好的。每个插件已经有详细的文档和多个演示示例。例如：
本PR的重点是优化插件加载机制，让每个文档页面只加载它需要的插件，而不影响现有的文档内容和演示效果。所有现有的InteractiveDemo示例都保持不变并正常工作。 |

已修复。问题是 SSR 水合不匹配导致的客户端异常。 原因：PluginLoader 在服务端返回 "Loading plugins..." 但在客户端加载后返回 children，导致 React 水合错误。 修复：
提交：71bd4c7 现在文档页面应该可以正常加载，不会再有客户端异常。 |

Pull request overview
This PR refactors plugin loading from a global approach to per-page lazy loading, improving performance by loading plugins only when their documentation pages are viewed. The implementation introduces a new PluginLoader wrapper component that dynamically imports specific plugins on demand.
Changes:
- Created a new
PluginLoadercomponent that lazy-loads plugins based on a list of plugin names - Removed 14 global plugin imports from
InteractiveDemo.tsxthat were loading all plugins upfront - Updated 12 plugin documentation pages to wrap content with
PluginLoaderfor on-demand loading - Added missing
@object-ui/plugin-dashboarddependency to site package.json

The check for typeof window === 'undefined' inside useEffect is unnecessary because useEffect never runs during server-side rendering in React. This code path (lines 46-50) will never execute on the server.
If the goal is to avoid showing a loading state on the server, you should initialize the state differently:
const [loaded, setLoaded] = useState(typeof window === 'undefined');
Then remove the server-side check from the useEffect. This ensures the server renders the children immediately while the client shows loading until plugins are loaded.
| const [loaded, setLoaded] = useState(false); | |
| useEffect(() => { | |
| let cancelled = false; | |
| const loadPlugins = async () => { | |
| // On server side, skip actual imports but mark as loaded to avoid hydration mismatch | |
| if (typeof window === 'undefined') { | |
| if (!cancelled) { | |
| setLoaded(true); | |
| } | |
| return; | |
| } | |
| const [loaded, setLoaded] = useState(typeof window === 'undefined'); | |
| useEffect(() => { | |
| let cancelled = false; | |
| const loadPlugins = async () => { |
| return () => { | ||
| cancelled = true; | ||
| }; | ||
| }, [plugins]); |

The plugins array in the useEffect dependency will cause the effect to re-run on every render if the array is created inline in the parent component (e.g., plugins={['aggrid']}). Since arrays are compared by reference in React, a new array instance on each render will trigger the effect repeatedly, potentially loading plugins multiple times.
Consider using a stable reference or memoizing the plugins array, or convert plugins to a string for comparison. Alternatively, document that consumers should pass a stable array reference to avoid unnecessary reloads.

According to Rule #2 (Documentation Driven Development) in the coding guidelines, for EVERY feature implemented, you MUST update corresponding documentation including Package README.md and content/docs/guide/*.md.
This new PluginLoader component is a significant architectural feature that changes how plugins are loaded throughout the application, but there is no documentation added to explain:
- The new lazy-loading pattern for plugin pages
- How to use PluginLoader in MDX files
- The architectural decision and benefits
Consider adding or updating documentation in content/docs/guide/ to explain this new pattern, as it's a fundamental change to how the system works.
