React Native mobile application for connecting to symbIoTe middleware

React Native je programska knjižnica koja omogućuje razvoj aplikacija za više platformi uz dijelenje većine koda i korištenje prirodnih mogućnosti platforme. sym- bIoTe je programski okvir za povezivanje različitih IoT platformi. Cilj ovog rada je bio pružiti osnovni pregled programskih knjižnica React i React Native, usporediti ra- zvoj aplikacije pomoću programske knjižnice React Native i prirodni načina razvoja aplikacija za Android koristeći programski jezik Java te na kraju pomoću program- ske knjižnice React Native napraviti klijentsku mobilnu aplikaciju za povezivanjem s okvirem symbIoTe.React Native is a software library that allows developing multiplatform applications while sharing most of the codebase and using native platform capabilites. SymbIoTe is a framework for connecting different IoT platforms. The aim of this paper was to overview software libraries React and React Native, compare the application develo- pement process and application capabilites of React Native with native Android and lastly to develop a mobile symbIoTe client application for Android using React Native software library
