Tere tulemast! Kui sa oled siin, siis oled t\u00f5en\u00e4oliselt algav front-end arendaja<\/a> kes soovivad saada s\u00fcgavamat arusaamist React<\/a> v\u00f5i v\u00f5ib-olla isegi kogenud professionaal, kes harjutab p\u00f5hit\u00f5desid. See artikkel on teie teejuht k\u00f5igele React eluts\u00fckkel<\/strong> - see on selle n\u00e4iliselt pimeda metsa taskulamp, nii et hoidke kinni ja olge valmis alustama seda intrigeerivat teekonda.<\/p>\n

\u00dclevaade React eluts\u00fcklist<\/h2>\n

Komponentide eluts\u00fckli m\u00f5iste tarkvaraarendus<\/a> on sarnane kasvu- ja langusetappidega, mida elusorganismid l\u00e4bivad. Samamoodi l\u00e4bivad teie komponendid Reacts mitu erinevat faasi - nad s\u00fcnnivad (paigaldatakse), kasvavad (uuendatakse) ja l\u00f5puks surevad (eemaldatakse). Nende etappide m\u00f5istmine aitab saavutada paremat j\u00f5udluse optimeerimist ja suurendab teie v\u00f5imet tegeleda t\u00f5husalt vigadega.<\/p>\n

Siin on neli olulist sammu, mis on seotud komponendi eluts\u00fckkel<\/strong>:<\/p>\n

    \n
  1. Initsialiseerimine: Selles etapis seadistame riigi ja rekvisiidid.<\/li>\n
  2. Paigaldamine: Etapp, kus meie Reaktsioonikomponent<\/strong> kinnitab end DOMile.<\/li>\n
  3. Uuendamine: K\u00f5ik hilisemad muudatused, mis toimuvad riikidelt v\u00f5i rekvisiitidelt saadud uuenduste t\u00f5ttu, kuuluvad selle etapi alla.<\/li>\n
  4. Mahakandmine: The l\u00f5ppfaas<\/strong> kus komponent on eemaldatud DOMist<\/strong>.
    \nNeid etappe saab visualiseerida sellise eluts\u00fckli diagrammi abil nagu see siin.<\/li>\n<\/ol>\n

    J\u00e4rgmistes osades k\u00e4sitleme iga faasi eraldi koos reaalsete n\u00e4idetega, et parandada arusaamist - olge valmis s\u00fcgavale sukelduma j\u00e4rgmistesse teemadesse meetodid<\/strong> nagu componentDidMount, getDerivedStateFromProps, render, componentDidUpdate jne. Nende m\u00f5istete lahtim\u00f5testamine natuke kaupa annab teile teadmisi, mis t\u00f5esti muutuvad praktilisteks arusaamadeks tulevaste projektide jaoks, mis h\u00f5lmavad reactjs eluts\u00fcklit!<\/p>\n

    Paigaldamise faas<\/h2>\n

    The paigaldusfaas<\/strong> aastal React eluts\u00fckkel<\/strong> esindab seisundit, kus meie komponendid ehitatakse ja sisestatakse esimest korda DOM-i. See etapp koosneb neljast olulisest etapist meetodid<\/strong>: konstruktor, getDerivedStateFromProps, render ja componentDidMount.<\/p>\n

    Konstruktor<\/h2>\n

    The konstruktori meetod<\/strong> on meie klassip\u00f5histe komponentide loomise esimene samm. M\u00f5elge sellele kui oma komponendi \"sissep\u00e4\u00e4supiletile\", et React eluts\u00fckkel<\/strong>. Konstruktori funktsioon tegeleb tavaliselt peamiselt kahe asjaga:
    \n1. Kohaliku oleku initsialiseerimine.
    \n2. S\u00fcndmuse k\u00e4sitsemise meetodite sidumine.
    \nSisuliselt on see koht, kus te kehtestate oma vaikimisi oleku ja defineerite k\u00f5ik komponendi jaoks vajalikud instantsi omadused.<\/p>\n

    GetDerivedStateFromProps<\/h2>\n

    J\u00e4rgmine meie teekond l\u00e4bi paigaldusfaas<\/strong> on getDerivedStateFromProps. See staatiline meetod <\/strong>sillutas oma teed React 16.3. See v\u00f5imaldab us<\/a> et s\u00fcnkroonida komponendi sisemine olek koos muudatustega, mis kajastuvad vanemkomponendi poolt antud rekvisiitide kaudu enne renderdamist. Kasutage seda s\u00e4\u00e4stlikult! Liigne kasutamine v\u00f5ib tekitada keerukust meie s\u00fcnkroonimisprotsessi k\u00f5rvalm\u00f5jude t\u00f5ttu.<\/p>\n

    \"\"<\/a><\/p>\n

    Renderda<\/h2>\n

    Olles seadistanud k\u00f5ik vajaliku, j\u00e4tkame renderdamisega. See puhas meetod annab JSX-i v\u00f5i null, kui midagi ei ole vaja renderdada - see on sisuliselt see, kus kogu teie m\u00e4rgistus visandatakse!<\/p>\n

    Kriitiline aspekt? \u00c4rge p\u00f5hjustage siin k\u00f5rvalm\u00f5jusid, kuna render v\u00f5ib k\u00e4ivitada mitu korda, mille tulemuseks on soovimatuid m\u00f5jusid ja j\u00f5udlusprobleeme!<\/p>\n

    ComponentDidMount<\/h2>\n

    Ja voil\u00e0! Kui meie \"m\u00e4rgistus\" renderist on edukalt DOM-i lisatud, tuleb componentDidMount. N\u00fc\u00fcd see funktsionaalne komponent<\/strong> poiss veendub, et iga vajalik andmed<\/a> mida vajate p\u00e4rast renderdamist, saab laadida t\u00f5husalt, ilma et see m\u00f5jutaks liiga palju j\u00f5udlust - tavaliselt on see ideaalne koht as\u00fcnkroonsete noppimise p\u00e4ringute jaoks, staatuse uuendamiseks l\u00e4bi API<\/a> vastused v\u00f5i ajamite seadmine.<\/p>\n

    Kuid pidage meeles, et as\u00fcnkroonsete protsesside kontrolli all hoidmine aitab kaasa sujuvate kasutajakogemuste tagamisele!<\/p>\n

    Sellega l\u00f5petame meie ekskursiooni React's paigaldusfaas<\/strong>-\u00fclimalt oluline periood jooksul react komponendi eluts\u00fckkel<\/strong> mis sillutab sellise tervikliku pinnase t\u00f5husaks veebirakendused<\/a> loomine ja haldamine. Sellel p\u00f5neval teekonnal, mis on t\u00e4is konstruktoreid, rekvisiitidest tuletatud seisundeid, massilist renderdamist ja l\u00f5puks didMounti \u00fclesannete t\u00e4itmist p\u00e4rast renderdamist\u2500 kus ootavad ees s\u00fcgavamad m\u00f5isted nagu ajakohastamisetapid<\/strong> & eemaldamine\u2500k\u00f5ik, mis tugevdab veelgi ReactJS-i eluts\u00fckli teadmisi!<\/p>\n

    Ajakohastamise faas<\/h2>\n

    P\u00f5hiline etapp React eluts\u00fckkel <\/strong>on faas \"Uuendamine\". Selle etapi jooksul k\u00e4ivitavad k\u00f5ik muutunud olekud uue kuvamisprotsessi ja v\u00f5ivad viia komponentide uuendamiseni. Siinkohal s\u00fcveneme viie peamise meetodid<\/strong> mis moodustavad selle uuendamise faas<\/strong>: - getDerivedStateFromProps, shouldComponentUpdate, render, getSnapshotBeforeUpdate ja componentDidUpdate. Nende valdamine eluts\u00fckli meetodid<\/strong> react arendajad sageli p\u00fc\u00fcdlevad, tagades seega meie reaktiivsete s\u00fcsteemide sujuvama rakendamise. komponentide uuendused<\/strong>.<\/p>\n

    getDerivedStateFromProps<\/h2>\n

    Nii segadusttekitav, kui selle nimi ka ei tundu, logib see meetod nimelt teie komponendi vanemate omadustest tuletatud uuendatud omadused. GetDerivedStateFromProps n\u00e4ide n\u00e4itab, kuidas see katab v\u00e4ljaspool komponenti toimuvaid arenguid, mis p\u00f5hjustavad v\u00f5imalikku muutust j\u00e4rgmises komponendis komponendi seisund<\/strong> vanema poolt saabuvate uute omaduste alusel. Olge siiski ettevaatlik; selle meetodi kasutamine n\u00f5uab ettevaatust, sest liigne kasutamine v\u00f5ib p\u00f5hjustada raskesti parandatavaid koode ja hooldusprobleeme.
    \nshouldComponentUpdate<\/p>\n

    J\u00e4rgmine on 'shouldComponentUpdate'. See t\u00e4helepanuv\u00e4\u00e4rne m\u00e4ngija annab meile kontrolli, v\u00f5imaldades meil otsustada, kas oleku v\u00f5i rekvisiitide muutused \u00f5igustavad meie komponendi uuesti esitamist. Tavaliselt tagastab see vaikimisi v\u00e4\u00e4rtuse true, mis t\u00e4hendab iga muudatuse puhul taask\u00e4ivitamist. Kui aga on vaja optimeerida j\u00f5udlust v\u00f5i soovite teatud renderdusi s\u00e4\u00e4sta, v\u00f5imaldab see teil siiski return false<\/strong>.<\/p>\n

    renderdada<\/h2>\n

    Arusaadavalt on \".render\" k\u00f5igi eluts\u00fckli keskmes. meetodid<\/strong> nii piltlikult kui ka s\u00f5na otseses m\u00f5ttes. See kujutab seda, mis ilmub ekraanil p\u00e4rast tagasip\u00f6\u00f6rdumist re renderdamine<\/strong> toimub riigi muutumise ajal. Kokkuv\u00f5tlikult \u00f6eldes, kui on vaja uuendada komponendi visuaalset kujutist, mis on tingitud muutustest meie olekus v\u00f5i omaduste suunamisest, tuleb m\u00e4ngu render.<\/p>\n

    getSnapshotBeforeUpdate<\/h2>\n

    Harvemini kasutatav, kuid kasulik meetod on tuntud kui 'getSnapshotBeforeUpdate'. Selle funktsioon seisneb DOMi kohta k\u00e4iva teabe kogumises enne selle v\u00f5imalikku muutmist renderdamise ajal - kasulik, kui s\u00e4ilitatakse selliseid aspekte nagu kerimispositsioon<\/strong> v\u00f5i kasutaja sisusisenditele enne suuri uuendusi.<\/p>\n

    componentDidUpdate<\/h2>\n

    Last but not least vastab 'componentDidUpdate', mida nimetatakse tabavalt nii, kuna see koputab kohe p\u00e4rast uuenduse toimumist post renderdamise toiming ja toimib suurep\u00e4rase ajapikendusena v\u00f5rgup\u00e4ringud<\/strong> v\u00e4listades olukordi, mis viivad \u00fcles render ise v\u00f5i instantsi recreation, mis on m\u00e4rgitud konstruktori all. Tagada v\u00e4ltides l\u00f5putud silmused, samas seadistades riigid ette valvata v\u00f5imalike l\u00f5kse.
    \nNende probleemide valgustamisel meetodid<\/strong> \u00fcksikasjad oleme l\u00e4binud ajal reactjs eluts\u00fckli \"uuendamise\" faasi aitaks rakendada parandusi vaevata, lisades samal ajal keerulisi operatsioone suurendades vilumust seel\u00e4bi eksponentsiaalselt muutes kodeerimine mugav!<\/p>\n

    Mahakandmise faas<\/h2>\n

    Kuna me liigume edasi meie uurimisel vastukomponent<\/strong> osa React eluts\u00fckkel<\/strong>, on aeg s\u00fcveneda samav\u00f5rd kriitilisse faasi - see on Mahakandmise faas<\/strong>. See on koht, kus komponendid eemaldatakse dokumendiobjektimudelist (DOM), mis on sageli t\u00e4helepanuta j\u00e4etud, kuid siiski h\u00e4davajalik.<\/p>\n

    componentWillUnmount<\/h2>\n

    Selleks, et sobivalt h\u00fcvasti j\u00e4tta, pakub React meile \u00fche viimase meetodi: componentWillUnmount. Selle kasutamine eluts\u00fckli meetod<\/strong> on oluline nii optimeerimiseks kui ka t\u00fc\u00fctute vigade v\u00e4ltimiseks.<\/p>\n

    Oma lihtsaimal kujul t\u00e4idab componentWillUnmount j\u00e4rgmist renderdamismeetod<\/strong> vahetult enne komponendi lahti\u00fchendamist ja hilisemat h\u00e4vitamist. M\u00f5elge selle meetodi v\u00e4\u00e4rtuslikule kasulikkusele; see on teie viimane v\u00f5imalus siduda lahtised otsad enne komponendile h\u00fcvasti j\u00e4tmist.<\/p>\n

    V\u00f5ib esineda jooksvaid v\u00f5rgup\u00e4ringud<\/strong>, aktiivsed taimerid v\u00f5i tellimused, mille olete algatanud komponendi eluts\u00fckli jooksul. N\u00fc\u00fcd, kui me astume nende komponentide olematuks saatmise \u00e4\u00e4rele, muutub teie vastutuseks nende k\u00e4imasolevate toimingute t\u00fchistamine. Selle tegemata j\u00e4tmine toob kaasa m\u00e4lu lekke, mis v\u00f5ib p\u00f5hjustada teie rakenduse halba k\u00e4itumist v\u00f5i t\u00e4ielikku eba\u00f5nnestumist.<\/p>\n

    N\u00fc\u00fcd, kui te olete tuttav componentWillUnmount'i tavap\u00e4raste kasutusv\u00f5imalustega, tasub m\u00e4rkida ka seda, mida selle meetodi raames ei tohi teha. Peamiselt pidage meeles, et te ei saa siin m\u00e4\u00e4rata olekut, sest kui komponendi instants siseneb lahti\u00fchendamise faas<\/strong>, siis ei saa seda tagasi tuua.<\/p>\n

    Seega l\u00f5peb meie uurimus komponendiWillUnmount ja seega ka \"lahti\u00fchendamise\" faasi kohta reacti ja komponendi eluts\u00fckkel<\/strong>. Need kontseptsioonid esindavad mitmeid t\u00fckke, et juhtida t\u00f5husalt komponentide eluea haldamist: mitte ainult teadmine, miks neid samme on vaja t\u00e4ita, vaid ka arusaamine, kuidas need sobivad kokku suuremates kontekstides, nagu j\u00f5udluse optimeerimine ja vigade v\u00e4ltimine.<\/p>\n

    Funktsiooni konverteerimine klassiks<\/h2>\n

    ReactJS annab teile v\u00f5imaluse kasutada oma komponentide kirjutamisel kas funktsioone v\u00f5i klasse. Siiski v\u00f5ib olla olukordi, kus teil oleks m\u00f5ttekam funktsioonist klassi komponendi teha. See protsess v\u00f5ib alguses tunduda hirmutav, eriti kui te alles tutvute reageeri eluts\u00fckkel<\/strong>.
    \nS\u00fcveneme n\u00fc\u00fcd s\u00fcgavamalt ja anal\u00fc\u00fcsime selle \u00fcleminekuga seotud samme.<\/p>\n

      \n
    1. Loo ES6 klass: Esimene samm h\u00f5lmab ES6 klassi loomist, mis laiendab React.Component. Huvitav on see, et nii funktsiooni- kui ka klassikomponendid saavad ReactJS-is esitada kasutajaliidese kirjeldusi, mis on s\u00fcnon\u00fc\u00fcmne funktsioonide m\u00e4\u00e4ratlemisega.<\/li>\n
    2. Integreerige endise funktsiooni keha: J\u00e4rgmisena sisestage oma renderdamisloogika (varem kogu oma funktsiooni keha) uude meetodisse nimega render(), mis asub teie v\u00e4rskelt loodud klassi sees:<\/li>\n
    3. Rekvisiitide punktid: M\u00e4letate rekvisiite, millele viidatakse otse argumendina teie algses funktsioonis? N\u00fc\u00fcd tuleks neile p\u00e4\u00e4seda ligi this.props'i kaudu k\u00f5igis mittestaatilistes funktsioonides. meetodid<\/strong> teie uue klassi kohta.<\/li>\n<\/ol>\n

      Eelk\u00f5ige on nende sammude eesm\u00e4rk ainult aidata alustada konverteerimist funktsionaalsed komponendid<\/strong> mis on seotud reageeri eluts\u00fckkel<\/strong> samav\u00e4\u00e4rseteks klassideks. J\u00e4tkake harjutamist, kuni olete harjunud kasutama m\u00f5lemat l\u00e4henemist vaheldumisi, l\u00e4htudes projekt<\/a> n\u00f5uded ja isiklikud eelistused!<\/p>\n

      J\u00e4tkake \u00f5ppimist ja uurimist, sest reactjs eluts\u00fckli omandamine v\u00f5tab aega ja praktilisi kogemusi! Head kodeerimist!<\/p>\n

      Kohaliku oleku lisamine klassile<\/h2>\n

      Valdkonnas React arendus<\/a>, kohalik riik on \u00fcks lahutamatuid aspekte. See element, mida m\u00f5istetakse p\u00f5hjalikult kui \"seisundit\", m\u00f5jutab komponentide esitusviisi ja k\u00e4itumist. Teatud komponendid teie rakenduses on olekuga ja peavad s\u00e4ilitama, muutma v\u00f5i j\u00e4lgima teatud t\u00fc\u00fcpi teavet, mis kuulub ainult neile - seega nende \"kohalik olek\".<\/p>\n

      Kohaliku riigi roll<\/h2>\n

      Komponendi kohalik riik kontrollib l\u00f5ppkokkuv\u00f5ttes ainult selle sisemist tegevust. N\u00e4iteks selle m\u00e4\u00e4ramine, kas kasutaja on teie rakenduses kl\u00f5psanud rippmen\u00fc\u00fcs, v\u00f5ib toimuda lokaalse oleku abil - seda teadmist ei pea jagama ega muutma \u00fckski teine rakenduses olev komponent.<\/p>\n

      Kuidas lisada kohalik riik<\/h2>\n

      Kuidas siis lisada see nn. kohalik olek klassi sisse reageeri eluts\u00fckkel<\/strong>? Siin on lihtne protseduur:<\/p>\n

        \n
      1. Seadistage sisse algseisund<\/strong> lisades t\u00e4iendava klassi konstruktori, mis omistab klassile algseisund<\/strong>.<\/li>\n
      2. Initsialiseerige see klassi loomisel m\u00f5ne objektiga.<\/li>\n<\/ol>\n

        Kui p\u00f6\u00f6rate nendele sammudele ja tehnikatele hoolikalt t\u00e4helepanu, saate sujuvalt integreerida 'reageeri eluts\u00fckkel<\/strong>\u2018 meetodid<\/strong> teie t\u00f6\u00f6voogudes, h\u00f5lbustades teekonda v\u00e4ga d\u00fcnaamiliste rakenduste vormimise suunas, millel on suurep\u00e4rased kasutajakontaktid.
        \nRakendamine kohaliku riigi on keskse t\u00e4htsusega kontrolli komponent k\u00e4itumise erinevates segmentides eluts\u00fckli reactjs - eriti ajal paigaldamine v\u00f5i uuendamine etappide kus komponent ei mount ja getDerivedStateFromProps tulevad m\u00e4ngu oluliselt.<\/p>\n

        \u00dcldiselt m\u00e4ngib olulist rolli teadmine, kuidas kohalikke riike t\u00f5husalt luua ja k\u00e4sitleda, kui navigeeritakse l\u00e4bi k\u00f5igi etappide, mis on esindatud t\u00fc\u00fcpilises React eluts\u00fckkel<\/strong> diagrammi, mis annab arendajatele suurema kontrolli komponentide renderdamise ja uuendusp\u00f5hise interaktsiooni \u00fcle. Seega ei ole teie rakendused mitte ainult interaktiivsed, vaid ka intuitiivsed nii programmeerija kui ka l\u00f5ppkasutaja seisukohast.<\/p>\n

        Kaasamine eluts\u00fckli meetodid<\/strong> klassiks Reacts on oluline osa sellest, kuidas komponent k\u00e4itub veebilehe eluea jooksul. See protsess muutub veelgi olulisemaks, kui meil on olekuga komponendid ja me peame j\u00e4lgima nende oleku muutusi aja jooksul.<\/p>\n

        Alustuseks on kasulik n\u00e4ha neid meetodid<\/strong> v\u00f5tmet\u00e4htsusega verstapostidena, mis kirjeldavad meie komponendi elulugu laiemas perspektiivis.<\/p>\n

        P\u00f5hilised eluts\u00fckli meetodid<\/h2>\n

        React konstruktorid andsid sellele geniaalselt spetsiifilisi eluts\u00fckli meetodid<\/strong> nagu componentDidMount, shouldComponentUpdate ja componentWillUnmount. Need k\u00e4ivituvad erinevate etappide ajal.<\/p>\n

        Nende keeruliste osade m\u00f5istmine v\u00f5ib esialgu tunduda keeruline, kuid \u00e4rge muretsege! Kui need sobivad kokku teie vanas\u00f5naliseks puslepildiks, on teil palju suurem paindlikkus oma reaktsiooniklassi komponentide kujundamisel.<\/p>\n

        Tunnistades komponendi eluts\u00fckli olulisi etappe (n\u00e4iteks paigaldamine, uuendamine ja lahti\u00fchendamine), saate lisav\u00f5imaluse andmevoogude t\u00f5husaks manipuleerimiseks rakenduses.<\/p>\n

        Mis React puhul on endiselt p\u00f5nev, on selle potentsiaalne areng - l\u00f5ppude l\u00f5puks v\u00f5ivad t\u00e4nased keerukused muutuda homseteks parimateks tavadeks. J\u00e4\u00e4ge uudishimulikuks igas etapis reageeri eluts\u00fckkel<\/strong>; see on t\u00f5esti ilus teekond!<\/p>\n

        Riigi \u00f5ige kasutamine<\/h2>\n

        Kui te l\u00e4bite teekonna l\u00e4bi m\u00f5istmise React eluts\u00fckkel<\/strong>, muutub riigi kasutamise valdamine esmat\u00e4htsaks. See asendamatu v\u00f5ime jooksul React eluts\u00fckkel<\/strong> m\u00e4ngib kriitilist rolli teie komponentide andmete haldamisel ja ajakohastamisel.
        \n\"Seisund\" on sisuliselt andmed, mis m\u00f5jutavad renderdamist eri viisidel ja v\u00f5imaldavad d\u00fcnaamilisi muudatusi teie komponendis. Samuti tasub m\u00e4rkida selle erip\u00e4ra; erinevalt Propsist, mis antakse vanemkomponentidelt lapskomponentidele \u00fcle, hallatakse State'i komponendi enda sees.<\/p>\n

          \n
        1. Initsialiseerimine: Kui m\u00e4\u00e4ratlete oma Komponentide klass<\/strong>, on hea tava initsialiseerida olek oma konstruktori meetod<\/strong>.<\/li>\n
        2. Uuendamine: Selle asemel, et muuta this.state otse. React ei pruugi as\u00fcnkroonse olemuse t\u00f5ttu olekut kohe uuendada, seega kasutage alati this.setState().<\/li>\n
        3. Juurdep\u00e4\u00e4s riigile: state: Kasutage lihtsalt this.state, et sellele ligi p\u00e4\u00e4seda v\u00f5i seda lugeda.<\/li>\n<\/ol>\n
