The Storage.extension() adapter uses the browser’s extension storage API to store data. Use this adapter if you are building a browser extension for Chrome, Firefox, or Edge.

​
Pre-requisites

You will need to enable the storage permission in your extension’s manifest.json file: 
{
  "permissions": ["storage"]
}
Optionally, you can also enable the unlimitedStorage permission to allow your extension to use more than 5MB of storage. 
{
  "permissions": ["storage", "unlimitedStorage"]
}

​
Example

import { Storage } from "@chainpatrol/sdk";

const storage = Storage.extension({
  quota: 1024 * 1024 * 5, // 5MB
});
