How to define the routes? - node.js

Question

I am new to NodeJs and Express. I want to make an Ajax call from an ejs file :
<script>
$(document).ready(function() {
$.ajax({
async : false,
url: "/organisation/list",
success : function(data, status, xhr) {
alert("finsihed");
}
});
});
</script>
Here is the config of my app :
var createError = require('http-errors');
var express = require('express');
var path = require('path');
var cookieParser = require('cookie-parser');
var logger = require('morgan');
var indexRouter = require('./routes/index');
var app = express();
// view engine setup
app.set('views', path.join(__dirname, 'views'));
app.set('view engine', 'ejs');
app.use(logger('dev'));
app.use(express.json());
app.use(express.urlencoded({ extended: false }));
app.use(cookieParser());
app.use(express.static(path.join(__dirname, 'public')));
app.use('/', indexRouter);
// catch 404 and forward to error handler
app.use(function(req, res, next) {
next(createError(404));
});
// error handler
app.use(function(err, req, res, next) {
// set locals, only providing error in development
res.locals.message = err.message;
res.locals.error = req.app.get('env') === 'development' ? err : {};
// render the error page
res.status(err.status || 500);
res.render('error');
});
module.exports = app;
Here is the index.js file :
var express = require('express');
var router = express.Router();
/* GET home page. */
router.get('/', function(req, res, next) {
res.render('index', { title: 'Express' });
});
module.exports = router;
How to make it possible to reach the Ajax url /organisation/list ? Should I create another file in the routes directory ?

Answer 1

You can simply write a route like this :
var express = require('express');
var router = express.Router();
/* GET home page. */
router.get('/', function(req, res, next) {
res.render('index', { title: 'Express' });
});
/* GET organisation list. */
router.get('/organisation/list', function(req, res, next) {
res.render('index', { title: 'Express' });
});
module.exports = router;
or you can create a separate file that handles all requests related to the organization.
app.js
app.use('/organization', require('./routes/organization.js');
routes/organization.js
var express = require('express');
var router = express.Router();
/* GET home page. */
router.get('/list', function(req, res, next) {
//res.render('index', { title: 'Express' });
res.status(200).json([]);
});
module.exports = router;
