When should you use IndexedDB?

Question

You might use IndexedDB to store structured data that's unrelated to any data on the server. An example might be a calendar, a to-do list, or saved games that are played locally. In this case, the application is really a local one, and your web site is just the vehicle for delivering it.

Should I use IndexedDB or LocalStorage?

LocalStorage is slightly faster than IndexedDB in all browsers (disregarding the crashes). IndexedDB is not significantly slower when run in a web worker, and never blocks the DOM that way.

Why is it better to use IndexedDB instead of LocalStorage?

localStorage is useful for storing smaller amounts of data, it is less useful for storing larger amounts of structured data. So if you want to store significant amounts of structured data then IndexedDB is what you should choose.

Is IndexedDB deprecated?

The W3C has announced that the Web SQL database is a deprecated local storage specification so web developer should not use this technology any more. indexeddb is an alternative for web SQL data base and more effective than older technologies.

Is it safe to use IndexedDB?

The short answer is IndexedDB is vulnerable to malware and physical takeover attacks. It's better than many options because cryptography is done outside the browser execution environment, but it's not totally secure.
