yew VS egui

I coded up a game of life implementation in rust and web assembly using https://yew.rs/ as an effort to sharpen my rust skills and it resulted as a fun toy. You can find the source here: https://gitlab.com/reedrichards/wvdom Enjoy!

I'm surprised nobody said they'd use [Yew](https://yew.rs/), especially given the premise of this being for a passion project.

1. Not related to npm, but related to the web.

2. True, but compilers are generally better than transpilers.

3. Have you seen https://yew.rs/ ?

You could use Yew to write web apps, which can be opened on Android phones.

What about Yew and Iced?

was hoping to keep it rust all the way through the stack with yew for the frontend in rust instead of using typescript. Gql could work if there are good rust gql client libraries.

they could use rust for the frontend too with frameworks like yew.

Thanks for the feedback!

It is definitely fixable. Take a look at https://github.com/emilk/egui/issues/996 for some examples of how others have styled egui, or try out https://app.rerun.io/

Styling is done with `ctx.set_style`, but creating a nice style isn't very easy at the moment (basically you'll have to tweak constants in code, and then recompile). I'm working on making it easier as we speak though!

Nothing is wrong with that, it’s rather a workaround, ultimately I am trying to have one language only including the UI too (been playing with egui),so I don’t have to use JavaScript.

I cannot recommend immediate mode GUI programming based on the limitations I've experienced working with egui.

egui does not support putting two widgets in the center of the screen: https://github.com/emilk/egui/issues/3211

It's really easy to get started with immediate mode, it's really easy to bust out some UI, but the second you start trying to involve dynamically resized context and responsive layouts -- abandon all hope. The fact it has to calculate everything in a single pass makes these things hard/impossible.

... that said, I'm still using it for https://ant.care/ (https://github.com/MeoMix/symbiants) because it's the best thing I've found. I'm crossing my fingers that Bevy's UI story (or Kayak https://github.com/StarArawn/kayak_ui) become significantly more fleshed out sooner rather than later. Bevy 0.13 should have lots more in this area though (https://github.com/bevyengine/bevy/discussions/9538)

That's fair. I don't have experience with other immediate mode libraries. It's good to hear that it's not an intrinsic limitation

https://github.com/emilk/egui?tab=readme-ov-file#layout Here the author discusses the issue directly. They note that there are solutions to the issue, but that they all come with (in their opinion) significant drawbacks.

For my use case, if I have to do a lot of manual work to achieve what I consider behavior that should be handled by the framework, then I don't find that compelling and am inclined to use a retained mode implementation.

AFAIK the Rust equivalent to C++'s Dear ImGui is egui.

The creator of Rerun (Emil Ernerfeldt) also created egui [1], an immediate GUI library for Rust. The library is similar to Dear ImGui but it is written in Rust and can be used for desktop and web apps (compiles to WASM and uses WebGL, demo [2]). Desktop apps can target OpenGL (does not display correct colors on macOS, does not work in VirtualBox on Windows) or WGPU (uses native APIs for each platform, works without any problems, but the binary is a big larger).

> [...] you can build UIs that are snappy and keyboard driven.

That's not an advantage that is exclusive to TUIs; after all, you're running your TUI inside a graphical application that emulates a terminal. (Unless you're rocking an actual VT102, in which case I bow down to you.)

In fact there's an entire class of applications that are extremely snappy and keyboard driven, by their very nature: games.

Some people have taken to writing GUI apps like you'd write a game, and the effects range from OK to fantastic. Check out Lagrange (https://gmi.skyjake.fi/lagrange/), AppManager (https://tildegit.org/solene/AppManager), Dear ImGUI (https://github.com/ocornut/imgui), egui (https://github.com/emilk/egui), and many others.

Honestly, frontend development especially with all these crowded frameworks and libraries always confused me so pardon my ignorance, which is why in a project I’m working on right now I’m trying not to use js, instead I’m using egui [1]

Zola is a static site generator and it’s crazy fast, using one binary only [2], also there’s Blades [3], same concept but supposedly faster, never tried it though.

egui for a GUI library that makes me cry when I want to layout something simple but provides very powerful manual control over things
