As title says I can access extension local storage through api but can't see any keys and values through developer tools. Below is the code which I use to store and get keys in local storage.
Storing value
chrome.storage.sync.set({
'handle': any-variable-which-have-some-value
});
Accessing value
chrome.storage.sync.get('handle', function (savedHandle) {
console.log(savedHandle.handle);
});
So how can I see stored values from developer tools?
Open F12 tool and switch to the context of your extension, then type your code in console, you will get the storage.
The following answer just provides some alternatives, check it out. How do I view the storage of a Chrome Extension I've installed?
