I had tried that.
I tried -http://localhot:3000/getmejson ( full url ) and just "/getmejson".
Feels to me I am missing something big in MEAN app. May be some concept to
incorporate. My front end get request is not caught by my backend. Both are
in same project with front end in "client" folder. I build client code and
run the app on 3000.
localhost: 3000 => takes to me front end served index html. Button clicks
captured and http.get called. I use HTTPClientModule( angular 4) . From
there, it should be express backend getting the get call and sending to
router.
Included routers, body parsers, static directory and headers info and
router for that route "/getmejson"
Did I need to use any other modules at any end? I am still learning and do
not know design and coding practices with MEAN framework.
