Looks like it uses system webviews instead of bundling a copy of Chromium? This to me seems like the real headlining feature, but strangely I had to dig pretty deep to find it: https://tauri.studio/en/docs/getting-started/technical-detai...

I kind of wonder why it took this long for someone to try this approach. It just makes a whole lot more sense on the surface.

Interesting thing I just thought about: since users don't get to choose their system webview, I wonder if this has the potential to broaden browser diversity a little bit?

A major benefit of Electron is that you can develop against a single browser and runtime version and don't have to deal with all the small but time consuming compatibility quirks.

On Windows the default webview engine is still not the new Chromium but old Edge (WebView2 has to be installed separately), Safari has a fair amount of issues and gtk-webkit can be very quirky as well.

This is not so significant if your app has a web version and you have to deal with it anyway , but thereare a fair amount of Electron only apps. Or even with a web version, the desktop app often has special features not present on the web.

But webviews are as much a moving target as browsers and often behave differently from the regular browser version in a myriad of ways, so you need an even bigger testing matrix.

Webviews are also hard to properly secure and don't provide the extensive APIs of Electron, which you often have to bake yourself in a wrapper written in, eg, Rust or C++.

I say all this as someone who hates how resource hungry Electron apps are and groans each time about yet another one on my machine, but I understand why it is so popular.

I say this as a front-end web app dev who would most likely be affected by this kind of shift: it might be slightly less convenient, but I wholeheartedly think it's worth doing, on several levels.

People built web apps 15 years ago in the dumpster-fire that was web standards at the time (and frankly, web tooling too). Browsers, even the good ones, didn't update themselves automatically. Most of the world was still on IE which was actively hostile to web standards for the sake of lock-in (and users weren't even on the same version of IE!). There was nothing like Babel to smooth over the rough edges, there were no polyfills. And even the standards that existed, when you got the opportunity to use them, mostly sucked.

I think, given all that, we can deal with supporting recent-ish Chromium and the latest Safari, if it means bolstering web diversity and saving an order of magnitude in RAM and storage.

Also: a lot of our "Electron" apps are essentially Electron frontends to the existing web frontend.

For example, Slack-the-Electron-app and Slack-the-web-app are fundamentally identical, aside from likely some platform integration features and so on. That means that, likely, a lot of these Electron apps would already work in, for example, a Safari or Edge webview, since the web version has to anyway. I sincerely doubt that they're taking the time to strip out that compatibility, since the only reason to do so would be efficiency and if you're using Electron that's not a priority.

IOW, for many applications, there's a near-100% chance that everything would function with little to no extra work, and for most of the rest it would likely take very little.

That's fine for someone who already keeps current with front-end stuff, but someone who is a desktop app developer is more likely to just go native than try to make a desktop app that tracks 3+ browser engines of wildly varying versions (luckily 7 is out of support now, but it still might be desired to support for some desktop apps in which case now you have IE to deal with). Electron gives the promise of total code re-use across platforms which is what makes web technologies more suitable for desktop apps.

I run three browsers on my desktop, because the number of things that don't work properly in anything except recent Chrome is enough that I keep encountering issues, I don't want to use Chrome for my regular browsing, and both Safari and Firefox have issues on some sites.

On my tablet, a number of current websites don't run even on Chrome, because the tablet isn't particularly new, so it doesn't have current Chrome. It's still great hardware in perfect condition though, everything that does run on it is perfectly smooth and so on, and I still use it. Youtube in particular is fine. Literally the only reason to buy a new one would be to satisfy the software treadmill.

My old phone didn't run Chrome (or Safari). It had Firefox. The only reason I switched to a newer phone, using Android, was because of sites that gradually didn't run well on Firefox any more. That was annoying, having to ditch a perfectly great phone and replace it with something better for the web but worse for other things.

I have a Macbook Pro at home. I'm pretty happy with it, it's still a fine machine, I use it for work every day. It runs the latest Safari that's safe to run on it, but that's not the latest Safari, because it would have problems running the most recent OS.

This brave new world of "I'm sure we'll be fine supporting recentish Chrome and latest Safari" is a world of exclusion. I don't like the memory usage of Electron, but I prefer it to applications that are a bit broken!

Also, to be honest, I've been looking at memory usage. Electron uses much less than any of the three big browsers. You may know that Chrome famously starts a new process for each tab, and Safari does too. Firefox isn't far behind. As a result, the memory saved by running a new page in an already running browser compared with Electron isn't as much as it was long ago, back in the days when tabs shared memory. This is visible with Safari, as the website name shows up in the system utility for viewing process memory.

I know, that feels wrong somehow, but it's true.

Finally, when using a system WebView, will that save memory if it's opening a separate instance of the system's browser? It must be separate in some ways, if opening an application that uses a WebView doesn't open all your saved tabs from last time the browser was open. (And it's a horrible experience if opening an application does open all the other tabs.)

Even worse, an OS update after you ship your app can spontaneously break it on end user's machines without you knowing or being able to do anything about it.

At least with the web, when new browser versions come out, you can fix your site since users essentially "install" it every time they refresh the page. But an installed app that runs on top of a spontaneously updated framework is the worst of both worlds.

But why would the system webview be less resource hungry? If it runs in an own process instance, the only memory you safe is (maybe) the executable code (i.e. maybe 100MB max).

Or you would need some common runtime which is shared across the OS, and somehow use IPC to it. Then you can potentially save some more memory. But I don't think this exists. And I'm also not sure how much you really would save.

The advantage of using the system webview is that you can update this component, in case there are any vulnerabilities or so.

Good, then developers might start to develop against standards instead of handpicked browsers. Or if they use a future (unstable) standard that is their own headache (as opposed to user’s; which are subsequently in practice forced to use chromium derived browser).

An app developed against a single browser (as opposed to the web standard) should be considered what it is, an ugly hack, and developers that do it should only do it for their own private apps never to be published until it is standard compliant.

12 hours ago by hobofan

This is about desktop and not web development though. I agree that pages available on the web should be standard compliant and work with all browsers.

On the desktop you are developing against a runtime that the developer of the app gets to choose, so why not choose one that has less potential for quirks?

People have been trying the WebView approach for years. (Projects include: Quark, Electrino, DeskGap, Revery, and Neutralino.)

Historically, it worked terribly on Windows.

On Windows, if you used the OS WebView, your Windows 7 users would be forced to use IE11 to run your app, even if they had a newer/better browser installed locally. On Windows 10, you'd get whatever random version of Edge was installed, or the new Chromium-based Edge.

In 2021, we're in a new era for Windows WebViews, thanks to Microsoft shipping WebView2 at the end of 2020, which ensures that the OS-provided WebView will be a modern version of Chromium. https://docs.microsoft.com/en-us/microsoft-edge/webview2/ Tauri supports WebView2 and I bet it will work a lot better than historical approaches.

Support is still pretty dicey on other platforms, though. macOS doesn't have anything like WebView2, so if you want to support a five-year-old version of macOS (which isn't that old in desktop terms), you'll be forced to support and test your app on a five-year-old version of Safari. (The user might have upgraded to a two-year-old version of Safari, but they might not, if they prefer Firefox or Chrome, and that's now your problem.)

The easiest and best way to improve the user's experience on old OS versions is to provide your own copy of Chromium, like Electron does.

At that point, if you've shipped an Electron app for macOS and Linux, maybe you just wanna ship an Electron app for Windows and call it a day?

Having said that, if you can keep your OS-version support matrix tight, Tauri might work OK for you.

Fortunately MacOS users upgrade very quickly. High Serria which is slowly waning at 7% came out in 2017. Compared to windows where twice as many (16%) at still using Windows 7 and won't be able to download the Webview2 update which Microsoft kindly provides.



Really depends on your market I guess and how much legacy webview browser support you need.

Or really how much you'd need to add polyfills like `@babel/preset-env` to keep the JS equal.

We use the WebView approach for Kreya[1], though not with Tauri. We had some occassional issues with Chromium/Safari differences, but otherwise it works fine.

We use WebView2 on Windows, Safari on macOS and WebKit2GTK on Linux. Not shipping a whole Chromium installation on each install and update reduces the installer and on-disk size a lot!

DeskGap uses the native OS Webviews. https://github.com/patr0nus/DeskGap/

Webviews don't work because they solve very different problems.

System webviews will always have different features, break things, and are entirely uncontrollable by the software distributor. This means your software will not be resilient to the future.

You cannot access the JS engine the same as you can V8 in most webviews. This means you can't interop with C libraries without some performance destroying hack like copying everything into the JS space through sockets.

This also means something as simple as reading a file has to, again, cross the sandbox in an inefficient way. You'd have the browser, it's javascript engine, and your own runtime in node or python or however too.

Electron develops patches that make chromium more performant and feature ready for desktop.

Electron conjoins the chromium and node v8 event loop to take advantage of libuv - again a performance improvement.

The decision of webviews and electron is based on what you're trying to do. If it's simple html/JS that's pretty much self contained then sure.

It's been a minute since I attempted it on Windows, but transparency of borders and borderless windows with the webview on Windows was next to impossible. It's one of the reasons we used Electron. I'm curious to know if they've solved that, but can't find my mention of it.

This kind of makes me think... is there room for a much more stripped down version of Chromium that is suitable for lower memory footprint? Or is this impossible?

It looks like Tauri uses system webviews, which use a lot less memory, but the burden is then on the developer to make sure that they build essentially 3 (maybe more) UI's on platforms that might change under their feet. That's why the Electron approach is simpler - it trades of performance for uniformity of experience across the major platforms.

But I'm wondering if it really has to be this way. Do modern browsers really need 2G of RAM in order to send and receive messages in a chat box (looking at you, Slack).

I like Sciter for the possibilities, but it needs better compatibility with web standards. Being able to port an existing application that uses React -for example- and have it just run would be the cat's meow.

Needing to rewrite with other UI/JS frameworks to account for quirks gives me pause.

7 hours ago by c-smile

It depends on what application you have in mind.

React needs web browser compatibility layer to work in Sciter.JS as React was designed strictly for browsers.

For that matter: PReact ( https://preactjs.com/ ) works out of the box already, see : https://github.com/c-smile/sciter-js-sdk/tree/main/samples/p... ;

MithrilJS ( https://mithril.js.org/ ) works as it is also.

SvelteJS works as it is with Sciter.JS too.

Also Sciter.JS has its own native implementation of JSX ( it's built in JS core of Sciter.JS) and also DOM extended by native element.patch(vdom) that makes "reactivity" to work in Sciter.JS with native speed.

Yet quite a lot of UI components are natively built-in. For example:

Is this really different from the current state of web development? Front-end developers have to test against Chrome, Firefox, and Safari, at a minimum.

Do many companies actually do this though? I've only ever been with companies that test against Chrome. The one time at FF bug was found, that company told that client to switch to Chrome.

I know there was a kerfuffle about Airbnb and Groupon only doing Chrome as well.

Honestly I could try to ignore the memory consumption if at least it was snappy. The few electron apps I use have visible lag when I do something that forces a large redraw.

That's a problem that didn't have with GTK app running on a computer with one order of magnitude less computing power and RAM two decades ago. VS code on the first computer I used to program would probably be unusable (if it even launched), yet we had full fledged IDEs back then. I'm not talking about advanced language server plugins here, just basic usage.

The great side effect of this is that if you avoid all this wasteful crap and keep using old school technology, computers are snappier than ever. My terminal always pops up instantly, nvim fires up faster than I can press return, rg lets me search a huge codebase with barely noticeable latency. My IMAP mail client is faster, more configurable and more ergonomic than any webmail I've seen.

Life is good when you avoid the www.

It isn't your fault that you have to do this, it is that our industry hasn't created enough quality, easy to use, cross platform gui libraries for popular languages, such that the only viable place to turn is to use a whole web browser.

We've had about 60 years and multiple huge attempts at it, and IMHO HTML & CSS _are_ the easy to use cross-platform GUI platform. Nothing else stuck--flash, java swing, qt, etc. were all super capable and promising but failed to gain mass usage. HTML & CSS is the way. Nothing in existence has as much capability, developer usage and talent pool, accessibility and internationalization features, etc. A good GUI system is much more than just getting boxes and text on the screen.

I don't think this is entirely true. Have you tried wxWidgets or even Qt?

In my experience, this is more about resources and economics ("reuse existing code" vs. having to learn something new).

Oh if only that was enough. My Safari is currently using 25.33GB¹ and and it regularly goes over 30.

> 1TB SSDs cost less than $100

Ah, if only it was that easy.

¹ (According to iStat Menus; it's harder to see in Activity Monitor due to the separate processes.)

you can't buy an M1 mac with more than 16GB of memory so it seems like you have bigger problems

16GBs of memory isn’t enough for me anymore.[1] Although that is mostly due to Intellij and the Web at large (my browser).
