[@samiullahsheikh5015]

Can you help me to understand how someone can use htmx with react like prime mentioned some people do so?? I thought about both react and htmx in htmx vs react mind set

[@gradycdenton]

​@@samiullahsheikh5015 1st ask yourself if you REALLY need React. Use HTMX to create a mount point and React DOM to mount your app to that element. It's what you normally do with your main element on the index page in a SPA architecture, but you are doing it Island style.

[@mrkinetic]

I don't think it'd be much different from using only react on a static html page. Only difference is that htmx can alter the DOM. So you just have to make sure htmx is not updating anything inside the react tree, and that react components aren't mounted on dom elements that htmx is responsible for updating. I imagine you wouldn't want your react components adding any htmx attributes to the dom elements it creates either.@@samiullahsheikh5015

And the algorithms course

[@decoyslois]

This is a really interesting format. Instead of KZbinr - person talking to camera, or lecture - person talking to audience, this is more like a tutorial in the classical Oxford/Cambridge UK university style where it’s talking to a small group of people about topics they know about so you get some informed responses. It would be cool to adopt this idea a bit further - have some people bring in their work and you react/critique it in real time.

[@Kane0123]

The way he is doing code live, going through all those little issues, forgetting this or that is super normal. However - he is so gosh dang quick on the keys that it doesn’t feel tedious or disengaging.

[@kevinlyman1]

I would love to see that. There's this channel I watch from time to time where people submit their projects to the guy and he goes through it and critiques it. I think he used to work at EA, maybe on whatever engine FIFA or whatever it's called now runs on. But now he builds his own engine and has his youtube channel.

[@chunky5monkey]

Good luck, I believe the beauty of how HTMX is meant to be used is you can gradually migrate to fully HTMX if that makes sense or utilize both. It really goes to what makes sense for the product.

[@chunky5monkey]

@@okie9025 why is sending client-agnostic data better than just sending HTML? That's a bold claim with absolutely nothing to back it other than an attempt at an insult. By the way, almost everyone sends HTML for the initial request (i.e. index.html) in order for your web app to load all of your javascript.

[@whimahwhe]

[@MrTallAndy]

Love the simplicity, the whole frontend, backend split JSON transformation via API back into HTML always irked and felt like an over complexity. We seemed to invent a million different tools and frameworks to make it hard for ourselves. Refreshing to see an elegant solution 👏

[@ihateidiots9484]

It is not elegant, it's awful actually

[@okie9025]

This is the first time in 8 years of developing software that I've seen someone claim that separating the backend from the frontend and using JSON to communicate is "an over complexity". HTMX is not elegant at all, and going back to monolithic backends which use templating engines will make the web devolve back into web 1.0 when having clickable buttons on a website was incredible.

[@MrTallAndy]

Plenty of companies have monothlic node/go etc backends servicing frontend Javascript frameworks. HTMX can work with any backend, monolithic, service orientated, micro services, i'm not saying lets throw everything in the bin, but I think HTMX will certainly grow in popularity and will certainly be the right tool for the job in certain situations. Have you tried building something with it?

[@BekhterevFlight]

I just want to thank you for making these colaborations. People like Prime actually give insane amounts of value and TEACH you how to use HTMX and w/e he is teaching about. There are so many "tutors" who don't have 30% of the knowledge or passion that Prime does, that try to teach these subjects.

[@zacharythomasrobertson8471]

I think it's hilarious that we've finally come full circle back to xhr and vanilla js😂

[@Pictor13]

Less is more, after all. Those were at least honouring the existing web standards and concepts like HAETOAS, while javascript world started duplicating state multiple times (in the DOM, or additional variables, or into full fledged state management libraries). Everything became unhealthy complicated in frontend world as a consequence (provoking even more problems to solve). Imho, only because Hypermedia was simply not studied enough. Htmx provides a straightforward declarative way to start from where we got lost and do what we did over and over with AJAX (so, tired of doing that, we invented reactivity, betraying the HAETOAS nature of the web). Although I totally understand why people were excited about reactivity, in ~2013, I believed we are slowly coming back to the right/sane path. I also hope this path will lead to a reduced memory footprint of modern webapps, and better handling of offline state.

HTMX is fantastic! Goes great with Clojure too

[@jas0x139]

I'm loving HTMX. I was toying around with it using an Express server. Kept adding things and damn, I just re-created my personal website but much much simpler. I didn't even need a template engine because a for loop and some pushing database content + a little html to an array then ending with res.send(content.join(' ')); does the same thing. The simplicity has me over excited. I even created a markdown editor to preview my blogs/notes/articles using HTMX from the same Express server.

How does that work? The line "c.Render(200, "display", data)" Or is there a separate display.html that is being used as the template for this line?

[@blahblahblah3149]

Me too! Luckily HTMX doesn't care what you run on the server.

[@okie9025]

​@@blahblahblah3149Not true. HTMX only supports HTML responses. Any other frontend framework can handle literally any format you throw at it. There is no point in creating a whole different service on your server for sending partial HTML widgets (which is a huge hack if I've ever seen one) if you can just configure all of your apps to use JSON.

[@daedalus5070]

Prime made a GameOfLife game, all the real time interactions you can do with JS or use Alpine and then save the players "state" at the end of the turn using HTMX quite simply. I believe he has as video on his channel about it somewhere. HTMX also has WS/Server events as well that might be useful to look into for a multiplayer game.

[@keithjohnson6510]

Inside your HTML create a named element, and then from React mount this element. There is also nothing stopping you having 100's of instances of a React Root elements that sit inside elements created from the HTMLX output. This is no different from mixing any web framework with React, eg. you could mix jQuery with React. Most people use React as a full page SPA handling routing logic etc, but you can use React to just render a single component if you so wished.

[@samiullahsheikh5015]

@@keithjohnson6510 thank you. I never thought about react in this way. But yes just keep working with SPA somehow made me believe that there is only one way to do frontend. But I'm glad due to prime and @keithjohnson6510 i have a new perspective

[@salookie8000]

seem useful for refreshing server state back to client browser state without refreshing page....An advanced replacement for legacy AJAX

[@keithjohnson6510]

To me HTMLX is really another take on something like {{ mustache }} mixed with jQuery. I can understand the appeal of it, especially for back end devs. One thing I think JSX front-end frameworks really have an advantage here is composition, watching this video there appears to be no easy way to do this with htmlx. I also think this push to place more work on the server end always feels like a step backwards, especially in this day and age, front-end dev has never been easier.

[@camstuart]

HTMX looks really cool, and I must say, working in Go has always been a pleasure. But here is what worries me about “going against the norm” (even though the web dev current norm has spiralled into total insanity). How do I do all the things? For example, authentication, realtime ui updates, large application layout, testing, csrf….. I’d love to build up from scratch with a tech combo like this, but there is just too much risk that I’m going to hit some kind of show stopper!

[@ThisNoName]

This is just the old server side rendering stuff, no new challenges. Back in the days, it looks something like label ic-on=mouse-hover ic-post=/foo ic-target=bar ic-effect=fancy ... You can throw jquery selector and css syntax in those attributes to get creative. It's simple and effective. In fact, so simple you are going to have a hard time convincing anyone to adopt it over hello world with 600M of NPM packages

[@JohnMcclaned]

Yeah we are going to need to spend the next decade building some sort of reactive layer on top of htmx. can't wait!

[@florentd.5817]

[@adamdrake39]

[@inujascha8311]

Is this just on steriods? I try to understand where the innovation is. Because that is litterally what I do all the time. Throwing in some data attributes and emit my data as custom events and than catch them with the attribute value as a event name. Saving changes directly in the html if needed. I build a fetch function to get my templates for constructing controls at runtime and paste in some defaults with ejs or send a locals object to preset the new control. You call it "htmx-target" I call it "data-action".

[@TehKarmalizer]

That’s a good question. I’m unfamiliar with web development in practice, but that does sound quite similar.

[@NotAFanMan88]

HTMX isn't a templater like EJS. It'd be paired with one, though.

[@ThisNoName]

It's not a new thing. This was once a simple framework that let you keep server side rendering and do partial page refresh. It basically takes care of those event/fetching/catching/saving for you, kind of declarative-ajax-ish-partial-html-fragment-exchanger. It was called intercooler.js back in the days, something like span ic-post=/foo ic-target=bar ic-effect=fancy Lots of the jquery selector syntax works within those attributes, so you can get really creative if you want to.

[@qwerasdfhjkio]

​@@B20C0the average svelte app is 1.6Kb tho But I understand that svelte(kit) is more of a frontend first framework, whereas go+htmx is more of a backend first mentality

[@chunky5monkey]

There's quite a few reasons, but I don't know where to start. What are your concerns? This literally is the easiest server side rendering (SSR).

[@24wherath36]

Well think about it like this: You're already sending JSON through your API endpoint to your application and then using the information in that JSON to render HTML on the client. Now, you don't necessarily have to use JSON, you could use another messaging format like XML for example, or maybe a derivative of XML; HTML. Then you don't have to convert between your messaging format and the client representation format HTML. So instead of doing: SQL->(backend lang)->JSON->(JS)->HTML You can do: SQL->(backend lang)->HTML What is the difference in using HTML or JSON? JSON may be more compact, but it leaves out a bunch of information on how to represent that data on the client that you still have to send to the client anyway in the form of whatever JS framework and client-side code you're using.

@@24wherath36 You are correct that it cuts out a step but there's also the BIG issue of no longer having to manage multiple states.
