Purpose

The purpose of this component is to have support for local storage in Web REACTive applications.

IndexedDB also supports the storage of JavaScript objects which have some interesting applications.

Key concepts

IndexedDB is a transactional database system, like an SQL-based RDBMS. However, unlike SQL-based RDBMSes, which use fixed-column tables, IndexedDB is a JavaScript-based object-oriented database. IndexedDB lets you store and retrieve objects that are indexed with a key; any objects supported by the structured clone algorithm can be stored. You need to specify the database schema, open a connection to your database, and then retrieve and update data within a series of transactions.
