I am following this tutorial on building a Node/Express app.
Now the issue I am having is how to route requests with parameters.
For example a route will look like this with a pagename and then 3-6 parameters
page-name/param1/param2/param3
and in express I route that as follows:
router.get("/page-name/:param1/:param2/:param3",pageController);
This loads a controller function where I query for the parameters as follows:
var param1 = [req.params.param1];
var param2 = [req.params.param2];
var param3 = [req.params.param3];
The problem I am running into now is that I get a
cannot Get
error when a parameter is missing from the route.
For example
/page-name/
route with no parameters throws an error
and
/page-name/param1/
also throws an error because the other 2 parameters are not there.
What is the best way to deal with this issue when routing with Express?
