bundler: Webview2 installation options not respected

[heyrict]

Problem

Webview2 offline installer was not bundled in the msi or nsis installation package even if bundle.windows.webview_install_mode was set to OfflineInstaller or FixedVersion.

Steps To Reproduce

The reproducible sample was put in https://github.com/heyrict/dioxus-bundle-sample

The build binaries from github action were only ~3MB each.

Expected behavior

The built binary should include webview2 installer (expected to be ~130MB).

Environment:

• Dioxus version: 0.4.0
• Rust version: nightly
• OS info: Windows
• App platform: desktop

Questionnaire

• [ ] I'm interested in fixing this myself but don't know where to start
• [ ] I would like to fix and I have a solution
• [x] I don't have time to fix this right now, but maybe later

I'm facing the same issue, but in addition I also tried "FixedRuntime" with a path (note: I think this topic could use some improvements in the docs, but that might be more of a topic in #87). I've tried installing the resulting msi or nsis bundle, but when starting the application afterward, it comes up with the error "Code execution cannot proceed because WebView2Loader.dll was not found. [...]"

Environment:

Dioxus version: 0.4.0 Rust version: 1.71.1 stable-x86_64-pc-windows-gnu OS info: Windows App platform: desktop

If I can be of any help in resolving this, I'm happy to do so. Any help would be greatly appreciated.

Yes, we definitely need to improve the documentation around bundling

Rust version: 1.71.1 stable-x86_64-pc-windows-gnu

We have found in the past that windows-gnu tends to have more issues with tauri than windows msvc.

If I can be of any help in resolving this, I'm happy to do so. Any help would be greatly appreciated.

There are a few different things we can try here:

1. Bumping tauri-bundle. The latest version is 2.0.0-alpha-7, but we are using an older stable version. I did find several issues in the tauri repo related to offline bundling, but none looked exactly like this.
2. Comparing a working tauri bundle config with offline installation with a failing Dioxus.toml config. We convert our format to the tauri-bundle struct here. We could be setting some configs differently from what tauri would set.

As per mentioned by @ealmloff , I've tried updating tauri-bundler to the latest and debug printing the converted tauri_bundler::BundleSettings, without any findings.

~~Correct me if I was wrong, but after a bit dig into the code base of tauri_bundler, it seems that FixedRuntime was not currently implemented even in taori itself. OfflineInstaller should work anyway. And after a brief search on github, there do exist some tauri applications that use this config to bundle their applications.~~

~~When I went through the code of tauri_bundler, I've noticed that the nsis packager will skip the webview2 section if it found that webview2 was installed. I have no knowledge on nsis and am not sure if this is related to the fact the webview installer was not bundled, but probably it is worth some testing.~~

Rectification: It seems that tauri copies some resources regarding Webview2 in tauri_build, thus running merely tauri_bundler::bundle::bundle_project was not enough.
