This video will walk building a simple DOM rendering library in Rust, starting with the basics of DOM manipulation and interaction with browser APIs and incrementally building up from there.

Based priest Greg descends from the mountains to teach us more rust while his birds watch over him.

I am reading leptos book in progress and love the way you don't miss to explain basic concepts. It can be even recommended to someone who has just started with rust.

thats really awesome that a small change doesnt require a complete re-rendering

this was an awesome video! the audio quality was fantastic. the birds sounded like I was relaxing in the jungle learning about rust and wasm

After struggling with learning leptos for some time, I finally kind of get it after watching this video.

This is an excellent introduction to building a web framework full stop! Thank you for the insight; definitely checking out that signals video.

I really appreciate these from scratch type videos. They really teach you so much more and share so much knowledge. It really speeds up other developers journeys into these deeper areas. I am sure the first time learning all this was not as easy as this looks. Many thanks!

Would love a breakdown like this for some of the server side rendering / logic. I am not sure how complex this would be, but it really helps me understand the frameworks.

Appreciate the way you explain the basics as you go. With WASM changing so quickly its nice to not require too much WASM background knowledge

That was a good first step, I hope you will have time to build and show us some more advanced stuff

This was great Greg! Can we get some detailed "how-to" tutorials for Leptos please?

Around 29:00 when the nothing but the value changes and no other DOM node. … I said wow audibly. I’m a Leptos evangelical now - I get that solid etc will do the same but having it in Rust just makes it so much better

Indeed, very interesting. I like the builder pattern more than JSX and so I am also currently playing with Rust and Wasm-based Web UI (but with futures-signals from dominator 😉) and I'd like to know more about this Scope stuff. Do you have any resources I could read/listen/watch that also helped you building that into leptos? Thanks.

There is a short section about the runtime context in one of his previous videos. It's in "Learning Leptos: Build a fine-grained reactive system in 100 lines of code" and starts around 04:31, showing more how signals and effects work together.

@gbjxc Жыл бұрын

Cool! Leptos does also have a builder pattern/you can use it with zero macros and on stable (see example here github.com/leptos-rs/leptos/blob/main/examples/counter_without_macros/src/lib.rs) Re scopes: it’s a little hard to explain in a YT comment and I don’t know that I have anything published about it. This post from Sycamore lays out a very similar problem space sycamore-rs.netlify.app/news/new-reactive-primitives Rather than using references with lifetimes tied to a Scope via bumpalo (as in Sycamore), Leptos gives Copy + ‘static signals by storing reactive values in a slotmap and passing the indices around. Scope is kind of your handle back into that reactive system. Basically a way to model a deep reactive graph without needing to .clone() signals and move them into event listeners everywhere, etc. futures_signals is great although it’s a somewhat different model of reactivity (not auto-tracking dependencies, etc.)

Yeah toward the end of the stream I did with Ryan Carniato I show how ActionForm works even with WASM turned off. Using normal links and forms (via and or ) is how we do this in Leptos. Link to stream with Ryan: kzbin.infozgY7ql1xwW4 I’m on for the first two hours or so.

@Bechmark Жыл бұрын

I'm left with one question: what's the proper way of doing the "leaking" without using the `.forget()`?

@gbjxc Жыл бұрын

To do it without leaking we could do something like us on_cleanup() in Leptos to keep it alive until the reactive scope it’s created in is disposed. Remember “leaking” in this sense = not reclaiming memory until you navigate away from the page so a click listener on the root of an app like this is always leaked anyway (because as long as the button is there it needs to exist)
