Kawm ua siab phem Tshooj
Lub sij hawm tsuas txhais thaumtwg zoo yog thaum koj nyob nraum hais lus txog pawg phem.
PHEM yog hais rau MongoDB, Express.js, AngularJS thiab Node.js, tus coj JavaScript uas tsim lub software pawg. Ntawm no yog ib tug hais txog txhua yam ntawm cov coj:
MongoDB
Nws yog tshuaj Hmoob paub databases yuav tsum programmers thawj zoo tsim ib cov ntaub ntawv schema thiab mam li muab cov ntaub ntawv yuav tsum tau nyob rau tej ntxhuav. Thaum NoSQL databases tsis muaj schemas nruj, nws yuav hais tias koj tsis tas yuav tau kev schema nyob rau hauv tej databases unwise. Yog hais tias koj puas tau xav mus siv cov ntaub ntawv ntawd, muaj ib co ntaub ntawv los ntawm nws mus xyuas kom meej tias cov ntaub ntawv yuav tsum ua haujlwm raws li qhov ua tau npaum li schema tsi. NoSQL cov databases uas muaj cov muaj rab peev xwm ntawm storing cov qauv ntaub ntawv ntau ntau rau cov qub database, SQL xwb tsis (Nws yog zoo li cas cov NoSQL tau stands, NoSQL = SQL xwb tsis).
MongoDB yog ib qhov siv tshaj ncha lug NoSQL databases. MongoDB tshuav nqi nws cov chaw mus rau ob peb tug cov nta. Nws yuav muab humongous nqi nyiaj ntawm cov ntaub ntawv feem ntau muaj yuav luag tsis muaj qauv. Cia huab kuas yog tseem impressive vim nws tej yam koj siv nyiaj ntau. Tshaj tej ntawm nws muab rau koj raws li daim phiaj thiab ntau yooj. qhov tseeb, qhov yooj yog li tias koj yuav hloov hauv koj tej ntaub ntawv txhua hnub thiab tseem yuav raws sij hawm nrog koj Agile sprints. Nws tsis yog vim txoj kev loj hlob uas ceev ceev, tej no zoo nkauj thiab sai mas zoo li. Yog tus scalability qhia thaum pheej yig ib tus tshajplaws feature ntawm MongoDB.
Express.js
Nws yog ib tug yooj ywm thiab haum tsawg heev web daim ntawv thov kev moj khaum muab cov neeg robust nta rau tsim mobile thiab Web site daim ntaub ntawv. Express.js tso cai rau koj kom lawv muaj cov websites ntawm layering nyob rau hauv nws qhov kev siv built-in thiab cov lug koj puas yuav tsum tau tsim ib lub website. Nws tseem hnav thiab muaj built-in web app nta uas muab lub developers ib great yooj yooj yim thiab cov.
Thaum uas siv cov Node.js, Express.js pauv txoj kev uas koj yuav txhim ib lub website. Nws txawm muaj ib tug tshwj xeeb qhia API uas flawlessly xwb tsis override cov feature puv, robust Node.js platform. Yog li tseem ceeb heev rau cov software pawg li lwm tus coj yog Express.js.
AngularJS
Yog koj nyob nraum ua ib lub website dynamic, muaj tsis muaj tus yam ntxwv moj khaum zoo dua AngularJS. AngularJS pub rau cov designers siv cov HTML sau templates. Nws twb pub rau cov neeg mus cuag cov syntax ntawm HTML rau lub Cheebtsam hauv daim ntawv thov conveying theej effortlessly.
Ib yam ntawm cov kev pab cuam tseem ceeb ntawm kev siv AngularJS yog ib qho uas nws implements cov MVC thiab cov qauv. Cov ntaub ntawv ua qauv yog POJO thiab yog li no yooj yim rau kev ua hauj lwm nrog. Nrog AngularJS, chaws uas koj yuav tsum sau qhov nyiaj decreases thiab. Nws tsis cia li tau tus developers, tiam sis kuj lub testers vim nws yog chav tsev kuaj ready.
Node.js
Yuav tso nws cias, Node.js yog ib cheeb tsam JavaScript sij hawm mus dhia. Nws yuav ua tau rau lub V8 cav Chrome no los ua rau, li ntawd, koj yuav bet tias yeej ceev. Nws converts koj JavaScript chaws mus rau hauv lub tshuab code haiv neeg rau lub platform uas yog tau ua hauj lwm raws li qhov. Qhov no pub rau nws kom mus zoo raws cov speeds uas koj tsis xav kom nws ua tau kom mus zoo raws.
Thaum nws tawm los ntau-yuaj, Node.js stands raws li ib yam ntawm cov heev zoo tshaj. Tshaj tej ntawm, raws li JavaScript, yog nws yooj yim heev rau kev kawm thiab kev ua hauj lwm rau. Txhua yam koj xav tau no koj muab mus rau JavaScript, thiab koj txawj. Ua tus tsim tawm web, koj puas paub JavaScript vim nws yog ib hom lus uas koj yuav tau kawm.
Txawb thiab web kev tuam txhab uas muag cov tam sim no leveraging software pawg tsim dlaws amazingly spectacular. Thiab xwb vim muaj tus zoo tus phem pawg muaj rua suav dlawg. Muaj tej tus nws muaj zoo:
- Siv JavaScript
Yog ib yam ntawm cov tub ntxhais hom lus txhua yam web tsim tawm paub thiab yog adept rau, tus Disease fact txhua tshuab ntawm pawg phem siv JavaScript yog ib hom kev pab uas tab tom siv. Ntawm sab nram qab kawg yuav xaus rau pem hauv ntej, koj yuav npog nws siv tag nrho JavaScript. Yog tias tsis yog ib qho kev inviting, Kuv tsis paub tias yog dab tsi.
- Yooj yim rau twb
Large-scale tuam txhab uas muag tseem yuav ntiav ntau yam sib txawv tshwj xeeb rau kev ua haujlwm nyob rau hauv ib qhov ib zaug xwb vim rau qhov tej yaam num hu tias neb ob leeg, nram qab kawg thiab raws li pem hauv paus kawg. Nrog pawg phem, ho, lawv yuav tsis tau ua. Tus neeg ua hauj lwm nyob rau cov tshooj software yuav tsim tawm JavaScript tag nro-pawg, vim nws yog ib txhij software pawg. Tshaj tej ntawm, Yog koj saib rau nws los ntawm ib pab neeg tswj thiab tswv yim xav thiab pom, Nws tseem zoo nkauj yooj yim muaj ntau JavaScript developers hauj lwm tus tib neeg vim lawv muaj nyag haiv hab zoo sib xws.
- Siv JSON uas nws kim heev
Rau interchanging tej ntaub ntawv rau tag nrho cov khaubncaws sab nraud povtseg, Siab phem Tshooj siv JSON (Ceeb toom JavaScript nruas). Siv JSON txhais tau siv cim npe lesser dua XML, thiab ua koj cov cai tsheb thauj mus los-independent. Tshaj tej ntawm JSON yog ntau zoo ntawm cov txheej txheem kev txiav txim siab yuav txhawb hauv JavaScript raws li khoom. Vim siv cov JSON loj yog tias cov ntaub ntawv yuav tau txais tsis yog los ntawm koj tus kheej sau tab sis ntawm nyob txhua qhov chaw, li tshem tau lub npe servers. Tab tom siv nyob rau hauv tshooj phem pub rau koj ua nrog rau lwm APIs kuj yooj yim. Yuav ua li cas tus ntau yog tias nws tseem yuav tshem txoj kev siv qiv mus siv tau cov ntaub ntawv thaum muaj kev sis raug zoo mus ntawm tus neeg thiab cov neeg rau zaub mov.
- Tau qhov twg los qhib
Txhua yam ntawm tus yees hauv lub software Tshooj yog dawb thiab qhib qhov. Txhua tus uas los sis version ntawv kom ruaj cov software pawg ua yog ua los ntawm cov pawg phem developers. Nws lub zej zos uas developers txaus siab heev thiab tshaj txaus mus hais ntxiv rau peb tes num tseem.
