Where is chrome.storage.local stored for Chrome Apps?

Question

Where is chrome.storage.local stored for Chrome Apps in OSX yosemite?

Answer 1

I finally found it: ~/Library/Application Support/Google/Chrome/Default/Local App Settings/{{chrome-app-id}}. The whole {{chrome-app-id}} folder is a leveldb database. I was able to open it and inspect the contents of the stored file using the leveldb-ruby gem. Just do the following

require 'leveldb'
db = LevelDB:DB.new '~/Library/Application Support/Google/Chrome/Default/Local App Settings/{{chrome-app-id}}'

You can now query the database using the db object. By the way if you get a weird error saying that the db is being used by someone else make sure you kill chrome and erase the LOCK file.

Answer 2

localStorage is located in ~/Library/Application Support/Google/Chrome/Default/Local Storage. You'll need the ID to find the correct files but they'll be prefixed with chrome- and have a file extension of .localstorage.

Based on some picking through the POSTMan App, it looks like it makes a call to chrome.storage.local and the data on my Mac is located here: ~/Library/Application Support/Google/Chrome/Default/Local App Settings/<ID>/000003.log.
