Mawonekedwe a intaneti a Pusa adasindikizidwa ndikukhazikitsa lingaliro lomwe limasamutsa malingaliro akutsogolo, omwe amachitidwa mumsakatuli pogwiritsa ntchito JavaScript, kupita kumbuyo - kuwongolera osatsegula ndi zinthu za DOM, komanso malingaliro abizinesi amachitidwa pa. kumbuyo-mapeto. Khodi ya JavaScript yomwe ili pambali ya msakatuli imasinthidwa ndi chosanjikiza chapadziko lonse chomwe chimayitanira ma handlers omwe ali kumbali yakumbuyo. Palibe chifukwa chopangira JavaScript kutsogolo. Kukhazikitsa kwa Pusa kumalembedwa mu PHP ndipo kuli ndi chilolezo pansi pa GPLv3. Kuphatikiza pa PHP, lusoli likhoza kugwiritsidwa ntchito m'chinenero china chilichonse, kuphatikizapo JavaScript/Node.js, Java, Python, Go ndi Ruby.
Pusa imatanthauzira ndondomeko yosinthira kutengera malamulo ochepa. Tsamba likadzaza, msakatuli amanyamula zomwe zili mu DOM ndi Pusa-Front's JavaScript core. Pusa-Front imatumiza zochitika za msakatuli (monga kudina, kusokoneza, kuyang'ana ndi keypress) ndikupempha magawo (chinthu chomwe chinayambitsa chochitikacho, zizindikiro zake, URL, ndi zina zotero) kwa Pusa-Back seva chogwiritsira ntchito pogwiritsa ntchito zopempha za Ajax. Kutengera zomwe zalandilidwa, Pusa-Back imasankha wowongolera, amalipira malipirowo ndikupanga malamulo angapo oyankha. Atalandira yankho la pempho, Pusa-Front imapanga malamulo, kusintha zomwe zili mu DOM ndi malo osatsegula.
Mkhalidwe wa kutsogolo umapangidwa koma sulamulidwa ndi backend, zomwe zimapangitsa kuti Pusa ipangidwe mofanana ndi kulemba ma code a khadi la kanema kapena Canvas, komwe zotsatira zake sizimayang'aniridwa ndi wopanga mapulogalamu. Kuti mupange mapulogalamu olumikizana pogwiritsa ntchito Canvas ndi onmousemove, ndizotheka kuyika ndikugwiritsa ntchito zolemba zina za JavaScript kumbali ya kasitomala. Zoyipa za njira iyi zimaphatikizaponso kusuntha katundu wina kuchokera kutsogolo kupita kumbuyo ndikuwonjezera kuchuluka kwa kusinthana kwa deta. Seva.
Zina mwazabwino ndi izi: kuchotsa kufunikira kwa kutenga nawo gawo kwa opanga mapulogalamu akutsogolo a JavaScript, khodi yokhazikika komanso yophatikizika yamakasitomala (11kb), kusapezeka kwa kachidindo yayikulu kuchokera kumapeto, kusafunikira kwa REST ndi zida monga gRPC, kuchotsa zovuta zogwirizanitsa zopempha pakati pa kutsogolo ndi kumbuyo.
