This technology has been around for a while (> 3 years) and I haven’t used it personally, but it’s pretty damn slick. IndexedDB is a low-level API for client side storage. Its more popular brother, localStorage has its limitations and if you’re ever running into them, you might want to take a look at IndexedDB. In a nutshell, IndexedDB is a transactional database system that allows us to permanently store data inside a user’s browser. It would be useful for applications that store a large amount of data and applications that don’t need persistent internet connectivity to function.

Keep these key things in mind:

• It stores key-value pairs.
• It’s built on a transactional database model.
• The API is mostly async.
• It’s object-oriented 😲.
• It’s not SQL
• It adheres to the same origin policy.
