Safari unable to use in private mode

[neviaumi]

While safari running on private mode window.localStorage will be available (not null/undefined ) but setItem will throw exception . It will make data loss while user this library to tracking .

Currently my solution is create custom in-memory storage to replace default storage while below condition is fulfilled :

testStorageAvailable=()-> storage = window.localStorage if storage? try storage.setItem("Storage Available", "true") return true catch e return false else return false

This should be resolved in v0.9.1
