Iz\u0161la je Node.js 21.0, platforma za izvajanje omre\u017enih aplikacij v jeziku JavaScript. Podpora za razli\u010dico Node.js 21.0 bo trajala 6 mesecev. V naslednjih dneh bo zaklju\u010dena stabilizacija razli\u010dice Node.js 20, ki bo pridobila status LTS in bo podprta do aprila 2026. Podpora prej\u0161nje LTS razli\u010dice Node.js 18.0 bo trajala do septembra 2025, prej\u0161nje LTS razli\u010dice 16.0 pa do aprila 2024. <\/p>\n
Glavne izbolj\u0161ave: <\/p>\n
Platforma Node.js se lahko uporablja tako za stre\u017eni\u0161ko spremljanje delovanja spletnih aplikacij kot tudi za ustvarjanje obi\u010dajnih odjemalskih in stre\u017eni\u0161kih omre\u017enih programov. Za raz\u0161iritev funkcionalnosti aplikacij za Node.js je pripravljena obse\u017ena zbirka modulov, v kateri lahko najdete module z implementacijo. stre\u017enikov<\/a> i HTTP, SMTP, XMPP, DNS, FTP, IMAP, POP3 klijenata, module za integraciju sa raznim web okvirima, WebSocket i Ajax obradi, konektore za baze podataka (MySQL, PostgreSQL, SQLite, MongoDB), predlo\u0161ke, CSS motore, implementacije kriptoalgoritama i sistema autorizacije (OAuth), XML parsera. <\/p>\n Za obradnjo velikega \u0161tevila vzporednih zahtevkov Node.js uporablja asinhroni model izvajanja kode, ki temelji na obdelavi dogodkov v neblokirnem na\u010dinu in dolo\u010danju callback obdelovalcev. Kot na\u010dine multiplexiranja povezav podpira metode, kot so epoll, kqueue, \/dev\/poll in select. Za multiplexiranje povezav se uporablja knji\u017enica libuv, ki je nadgradnja nad libev v sistemih Unix in nad IOCP v Windows. Za ustvarjanje sklada niti (thread pool) se uporablja knji\u017enica libeio, za izvedbo DNS zahtevkov v neblokirnem na\u010dinu pa je integriran c-ares. Vsi sistemski klici, ki povzro\u010dajo blokado, se izvajajo v okviru sklada niti in nato, tako kot obdelovalci signalov, rezultat svojega dela po\u0161ljejo nazaj prek anonimne cevi (pipe). Izvajanje JavaScript kode omogo\u010da vklju\u010den motor V8, ki ga je razvilo podjetje Google (dodatno Microsoft razvija razli\u010dico Node.js z motorjem Chakra-Core). <\/p>\n U su\u0161tini, Node.js je sli\u010dan Perl AnyEvent, Ruby Event Machine, Python Twisted okvirima i implementaciji doga\u0111aja u Tcl-u, ali je petlja obrade doga\u0111aja (event loop) u Node.js skrivena od programera i podsje\u0107a na obradu doga\u0111aja u web aplikaciji koja radi u pregledniku. Prilikom pisanja aplikacija za node.js potrebno je uzeti u obzir specifi\u010dnosti programiranja orijentiranog na doga\u0111aje, na primjer, umjesto izvr\u0161avanja 'var result = db.query('select..');' s \u010dekanjem na zavr\u0161etak rada i naknadnom obradom rezultata, Node.js koristi princip asinkronog izvr\u0161avanja, tj. kod se pretvara u 'db.query('select..', function (result) {obrada rezultata});', pri \u010demu \u0107e kontrola odmah pre\u0107i na daljnji kod, a rezultat zahtjeva \u0107e se obraditi po dolasku podataka. \u0421\u043e\u0441\u0442\u043e\u044f\u043b\u0441\u044f \u0440\u0435\u043b\u0438\u0437 Node.js 21.0, \u043f\u043b\u0430\u0442\u0444\u043e\u0440\u043c\u044b \u0434\u043b\u044f \u0432\u044b\u043f\u043e\u043b\u043d\u0435\u043d\u0438\u044f \u0441\u0435\u0442\u0435\u0432\u044b\u0445 \u043f\u0440\u0438\u043b\u043e\u0436\u0435\u043d\u0438\u0439 \u043d\u0430 \u044f\u0437\u044b\u043a\u0435 JavaScript. \u041f\u043e\u0434\u0434\u0435\u0440\u0436\u043a\u0430 \u0432\u0435\u0442\u043a\u0438 Node.js 21.0 \u0431\u0443\u0434\u0435\u0442 \u043e\u0441\u0443\u0449\u0435\u0441\u0442\u0432\u043b\u044f\u0442\u044c\u0441\u044f \u0432 \u0442\u0435\u0447\u0435\u043d\u0438\u0435 6 \u043c\u0435\u0441\u044f\u0446\u0435\u0432. \u0412 \u0431\u043b\u0438\u0436\u0430\u0439\u0448\u0438\u0435 \u0434\u043d\u0438 \u0431\u0443\u0434\u0435\u0442 \u0437\u0430\u0432\u0435\u0440\u0448\u0435\u043d\u0430 \u0441\u0442\u0430\u0431\u0438\u043b\u0438\u0437\u0430\u0446\u0438\u044f \u0432\u0435\u0442\u043a\u0438 Node.js 20, \u043a\u043e\u0442\u043e\u0440\u0430\u044f \u043f\u043e\u043b\u0443\u0447\u0438\u0442 \u0441\u0442\u0430\u0442\u0443\u0441 LTS \u0438 \u0431\u0443\u0434\u0435\u0442 \u043f\u043e\u0434\u0434\u0435\u0440\u0436\u0438\u0432\u0430\u0442\u044c\u0441\u044f \u0434\u043e \u0430\u043f\u0440\u0435\u043b\u044f 2026 \u0433\u043e\u0434\u0430. \u0421\u043e\u043f\u0440\u043e\u0432\u043e\u0436\u0434\u0435\u043d\u0438\u0435 \u043f\u0440\u043e\u0448\u043b\u043e\u0439 LTS-\u0432\u0435\u0442\u043a\u0438 Node.js 18.0 \u043f\u0440\u043e\u0434\u043b\u0438\u0442\u0441\u044f \u0434\u043e \u0441\u0435\u043d\u0442\u044f\u0431\u0440\u044f 2025 \u0433\u043e\u0434\u0430, \u0430 \u043f\u043e\u0437\u0430\u043f\u0440\u043e\u0448\u043b\u043e\u0439 LTS-\u0432\u0435\u0442\u043a\u0438 […]<\/p>\n","protected":false,"gt_translate_keys":[{"key":"rendered","format":"html"}]},"author":1,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[702],"tags":[],"class_list":["post-111020","post","type-post","status-publish","format-standard","hentry","category-news"],"aioseo_notices":[],"aioseo_head":"\n\t\t\n\t\n\t\n\t\n\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\n","aioseo_head_json":{"title":"\ud83e\udd47Na voljo je stre\u017eni\u0161ka JavaScript-platforma Node.js 21.0 | ProHoster","description":"Iz\u0161el je Node.js 21.0, platforma za izvajanje omre\u017enih aplikacij v JavaScriptu.
