openPath opens Explorer twice

[Silbad]

Hi,

Windows + Tauri (latest) + Svelte 5

My code :

<script lang="ts">
  import { FolderCog } from "@lucide/svelte";
  import { appDataDir } from "@tauri-apps/api/path";
  import { openPath } from "@tauri-apps/plugin-opener";
  import { Button } from "$lib/components/ui/button/index.js";

  const openUserFolder = async () => {
    const appDataPath = await appDataDir();
    try {
      await openPath(
        `${appDataPath}/myapp${import.meta.env.DEV ? ".dev" : ""}`
      );
    } catch (error) {
      console.error("Error opening user folder:", error);
    }
  };
</script>

<Button
  variant="outline"
  size="icon"
  class="cursor-pointer size-10"
  onclick={openUserFolder}
  title="Open User Folder"
>
  <FolderCog />
</Button>

The behavior is strange. At first, a window opens instantly to “Documents,” then 5 seconds later, the window to the user's folder opens correctly. How can this be fixed? Is it due to Svelte (reactivity)?

I update all dependencies, same issue.

Okay, I think I understand the problem. I just wanted to open the folder, not the file. Opener only seems to work with files. Is that correct? Should I use shell instead?

Opener only seems to work with files. Is that correct?

Opener should work for both files and folders

I think I could reproduce your problem... So ${appDataPath}/myapp${import.meta.env.DEV ? ".dev" : ""} itself resolves to something like C:\Users\SomeUser\AppData\Roaming\some-app/myapp, and the mix use of slashes is causing the problem

I feel like this is a use case we should support but for now, use

const appDataPath = await appDataDir()
await join(appDataPath, 'myapp')

instead

At first, a window opens instantly to “Documents,” then 5 seconds later, the window to the user's folder opens correctly.

And about this behavior, from using a debugger, it seems like it hit

However, I should note that SHOpenFolderAndSelectItems in some cases, instead of returning an error, it falls back to opening a default directory which is usually the Documents folder
Byron/open-rs#107

And then the ShellExecuteExW fallback

Hi,
Opener 5.3.3 fix the issue. Perfect !
Thanks
