Assuming you have a numeric identifier followed by iand you want the identifier to be returned as numeric only.

app.get("/:id([0-9]+)i", function (req, res) {...});

This will match the number that follows i, and you will only get a numeric value in req.params.id.

Example:

curl -XGET localhost:8080/124i

Gives me the following in req.params

[ 'id': 124 ]
