Is IndexedDB slower than LocalStorage?
In both Firefox and Chrome, IndexedDB is slower than LocalStorage for basic key-value insertions, and it still blocks the DOM. In Chrome, it’s also slower than WebSQL, which does blocks the DOM, but not nearly as much.
What should IndexedDB be used for?
IndexedDB is a way for you to persistently store data inside a user’s browser. Because it lets you create web applications with rich query abilities regardless of network availability, your applications can work both online and offline.
Is IndexedDB SQL?
IndexedDB is a transactional database system, like an SQL-based RDBMS. You need to specify the database schema, open a connection to your database, and then retrieve and update data within a series of transactions. Read more about IndexedDB key characteristics and basic terminology.

Does IndexedDB block main thread?
One of the key features of IndexedDB is its asynchronous API, but don’t let that fool you into thinking you don’t need to worry about performance when using it. There are a number of cases where improper usage can still block the main thread, which can lead to jank and unresponsiveness.
Is IndexedDB any good?
As I’ve alluded to, IndexedDB is a good fit if your client-side data needs are more complex than what Local/SessionStorage can provide (i.e. you’re looking for more than a simple Key/Value store in your application). Yes, you can use JavaScript functions (such as JSON. stringify and JSON.
Is it good to use IndexedDB?
Is IndexedDB fast?
These are gets on a single index in a single store on a database. Gets are blazing fast in IndexedDB. The issue with IDB at scale is typically writes. Writes are much slower – bursty at first, but then slow after minutes and dog slow after hours.
Is SQLite obsolete?
The browsers Google Chrome, Opera, Safari and the Android Browser all allow for storing information in, and retrieving it from, a SQLite database within the browser, using the Web SQL Database technology, although this is rapidly becoming deprecated (namely superseded by IndexedDB).
