React Query 数据库插件：与监控和告警系统的集成实践

// react-query-database-plugin.js

import { QueryCache } from "react-query";
import { queryClient } from "./queryClient";
import { initMonitoring } from "./monitoring";

export const reactQueryDatabasePlugin = (monitoringConfig) => {
  // 初始化 React Query
  const queryCache = new QueryCache();
  const queryClient = new QueryClient({ queryCache });

  // 初始化监控和告警系统
  const monitoring = initMonitoring(monitoringConfig);

  // 监听 React Query 的请求和响应
  queryClient.onQueryStart(({ queryKey }) => {
    monitoring.startRequest(queryKey);
  });

  queryClient.onQuerySuccess(({ queryKey, data }) => {
    monitoring.endRequest(queryKey);
    monitoring.logSuccess(queryKey, data);
  });

  queryClient.onQueryError(({ queryKey, error }) => {
    monitoring.endRequest(queryKey);
    monitoring.logError(queryKey, error);
  });

  return queryClient;
};

// app.js

import { QueryClientProvider } from "react-query";
import { reactQueryDatabasePlugin } from "react-query-database-plugin";

const monitoringConfig = {
  // 配置监控和告警的参数
};

const queryClient = reactQueryDatabasePlugin(monitoringConfig);

function App() {
  return (
    <QueryClientProvider client={queryClient}>
      {/* 应用程序主体代码 */}
    </QueryClientProvider>
  );
}

// example.js

import { useQuery } from "react-query";

function ExampleComponent() {
  const { data, isLoading, error } = useQuery("exampleKey", () =>
    fetch("https://api.example.com/data").then((response) => response.json())
  );

  if (isLoading) {
    return <div>Loading...</div>;
  }

  if (error) {
    return <div>Error: {error.message}</div>;
  }

  return <div>Data: {JSON.stringify(data)}</div>;
}
