Process of development mobile application in React Native

U ovom radu je pisano o cjelokupnom procesu izrade jednostavne mobilne aplikacije pomoću novog pojednostavljenog i praktičnijeg JavaScript jezika. JavaScript je objektno orijentirani skriptni programski jezik koji se temelji na Java programskom jeziku, ali za razliku od Jave nije klasno orijentiran. React Native je okvir za programiranje u JavaScript jeziku koji održavaju i daljnje usavršavaju skupina pojedinaca i poduzeća na čelu s Facebookom. U veljači 2015. godine je React Native predstavljen, a već u ožujku iste godine je postao ''Open source''. Taj način omogućuje svim zainteresiranima da gledaju, modificiraju, mijenjaju i dijele kod, što pomaže u daljnjem razvoju i prilagodbi React-a. Do 18. travnja 2017. godine React Native je bio najnovija verzija React-a kad je objavljen React Fiber koji bi trebao postati temelj svakog unapređenja za korisničko sučelje. Cilj React Native-a je da standardizira pojednostavljenu verziju JavaScripta , te pojednostavi programerima pisanje koda i izradu aplikacija. Neke od aplikacija koje koriste React Native su: Facebook, Instagram, Skype, Wix… U ovom radu je objašnjena teorijska podloga, te postupak preuzimanja i instalacije potrebnih alata, programa i načini njihovog korištenja kako bi se stvorila osnova za izradu mobilne aplikacije. Osim preuzimanja i instalacije u radu je prikazan i primjer izrade mobilne aplikacije za stvaranje bilješki. Opisane su i objašnjene sve linija koda, te su vizualne promijene prikazane slikama.This paper describes the whole process of creating a simple mobile application with new, easier and more practical JavaScript language. JavaScript is an object-oriented scripting programming language which is based on Java programming language, but unlike Java, it is not class oriented programming. React Native JavaScript framework is maintained and further developed by the group of individuals and company's with Facebook in front. In February 2015. React Native is introduced to the public and in March of the same year it became ''Open source''.That way it was enabled to all that are interested in ReactNative to modify, inspect, change and share the code which helps in further development and the adjustment of React. Till the 18. April 2017. React Native was the newest version of React, then React Fiber was announced which would become the foundation of every user interface upgrades. Goal of the React Native is to standardize a simplified version of JavaScript and to make the writing code and creating applications easier to programmers. Some of the applications that were built using React Native are: Facebook, Instagram, Skype, Wix… In this paper theoretical background is explained as well as downloading and installing needed software and their use for creating a mobile application. Besides downloading and installing, the example of how to create mobile application for creating notes is shown. The code is described and every visual change is shown through the pictures
