title: useAPI description: Comprehensive guide on integrating and using the useAPI custom React hook within your project.

Overview

Welcome to the useAPI guide. This document provides all the necessary instructions to help you integrate and utilize the useAPI custom React hook within your application. This hook is designed to simplify sending API requests and handling responses, including managing loading states and errors.

Prerequisites

Before proceeding, ensure you have the following:

  • Node.js installed
  • Basic knowledge of the command-line interface (CLI)
  • A code editor (e.g., VSCode)
  • A working React project where you want to implement the useAPI hook

Setup Instructions

Step 1: Create the useAPI Hook

Create a useAPI.js file within your project's hooks directory. This file will contain the custom hook implementation.

// src/hooks/useAPI.js
import { useState } from 'react';

const useAPI = () => {
  const [isLoading, setIsLoading] = useState(false);
  const [error, setError] = useState(null);

  const getLocationFromIp = async () => {
    const url = 'https://ipinfo.io/json?token=your_token_here'; // Replace 'your_token_here' with your actual token
    try {
      const response = await fetch(url);
      const data = await response.json();
      if (data.city && data.country) {
        return `${data.city}, ${data.country}`;
      } else {
        throw new Error('City or country information is missing');
      }
    } catch (err) {
      console.error('Error fetching location from IP:', err);
      return '';
    }
  };

  const getUserLocation = () => new Promise(async (resolve, reject) => {
    if (!navigator.geolocation) {
      const cityCountry = await getLocationFromIp();
      resolve({ cityName: cityCountry });
    } else {
      navigator.geolocation.getCurrentPosition(
        async () => {
          const cityCountry = await getLocationFromIp();
          resolve({ cityName: cityCountry });
        },
        async () => {
          const cityCountry = await getLocationFromIp();
          resolve({ cityName: cityCountry });
        },
        {
          maximumAge: 60000,
          timeout: 15000,
          enableHighAccuracy: true
        }
      );
    }
  });

  const postData = async (url, data, apiKey) => {
    setIsLoading(true);
    setError(null);
    try {
      const locationInfo = await getUserLocation();
      console.log('Location:', locationInfo);
      const updatedData = { ...data, location: locationInfo.cityName };

      console.log('Sending data with location:', updatedData);

      const response = await fetch(url, {
        method: 'POST',
        headers: {
          'Content-Type': 'application/json',
          'x-api-key': apiKey,
        },
        body: JSON.stringify(updatedData),
      });

      if (!response.ok) {
        throw new Error('Something went wrong!');
      }

      const responseData = await response.json();
      setIsLoading(false);
      return responseData;
    } catch (err) {
      setError(err.message);
      setIsLoading(false);
    }
  };

  return { postData, isLoading, error };
};

export default useAPI;

Step 2: Import and Use the useAPI Hook

After setting up the useAPI hook, you can integrate it within your React components to manage API requests efficiently.

Example:

import React from 'react';
import useAPI from 'src/hooks/useAPI';

function MyComponent() {
  const { postData, isLoading, error } = useAPI();

  const handleSubmit = async (e) => {
    e.preventDefault();
    const formData = {
      // Your form data here
    };
    const response = await postData('http://your-api-endpoint', formData, 'your-api-key');

    // Process the response...
    console.log(response);
  };

  return (
    <div>
      <form onSubmit={handleSubmit}>
        {/* Your form elements here */}
        <button type="submit">Submit</button>
      </form>
      {isLoading && <p>Loading...</p>}
      {error && <p>Error: {error}</p>}
    </div>
  );
}

export default MyComponent;

Step 3: Handling UI States

You can use the isLoading and error states provided by the useAPI hook to enhance your UI. For example, you can display a loading message while the API request is in progress or an error message if the request fails.

if (isLoading) return <p>Loading...</p>;
if (error) return <p>Error: {error}</p>;
