A software component for data synchronization between a web client and a backend system

V magistrskem delu se osredotočamo na problem sinhronizacije podatkov med spletnim odjemalcem in zalednim sistemom. Ta problem postaja danes zelo pomemben pri razvoju spletnih aplikacij, saj imamo tako napredne naprave, da lahko uporabljamo aplikacije ob pogojih, ko imamo in nimamo povezave z omrežjem. Pogosto razvijalci poskušajo sami razviti neko rešitev za proces sinhronizacije. V sklopu naše naloge smo pripravili načrte procesov, za katere menimo, da so potrebni med procesom sinhronizacije na način, da bi lahko vsak razvijalec, neodvisno od tehnologije implementiral postopek na nek standarden način. Poleg načrtov smo tudi sami implementirali rešitev s pomočjo TypeScript, PHP jezikov in predstavljenimi knjižnicami, ki sledijo predstavljenim načrtom procesov. Na koncu smo s pomočjo simulacije pokazali delovanje sinhronizacijskega postopka na preprosti spletni aplikaciji, zgrajeni z ogrodjema Angular in Selenium. Simulacija potrjuje, da z omenjenimi načrti in implementacijo lahko dosežemo ključne funkcionalnosti sinhronizacije.This master’s thesis focuses on the problem of data synchronization between a web client and a backend system. This problem is currently in high demand, when developers develop web applications, since mobile devices today can run practically any kind of application, whether there is data connection or not. It is a common practice for developers to always produce some custom (unique) solution when tackling this kind of a problem. The goal of this thesis is to give developers a schema that defines all important processes within the synchronization process. By doing so, it is believed that developers would have a standardized option for implementing synchronization within their existing projects. A solution based on the provided schemas has also been implemented, combined with TypeScript and PHP languages, along with libraries that follow the proposed schemas exactly as they are shown. In the end, a simulation using the Angular and Selenium frameworks has been presented to indicate that this kind of implementation can give us key synchronization functionalities
