How use react-query mutations with axios?

Using Axios for data mutation operations within React Query is a common practice. React Query simplifies and efficiently integrates Axios by providing the useMutation hook. Below, I will provide a detailed explanation of how to use Axios within React Query mutations, along with a concrete example.

Step 1: Install the Necessary Libraries

First, ensure your project has already installed react-query and axios. If not, you can install them using the following command:

bash
npm install react-query axios

Step 2: Create Axios Requests

Suppose we need to add a user via a POST request. We can create a function to handle this request:

javascript
import axios from 'axios';

const addUser = async (user) => {
  const response = await axios.post('/api/users', user);
  return response.data;
};

In this function, user is an object containing the user information to be sent to the server.

Step 3: Use the useMutation Hook

In your component, you can utilize the useMutation hook to use the addUser function created above. This hook allows us to conveniently handle loading states, error states, and data updates.

javascript
import { useMutation } from 'react-query';

function CreateUserComponent() {
  const mutation = useMutation(addUser, {
    onSuccess: () => {
      // Handle success scenario
      console.log('User added successfully!');
    },
    onError: (error) => {
      // Handle error scenario
      console.error('Error adding user:', error);
    }
  });

  const handleSubmit = (user) => {
    mutation.mutate(user);
  };

  return (
    <form onSubmit={(e) => {
      e.preventDefault();
      const user = { name: 'John', age: 30 };
      handleSubmit(user);
    }}>
      <button type="submit">Add User</button>
    </form>
  );
}

In this component, we create a form where submitting the form triggers the handleSubmit function. This function calls mutation.mutate(user) to execute the mutation operation. We also define onSuccess and onError callbacks to handle the logic after the operation succeeds or fails.

Summary

Through the above steps, we can see that integrating Axios into React Query for mutations is straightforward and efficient. By leveraging the useMutation hook, we can concisely handle various states of asynchronous requests, making the code clearer and more maintainable. This pattern is particularly suitable for handling data mutation operations that require interaction with the server.

Using Axios in React Query mutations is a common pattern for handling asynchronous data updates in React components. Here's a step-by-step guide on how to use Axios within the useMutation hook of React Query.

Step 1: Install Required Dependencies

First, ensure you have installed react-query and axios.

bash
npm install react-query axios

Step 2: Set Up Axios Requests

You need to create an Axios request to handle operations that modify data via mutations, such as POST, PUT, PATCH, or DELETE requests.

javascript
import axios from 'axios';

const updateData = async (dataToUpdate) => {
  const { data } = await axios.put('/api/data', dataToUpdate);
  return data;
};

Step 3: Use the useMutation Hook in Components

Within your React component, you can use the useMutation hook to invoke the previously created updateData function. useMutation allows you to define callbacks for success, error, and other triggered events.

javascript
import { useMutation } from 'react-query';

const MyComponent = () => {
  const mutation = useMutation(updateData, {
    onSuccess: (data) => {
      // Handle success case
      console.log('Data updated successfully:', data);
    },
    onError: (error) => {
      // Handle error case
      console.error('Error updating data:', error);
    },
    onSettled: (data, error) => {
      // Called regardless of success or failure
      if (error) {
        console.error('Error after mutation:', error);
      } else {
        console.log('Mutation settled with data:', data);
      }
    },
  });

  const handleSubmit = async (event) => {
    event.preventDefault();
    const formData = {
      // Get data from form or component state
    };

    mutation.mutate(formData);
  };

  return (
    <form onSubmit={handleSubmit}>
      {/* Form content */}
      <button type="submit">Submit</button>
    </form>
  );
};

Example Explanation

In the example above, updateData is an asynchronous function that updates data by calling the backend API via Axios. Within the component, the useMutation hook creates a mutation instance by passing the updateData function and related callbacks.

When the user submits the form, the handleSubmit function is triggered, passing the form data to mutation.mutate, which executes updateData. The callbacks provided by useMutation enable you to respond to the mutation result, such as updating the UI or handling errors.
