You can’t. Ionic 4 will allow for Angular routing though.
is it possible to implement angular 4 routing in ionic ? .if yes can you give example code
No. It is not. Same answer as before.
what is the best practice to implement the url routing in ionic3
Use the routing that is there in Ionic or wait for a new version to be released that does it different.
