Task: Move Plugin Imports from Global to Per-Page ✅

Status: COMPLETE - All Issues Resolved

Completed Tasks

  • Understand current architecture and plugin loading mechanism
  • Create a new PluginLoader component for lazy-loading plugins per page
  • Update each plugin documentation page to import its specific plugin
  • Remove global plugin imports from InteractiveDemo.tsx
  • Add missing plugin-dashboard dependency to site package.json
  • Fix PluginLoader to use truly dynamic imports (switch-case in useEffect)
  • Fix code review issues (stray backtick, default case)
  • Fix SSR hydration mismatch causing client-side exception
  • Add cleanup function to prevent potential race conditions
  • Verify code quality with automated reviews

Latest Improvement: Cleanup Function

Added proper cleanup pattern to PluginLoader:

  • Introduced cancelled flag to track component unmount
  • Prevents setLoaded(true) from being called after component unmounts
  • Returns cleanup function that sets cancelled = true
  • Follows React best practices for async operations in useEffect

All Changes Summary

File: apps/site/app/components/PluginLoader.tsx (NEW)

  • Lazy-loads specific plugins on-demand
  • Proper SSR handling (no hydration mismatch)
  • Cleanup function prevents race conditions
  • Switch-case prevents bundler from including all plugins

File: apps/site/app/components/InteractiveDemo.tsx

  • Removed 14 global plugin imports
  • Removed plugin loading state management
  • Simplified to render SchemaRenderer directly

Files: 12 plugin documentation pages

  • Wrapped content with <PluginLoader plugins={['plugin-name']}>
  • Each page loads only its required plugin

File: apps/site/package.json

  • Added missing @object-ui/plugin-dashboard dependency

Benefits

Performance: Plugins load only when needed
Bundle Size: 14 fewer global imports
SSR Compatible: No hydration mismatches
Race Condition Safe: Proper cleanup on unmount
Type Safe: TypeScript compilation ready

Original prompt

应该在对应的文档演示页引入插件代码和样式,而不应该在demo控件全局引入。

@copilot 应该为每一个插件编写文档并精心设计演示效果

好的。每个插件已经有详细的文档和多个演示示例。例如:

  • plugin-aggrid.mdx: 648行,包含15+个交互示例
  • plugin-charts.mdx: 348行,多种图表类型演示
  • plugin-calendar.mdx: 518行,多个日历用例

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。

@copilot Application error: a client-side exception has occurred while loading objectui-site-fth5d44do-object-stack.vercel.app (see the browser console for more information).

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

  1. 在服务端也设置 loaded = true,确保服务端和客户端渲染一致
  2. 添加清理函数防止组件卸载后的状态更新

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 PluginLoader component that lazy-loads plugins based on a list of plugin names
  • Removed 14 global plugin imports from InteractiveDemo.tsx that were loading all plugins upfront
  • Updated 12 plugin documentation pages to wrap content with PluginLoader for on-demand loading
  • Added missing @object-ui/plugin-dashboard dependency 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.

Suggested change
const[loaded,setLoaded]=useState(false);
useEffect(()=>{
letcancelled=false;
constloadPlugins=async()=>{
// On server side, skip actual imports but mark as loaded to avoid hydration mismatch
if(typeofwindow==='undefined'){
if(!cancelled){
setLoaded(true);
}
return;
}
const[loaded,setLoaded]=useState(typeofwindow==='undefined');
useEffect(()=>{
letcancelled=false;
constloadPlugins=async()=>{

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:

  1. The new lazy-loading pattern for plugin pages
  2. How to use PluginLoader in MDX files
  3. 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.
