Aug 30, 2017 · we are going to explore different approaches for persisting and retrieving data in cross-platform desktop applications, built using the Electron platform and web technologies, we'll also cover how to install the required tools, write some sample code, and then see some pros and cons of each approach. Learn to use HTML5 to persist data on the client using Web Storage (local and session storage), the client-side object database known as IndexedDB and the in-browser file system. In this course you are introduced to each persistence medium and will learn to abstract away the complexities of using the raw APIs. For more complex use cases, there is IndexedDB. While it can be a good solution we recommend to only use it when absolutely necessary, due to the increase in complexity and a somewhat clumsy API. We have also had positive experience with the localForage framework that provides an abstraction layer over the various persistence solutions. @hugojosefson/virsh-transient-disk. Description.

WebSQL, IndexedDB, and FileSystem have the abilities to store data on browser depending on size, performance, and necessity. App Cache was introduced in HTML5.

Chrome also uses IndexedDB, and it determines the amount of storage available on the user’s hard drive and uses that to calculate a limit. Opera 15+ shares a codebase with Chromium/Blink, and behaves similarly. Internet Exporer 10+ has a hard 250MB limit, and will prompt the user with a non-modal dialog at 10MB. Abstract: Data persistence refers to an characteristic that data needs to outlive its creator. In recent years, NVM (Non-volatile Memory), a new type of computer memory supporting memory-like byte-addressable access and disk-like persistence, became a promising technique for facilitating data persistence in memory and its management.
