useUpdateMany initalised many times across parameter fields

There seems to be a cost of initialisingthe the useUpdateMany hook which is only really noticable when say over fifty times in a view in a table

Hi @Joe Gaffney. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- The useUpdateMany hook in Refine is designed to handle the process of updating multiple records at once. However, if you are initializing this hook many times (e.g., over fifty times) within a single view, it can indeed lead to performance issues due to the overhead of multiple hook initializations. To mitigate this, you should consider the following strategies: 1. Batch Updates: Instead of initializing useUpdateMany multiple times, try to batch your updates. You can collect the changes and then call mutate once with all the necessary updates. 2. Optimize Hook Usage: Ensure that you are not unnecessarily re-initializing the hook. Place the hook initialization at a higher level in your component hierarchy if possible, and pass down the mutate function to child components. 3. Memoization: Use memoization techniques to avoid re-initializing hooks unnecessarily. React's useMemo or useCallback can be helpful here. Here is an example of how you might use the useUpdateMany hook efficiently:

import { useUpdateMany } from "@refinedev/core";  

const MyComponent = () => {
  const { mutate } = useUpdateMany();

  const handleBatchUpdate = (updates) => {
    mutate({
      resource: "products",
      values: updates.values,
      ids: updates.ids,
    });
  };

  // Collect updates and call handleBatchUpdate when needed
  // ...

  return (
    // Your component JSX
  );
};

import { useUpdateMany } from "@refinedev/core";  

const MyComponent = () => {
  const { mutate } = useUpdateMany();

  const handleBatchUpdate = (updates) => {
    mutate({
      resource: "products",
      values: updates.values,
      ids: updates.ids,
    });
  };

  // Collect updates and call handleBatchUpdate when needed
  // ...

  return (
    // Your component JSX
  );
};

For more detailed information on how to use the useUpdateMany hook, you can refer to the Refine documentation (https://refine.dev/docs/data/hooks/use-update-many/). If you need to see an example in action, you can try the example provided in the Refine repository: - Material-UI Example (https://github.com/refinedev/refine/tree/master/examples/table-material-ui-use-update-many) - Ant Design Example (https://github.com/refinedev/refine/tree/master/examples/table-antd-use-update-many) You can also run these examples locally using the following commands:

npm create refine-app@latest -- --example table-material-ui-use-update-many

npm create refine-app@latest -- --example table-material-ui-use-update-many

npm create refine-app@latest -- --example table-antd-use-update-many

npm create refine-app@latest -- --example table-antd-use-update-many

By following these strategies, you should be able to reduce the performance overhead associated with initializing the useUpdateMany hook multiple times. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai they are eseenitally unique feilds that have there own updates inside the table. Its not the performance when calling the mutate method just of initliazing the hook

kapa.ai•6mo ago

Let me check the knowledge base for you. One moment! :books: ---------------------- If you have unique fields that require their own updates inside a table and the performance issue arises from initializing the useUpdateMany hook multiple times, you can consider the following strategies to optimize the initialization process: 1. Single Hook Initialization: Initialize the useUpdateMany hook once and manage the updates through a centralized function. This way, you avoid the overhead of multiple hook initializations. 2. Context or State Management: Use React's context or state management libraries (like Redux) to manage the updates. This allows you to initialize the hook once and dispatch updates as needed. Here is an example of how you might initialize the useUpdateMany hook once and manage updates through a centralized function:

import { useUpdateMany } from "@refinedev/core";  
import React, { useState } from "react";

const MyComponent = () => {
  const { mutate } = useUpdateMany();
  const [updates, setUpdates] = useState([]);

  const handleUpdate = (id, values) => {
    setUpdates((prevUpdates) => [...prevUpdates, { id, values }]);
  };

  const applyUpdates = () => {
    const ids = updates.map(update => update.id);
    const values = updates.reduce((acc, update) => {
      acc[update.id] = update.values;
      return acc;
    }, {});

    mutate({
      resource: "products",
      values,
      ids,
    });
  };

  return (
    <div>
      {/* Your table and fields */}
      <button onClick={applyUpdates}>Apply Updates</button>
    </div>
  );
};

import { useUpdateMany } from "@refinedev/core";  
import React, { useState } from "react";

const MyComponent = () => {
  const { mutate } = useUpdateMany();
  const [updates, setUpdates] = useState([]);

  const handleUpdate = (id, values) => {
    setUpdates((prevUpdates) => [...prevUpdates, { id, values }]);
  };

  const applyUpdates = () => {
    const ids = updates.map(update => update.id);
    const values = updates.reduce((acc, update) => {
      acc[update.id] = update.values;
      return acc;
    }, {});

    mutate({
      resource: "products",
      values,
      ids,
    });
  };

  return (
    <div>
      {/* Your table and fields */}
      <button onClick={applyUpdates}>Apply Updates</button>
    </div>
  );
};

In this example: - The useUpdateMany hook is initialized once. - Updates are collected in the updates state. - The handleUpdate function is used to collect updates for each unique field. - The applyUpdates function is used to batch and apply all collected updates at once. For more detailed information on how to use the useUpdateMany hook, you can refer to the Refine documentation (https://refine.dev/docs/data/hooks/use-update-many/).

@kapa.ai but if i put the update hook in a context would it not trigger all the components to re-render

kapa.ai•6mo ago

Let me check the knowledge base for you. One moment! :books: ---------------------- Using a context to manage the useUpdateMany hook can indeed lead to unnecessary re-renders if not handled properly. However, you can mitigate this by using memoization techniques and ensuring that the context value does not change unless necessary. Here’s how you can achieve this: 1. Create a Context: Create a context to provide the mutate function from the useUpdateMany hook. 2. Memoize the Context Value: Use useMemo to ensure the context value only changes when necessary. 3. Use the Context in Components: Consume the context in your components to access the mutate function without causing unnecessary re-renders. Here’s an example:

import React, { createContext, useContext, useMemo } from "react";
import { useUpdateMany } from "@refinedev/core";

// Create a context
const UpdateManyContext = createContext(null);

// Create a provider component
const UpdateManyProvider = ({ children }) => {
  const { mutate } = useUpdateMany();

  // Memoize the context value
  const contextValue = useMemo(() => ({ mutate }), [mutate]);

  return (
    <UpdateManyContext.Provider value={contextValue}>
      {children}
    </UpdateManyContext.Provider>
  );
};

// Custom hook to use the context
const useUpdateManyContext = () => {
  return useContext(UpdateManyContext);
};

// Example component consuming the context
const MyComponent = () => {
  const { mutate } = useUpdateManyContext();

  const handleUpdate = (id, values) => {
    mutate({
      resource: "products",
      values,
      ids: [id],
    });
  };

  return (
    <div>
      {/* Your table and fields */}
      <button onClick={() => handleUpdate(1, { name: "Updated Name" })}>
        Update
      </button>
    </div>
  );
};

// Usage
const App = () => (
  <UpdateManyProvider>
    <MyComponent />
    {/* Other components */}
  </UpdateManyProvider>
);
export default App;

import React, { createContext, useContext, useMemo } from "react";
import { useUpdateMany } from "@refinedev/core";

// Create a context
const UpdateManyContext = createContext(null);

// Create a provider component
const UpdateManyProvider = ({ children }) => {
  const { mutate } = useUpdateMany();

  // Memoize the context value
  const contextValue = useMemo(() => ({ mutate }), [mutate]);

  return (
    <UpdateManyContext.Provider value={contextValue}>
      {children}
    </UpdateManyContext.Provider>
  );
};

// Custom hook to use the context
const useUpdateManyContext = () => {
  return useContext(UpdateManyContext);
};

// Example component consuming the context
const MyComponent = () => {
  const { mutate } = useUpdateManyContext();

  const handleUpdate = (id, values) => {
    mutate({
      resource: "products",
      values,
      ids: [id],
    });
  };

  return (
    <div>
      {/* Your table and fields */}
      <button onClick={() => handleUpdate(1, { name: "Updated Name" })}>
        Update
      </button>
    </div>
  );
};

// Usage
const App = () => (
  <UpdateManyProvider>
    <MyComponent />
    {/* Other components */}
  </UpdateManyProvider>
);
export default App;

In this example: - The UpdateManyProvider initializes the useUpdateMany hook and provides the mutate function via context. - The contextValue is memoized using useMemo to prevent unnecessary re-renders. - The useUpdateManyContext custom hook is used to consume the context in MyComponent. By following this approach, you can ensure that the mutate function is accessible throughout your component tree without causing unnecessary re-renders. For more detailed information on how to use the useUpdateMany hook, you can refer to the Refine documentation (https://refine.dev/docs/data/hooks/use-update-many/). If you need to see an example in action, you can try the example provided in the Refine repository: - Material-UI Example (https://github.com/refinedev/refine/tree/master/examples/table-material-ui-use-update-many) - Ant Design Example (https://github.com/refinedev/refine/tree/master/examples/table-antd-use-update-many) You can also run these examples locally using the following commands:

npm create refine-app@latest -- --example table-antd-use-update-many

npm create refine-app@latest -- --example table-antd-use-update-many

By using context and memoization effectively, you can manage the useUpdateMany hook without causing unnecessary re-renders. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai is there anyway to reduce the overhead of initlising the useUpdateMany hook why is the cost high

kapa.ai•6mo ago

Let me check the knowledge base for you. One moment! :books: ---------------------- The overhead of initializing the useUpdateMany hook multiple times can be attributed to the internal workings of React hooks and the additional logic that useUpdateMany brings from Refine. Each initialization involves setting up state, context, and possibly side effects, which can accumulate and lead to performance issues when done excessively. To reduce the overhead, consider the following strategies: 1. Single Hook Initialization: Initialize the useUpdateMany hook once and manage updates through a centralized function. This avoids the repeated setup cost. 2. Memoization: Use React's useMemo or useCallback to memoize the hook's return values and functions, ensuring they are not recreated unnecessarily. 3. Context Management: Use React context to provide the mutate function to child components, ensuring the hook is only initialized once. Here’s an example of how you might initialize the useUpdateMany hook once and manage updates through a centralized function:

import { useUpdateMany } from "@refinedev/core";  
import React, { useState, useMemo, createContext, useContext } from "react";

// Create a context
const UpdateManyContext = createContext(null);

  const { mutate } = useUpdateMany();

  // Memoize the context value
  const contextValue = useMemo(() => ({ mutate }), [mutate]);

  return (
    <UpdateManyContext.Provider value={contextValue}>
      {children}
    </UpdateManyContext.Provider>

    });
  };

  return (
    <div>
      {/* Your table and fields */}
      <button onClick={() => handleUpdate(1, { name: "Updated Name" })}>
        Update
