Change to flow router so your route only reside in client and so it does not bother you.
Iron-router reside both side (client/server) and will get in your way, or you will have to work with iron router server side routes.
This should be possible with Iron Router as well. I believe you need to define the route and specify it to be on the server only. Here is a piece of code from a project where I was playing with this.
So getting iron router is not the issue, that works fine. But I have the feeling that because iron router is active my ‘express server’ is not being called. (the code is not being executed)
or the issue could be that my express server is not really running? Because both iron router as well as express should be able to listen to the same path?
