I have a route.js which looks like this:
module.exports = function(app) {
app.get('/tip', function(req, res) {
res.render("tip");
});
app.get('/article', function(req, res) {
res.render("article");
});
app.get('/article1', function(req, res) {
res.render("article1");
});
app.get('/article2', function(req, res) {
res.render("article2");
});
app.get('/article3', function(req, res) {
res.render("article3");
});
app.get('/modules/:name', function(req, res) {
var name = req.params.name;
res.render('modules/' + name);
});
app.get('/modules/esaver/:name', function(req, res) {
var name = req.params.name;
res.render('modules/esaver/' + name);
});
};
Considering i have over 200 different routes to create, i would end up with stuff like 'article1', 'article2' etc
and my app.js is like:
var express = require('express')
,http = require('http')
,fs = require('fs')
,path = require('path');
var app = express();
html_templates = __dirname + '/html_templates';
app.set('views', html_templates + '/views');
app.set('view engine', 'jade');
app.use('/Core', express.static(__dirname + '/Core'));
app.listen(3000, function () {
console.log("express has started on port 3000");
});
require('./html_templates/controller/routes.js')(app);
Is there any dynamic way to create this?
I would do the same thing you did for /modules/:name
app.get('/article/:id', function(req , res){
res.render('article' + req.params.id);
});
It would be more meaningful from a rest point of view.
If you cannot do it for any particular reason you might want to do something like:
var articlesEndpoints = ['/article2', '/article3'];
articlesEndpoints.forEach(function(name) {
app.get(name, function(req, res) {
res.render(name);
});
});
Is this what you meant?
Here are a couple of other solutions:
app.get(^\/article(\d{1,3})?\/?$, function(req, res, next) {
var n;
if (req.params[0])
n = parseInt(req.params[0], 10);
if (!n || (n > 0 && n < 900))
res.render('article' + (n ? n : ''));
else
next();
});
or use app.all for the first solution or use a generic middleware:
app.use(function(req, res, next) {
var m = ^\/article(\d{1,3})?\/?$.exec(req.url);
if (m) {
var n;
if (m[0])
n = parseInt(m[0], 10);
if (!n || (n > 0 && n < 900))
return res.render('article' + (n ? n : ''));
}
next();
});
Finally got it working..
In cases where I got, article1, article2 etc:
app.get('/:name(article|article2|article3)?', function(req, res) {
var name = req.params.name;
res.render(name);
});
In cases where I got multi level url, I created a custom function:
function geturl(url) {
app.get('/' + url + '/' + ':name', function(req, res){
var name = req.params.name;
res.render(url + '/' + name);
});
};
