Thank you! The peer dependency warnings are remnants of our time in alpha. I've loosened the requirements now that things have stabilized a bit and the warnings no longer appear. 🎉 The fix was here and here.

The issues npm audit is warning about mostly related to dependencies of karma. We will update once 3.0 comes out (see this issue). Every new Angular app right now has more than double the number of "vulnerabilities" according to npm and it's not going to be addressed in this issue.

Most of the deprecated modules are also from karma.

The deprecation/audit warnings aren't pretty, but they're a result of the absolutely _massive_ dependency tree modern JS apps deal with. The issue exists far downstream from Ionic, and affects many others outside Ionic. If you run npm audit for a detailed report, you can see the "path" of dependencies. For example, this issue about hoek is due to this dependency path: karma > log4js > loggly > request > hawk > hoek. The fix must come from hawk, then request, then loggly, then log4js, then karma before ionic start will cease to give that warning.

Thanks for the issue! Unless I'm missing something, I'll be closing it as I believe it is resolved.

Karma 3.0 comes out. If possible, please, update.
