How to configure dynamic routes with express.js

Question

I have a route.js which looks like this:

module.exports = function(app) {

  app.get(\'/tip\', function(req, res) {
    res.render(\"tip\");
  });

  app.get         


        

Answer 1

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(); 
});
