Interceptors

Axios interceptors are the methods which are used for each call request using axios. Interceptors helps to transform your request before calling api request and when it gets response from the api. It's just like working as middleware.

Configuration

You need to install npm package axios-interceptor-hook

Github Repo: (https://github.com/sheikhfahad67/axios-interceptor)

Run the command on your terminal.
npm install axios react-toastify axios-interceptor-hook

Installation

npm install axios react-toastify axios-interceptor-hook

axios and react-toastify are peer dependencies and needs to be installed explicitly

Example

import { ToastContainer } from 'react-toastify';
import { useAxiosInterceptor } from 'axios-interceptor-hook';
import { useEffect } from 'react';
import 'react-toastify/dist/ReactToastify.css';
function App() {
  const { data, isPending, apiHandler } = useAxiosInterceptor();
  const config = {
    method: 'get',
    url: '/todos',
    delay: 4000,
    successMessage: 'Todos data retrieve',
    errorMessage: 'Todos data fetch error',
  };
  const getTodosData = async () => {
    await apiHandler(config);
  };
  useEffect(() => {
    getTodosData();
  }, []);
  return (
    <div>
      <ToastContainer />
      {isPending && <p>Loading.......</p>}
      {data &&
        Object.keys(data).length > 0 &&
        data?.map((todo, index) => (
          <h6 key={index + 'testing'}>{todo.title}</h6>
        ))}
    </div>
  );
}
export default App;
