Chrome extension store large amounts of data

Question

I\'m looking for an efficient way to store large amounts of data in my chrome extension. I\'ve got a few txt files which are around 1-2mb. I\'d like my chrome extension to \

Answer 1

Only WebSQL, IndexedDB, chrome.storage.local and HTML5 File System (sandboxed file system) can grow past 5MB limit via "unlimitedStorage" permission.

manifest.json: "permissions": ["unlimitedStorage"]

Provides an unlimited quota for storing HTML5 client-side data, such as databases and local storage files. Without this permission, the extension or app is limited to 5 MB of local storage.

Notes:

• WebSQL is deprecated by W3C in favor of the slower IndexedDB but I think it will stay in Chrome for the obvious reason that it's faster and more flexible due to being SQL-based.
• chrome.storage.local is the easiest to use but it may not be the fastest with the large objects, do some tests if speed is important.
• Use a Zip/LZMA Javascript library to compress/decompress the text files if the gain is significant.
