Building a browser.

[MBoui]

Hi the community,

I like Tauri, and i want to use him everywhere! I think to start a new project which will be a little web browser.
I am really curious about what do you think to start this kind of project with Tauri? Do you see any limitation or concern for this kind of project?

[JonasKruckenberg]

Without wanting to hurt your feelings: Don't.

here's a bit about why

Essentially building a browser is very different from building a webview UI where the source is trusted.
Enabling this on our end will require significant effort to get right, something that we cannot handle.

Building a browser also requires a lot more effort on your end than you might imagine. A browser is almost on-par with operating systems when it comes to complexity.

Interestingly enough electron and Tauri are on the same page here. Executing untrusted content in either framework is incredibly insecure and highly, highly, highly discouraged.

Edit: If you want to build a Browser, you're much better off doing what Brave or Edge did and use the CEF (chromium embedded framework) directly

I like your answer, but what if I don't want to use chromium but tauri engine ?

Wouldn't it then be Webview2 on Windows, and Webview2 is a highly modified fork of chromium.

FWIW, the issue @JonasKruckenberg linked above, #2975 , has been fixed a few months ago.

Where do Electron devs say that ?

FWIW, BonBon Browser project is built on top of Electron.

Brave and Edge both build on forked Chromium, but neither use CEF.

Well it's even easier to use cef when building your own browser

Firefox . . . Would it be possible i mean they have no equivalent to electron witch i find weird but it could be a option but its a very complex project i bet

Sadly Firefox does not have a webview for desktop platforms. Which makes it virtually impossible, because you'd need to fork it and maintain it.

Is it possible to just load a website that is specified to load via tauri?

[mahadi-hossain]

You can build but you know turi does not provide so many functionalities. I always struggle with dilatory launching speed of established browsers. So I decided to build a very light and blazing first one by using tauri, in this case security does not matter for my personal use

Did someone created yet?

[nileshtrivedi]

I built a very rough POC in case anybody is interested. I don't want to invest too much time into it until multiwebview becomes a stable feature or unless some one pitches in for help.

EDIT: I have pushed my code example in the osdemo branch here: https://github.com/nileshtrivedi/tauri/tree/osdemo

This is added as a new example here. It can be run with from the top directory of the repo with cargo run --example osdemo --features unstable

It's rough because the main webview is a single webpage index.html using TailwindCSS and DaisyUI via CDN with imperative Javascript code for adding/listing/removing webviews, whereas for a real-app I'd like to use some kind of component framework like Svelte or Preact.

Also, the webview size and placement is currently random. Also I have not yet figured out how to add window border and decoration because the webviews positioning is done in Rust but without any border. DaisyUI has a mock browser component but the size/position of webviews in Rust is with respect to the whole window/screen which is tricky to communicate and handle inside the main webview.

Hi,

Could you please share the code in a repo ?

until multiwebview becomes a stable feature

The feature was shipped in v2.0.0, right ?

[autonome]

Folks in the User & Agents community are poking at similar directions, you'd likely get interest if there was a repo w/ example code.
