Redirect all trailing slashes globally in express

Question

I am using Node.js and Express and I have the following routing :

app.get(\'/\', function(req,res){
    locals.date = new Date().toLocaleDateString();

    r         


        

Answer 1

One liner:

router.get('\\S+\/$', function (req, res) {
  return res.redirect(301, req.path.slice(0, -1) + req.url.slice(req.path.length));
});

This will only catch the url's that need to be redirected, and ignore the others.

Example results:

/         ==> /
/a        ==> /a
/a/       ==> /a
/a/b      ==> /a/b
/a/b/     ==> /a/b
/a/b/?c=d ==> /a/b?c=d
