graphql-error-boundaries

graphql-error-boundaries is a cursor rule for Cursor from holtwood/awesome-cursorrules-zh. It costs 0 tokens per session (608 once invoked), scanned A, original, MIT.

A React error-handling rule for GraphQL operations. An error boundary is a component that shows fallback content when part of the interface crashes.

In plain words
What is it for?
Use it to show fallback UI, offer retry actions, and send captured errors to monitoring services such as Sentry or Bugsnag.
Why use it?
It stops a GraphQL-related component error from taking down the whole application and gives users a clear recovery path.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

graphql-error-boundaries scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 7d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

  • 为 GraphQL 错误实现适当的错误边界
    • 使用 React 错误边界:利用 React 的错误边界(Error Boundaries)来捕获组件树中由 GraphQL 操作(查询、变更、订阅)引起的 JavaScript 错误,防止整个应用崩溃。
    • 集中错误处理:在错误边界组件中集中处理和展示友好的错误信息,而不是让每个组件单独处理错误状态。
    • 错误日志记录:在错误边界中实现错误日志记录机制(例如,发送到 Sentry、Bugsnag 等错误监控服务),以便于跟踪和诊断生产环境中的问题。
    • 用户体验:当发生错误时,向用户显示一个回退 UI,提供重试选项或引导用户进行下一步操作,提升用户体验。
    • 示例
      // ErrorBoundary.js
      import React from 'react';
      
      class ErrorBoundary extends React.Component {
        constructor(props) {
          super(props);
          this.state = { hasError: false, error: null, errorInfo: null };
        }
      
        static getDerivedStateFromError(error) {
          // 更新 state 使下一次渲染能够显示降级后的 UI
          return { hasError: true };
        }
      
        componentDidCatch(error, errorInfo) {
          // 你同样可以将错误日志上报给服务器
          console.error("Uncaught error:", error, errorInfo);
          this.setState({ error, errorInfo });
        }
      
        render() {
          if (this.state.hasError) {
            // 你可以自定义降级后的 UI 并渲染
            return (
              <div style={{ padding: '20px', border: '1px solid red', color: 'red' }}>
                <h2>Something went wrong.</h2>
                <details style={{ whiteSpace: 'pre-wrap' }}>
                  {this.state.error && this.state.error.toString()}
                  <br />
                  {this.state.errorInfo.componentStack}
                </details>
              </div>
            );
          }
      
          return this.props.children;
        }
      }
      
      export default ErrorBoundary;
      
      // 在应用中使用
      // <ErrorBoundary>
      //   <MyGraphQLComponent />
      // </ErrorBoundary>
      
    • 与 Apollo Link 结合:对于 GraphQL 网络层面的错误(如 HTTP 错误、GraphQL 格式错误),可以结合 Apollo Client 的 ErrorLink 进行处理,并在 ErrorLink 中抛出错误,使其能被 React 错误边界捕获。

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
