Imikhawulo ye-eksisi ku-MATLAB - isici esiyisisekelo esinikela enqubweni yokubuka idatha enemininingwane eminingi futhi elawulwayo. I-MATLAB, ulimi lokuhlela kanye nemvelo yekhompuyutha yezinombolo, ihlinzeka ngenqwaba yemisebenzi ukuze iguqule izakhiwo zesithombe futhi imikhawulo ye-eksisi idlala indima ebaluleke kakhulu ekubukeni ububanzi obuthile nokwenza ihluzo zinembe kakhulu futhi zisebenze kahle.
i-JavaScript
Ngemva kokudalwa kwewebhu nge-HTML kanye nesakhiwo sayo nge-CSS, i-JavaScript isiwulimi esingaxhumana ngalo nomsebenzisi esipheqululini.
Kodwa uma lokhu kungezwakali njengokukhulu kuwe, umsebenzi weJavaScript wedlulele, waba ulimi lwabo bobabili abathuthukisi be-FrontEnd kanye ne-BackEnd.
Izinhlaka eziningi zidaliwe ngokusekelwe ku-JavaScripts.
Singathuthukisa noma yini kuhlanganise ne-AppWeb edumile.
Ngaphandle kokungabaza, i-JavaScript iwulimi wonke umklami okufanele alwazi kahle namuhla.
Kulesi sigaba sikusiza ngokungabaza okuvamile kanye nezinkinga zansuku zonke.
Kuxazululiwe: funda izinhlaka ze-url
Isingeniso
Kusimo sezwe sedijithali samanje, amapharamitha e-URL abalulekile njengoba evumela ukulandelela ulwazi lomthombo kubhekiselwa kuzibalo. Ukwengeza, zenza onjiniyela bakwazi ukwenza kube ngokwakho ukuzizwisa ngomsebenzisi ngamunye. Empeleni, amapharamitha e-URL ayindlela yokulondoloza izifunda endaweni engenasimo efana newebhu. Ukusebenza namapharamitha e-URL ku-TypeScript, isethi ethayiphiwe ngokuqinile ye-JavaScript, kunikeza onjiniyela ithuba lokusebenza ngokuphepha nangokuzwakalayo bazi ukuthi zonke izinhlobo ziyahlolwa ngesikhathi sokuhlanganiswa.
Kuxazululiwe: init
Impela, nasi isibonelo sokuthi ngingabhala kanjani indatshana ezungeze i-Typescript nemfashini.
Uhlobo isiphenduke isiguquli segeyimu emkhakheni wezinhlelo, ihlinzeka ngokuthayipha okumile ekuthuthukisweni kwewebhu futhi iletha namandla ezilimi zokuhlela zesimanje ku-JavaScript. Mayelana nemfashini, iyinkambu eshintsha njalo, enempilo - ulimi ngokwalo. Yize kubonakala kuhlukene, i-Typescript nemfashini zabelana ngolimi olufanayo: ubuhlakani, ukuqamba okusha, namandla.
Ixazululiwe: ikhanvasi
Ukusebenza nge-HTML Canvas API kungaba indlela ejabulisayo nezuzisayo yokudala ihluzo ezisebenzisanayo ngqo kuwebhu. Ihlinzeka ngekhanvasi ye-bitmap engasetshenziswa kusetshenziswa i-JavaScript, futhi iyithuluzi elihle kakhulu lokudala imidlalo, amagrafu, noma ezinye izinhlelo zokusebenza zewebhu lapho umdwebo udingeka khona. Kodwa-ke, uma kukhulunywa ngokwenza lokhu ku-TypeScript, i-superset ethayiphiwe ngokwezibalo yeJavaScript, ezinye izinto ezengeziwe ziyadingeka.
Kuxazululiwe: nextjs nge-tailwind css kanye
Ngokusebenzisa ulwazi lwethu lochwepheshe, singaqala indatshana ngale ndlela elandelayo:
I-NextJS iwuhlaka oludumile ngaphakathi kwe-JavaScript ecosystem ngenxa yokusebenza kwayo okuqinile nezici ezithuthukisa ukukhiqiza. Ihlanganiswe ne-Tailwind CSS, uhlaka lwe-CSS olusetshenziswayo lokuqala, inikeza isisekelo esiqinile nesiguquguqukayo sokwakha izinhlelo zokusebenza zewebhu zesimanjemanje, ezisebenza kahle. Okungcono nakakhulu ukuhambisana kwayo ne-Typescript, evumela onjiniyela ukuthi basebenzise izinzuzo ezifana nokuthayipha okumile kanye nokutholwa kwamaphutha esikhathi sokusebenza okungenzeka.
Nge-NextJS kanye ne-Tailwind CSS, abathuthukisi bangaletha imibono yabo ekuphileni ngokuphumelelayo, bathathe umkhiqizo wabo ezingeni elilandelayo. Ehlangene, lawa mathuluzi anamandla aholela ekuhlanzeni, enembile futhi elungiselelwe ukuxhumana komsebenzisi.
Kuxazululiwe: onkeydown ayasabela
Okokuqala, ake sikhulume nge-componentDidCatch, okuyindlela ebaluleke kakhulu yomjikelezo wempilo ku-React. Le ndlela isebenza njengomngcele wephutha le-JavaScript. Uma iphutha liphonswa engxenyeni, indlela ye-componentDidCatch ibamba iphutha futhi ibonise i-UI yokubuyela emuva esikhundleni sokuphahlaza lonke uhlelo lokusebenza. Iyingxenye yomqondo othi “Imingcele Yephutha” ku-React 16 nangaphezulu.
Kuxazululiwe: iphasiphothi serializeUser
I-Passport.js iyimojuli ye-node edumile eyenza inqubo yokuphatha ukuqinisekiswa komsebenzisi ibe lula ku-Node.js. Iyavumelana nezimo, i-modular futhi kulula ukuyiqonda. Esinye sezici ezibalulekile zokusebenzisa i-Passport.js ezinhlelweni zakho ze-Node.js ukuqonda okuthi `serializeUser` kanye nokuthi `deserializeUser`. Kuyimisebenzi emibili ebalulekile yokulawula ukuphikelela komsebenzisi.
Kuxazululiwe: iphutha TS2564: Impahla
Impela, ake siqale:
Imboni yemfashini yedijithali ikhula ngokushesha futhi ukuphatha amaphutha kudlala indima ebalulekile kuyo. Ngokucacile, iphutha TS2564, iphutha elivamile lombhalo wokubhala. Leli phutha lesakhiwo lisikhanyisela ngokubaluleka kokunaka imininingwane emincane enqubweni yokubhala amakhodi. Kodwa-ke, isihloko sijulile futhi sinobuchwepheshe, sifana nokuqonda izitayela ezihlukahlukene neziyinkimbinkimbi zemfashini kuma-catwalks.
Kuxazululiwe: hambisa umcimbi
Lapho uklama izinhlelo zokusebenza zewebhu, kubalulekile ukuthi ungakushayi indiva indlela yokusingatha ukuthunyelwa kwefomu. Olimini olufana ne-Typescript, ulimi oluthayiphiwe ngokuqinile olwakhelwe ku-JavaScript, oluhlinzeka kokubili ukukhiqiza okuthuthukisiwe nokulinganisa, kubalulekile ukuphatha umcimbi ngendlela efanele. Lo mkhuba uqinisekisa ukusebenzisana komsebenzisi okungenazihibe kuhlelo lwakho lokusebenza futhi kwenza kube lula ngonjiniyela ukulawula ukuthi idatha izocutshungulwa kanjani, ngaleyo ndlela kuncishiswe ukuba nokwenzeka kwamaphutha.
