this is working really well!

see the cargo-mobile2 integration and the tauri branch

can we call https://docs.openharmony.cn/pages/v5.0/en/application-dev/reference/apis-arkweb/js-apis-webview.md#setwebdebuggingaccess when webview_attributes.devtools is true? I'm trying to debug a localhost usage, currently only remote URLs are working on tauri

Could you try those changes in your local code which is in root/oh_modules/.ohpm/@ohos-rs+abilityxxx/xx ? @lucasfernog

If it works, i will publish a new version for @ohos-rs/ability

are the javaScriptOnDocumentStart scripts executed out of order? i'm seeing some weird behavior, is it running in reverse order?
for now i think i'll just combine all scripts into one.. but would be good to know exactly how the webview runs them

richerfu · 2025-08-20T14:10:03Z

javaScriptOnDocumentStart

I need to check it. May i tell you later..

lucasfernog · 2025-08-20T14:16:06Z

also can't we really register the custom protocols at runtime? currently we need to provide the names beforehand on the derive macro right?

yeah,we need to register the custom protocols in a very early stage. When we need to register them at runtime, i can try to find some ways to support it

lucasfernog · 2025-08-20T15:53:00Z

is the custom protocol triggered on fetch() calls? tauri uses that for the IPC

for instance this is what i get:

await fetch('tauri://localhost')
VM174:1 Fetch API cannot load tauri://localhost/. URL scheme "tauri" is not supported.

even though the page loaded is tauri://localhost

cool that's fine, thanks

this lets the custom protocol to return its response on a separate thread or async task, rather than relying on the return value of the callback needed by tauri-apps/wry#1607

It run with lexicographic order.If we want to run them with array order, we need to use runJavaScriptOnDocumentStart , but it depends on api15 or newer. It's too new for us.

In what scenarios will we register at runtime? From the documentation, it is clear that the protocol can only be registered before the web is initialized. There is no any other method to register :(

Hi @lucasfernog dear friend, if we want to continue this work, what we should do. Hope your reply thanks :)

FabianLars · 2025-09-18T04:28:34Z

Just so you're not surprised, Lucas is on vacation (or at least out of office) for another week or so.
I think work on this from our side will slow down though because our task at our workplace, which made us look into it in the first place, is done.

richerfu · 2025-09-18T06:44:51Z

Copy that, hope you have a good time. :)
