Description

When using the devtool panels (ReactQueryDevtoolsPanel, PreactQueryDevtoolsPanel, etc.) inside the TanStack Devtools plugin workspace, the panel has a hardcoded height of 500px, which prevents it from filling the available container height.

Changes

Changed the default panel style from a fixed height: 500px to height: 100% with minHeight: 500px:

  • React (ReactQueryDevtoolsPanel.tsx): height: 500pxheight: 100%, minHeight: 500px
  • Preact (PreactQueryDevtoolsPanel.tsx): same change
  • Solid (devtoolsPanel.tsx): same change
  • Vue (devtoolsPanel.vue): same change

This ensures:

  1. The panel fills its container when used inside TanStack Devtools plugin workspace
  2. The panel has a reasonable minimum height (500px) when used standalone

Fixes #11182

Summary by CodeRabbit

  • Improvements
    • Devtools panels now expand to fill the available vertical space while maintaining a minimum height of 500px.
    • Provides a more flexible and consistent layout across supported frameworks.

Change the default height of devtool panels from a fixed 500px to
height: 100% with minHeight: 500px. This ensures the panel fills
its container when used inside TanStack Devtools plugin workspace,
while still having a reasonable minimum height when used standalone.

Fixes TanStack#11182

📝 Walkthrough

Walkthrough

Devtools panels in the React, Solid, Preact, and Vue adapters now use height: '100%' with minHeight: '500px'. React and Solid option documentation matches the rendered styles.

Changes

Panel height alignment

Layer / File(s) Summary
Update panel height styles
packages/*-query-devtools/src/*
The React, Solid, Preact, and Vue panels now fill the available height while retaining a 500px minimum. Custom style overrides remain supported. React and Solid style documentation reflects the new defaults.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: 🟡 Moderate · up to ce9f8

The panel now uses the container height with a 500px minimum, but a Preact test still expects the removed fixed 500px behavior. Update that test before merging so the suite validates the new contract.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Update the stale Preact panel test.

packages/preact-query-devtools/src/__tests__/PreactQueryDevtoolsPanel.test.tsx:146-158 still expects height: '500px'. This code now renders height: '100%' and minHeight: '500px', so the test will fail. Assert the new height and minimum height.
