There is “ionic serve” which runs it in a browser.
There is “ionic emulate [platform]” which brings up emulater
I saw a third method somewhere, it is similar to “ionic serve” and runs it in the browser, I think it needed Chrome Canary, but the difference is that when I ran it this way, it displayed in a mobile device similar to the full blown emulator but in a web page view…But I forgot how to do this! I don’t remember which tutorial mentioned this, I remember seeing it in a tutorial a month ago…
