Spletne storitve z GraphQL

Kajdič, Domen (author), Jurič, Branko Matjaž (mentor)

Vsak razvijalec, ki sledi trendom, je že slišal za mikrostoritve in tehnologijo GraphQL. Čeprav se o novih tehnologijah veliko govori, se le mali delež razvijalcev odloči za njihovo uporabo. Glaven razlog pripisujejo nezrelosti tehnologij in netrivialni migraciji, ki je lahko včasih zamudnejša kot ponovni začetek razvoja. V okviru diplomske naloge smo tehnologijo GraphQL podrobneje raziskali in jo uvrstili v svet mikrostoritev. Primerjali smo jo s storitvami REST kot glavno alternativo in prikazali, v katerih primerih se nam jo splača uporabiti. Primerna je predvsem za aplikacije, ki vsebujejo poizvedovanje po kompleksnih podatkih z veliko relacijami, medtem ko so storitve REST primerne za preproste aplikacije. Kljub temu tehnologija GraphQL še vedno ni primerna za uporabo v mikrostoritah zaradi pomanjkanja programskih orodij. Zato smo za olajšanje razvoja mikrostoritev GraphQL razvili programsko rešitev KumuluzEE GraphQL. Uporabo rešitve smo prikazali na realnem primeru upravljanja fakultete in s tem prikazali njeno uporabnost v praksi.

Abstract

Every trend-following developer has heard of microservices and GraphQL. Even though new technologies are often discussed, only a minor share of developers decide to use them. The main reason is often found in immaturity of technologies and in untrivial migration, which is often more time-consuming than starting from scratch. In the context of the thesis the GraphQL technology was explored in detail and was placed in the world of microservices. It was compared to REST as its main alternative and the potential use cases were displayed. GraphQL was found to be the most suitable for complex applications with highly related data, while REST was found to be the most suitable for simple applications. Nevertheless, GraphQL is still not ready to be widely used in microservices due to the lack of software support. Therefore, we developed a tool to simplify the development of GraphQL microservices and presented its usage on an example. With that, we were able to show the usefulness of our tool on a real-life project.
