    res.send('LOCK request to /');
});
app.purge('/', (req, res) => {
    res.send('PURGE request to / ');
});
app.head('/', (req, res) => {
    res.send('HEAD request to /');
});
app.link('/', (req, res) => {
    res.send('LINK request request to / ');
});
app.delete('/', (req, res) => {
    res.send('DELETE request to /');
});
app.options('/', (req, res) => {
    res.send('OPTIONS request to /');
});
app.connect('/', (req, res) => {
    res.send('CONNECT request to /');
});
app.trace('/', (req, res) => {
    res.send('TRACE request to /');
});

module.exports = router;
