Display nothing after ng serve

[pierre03]

Hello,
I have launched the command: npm install =>OK
then: ng serve => OK, but nothing on the screen...
These are the messages in the web socket:

o
a["{\"type\":\"overlay\",\"data\":{\"errors\":true,\"warnings\":false}}"]
a["{\"type\":\"hash\",\"data\":\"73ad0a685ebfc6759a65\"}"]
a["{\"type\":\"ok\"}"]

Can you tell me why?

Cause there is no route for it.
Check AppRoutingModule
Hit enter-room

default routing in landing page is empty.
try :

http://localhost:4200/create-room
http://localhost:4200/enter-room
http://localhost:4200/room/2
