hello

dost som stravil posledne mesiace researchovanim vela roznych frameworkov a cmsiek, vid nizsie kde som sa na to pytal, tak dost do hlbky som pozrel viacere, tak tu je moj zaver (je to oficial z interneho #research slack kanalu, ale myslim ze je to relevantne dat aj sem)

---

after researching all the backend CMS-es for PHP thanks to sajid and sharik, and now after researching all the NodeJS frameworks/cmses with sajid, i came to conclusion that there is just nothing like laravel, only adonis, and that there is nothing like october, like nothing - there are bits of features that i love in some frameworks which i would like to have in october, i think it would be wiser to simply list out all the features that we like and get inspired and build those for october, october is not perfect, but it feels to me that with our limited resources and skills and time, the fastest path to perfect CMF will be to just copy the competing frameworks.. i must say i feel like i’m surrendering to the old PHP world, but their constant improvement in language (like new features in PHP 7.4) and sophisticated FW/CMS just pushes me to take what we have and if we want something better, i dont think we’ll find it anywhere, yes the october has its limits, but i think all except for php language can be solved… i’ve started writing down the features i like in competition and i’ll try to also compile opinions in our team (u can share in thread, and i’ll be asking personally too) to see what is really making it hard for us when developing.. i wish to have CMF and backend stack that will be equal to any buzzword technology out there..

pre zaujimavost, na node sa mi najviac pacia:
- adonis
- feathers
- strapi
(nest vyzeral cool ale sklamal ma, je to len microframework ako express, neni to robustne ako laravel)

a pre info ze co je to ten october, tu je nejaka moja prezentacia:
https://docs.google.com/presentation/d/1a2QGwW9TtlJ8lMCetGddhLzRCvHbPDlMm2Gs_mjYn6I/edit#slide=id.p

tu je moje rok stare video kde som za 15 minut ukazal v praxi ze ako to rozbehat a pouzivat a poukazoval preco sa mi to paci: https://www.youtube.com/watch?v=orPr9cUGmOo

o rok neskor uz je to trochu dalej, porobili sme si kopec pluginov, spravili niekolko meetupov, dokonca sa tento content framework ucia aj v OpenLabe (vzdelavanie vramci strednych skol vramci vyucovania moderneho programovania s ludmi z praxe http://openlab.sk/ )

o tyzden v pondelok 12.8. bude Show me your code beer, na temu NodeJS Frameworky (Express, Adonis, Nest, etc.)

ak rozmyslate ze by ste nejaky z nich vyskusali..
alebo ak mate skusenosti s nejakym nodejs frameworkom..
..tak pridte pokecat

hello

pred par mesiacmi som si robil research CMS-iek postavenych na angulare
chcem tym nahradit drupal, ze by cela firma presla na to a zabudlo by sa na php/mysql

tj malo by to umoznovat:
- narychlo vyklikat strukturu webu
- customizovat obsah angularom
- musi to mat jednoducheho CMS admina
- a api na custom objekty

dopadlo to asi takto:

budem robit znova research, ale chcel by som poradit, ci sa medzi casom neobjavilo nieco s cim sa lahko robi
angular2 by bol plus, lebo je popici

000001010006354001487459066879960824691608649981

inak nakoniec som nic dobre nenasiel
presiel som na phpckovy, laravel-based OctoberCMS co je v podstate taky content management framework, nie je to v podstate ani cms

teraz pozeram po adonis js, co je klon laravelu do nodejs
avsak chcem tam najst nejaky obdobny content framework
a chcem to pouzivat headless (len backend a api a admin nech je nezavisly) a serverless (aby to bezalo na aws lambda, aws fargate, etc, nech nemusim uz nikdy setupovat server a nech platim len za vyuzity vykon, nie ze beziaci server)

zaujimavy clanok, a paci sa mi real-world experience :)

Ja by som node do produkcie vybral iba na velmi specificke veci... Pouzivate v produkcii node?

00000101000635400148745906687996081422180814232308142335

ja momentalne riesim node na hobby projekt(primarne socket.io), ale stale sa uplne neviem rozhodnut ci s nim chcem riesit aj backend s relacnou databazou.

0000010100063540014874590668799608142218081423230814233508143955

aky je v tom rozdiel? nerobis v oboch jazykoch tie iste veci?

000001010006354001487459066879960814221808142323081423350814395508144015

v oboch akych jazykoch?

00000101000635400148745906687996081422180814232308142335081439550814401508144019

php a nodejs, neni sa tam o com rozhodovat, bud sa chces posuvat alebo neriesit a zostat pri tom na co si zvyknuty

0000010100063540014874590668799608142218081423230814233508143955081440150814401908144030

ja som v php vzivote nekodil.. az na zopar vynimiek ako je kyberia..

0000010100063540014874590668799607839996

pm2 pouzivate ?

000001010006354001487459066879960783999607840029

vcera som nato pozeral v ramci sane stacku https://github.com/artificialio/sane tiez ma to zaujima vcelku, ty si to skusal?

00000101000635400148745906687996078399960784002907840036

no aj hej, existuje k tomu aj pm2-web

ja som to nasiel ked som riesil to ako vyuzit viacjadrovy server "easy" way, co aj celkom fici. len je to este take trochu meh (hej pisu ze cluster mode je este beta)

0000010100063540014874590668799607839996078400290784003607840043

kk, tak ked budem tak daleko, ze budem riesit load tak sa mno ozvem .)

Inak neviem aky je tvoj use case, ale mozno sa dobre utilizuje 4Core cez rozumnu virtualizaciu, tj. lxc/docker, kde si pustis n kontajnerov, kazdy dostane svoje prostredky (dajme tomu 1Core per container) a potom by sa to mno dalo este lepsie utilizovat. Ale hovorim, netusim aky je use case, keby ale pokrocis tak sem postni nejaky progres, nech neslampeme rovnaku cestu 2x. Dik!

inak podobnu a sirsiu funkcionalitu poskytuje aj http://strongloop.com/

000001010006354001487459066879960783999607840029078400360784004307840051

no s nodou sa momentalne viacmenej len hrajkam, zatial to na nic vacsie nepouzivam. mam v tom "az" jeden projekt, ktory funguje principialne ako proxac/man in the middle ktory musi nieco urobit ked pride request od klienta a nasladne ked pride response od proxynovaneho servera zas spravit nejaku dalsiu akciu. a to hlavne kvoli tomu ze ten proxynovany server je proste nieco s cim sa nehybe inak by som tu logiku hodil nanho. = prepajpovavam data z klienta na server a spiatky, a popritom pri nejakych eventoch poslem nejaky request na databazu alebo jemne pozmenim http headre.

akutalne to pm2 vyuzivam hlavne ako monitorovaciu zalezitost a ked to budeme releasovat do ziveho prostredia, zrejme to pouzijem ako service konfiguraciu - nech sa to pekne samo nastartuje pri reboote a podobne.
clekom fit je rychly reload aplikacie ked nebodaj padne, alebo aj watchovanie subprov -> restart aplikacie ked nahras novy zdrojak a tak.. co sa mi clekom pozdava.

00000101000635400148745906687996078399960784002907840036078400430784005107840144

ako pises v node sa daju robit sialene veci :)

inak co sa tyka watchovania tak som z nodoveho file-watchera presiel na watchman-a a na unixe je to poznat (hlavne pri rebuildoch hutnejsich projektov)
na triggrovany reload pouzivam livereload a funguje bez issues.

na ten pm2 som pozreal pretoze ma zaujimalo ako manazovat niekolko nod za nginx.

Elasticsearch is a great way to store lots of documents that need to be quickly searched and retrieved. In addition to a broad query API, Elasticsearch also provides scrolling functionality that lets you query the server and incrementally download the results. This can be really useful for processing any large result set, e.g. for reindexing.

Generator based flow-control goodness for nodejs and the browser, using thunks or promises, letting you write non-blocking code in a nice-ish way.

a note to performance:
On my machine 30,000 sequential stat()s takes an avg of 570ms, while the same number of sequential stat()s with co() takes 610ms, aka the overhead introduced by generators is extremely negligable.
