Node.js 26.0 er klassificeret som en version med langtidssupport, men denne status vil f\u00f8rst blive tildelt i oktober efter en stabiliseringsperiode. Supporten for Node.js 26.x vil blive opretholdt indtil maj 2029. Supporten for den tidligere LTS-version Node.js 24.x vil forts\u00e6tte indtil 30. april 2028, mens version 22.x vil v\u00e6re underst\u00f8ttet indtil 30. april 2027. Supporten for LTS-version 20.x oph\u00f8rte den 30. april 2026, og supporten for den midlertidige version Node.js 25.x vil stoppes den 1. juni 2026.      <\/p>\n<p>Key improvements:  <\/p>\n<ul>\n<li class=\"l\"> API Temporal er som standard aktiveret og tilbyder et alternativt s\u00e6t metoder til arbejdet med datoer og tid. API'et g\u00f8r det muligt at manipulere datoer b\u00e5de med og uden hensyntagen til tidszoner, konvertere tid, formatere output og udf\u00f8re aritmetiske operationer med tid. Tiden kan angives i en tidszone-uafh\u00e6ngig repr\u00e6sentation (Temporal.PlainDate, Temporal.PlainTime, Temporal.PlainDateTime), med tilknytning til tidszone (Temporal.ZonedDateTime) og i epoch-repr\u00e6sentation (Temporal.Instant - antallet af nanosekunder siden 1. januar 1970).\n<li class=\"l\"> V8-motoren er blevet opdateret til version 14.6, som bruges i Chromium 146. Blandt forbedringerne i forhold til den tidligere version af Node.js er muligheden for at sammenflette flere iteratorer til en enkelt med metoden Iterator.concat(), samt implementeringen af specifikationen \"upsert\" for at forenkle arbejdet med samlinger af n\u00f8gle\/v\u00e6rdi-par i JavaScript-objekterne Map og WeakMap.\n<li class=\"l\"> HTTP-klienten undici er blevet opdateret til version 8.x.\n<li class=\"l\"> Metoden http.Server.prototype.writeHeader() er blevet fjernet, og i stedet skal http.Server.prototype.writeHead() anvendes.            <\/ul>\n<p>Node.js-platformen kan bruges til b\u00e5de server-side drift af webapplikationer og til at skabe almindelige klient- og serverbaserede netv\u00e6rksprogrammer. Der er forberedt en stor samling af moduler til at udvide funktionaliteten af applikationer til Node.js, hvor man kan finde moduler med implementeringer  <a class=\"wpil_keyword_link\" href=\"https:\/\/prohoster.info\/da\/server\/\" title=\"servere\" data-wpil-keyword-link=\"linked\">servere<\/a> og HTTP, SMTP, XMPP, DNS, FTP, IMAP, POP3 klienter, moduler til integration med forskellige web-rammer, WebSocket- og Ajax-h\u00e5ndterere, forbindelser til DBMS (MySQL, PostgreSQL, SQLite, MongoDB), templating-motorer, CSS-motorer, implementeringer af kryptografi-algoritmer og autorisationssystemer (OAuth), XML-parsere.    <\/p>\n<p> For at h\u00e5ndtere et stort antal parallelle anmodninger anvender Node.js en asynkron kodeudviklingsmodel baseret p\u00e5 begivenhedsbehandling i ikke-blokerende tilstand og bestemmelse af callback-h\u00e5ndterere. Metoder som epoll, kqueue, \/dev\/poll og select underst\u00f8ttes til multiplexing af forbindelser. Biblioteket libuv, som er bygget over libev i Unix-systemer og over IOCP i Windows, bruges til multiplexing af forbindelser. Et tr\u00e5d-pool oprettes ved hj\u00e6lp af biblioteket libeio, mens integrationen af c-ares muligg\u00f8r ikke-blokerende DNS-anmodninger. Alle systemopkald, der medf\u00f8rer blokering, udf\u00f8res inden for tr\u00e5d-poolen og sender derefter deres resultater tilbage gennem en uspecificeret kanal (pipe), ligesom signalh\u00e5ndtererne.     <\/p>\n<p>Udf\u00f8relsen af JavaScript-kode sikres ved brug af V8-motoren, der er udviklet af Google. I sin essens minder Node.js om Perl AnyEvent, Ruby Event Machine, Python asyncio og begivenhedsimplementering i Tcl, men h\u00e6ndelses- (event loop) behandlingen i Node.js er skjult for udvikleren og minder om h\u00e6ndelsesbehandlingen i et webapplikation, der k\u00f8rer i en browser.<br \/>\n<br \/>Kilde: <a rel=\"nofollow\" href=\"https:\/\/www.opennet.ru\/opennews\/art.shtml?num=65374\">opennet.ru<\/a> <\/p>","protected":false,"gt_translate_keys":[{"key":"rendered","format":"html"}]},"excerpt":{"rendered":"<p>\u0421\u043e\u0441\u0442\u043e\u044f\u043b\u0441\u044f \u0440\u0435\u043b\u0438\u0437 Node.js 26.0.0, \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.
