RemoteStorage – sync localStorage across devices and browsers
Hey HN! Wanted to share a new library and server I've recently been working on called remoteStorage. When building frontends with Javascript, the native localStorage API is super useful for keeping track of state between sessions in the same browser, but it's not as good a solution when your data needs to be shared across multiple devices or browsers. For instance, let's say you want to show a welcome modal to all new users that sign up for your product. If you use localStorage to track if a user has already seen this modal, your users will end up getting the experience repeatedly every time…

In plain words
RemoteStorage is a JavaScript library and server that extends localStorage functionality across multiple devices and browsers. It uses the same API as the native localStorage, allowing developers to sync application state between sessions without data loss when users switch devices or browsers. The tool is designed for frontend developers building web applications that need persistent, cross-device data management.

Talanoa▲340Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself.
