2.2 CONTEXTUALIZATION

This section describes the relation between Frontend and other modules of the I-REACTarchitecture.

Frontend receives information from Back-end and GeoServer modules. It does not have directaccesstotheDataLayer,usingthelasttwomodulestoread,createandupdatenewinformation.

Theconnectionwith theBack-endandGeoServermodules isdoing throughRESTservices.Bothprovemethodstoretrieveandinsertinformation.

Figure2.2-1:I-REACTarchitecture



The I-REACTOR FrontEnd is developed as Single Page Application (SPA) using Facebook React(ReactJS)+Redux.ReactJSisaJavaScriptlibrarythatprovidesthetoolstodefineanddividetheUserInterfaceintocomponentsthatcanbereusable.Furthermore,Reduxisusedtodisengagetheglobalstateofthewebapplicationfromthevisualpart,wherethisstateisboththeUIstateandthedataretrievedbyservicesthatfetchinformationfromdiversesourceslikeexternalAPIortheapplicationBackendasOAuth2.0clientoverasecurechannel(https).Then,usingReacttheFrontEndexposesspecificviewsforthedatatobedisplayed,usingaresponsiveapproach.

Figure2.2-2:DataflowbetweenReduxwebappandReactJScomponents

Theredux-fluxpatternestablishesaunidirectionaldataflowwithasinglestorefortheapplicationstate.Thisensuresthattheviewswillalwaysrespectthechangesoftheappstate,whicharefiredby actions. Actions can be related to UI interactions or other events. This allows to separatepresentation from abstract representation of the app state, while boosting performances andsimplifyingcomponentreusabilityandscopeisolation.TheReactJS-Reduxdesignallowstoseparateviewrenderingfromappstaterepresentation,writingbetterorganizedandmoremaintainableandreusablecode.Themaincomponentsofthisarchitecturearethefollowing:

� ActionCreators:thesefunctionsdefinewhichactionaredispatchedinreactiontoeventssuchasuserinteraction,network,systemorsensorevents.ActionCreatorscanbesynchronousorasynchronous.TocommunicatewiththeI-REACTORbackend,ActionCreatorswilltakeadvantageoftheWebAPImodule.

� Reducer:dependingonthetriggeredActionCreators, thereducerhas thetaskofpropagatingevents thatmutate theappstate.SinceReduxcontemplatesa singlestorefortheappstate,alltheactions,definedasplainobjects,aredispatchedbythiscentralstore.



� Store:itencapsulatesthestateoftheapplicationanditisread-only,inthesensethatneither viewsnornetwork calls candirectlymanipulate it. Theway the state canmutateisdefinedthroughsocalled“reducers”,whicharepurefunctionsthatgiventhecurrentstateandanaction,returnthenextstate.ItcanbethoughtintermsofaFiniteStateMachine(FSM)whosestatesareacompositionofeachmodulestates,andreducersareacompositionofeachmodulereducers,exploitingmodularityandreusability.Eachmodulethusdefinesaportionoftheappstatethatiscombinedtothe other portions and stored into the single store. This store is therefore ahierarchicalobjecttreewhichservesassinglesourceoftruth.

� Selector: the selectorallows togetdataoutof the store.Are functions that take

� ReactViews:roughlycorrespondingtotheVoftheclassicMVCpattern,ReactViewsaremadeofreusablecomponentsthatonlyrenderaportionofthecurrentappstate,which ispropagatedbymeanof immutableproperties inahierarchicalway.UserInterface(UI)interactionsarethenpropagatedtotheappstatebycallingtheActionCreators,thatwillupdatetheappstateandfinallypropagatetotheinterestedviewcomponents,whenneeded.

ThefrontendincludesanadditionalReduxmodule,i.e.,theWebAPI.Itistaskedtoactasaliaisonwiththebackend,managingallinteractions,bothinboundandoutbound.Whiletheproposedarchitectureisverysimilarforbothfrontendandmobileapp,eachoneofthesewill implementspecificmodulesandviewcomponentstocopewithitsownpeculiarities.Ontheotherhand, all effortswill bemade for sharing commonmodules and view componentswherepossible.

4.3 IMPLEMENTATIONENVIRONMENT

The framework selected to implement the frontend and mobile application is ReactJS, whichexploitstheredux-fluxdesignpatternandhasproventobeveryefficientforbothlargeandsmallapplicationsonbothmobileanddesktopenvironments.Theredux-fluxpatternisaspecificversionof theone-way-flowpattern.Furthermore, theReactJSdevelopers’community isvery largeandthereisgoodsupportandmaintainability.

Actually, ReactJS is only the presentation layer of a ReactJS+Redux application, thus regardingmainly theuser interfaceand routing. Thepointof strengthofReact is that itsmodules, calledcomponents, are designed for maximizing reusability, while performance are boosted bymanipulatinganoptimizedshadowDOMinsteadofaccessingtheactualDOMdirectly,propagatingonlynecessaryUImutations.MoredetailscanbefoundontheReactofficialwebsite1.

The other component of React-Redux applications is Redux, which controls and models theapplicationstateandhowstatemutationsarepropagatedtotheviewsusingtheso-calledproviders.Reduxpatternisaspecificimplementationofthefluxpattern,whichinturnbelongstothefamilyoftheone-way-flowpatterns.

Thus, Redux controls how data are accessed, represented and mutated in the app state bydescribing how data sources have to be integrated into the app state. The state of a Reduxapplicationissavedtoasinglestore,whichmayalsobeserialized,anditiscreatedbycompositionoftheconnectedReduxmodules.MoredetailscanbefoundintheReduxdocumentation2.
