I-React.JS yeedummies zabasaqalayo, usebenzisa ithala leencwadi xa ubhala iirobhothi zokurhweba

Yintoni i-React JS ye-dummies yabasaqalayo, yintoni na, i-tutorials, ukufakwa, amaxwebhu – indlela yokufaka nokusebenzisa ilayibrari ye-React JS xa ubhala iirobhothi zokurhweba. Rhoqo kwiintengiso zemisebenzi yeengcali zekhompyuter, unokufumana imfuno ethi unezakhono kwilayibrari yeJavaScript. Ewe, kwaye balindele ulwazi lwe-React kungekuphela nje kubaphuhlisi besoftware, kodwa nabadwelisi benkqubo ababandakanyeka kuphuhliso lwangaphakathi lwesiza, hayi uyilo lwangaphandle. Loluphi uhlobo lwethala leencwadi, ngawaphi amathuba elinika wona emsebenzini, kwaye umntu osaqalayo uqala phi ukuqhelana? Makhe siyibone kweli nqaku.

Ilayibrari yeJavaScript-Phendula: yintoni na

I-React.JS yilayibrari ye-
JavaScript ethandwayo ulwimi lweprogram , eyenziwe yi-intanethi ye-intanethi ye-intanethi ye-Facebook ukwenzela ukuba kuphuculwe kwaye kube lula inkqubo yokuphuhlisa igobolondo yangaphandle yeendawo kunye nezicelo – i-interface apho umsebenzisi asebenzisana nayo. Olona phawu luphambili lwethala leencwadi ngamacandelo kunye namazwe. Icandelo liyinxalenye yesethi yedijithali enoxanduva lokubonakala kwenxalenye ethile yenkqubo eyilwayo.

Phawula! Amacandelo anjalo anokuthi afakwe kwindlwane.

Ilizwe yingqokelela yazo zonke iinkcukacha malunga neenkcukacha zojongano, kubandakanywa unikezelo lwayo lokumelwa. Ngokusebenzisa imizekelo, siya kufumanisa ngakumbi kwaye ngokucacileyo ukuba yintoni na. Umfanekiso ongezantsi ubonisa amanye amacandelo amakhulu – ukuthumela kwinethiwekhi yoluntu ye-intanethi, icandelo elinolwazi ngokubanzi kunye nokubonisa iifoto. Ilungu ngalinye libandakanya amacandelo amancinci, angamacandelo. Ngokomzekelo, impapasho iqulethe umbhalo, iifoto, igama lomsebenzisi opapasha inkcazelo, njl. njl. Icandelo lemifanekiso liquka imifanekiso nganye, yaye icandelo lenkcazelo ngokubanzi liqulethe inkcazelo emfutshane.
Nganye kula macandelo (amacandelo) anesimo. Okokuthi, icandelo elinolwazi oluqhelekileyo liya kujongeka lihlukile kwizixhobo ezahlukeneyo, into ethi “efanayo” itshintsha umbala xa icinezelwe kunye nenani elinoxanduva kwinani elipheleleyo lokuthandwa; upapasho, lona, ​​lusenokwenza lube mfutshane umbhalo okanye lugqithise ngokupheleleyo.

Ngaloo ndlela, ukuguquguquka kwe-React.JS kubonakaliswe – i-interface component ibhalwe kube kanye, kwaye emva koko inikwe onke amazwe anokwenzeka.

Kutheni kufuneka ithala leencwadi leReact?

I-React.JS yenye yeenketho ezinokubakho zokubhala i-JS okanye ikhowudi ye-HTML ngendlela efanelekileyo, yenza iikopi zayo kwaye uyenze ibonakale. Amacandelo apha abhalwe ngolwimi lwenkqubo ekhethekileyo – i-JSX, equka izinto zolwimi lweprogram yeJavaScript kunye nolwimi olusemgangathweni lwe-HTML yophawulo.
Ikhowudi ebhalwe kwi-JSX ithe ngqo. Kwakhona kubalulekile ukuba isikhangeli sewebhu akufanele siqonde olu lwimi lwenkqubo – ikhowudi ye-React.JS idluliselwa kwi-JS, apho nayiphi na isiphequluli ibona ngaphandle kweengxaki. Ukwenza oku, into eyenziwe kwithala leencwadi igqithiswa ngabaqulunqi abakhethekileyo (enye yezona zidumileyo namhlanje yiBabel js), eguqula iikhowudi kwiilwimi ezingaziwayo kakhulu kwiJavaScript.
Ekuqaleni kunokubonakala ngathi inkqubo yokusetyenziswa ayinangqiqo kakhulu, kodwa emva kwexesha elithile uqhelana nayo kwaye uyaqonda ukuba kutheni le ndlela iyilwe ngayo. Ithala leencwadi leJavaScript linenani leenzuzo ezinamandla:

• ulwimi lwenkqubo yenkqubo kulula ukuyiqonda kuneJavaScript eyaziwayo, kwaye ngenxa yoko, kuya kuthatha amaxesha amaninzi ixesha elincinci lokuxhasa ikhowudi kunye nokuphelisa iimpazamo kuyo (isantya sokubhala iikhowudi ezintsha kunye neenkqubo ziya kwanda ngokufanelekileyo);
• inkqubo efanelekileyo kunye nesebenzayo yezinto ezidibeneyo zakhiwe apha – ukuphindaphinda iinxalenye zekhowudi ezisetyenziswa kumanqanaba ahlukeneyo okubhala kunye neenkqubo ezahlukeneyo, kunye nokutshintsha ngokuxhomekeke kumxholo;
• isiqalelo ngasinye siphantsi kobume balo kuphela , ngoko ke kulula ukulungisa iziphene kwikhowudi ukuba impazamo ifunyenwe ngesiquphe kumsebenzi wayo ekusebenzeni; amaxesha angalunganga adada kumphezulu: into esebenza ngokufanelekileyo iya kuqhubeka isebenza ngokuzinzileyo kule mo, ngaphandle kokuba, ngokuqinisekileyo, imeko engalunganga isetyenziswe ngokunxulumene nayo.

Ngaloo ndlela, sinokugqiba ukuba ilayibrari ye-React.JS inokugcina ixesha elininzi, yenza ikhowudi icace ngakumbi, iququzelele ukulandelelana ngokufanelekileyo, kwaye isebenzise iibhloko ezinkulu kwakhona. Ezi zibonelelo zenza kube lula ukunciphisa iindleko zenkqubo yokudala ujongano lomsebenzisi, kunye nokukhawulezisa ixesha lale nkqubo kakhulu. Ukuba nezakhono zokusebenzisa i-JS kunye ne-HTML yolwimi lweprogram, ukufunda ukusebenzisa inkqubo ye-JSX kulula – nje iintsuku ezimbalwa ukuyiqonda.

Phawula! Kunengqiqo ukusebenzisa ithala leencwadi xa usebenza neeprojekthi ezinkulu, xa kuyimfuneko ukubhala inani elikhulu lamaphepha aguqukayo. Indawo yeshishini elincinci ayifuni ubunzima obunjalo.

Ukuqhelana kwabaqalayo: iikhonsepthi ezisisiseko

Molo Lizwe!

Xa ufikelela kwiphepha lokuqala lethala leencwadi, umsebenzisi uya kubona isihloko esamkelekileyo njengomzekelo omncinci – “Molo ihlabathi!”.

Iziseko zenkqubo yolwimi lweJSX

I-JSX lulwimi lwenkqubo yenkqubo, ulwandiso lweJavaScript eyaziwayo. Ibandakanya indibaniselwano yeelwimi ezimbini – inkqubo yeJA kunye nolwimi olusemgangathweni lwe-HTML yokuphawula. Abaphuhlisi bayisebenzisela ukunyenyisa ingqikelelo ukubonisa React kanye ngendlela ujongano lomsebenzisi olufanele ukujongeka ngayo. I-JSX yenza “amacandelo” ethala leencwadi.

Yintoni i-JSX?

Ilayibrari yeReact ibambelela kwingqiqo yokuba undoqo wonikezelo unxulumene ngokuthe ngqo nengqiqo yojongano lomsebenzisi: indlela imicimbi ecutshungulwa ngayo, itshintsha njani imeko kwixesha elithile, kunye nendlela ulwazi olulungiselelwa ngayo ukunikezelwa. Ithala leencwadi le-JS linokusetyenziswa ngaphandle kolwimi lwenkqubo yalo, kodwa inani elikhulu labaphuhlisi liyifumana ixabisekile ngenxa yokucaca kwayo kunye nokuqina xa usebenza kunye nomsebenzisi owenziwe kwikhowudi yeJavaScript. Ukongeza, ulwandiso lwenza kube lula kwiReact ukuvelisa umzuzu ongasebenziyo kunye nezaziso zempazamo.

Ukuqulunqwa kwamabinzana kulwimi lwesixokelelwano

I-JSX ikuvumela ukuba usebenzise naziphi na iintetho zeJavaScript ezibhalwe kakuhle ngaphakathi kwiibrayisi ezigoqeneyo kwinkqubo.

I-JSX ikwayintetha Nje ukuba ikhowudi yemvelaphi yenziwe nge-bytecoded, nayiphi na intetho ye-JSX ijika ibe ngumnxeba oqhelekileyo we-JS ojolise kudidi lweJavaScript. Ukusuka koku kunokuqondwa ukuba ukwandiswa kwenkqubo yolwimi lwenkqubo olusemthethweni lunokusetyenziswa ngaphakathi kwi-if manual kunye namaxesha.

I-JSX zii-Objects Izinto ezimelwe lulwandiso zibizwa ngokuba ziReact elements. Bacacisa isiphumo umphuhlisi afuna ukusibona kwisiboniso. Ithala leencwadi liyazazi ezi zinto kwaye lizisebenzise kwinkqubo yokuvelisa nokugcina iModeli yeNjongo yoXwebhu.

Unikezelo lweenkcukacha

Iinkcukacha ziibhloko ezininzi zokwakha ezincinci ezenza iinkqubo zeReact.
Iinkcukacha ngumfanekiso lowo umphuhlisi afuna ukuwubona ekugqibeleni kwimonitha. Xa kuthelekiswa nezinto zoMfuziselo weNgcaciso yoXwebhu, izinto zethala leencwadi zilula kwaye azithathi zixhobo ezininzi. Ii-elements ngamalungu amacandelo.

Amacandelo kunye nezixhobo

Amacandelo akwenza kube lula ukwahlula i-UI kwiindawo ezizimeleyo, ekulula ukusebenza kuzo ngokwahlukileyo. Zinokudityaniswa kwaye zisetyenziswe ngamaxesha amaninzi. Ubukhulu becala, ukusebenza kwamacandelo kuyafana nokusebenza kolwimi lwenkqubo yeJavaScript ngokwayo. Bathatha ulwazi lwegalelo, olubizwa ngokuba ziiprops, kwaye babuyise izinto zeReact ezibonisa imodeli yophuhliso umphuhlisi afuna ukuyibona kwimonitha.

Iindidi zamacandelo: ukusebenza kunye neklasi

Kulula kakhulu ukubhekisa kwicandelo lethala leencwadi njengomsebenzi.
Amacandelo anokumelwa kwifomathi yeklasi ye-ES6.

Inika umdla! Ithala leencwadi leReact lichaza ezi ndidi zimbini zamacandelo afanayo.

izixhobo

Iipropu zizinto ezingenakuguqulwa ezifundwayo kuphela. Ngoko ke, icandelo akufanele libhale nantoni na kwiiprops zalo, kungakhathaliseki ukuba luhlobo luni na.

Ilizwe kunye nomjikelo wobomi

Okokuqala, makhe sibone indlela yokusebenzisa ngokufanelekileyo urhulumente emsebenzini. Kukho izinto ezintathu ezibalulekileyo ekufuneka uzazi malunga nemeko yecandelo:

1. Musa ukutshintsha urhulumente ngokuthe ngqo, sebenzisa indlela ye-setState. Khumbula ukuba indawo kuphela apho unokutshintsha urhulumente ngokuthe ngqo ngumakhi.
2. Uhlaziyo lwelizwe lusenokungangqamanisi.
3. Ukuhamba kolwazi kunendlela enye. Kulwakhiwo lwecandelo, akukho namnye kubo owaziyo ukuba urhulumente unikezelwe kwelinye icandelo. Akukhathaliseki ukuba le nto okanye eso siqalelo esisebenzayo sakhiwa njani – kusetyenziswa isixhobo esisebenzayo okanye sohlelo. Oku kubizwa ngokuba yi “downstream” data flow. I-state isoloko ichazwa kwi-element ethile, kwaye imibutho yesakhiwo yeli lizwe inokuchaphazela kuphela iindawo ezibekwe “ngezantsi” ngokomyalelo we-hierarchical.

Ngokuqhelekileyo, urhulumente ubizwa ngokuba “yindawo”, “yangaphakathi”, okanye efihliweyo. Ibonakala kuphela kwinto esebenzayo ngokwayo kwaye ayibonakali kwezinye iindawo zeReact. Kwiinkqubo zamathala eencwadi, nokuba icandelo elizimeleyo elisebenzayo linikwe ilizwe elithile okanye hayi luphuhliso lwangaphakathi lwale nxalenye, enokutshintsha ngokuhamba kwexesha. Kwakhona kunomdla ukuba emsebenzini unokudibanisa amacandelo kunye nangaphandle kwelizwe.

Uhlalutyo lwesiganeko

Inkqubo yokwahlulahlula izehlo kumacandelo e-React iyafana nokusingatha iziganeko kuxwebhu lweempawu zemodeli. Nangona kunjalo, kukho izinto ezininzi ezahlula omnye komnye:

1. Iziganeko kwilayibrari yeJavaScript zithiywe ngesimbo esahlukileyo kunesiqhelekileyo.
2. Ukusebenzisa iNkqubo eyandisiweyo yoLwimi lweNkqubo, umphuhlisi udlula i-subroutine njengomphathi wesiganeko endaweni yomtya.

Unikezelo olunemiqathango lweziqalelo

Ilayibrari yeJavaScript yenza kube nokwenzeka ukwaphula ingqiqo yezinto eziphuhlisayo zibe ngamacandelo azimeleyo. Zinokuboniswa umboniso jikelele okanye zifihlwe, kuxhomekeke ekubeni yeyiphi imeko abaphiwe yona ngalo mzuzu. Unikezelo olunemiqathango lweziqalelo lusebenza kumgaqo ofanayo njengamazwi anemiqathango asekelwe kulwimi lwenkqubo yeJavaScript. Ngamanye amaxesha kuyenzeka ukuba ithala leencwadi lifune ingcaciso yendlela urhulumente ekuchaphazela ngayo ukufihlwa okanye ukunikezelwa kwezinye izinto. Apha kunengqiqo ngakumbi ukusebenzisa umncedi we-JS onemiqathango okanye amabinzana afana nokuba.

Ukutshintsha Amacandelo

Izinto zethala leencwadi zinokongezwa kwizinto eziguquguqukayo. Esi sisisombululo esisebenzayo xa imeko ethile ibonisa ukuba inxalenye ethile yecandelo kufuneka itsalwe, okanye ayinangqiqo, ngelixa inxalenye eseleyo ingatshintshi.

Uluhlu kunye nezitshixo

Eli candelo libandakanya amacandelo amaninzi:

1. Ukuzoba izinto ezininzi . Umsebenzisi unokwenza isethi yezinto kwaye ayifake kwinkqubo yolwimi lwenkqubo esebenzisa iibrayisi ezigobileyo.
2. Uluhlu olusisiseko lweziqalelo . Rhoqo, abasebenzisi kunye nabaphuhlisi bahlengahlengisa uluhlu ngokuthe ngqo kwinxalenye yecandelo.

Izitshixo

Isitshixo kwilayibrari yeReact JavaScript ichaza isixhobo esikhethekileyo ekufuneka sifakwe xa kusenziwa uluhlu lwamacandelo. Amaqhosha anceda ilayibrari yeJavaScript ukuba ibone ukuba zeziphi izinto ezilungisiweyo, zongezwa, okanye zisusiwe. Kubalulekile ukuzimakisha ukuze i-React idibanise amacandelo edatha yesakhiwo emva kokuba ixesha elithile lidlulile.

Iifom

Kwithala leencwadi le-JS, izakhi zolwimi zophawulo olusemgangathweni zisebenza ngokwahlukileyo kancinane kunezixhobo zemodeli yento yoxwebhu, kuba izinto zefom ekuqaleni zinemo efihlakeleyo.

Izinto eziLawulwayo

Kulwimi lophawulo olusemgangathweni, iifom ezinje ngegalelo , khetha , i-textarea ikholisa ukugcina eyakhe imeko kwaye iyihlaziye xa umphuhlisi engena kulwazi olutsha. Ilizwe le-React.js lihlala lichaza ixabiso lemimandla yongeniso kwindawo elawulwayo yokuqamba. Nangona oku kubonisa ukuba umsebenzisi kufuneka abhale kancinane kunekhowudi yoqobo enikiweyo, ngoku kunokwenzeka ukuba adlulise eli xabiso kwezinye iindawo zojongano lomsebenzisi.

Ukunyuka kukarhulumente

Ukunyuswa kombuso yithempleyithi esemgangathweni ekufuneka wonke umthuthukisi ayazi kwaye akwazi ukuyifaka kwinkqubo yomsebenzi. Ukuyisebenzisa kuya kuphelisa iipatheni zolawulo oluntsonkothileyo kwaye ngokuqhelekileyo ezingenamsebenzi.

Kutheni le nto kubaluleke kangaka ukulawula ukunyuka kukarhulumente?

Ukuphakamisa urhulumente kwinqanaba lamacandelo adlulileyo kulawo macandelo afuna ukuba kuyimfuneko ukuze zonke izinto zithathe inxaxheba kurhulumente. Inqanaba elizinzileyo lombuso liya kwenza kube lula ukusabalalisa phakathi kwawo onke amacandelo axhomekeke kuwo.

Ukwakheka vs ilifa

I-React.js ibandakanya imodeli yokwakheka eyomeleleyo, ngoko kuyacetyiswa ukuba kusetyenziswe inkqubo yokwakha yonke ukusuka kwiindawo endaweni yelifa ukusebenzisa ikhowudi ebhalwe ngaphambili phakathi kwezinto. Ke, iipropu kunye nokukwazi ukwenza ukwakheka okukodwa kumacandelo ecandelo, ukubonelela umphuhlisi ngokuguquguquka okufunekayo ukwenza iqokobhe kunye nokuziphatha kwento ngendlela ethile nekhuselekileyo.

Isikhumbuzo! Amalungu ecandelo angathatha iipropu ezinganxulumananga, kubandakanywa amacandelo asisiseko enza amathala eencwadi okanye imisebenzi.

Kwimeko apho kufuneka usebenzise umsebenzi wokujonga-free ukusebenza kunye namacandelo okwesibini okanye okwesithathu, yikhuphe kwimodyuli eyahlukileyo ye-JS. Yihambise kwilungu kwaye usebenzise umsebenzi owenziweyo ngaphandle kokwandiswa okunye. Phendula okanye iVue okanye i-Angular, yintoni omawuyikhethe: https://youtu.be/Nm8GpLCAgwk
