Request: ability to get subkey using chrome.storage.local.get()

[thdoan]

Currently the get() method only accepts three parameters:

"A single key to get, list of keys to get, or a dictionary specifying default values (see description of the object)." (Source)

If you are storing a lot of data in chrome.storage, it can be more efficient to have the ability to get a subkey in some scenarios. Example

{

  "tom": { lots of data },

  "dick": {

    "fullname": "..."

    "phone": "...",

    "email": "...",

    "history": { lots of data }

  },

  "harry": { lots of data }

}

If I just want to retrieve Dick's email, I would prefer to get only the email subkey instead of the entire dick key, which contains a huge amount of data in history. It would be great if I could pull that off by doing something like this:

chrome.storage.local.get(dick.email, function(items) {

  // Do something with Dick's email and only Dick's email

  console.log('Dick\'s email is ' + items['email']);

});

The storage doesn't index the object structure so it can't extract a subkey without extracting and parsing the entire value. That's how any storage works. You need to reorganize your object structure, for example use prefixes, to disperse it into separate keys.
