sycamore-mac VS webview

Not inherently, but practically yes – currently. There are attempts to use it for desktop ui https://github.com/Submersible/sycamore-mac but in general nothing prevents you from using it as you like and implement a backend you need.

Sycamore. And before people start complaining that it's just a webview or a browser in disguise, I would like to add that Sycamore was built from the start to allow multiple render backends. Right now, there are only backends for DOM and SSR (Server Side Rendering) but it should be pretty easy to extend it to native UI frameworks. In fact, there is a POC here of Sycamore running on macOS: https://github.com/Submersible/sycamore-mac although it is right now far from usable.

I used this a bit, it was really great. Writing a Rust backend & exposing it to TypeScript was really slick!

There was one issue I ran into that made me think about jumping to Electron mid project, but I can't remember what it was now, but I think it was something like making my app bleed the entire MacOS window while still being moveable.

The other downside is you're going to be tempted to go down the rabbit hole and do everything in Rust. [1]

You can create the webview using each platforms native GUI toolkit and setup JS communication yourself OR you can use a lightweight library that does it for [1] (search its README for language "bindings").

Each platform has it's own webview control available as a shared library installed with the OS.

MacOS has WKWebKit based on WebKit.

Windows has WebView2 based on Edge/Chromium.

Linux has webkit2gtk based on WebKit.

Tools like Tauri use a simple cross-platform single-header abstraction called webview.h[1].

Electron no longer allows Node.js to be called from renderer processes, all communication with Node.js is done via IPC.

In this case, why do we still need Electron? Why does it have to be tied to V8/Node.js?

The fact that Chromium Embedded Framework exists and is third-party makes me think that Chromium wasn't designed for being embedded, and Electron is filling that gap.

This is elucidated here further here https://trac.webkit.org/wiki/WebKit2:

> it's difficult to reuse their work...if another WebKit-based application or another port wanted to do multiprocess based on Chromium WebKit, it would be necessary to reinvent or cut & paste a great deal of code.

It makes me think that perhaps WebKit was the better choice for embedding. The fact that Node used V8 made Chromium the choice, and that Node being called from the renderer was the original way of working. Maybe because WebKit didn't have a build for Windows was an issue too...

But now that we have Bun, perhaps it's time that WebKit becomes that browser target of choice for desktop apps on macOS.

Unless WebView2 for macOS arrives, which would have a more sane cross-platform story. WebView2 has a very large feature-set though which make take a while to implement for macOS.

Nui could base on this in theory. Nui uses https://github.com/webview/webview under the hood, which provides browser windows for linux, windows or mac. Nui adds some cmake to make the "in-browser" and "main-process" part appear seemless, as well adding a DSEL for the "in-browser" view part.

WebView 7k

You mean something like this?

Golang can compile to windows statically, and on Windows those bindings are using the MSWebView2 API (aka Microsoft Edge webview).

I know that you can also compile the webview.cc into a dll specifically, and link against that. But I'd never done with Visual C++ because I am cross-compiling from Linux to Windows.

The README of the webview/webview project refers to the WebView2 SDK on NuGet, however [1]

The author shrugs off web tech (maybe because of electron bloat?) but you can avoid the bloat by using each platforms native web browser control. There are even cross-platform libraries that make creating the native control and cross-communication simple. These applications would be architecturally similar to Win32 apps using and communicating with a XAML Island, but the advantage of web tech is it's an open standard and WPF/WinUI is not.

For example, you could use a native webview (Edge WebView2 for Windows and WebKit for MacOS/Linux), which uses much less RAM than Electron.
