My app works fine as long as I run ionic serve, but when I run or build it is like my own build doesn’t follow along. The main.js file is to small for everything to be included. The app has the white screen of death =P. No errors nothing… What am I doing wrong here?

So… no I at least get some errors but the console says it does not find the templates.

Failed to load resource: net::ERR\_FILE\_NOT\_FOUND  
polyfills.js:3 Unhandled Promise rejection: Failed to load toolbar.html ; Zone: ; Task: Promise.then ; Value: Failed to load toolbar.html undefined

Isn’t the html-files supposed to be built in?
