Hello Martin,

Are you sure your ionic serve command finish without any error?

And better if you could try ionic serve only without --lab

This is the output from “ionic serve”

Running ‘serve:before’ npm script before serve

Ionic server commands, enter:
restart or r to restart the client app from the root
goto or g and a url to have the app navigate to the given url
consolelogs or c to enable/disable console log output
serverlogs or s to enable/disable server log output
quit or q to shutdown the server and exit

Okay, looks like you do not have error in your app syntax

Now can you manually open http://localhost:8100 in your browser, hope this will work even if ionic is not opening browser automatically.

Thanks, but I am missing the lab feature, looks cool

I found out that if you use sidemenu template the app never loads. This problem has not happened before.
The command which has problem:
$ ionic start helloWorld sidemenu --v2

You can try to use this command to start a project instead.

$ionic start helloWorld --v2

It seems this has just been fixed. Check this link Error when creating ionic 2 sidemenu template app

I am using the blank template. But thanks for letting me know.

Sometimes lack of ionic.config.json is also a reason. It is under the root directory.
Also make sure that you have run " npm -g install cordova"

Its working now, just not with chrome

{
“name”: “MyFirstApp”,
“app_id”: “12345678”,
“v2”: true,
“typescript”: true,
“defaultBrowser”: “safari”
}

Good. What have you done to fix it?

11

I think I was running ionic serve -f chrome and it must have set chrome to the default browser.
I was not aware of the ionic config file so thank for pointing me in that direction.

So I simple replaced chrome with safari.

Good that it helped:)
I normally use “ionic serve -c --lab” to test apps in my browser.
