= Kungani i-Firebase Hosting? =
I-Firebase iyinkundla yohlelo lokusebenza ebanzi eyakhelwe kungqalasizinda ye-Google, ngakho-ke inikeza ingqalasizinda evikelekile, esheshayo, yamahhala (izinketho ezikhokhelwayo nazo ziyatholakala kwezinye izinsiza) kanye nendlela elula yokubamba okuqukethwe kwakho ku- izinhlelo zokusebenza zewebhu noma zeselula
== Izici Ezibalulekile Nezinzuzo zesigaba samahhala: ==
- Inikeza isizinda samahhala sangokwezifiso&
SSL(I-SSL inikeza isendlalelo esijwayelekile sokuvikela sokuxhunywa kwe-https
- I-Cloud Firestore: Isizindalwazi esivumelana nezimo nesikakalayo sokuvumelanisa idatha yesikhathi sangempela kuzo zonke izinhlelo zokusebenza zamaklayenti
- Ezinye izici: Imisebenzi Yamafu, Imilayezo Yefu (FCM), Crashlytics, Dynamic Links, Hosting, ML Kit, Storage, Performance Monitoring, Predictions and Test Lab (Ukusebenza nezisetshenziswa zale mikhiqizo zinganyuswa ngokuthenga uhlelo olukhokhelwayo, kodwa amasevisi esigaba samahhala mahle kakhulu. Ukuze ubheke izinhlelo hlola Amanani e-Firebase)
- Ukukala okuzenzakalelayo kwezinsiza
= Izinyathelo zokusingatha iwebhusayithi yakho enamandla ku-Firebase =
== Izidingo ==
**1. I-akhawunti ye-Google**Uma ungenayo i-akhawunti ye-Google, udinga ukuyibhalisela. Ungakwenza lokho ngokuya kokuthi httpsaccounts.google.com/SignUp. **2. I-Node.js kanye ne-npm** Mac/WindowsUngalanda isifaki ku-httpsnodejs.org/en/download/. I-Linux
Landela lezi zinyathelo ezingezansi ukuze ufake i-Node.js:
1. Vula itheminali
2. Qalisa imiyalo elandelayo:
sudo apt-get install curlcurl -sL httpsdeb.nodesource.com/
setup_13.x| sudo bash -sudo apt ukufaka nodejs **Ngisebenzise Qaphela: ** **
setup_13.xngoba ngesikhathi sokufundisa kwakuyinguqulo yakamuva
**13**ungahlola ukukhishwa kwakamuva ngokuya kokuthi httpsnodejs.org/en/
Ukuhlola ukuthi i-Node.js ne-npm zifakwe ngempumelelo yini sebenzisa imiyalo elandelayo, ezokhipha inguqulo efakiwe:
indawo -v
npm -v
**3. I-Firebase-CLI (I-Command-Line InterfaceLawa amathuluzi okuphatha, ukubuka, kanye nokuphakela amaphrojekthi e-Firebase
npm ukufaka -g firebase-amathuluzi
= Isinyathelo 1: Dala iphrojekthi ye-Firebase =
- Iya ku-httpsfirebase.google.com futhi
Ngena ngemvume usuka ekhoneni eliphezulu kwesokudla
- Chofoza
Iya ku-console, kusukela ekhoneni eliphezulu kwesokudla
- Bese uchofoza
Dala iphrojekthi, njengoba kukhonjisiwe ngezansi

5. Cindezela okuthi qhubeka ukuze unike amandla i-Google Analytics kuphrojekthi yakho ye-Firebase (uma ungayifuni bese uhlola ukuze uyikhubaze)
6. Khetha indawo eseduze ye-Google Analytics
7. Chofoza ku-
**Dala iphrojekthi bese ulinda ukuthi ilayishwe. Khona-ke uzobona into efana ngezansi
= Isinyathelo sesi-2: Qalisa ukungena ngemvume kwe-Firebase =
- Vula umugqa womyalo/ukuphela bese udala bese uya kusiqondisi esisha
mkdir my-firebase-projectcd my-firebase-project
2. Ukusingatha iwebhusayithi ku-Firebase ngena ku-firebase usebenzisa umyalo olandelayo. Ngemva kokwenza umyalo iwindi lesiphequluli lizovuleka likucela ukuthi ungene ku-firebase usebenzisa imininingwane yakho ye-Google. Faka imininingwane lapho futhi i-Firebase izongena ngemvume kusistimu yakho
ukungena ngemvume kwe-firebase
= Isinyathelo sesi-3: Qalisa iphrojekthi ye-Firebase kusistimu yakho =
- Manje kufanele siqalise iphrojekthi esiyidalile kukhonsoli ye-Firebase siyifaka ohlelweni. Ukwenza sebenzisa umyalo ongezansi
firebase init
2. Cindezela inkinobho ephansi bese ukhetha
**izinto ezimbili **ngokucindezela inkinobho ethi **ibha yesikhala
- Imisebenzi
- Ukusingatha
Khona-ke
**cindezela u-Enter** ukuze uqhubeke
3. Bese ukhetha
bese ucindezela u-enter
**Sebenzisa iphrojekthi ekhona **
4. Cindezela u-enter ku
**my-firebase-project** **noma igama lephrojekthi olisebenzisilenoma igama lephrojekthi olifakile
5. Khetha
**Javascript** bese ucindezela u-enter
6. Ungasho
**Cha** ku-Ingabe ufuna ukusebenzisa i-ESLInt ukuze ubambe iziphazamisi ezingaba khona futhi usebenzise isitayela?

- I-ID yeqoqo
isampula
- I-ID yedokhumenti
isampula_doc
Sichaze okungenhla ngenkathi sifaka idatha yesampula
umsebenzi we-async getFirestoreconst firestore_con = wait admin.firestoreconst writeResult = firestore_con.collection('sampledoc('sample_docgetthen(doc =>{
uma (!doc.exists) {console.log('Ayikho idokhumenti enjalo }
okunye {buyisela i-doc.data
.catch(iphutha =>{console.log('Iphutha ekutholeni idokhumenti', i-errreturn writeResult
}
**Sisebenzisa Inothi: ** **async**ngoba kufanele silinde ukuthi umsebenzi wesithembiso uqedwe phakathi kweDathabase newebhusayithi yethu.
6. Dala umzila bese uthumela umphumela ekugcineni
app.getasync (isicelo, impendulo) var db_result = await getFirestoreresponse.render('indexdb_resultexports.app = functions.https.onRequest(app);
7. Dala
**index.hbs** ngaphakathi kwefolda ethi **views**. I-hbs iyifayela le-handelbar Qaphela: **
8. Bhala le khodi ye-HTML eyisisekelo ngaphakathi
**index.hbs** ukuze ubone umphumela olandiwe
