UX Enhancements and Windows Build Fixes

[VentFiree]

Environment

Some minor user experience issues

I identified a few minor areas for improvement that could make the project even more polished

Issue description

Description: Currently, the login interface requires a manual click on the "Login" button. Standard UX expects the form to submit upon pressing the "Enter" key.
Proposed Fix: Wrap the input components in a form element or add an onKeyDown listener to trigger the login function.

Description: The test file pkg/common/util/os/limits_test.go uses golang.org/x/sys/unix, which causes build failures on Windows because unix.Rlimit and unix.Getrlimit are not defined in the Windows environment.
Proposed Fix: Use build tags (e.g., //go:build !windows) to exclude this test from Windows builds, or implement a mock for the Windows platform.

UX Tweaks: Improving the login flow by adding default cursor focus and 'Enter' key submission.
Cross-platform Support: Fixing a Windows-specific build error in limits_test.go.

Hi @VentFiree

I'd like to work on both parts of this issue as part of my GSoC 2026 preparation.

My Background

• I'm currently working on Windows build improvements (see PR docs: add Windows build instructions #1408)
• I have a Windows 11 environment with Go 1.24.6 and Node 24.13.0
• I've successfully built both frontend and backend on Windows

Update: ICLA Confirmed ✅

Good news - my Apache ICLA was confirmed by the Apache Secretary on Feb 5, 2026. Once this PR gets reviewed, it should be good to merge!

I've tested both fixes thoroughly

Login UX improvements
Testing environment: Windows 11, Chrome and Edge browsers

I tested the Enter key functionality and auto-focus feature:

• Username field gets focus automatically when the page loads ✓
• Pressing Enter in the username field submits the form (I verified this by checking the Network tab in DevTools - it's making the API call to /api/v1/auth/login)
• Same thing happens when you press Enter in the password field ✓
• The Login button still works normally when clicked ✓
• No JavaScript errors in the console ✓

Windows build fix
Testing environment: Windows 11, Go 1.24.6

Before my changes, trying to build on Windows would fail with:

golang.org/x/sys/unix: package not available on windows

After adding the build tags to limits_test.go, the build completes successfully:

PS> go build -o bin\dubbo-admin.exe .
 Builds without errors now

The binary gets created and everything works as expected.

What I changed

For the login form, I used Ant Design Vue's @pressEnter event (which is part of their official API) and Vue 3's ref and onMounted hooks for the auto-focus feature.

For the Windows build issue, I added Go build tags to exclude the Unix-specific test file from Windows builds. This follows the same pattern already used in limits.go in the same directory.

Next steps

I'm preparing the PR now and will link it here once it's ready.

Happy to address any feedback or questions! Thanks for reviewing.

Hey! I just opened a PR for this: #1409

I tested both fixes on my Windows 11 machine and they're working well:

• The login form now submits when you press Enter (and the username field gets focus automatically)
• The Windows build works now - I added build tags to exclude the Unix-specific test file

Let me know if you have any questions or want me to change anything!
