Realm React Native
Monday, 29 February 2016

A new version of Realm mobile database has been launched, built specifically for Facebook React.js. Faster than existing options, it offers easy object persistence and full query capabilities.




Realm is a database that runs directly inside phones and other mobile devices. It provides an alternative to SQLite, using native JavaScript objects that are dynamically mapped to a full, custom database engine rather than a key-value store. This means the developers were able to develop a simple API that lets you model complex data, link objects in a graph, and compose advanced queries.

Realm was originally launched for Java, Objective-C, and Swift in 2014 and has gained wide acceptance.




The new version is designed for React Native, Facebook’s JavaScript framework. React Native lets you write JavaScript code that becomes native iOS & Android apps. Realm React Native can be used to target both iOS and Android with the same codebase. While the public launch was only made this week, Realm React Native has already been used in production for over two months by TaskRabbit.

TaskRabbit is an app that lets you find local people who are willing and able to carry out tasks for you. Brian Leonard, co-founder of TaskRabbit, said that using Realm and React Native made him ten times more productive than when developing a regular iOS app, and meant there was:

"a decent chance much of the code could be reused on Android. If every feature did not have to be developed twice, we could choose to develop twice as many features or have half the engineers work on something else."

The Realm team plans to add support for other platforms including Cordova and Node.js (V8) in the future.
