Izingxenye ze-Relay zakha umgogodla wezinhlelo zangaphambili zesimanje ezisekelwe kudatha, ezivumela abathuthukisi ukuthi bachaze ukuncika kwedatha ngokumemezela. Ezinhlelweni eziyinkimbinkimbi lapho izingxenye ze-UI kumele zithole futhi zihlanganise idatha kusuka kuseva ye-GraphQL, izingxenye ze-Relay zisiza ukuphoqelela ukungaguquguquki, ukubeka imibuzo eduze nezingxenye ezidinga idatha. Umphumela ubucacisa ubunikazi bedatha, izicelo zenethiwekhi eziphindaphindayo ezimbalwa, nokuhlinzekwa okubikezelwe kakhudlwana. Amaqembu akha izinhlelo zokusebenza zewebhu ezisebenza kakhulu, ukuqonda izingxenye ze-Relay kubalulekile ukwenza ngcono ukuthola, ukugcina, nokuguquguquka kwesimo. Lesi sethulo sihlanganisa izizathu ezisebenzayo nezokwakhiwa ukuze kwamukelwe i-Relay njengengxenye yamasu aqinile wezingqimba zedatha.

Inhliziyo ye-Relay iqukethe izingxenye eziningana ezihlangene: Iziqukathi ze-Relay (Relay Containers), Izicucu ze-GraphQL (GraphQL Fragments), kanye nesitolo se-Relay (Relay Store). Iziqukathi ze-Relay zigqoka izakhiwo ze-UI futhi zimemezela imibuzo esekelwe ezicucwini ezidingekayo, leyo i-Relay eyakha ibe izicelo zenethiwekhi ezisebenzayo. Izicucu zichaza ukuma okunembayo kwedatha okudingwa isakhiwo, okuvumela ukuhlukahluka nokusetshenziswa kabusha kuwo wonke uhlelo lokusebenza. Isitolo se-Relay sigcina amarekhodi agcinwe ngokujwayelekile wedatha yeseva, sihlanganisa ukufundwa nokubhala kwendawo ngendlela esekela izibuyekezo ezibonakalayo kanye nesimo esingaguquki se-UI. Ngokubambisana, lezi zakhiwo ze-relay zinciphisa ukuxhumana phakathi kwezakhiwo nekhodi yenethiwekhi ephansi, okwenza kube lula ukucabanga ngezindlela zedatha.

Ama-Relay Containers asebenza njengesixhumanisi phakathi kwe-UI nedatha ngokuchaza imingcele yezingxenye eduze nokuqaliswa kwekhompawundi. Leli phatheni likhuthaza ama-component anomsebenzi owodwa acela kuphela lokho akwenzayo, kuthuthukisa ukusetshenziswa kabusha nokugcinwa. Ama-Containers aphinde asize lapho ehlangene namakhasi asezingeni eliphezulu: I-Relay ihlanganisa izingxenye ezivela ezinganeni zibe umbuzo owodwa, okunciphisa ukuthola okungaphezulu kanye namasimu angafuneki aphindaphindwe. Kuba thuthukisi abafudukela ezinhlelweni ezindala, ukuguqula ama-component ahlakaniphile abe ama-Relay Containers kungaba yisinyathelo esisebenzayo esiya kwingqimba yedatha ecacile. Ngakho-ke, ukuqonda ama-containers kubalulekile ekwakheni ama-component angalindeleka, angahlolwa.

Ama-fragments akuvumela ukuthi uchaze izinkambu ezidingekayo kumphakathi ngaphandle kokuxhumanisa lezi zinkambu ne-query ethile. Le modularity ivumela ama-fragments ukuthi ahlanganyelwe phakathi kwezikhala futhi akhiwe ngokuzenzakalelayo abe ama-query ahloliwe nguRelay. Lapho ama-component amaningi efuna idatha efanayo, uRelay uyasusa izinkambu eziphindaphindiwe futhi uhlanganise izicelo zeseva, uthuthukisa ukusebenza kwenethiwekhi. Ama-fragments futhi enza ukuthi ukuhlela kube kuphephile: lapho izakhiwo zomphakathi zishintsha, kuphela i-fragment yalowo mphakathi evame ukuba nesidingo sokulungiswa, inciphisa ububanzi bokushintsha. Empeleni, ukuklama ama-fragments ngokucophelela kuholela ezinkingeni ezincane, izikhwama ezincane, nezikhathi zokuhumusha ezisheshayo.

Ukuqala uhlelo lokusebenza lwe-Relay kuqala ngokuqonda isakhiwo sedatha (schema) kanye nephuzu lokuphela le-GraphQL. Okokuqala, faka i-Relay bese usetha isihumushi (compiler) ukukhiqiza izinto ezidingekayo kusuka kuma-fragment akho; lokhu kuhlanganiswa kusengaphambili kunika amandla ukuphepha kwezinhlobo (type safety) nokuziphatha okubikelekayo lapho uhlelo lusebenza. Okulandelayo, guqula isihlahla somsebenzisi (UI tree) sibe iziqukathi ze-Relay ngokukhomba idatha edingwa yisiphi isakhiwo bese uyikhomba njengama-fragment. Bese uhlanganisa ukusebenza kwesendlalelo senethiwekhi (network layer) bese ulungisa i-Relay Store ukugcina nokwenza izimpendulo zibe ezijwayelekile. Ekugcineni, hlola imibuzo ehlanganisiwe bese usebenzisa i-Relay DevTools ukuhlola isitoreji nomsebenzi wenethiwekhi ukuqinisekisa ukuthi izakhiwo zithola izimo zedatha ezilindelekile. Ukulandela lezi zinyathelo kuzokhiqiza uhlelo lokusebenza olulungisekayo oluzuzwa ngokuthuthukiswa kwezakhiwo ze-relay.

Cabanga ngomklamo wohlu/imininingwane: Isakhiwo soHlu sihlola iqoqo futhi sibonise izakhiwo zeZinto, ngalunye lunikeza ingxenye yalo yemibhalo yezinkambu zokubonisa. I-Relay ihlanganisa lezi zingxenye zibe umbuzo owodwa wokuthola uhlu, noma ngabe izinto zikhona emakhasini ahlukaniswe ngamakhasi. Lapho into ikhethwa, isakhiwo soMINiningwane singase sichaze izingxenye ezengeziwe zezinkambu ezandisiwe, futhi i-Relay izothola lezo zinkambu kuphela njengoba zidingeka. Le modeli yokuthola ngokufunwa inciphisa imithwalo yokuqala futhi isekela amamodeli wokulayisha okwandayo ukuze uthole ukusebenza okungcono okubonwayo. Ukusebenzisa le modeli ngendlela efanele kudinga ukuqonda ukuthi izakhiwo ze-relay zihambisana kanjani nokuhlanganiswa kwezingxenye nokuhlukaniswa ngamakhasi.

Isendlalelo sedatha se-Relay silawula ukuthi imibuzo ithunyelwa kanjani, izimpendulo zihlelwa kanjani esitolo se-Relay, nokuthi izibuyekezo zisakazwa kanjani kumakhekhona. Isitolo se-Relay sihlanganisa amarekhodi ngeziqhakambisi eziyingqayizivele, sivumela izibuyekezo ezisebenzayo nokufundwa okuhambisanayo kuwo wonke amakhekhona amaningi. Ngezici ezifana nezibuyekezo ezibonakalayo nokuqoqwa kukadoti, i-Relay isiza izicelo ukuthi zihlale zisebenza ngenkathi igcina osayizi bekheshi uphathekayo. I-runtime iphinde isekele izindlela ezahlukene zokuthola—inethiwekhi kuphela, isitolo noma inethiwekhi, nesitolo bese kuba inethiwekhi—ngakho-ke abathuthukisi bangalungisa ukubambezeleka okubonwayo nokusha. Ukwazi kahle lezi zindlela kubalulekile ukugwema i-UI emile nokukhulisa inzuzo yamakhona e-relay.

Ngaphandle kwemibuzo, izingxenye zokudlulisa zihlanganisa nokuguquguquka nokubhaliswa kwesikhathi sangempela ukuze kugcinwe isitoreji sivumelana nezinguquko eziseceleni zeseva. Ukuguquguquka kufaka phakathi ukucushwa kwezibuyekezo ezibonakalayo nemisebenzi yokubuyekeza ukuze kuguqulwe isitoreji ngokuqondile ngemuva kwezimpendulo zokuguquguquka. Ukubhaliswa kucindezela izinguquko eziseceleni zeseva kumaklayenti futhi kufanele kuhambisane namarekhodi akhona asekhona ukuze kugwenywe ukungahambisani. Ukusebenzisa lezi zici ndawonye kusekela okuhlangenwe nakho okuyinkimbinkimbi komsebenzisi njengokuhlela okubambisanayo, amadeshibhodi abukhoma, nezinqubo zokubuyekeza ezisheshayo. Lapho kusebenza kahle, izingxenye zokudlulisa zinikeza imodeli evumelanayo yokusebenzisana kokufunda nokubhala.

Ukuze uthole okuningi kusuka kumalungu e-relay, yamukela izindlela ezihamba phambili ezibeka phambili inhloso nokusebenza kahle. Hlanganisa iziqephu namalungu, khetha iziqephu ezincane ezigxilile kunama-query blobs amakhulu, futhi usebenzise iziqukathi zokuhlukanisa izinhlu ezinkulu ukuze ugweme ukulayisha konke ngesikhathi esisodwa. Gada izimo ze-query nosayizi be-payload ngamathuluzi okuhlola, futhi uvule izimfuno eziqhubekayo noma ukuhlungwa kwezimfuno ukuze unciphise umthwalo weseva. Futhi, sebenzisa izici zesimanje ze-Relay njengokulayisha izimfuno kusengaphambili lapho ushintsha imizila ukuze unciphise ukubambezeleka okubonwayo. Ukulandela le miqondiso kusiza amaqembu ukuthi agcine ukucaca mayelana nobunikazi bedatha ngenkathi kuncishiswa izindleko zenethiwekhi nokuhlinzeka.

Khetha izinqubomgomo ezifanele zokuthola ngokuya ngezilindelo zomsebenzisi: isitolo-noma-inethiwekhi ukuze uthole imibono esheshayo edinga ukuvuselelwa ngezikhathi ezithile, inethiwekhi kuphela ukuze uthole idatha ebalulekile yesikhathi sangempela, kanye nesitolo-bese-inethiwekhi ukuze uthole ukubuka okusheshayo okulandela ngezibuyekezo. Faka ukuphindaphinda nezindlela zokuxhumana ukuze unciphise usayizi wezicelo ngamunye futhi usebenzise izindlela ezifanele zokuphula ikheshi ngemuva kokushintsha. Kuma-apps amakhulu, cabanga ngama-queries agcinwe ukuze unciphise umthwalo wokuhlaziya ama-queries kuseva futhi ukhiqize izinyathelo ezincane zenethiwekhi. Lezi zindlela zokwenza, ezihlanganiswe nezakhiwo ezihlelwe kahle ze-relay, zikhokelela kumasistimu efronthendi aphendulayo, akwazi ukukhula.

Abathuthukisi bavame ukubhekana nezinselelo ezifana nokuthola idatha eningi kakhulu (over-fetching), ukungqubuzana kwamafragmenthi (fragment collisions), kanye nezinqubo eziyinkimbinkimbi zokubuyekeza (updater logic) zokuguqula isitoreji (store mutations). Ukuthola idatha eningi kakhulu (over-fetching) kuvame ukuvela kumafragmenthi amakhulu; wahlukanise izibe izingxenye ezincane ukuze i-Relay ikwazi ukukhipha izinto eziphindaphindayo nokuhlanganisa kangcono. Ukungqubuzana kwamafragmenthi—lapho amafragmenthi ahlukene elindele ukwakheka okungahambisani—kungaxazululwa ngokuhambisa izinkontileka zamafragmenthi nokusebenzisa amagama-mbuyiselo enkundleni (field aliases) njengoba kudingeka. Ukuphathwa okuyinkimbinkimbi kwezibuyekezi (updater complexity) kwandisa nesimo sohlelo lokusebenza; bhala imisebenzi emincane, elula ukuyihlola (testable updater functions) futhi ubhale imiphumela yokuguqulwa (mutation effects) ukuze unciphise ukubuyela emuva. Ngokunaka lezi zindawo, izingxenye ze-relay ziba lula ukuziqonda nokuzigcina.

Ukuhlanganisa i-Relay kumakhodi akhona kungaveza izinkinga zokusebenzisana nezingxenye zokuzulazula, izilawuli zesimo, noma izendlalelo zenethiwekhi ezindala. Ukunciphisa ubunzima, yamukela isu lokuthuthela kancane kancane: gcoba izici ezintsha nge-Relay bese usebenzisana nekhodi endala ngama-adaptha achazwe kahle. Qinisekisa ukuthi ukuphathwa kwamaphutha kuhambisana nokutholwa kwedatha nokuthi izinqubomgomo zokuzama futhi/noma ukubuyela emuva zihambisana nokulindelekile kwe-backend. Ukufundisa ithimba mayelana nezingxenye ze-relay nokuhlinzeka ngezibonelo zezindlela ezijwayelekile—ukubeka amakhasi, izibuyekezo ezibonakalayo, nokuhlanganiswa kwezingcezu—kuzofinyeza isikhathi sokufunda futhi kunciphise amaphutha abizayo.

Izingxenye ze-Relay zivula indlela ehlakaniphile, esebenza kahle yokuthola idatha egcizelela ukuhlukahluka, ukugcina idatha, nokuncika kwedatha okuchazayo. Izicelo ezakhiwe nge-Relay ngokuvamile zithola uhambo oluncane lwenethiwekhi, ubunikazi bedatha obucacile, kanye ne-UX ebushelela kakhulu ngezici ezifana nezibuyekezo ezithemba ukuthi zizokwenzeka nokulayisha okuyingxenye. Amakhono athuthukile—izinto ezihlanganisiwe, imibuzo egciniwe, kanye nokuqoqwa kukadoti okuhlukahlukene—sekela izidingo ezisezingeni lokukhiqiza zesikali nokusebenza.
