npm install react-query-database-plugin

# 或者

yarn add react-query-database-plugin

import { QueryClient, QueryClientProvider } from 'react-query';
import { createDatabasePlugin } from 'react-query-database-plugin';

const queryClient = new QueryClient({
  // 其他配置项
  plugins: [
    // 添加数据库插件
    createDatabasePlugin({
      // 配置数据库连接
      // 这里可以使用的容器编排工具的环境变量
      connection: process.env.DATABASE_URL,
    }),
  ],
});

  <QueryClientProvider client={queryClient}>
    <App />
  </QueryClientProvider>,
  document.getElementById('root')
