Weather Application using ReactJS | react mini project

#javascript #beginners #programming #webdev

Using the ReactJS Framework, In this React js weather application tutorial we will create an interactive weather application. The user will be able to access real-time weather information for the city they have searched for through the built application by consuming the api from openweathermap .Also you can find the React js weather application github code.

Live Demo.

Asset Link.

Let's take a peek at our finished product in an interactive manner | React js weather application example:

Technologies Used/Pre-requisites:

ReactJS
React js.
CSS.
JSX.
Function Components in React.

Method:

The ReactJS Framework is used in the produced code to display the interactive Weather Application. Users of the programme can access real-time information about a variety of cities. We are retrieving the weather information for the city that the user has looked for with the aid of API. The application is fully responsive, and it responds quickly in terms of output. The user interface of the app is likewise user-friendly.

Project Structure:

Steps to create React Application And Installing Module
Step 1: Create a React application using the following command:
npx create-react-app projectname

then jump to the directory
cd projectname
Step 2: To run the application:
npm start

Example: Insert the below code in the respective files.

App.js: All the logic of this application for weather application i have write in the App.js file
Index.css: You guys can also write the styling part in the index.css or app.css but in this application case we will write all the css code in the index.css file

App.js

import React, { useState } from "react";
import { useEffect } from "react";

function App() {
  const [city, setCity] = useState("Delhi");
  const [weatherData, setWeatherData] = useState(null);
  const [error, setError] = useState(null);

  const currentDate = new Date();

  const months = [
    "January", "February", "March", "April", "May", "June",
    "July", "August", "September", "October", "November", "December"
  ];

  const month = months[currentDate.getMonth()];
  const day = currentDate.getDate();
  const year = currentDate.getFullYear();

  const formattedDate = `${month} ${day}, ${year}`;

  const API_KEY = "bcda10ba323e88e96cb486015a104d1d"; // Replace 'YOUR_API_KEY' with your actual API key from OpenWeatherMap

  const fetchWeatherData = async () => {
    try {
      const response = await fetch(
        `https://api.openweathermap.org/data/2.5/weather?q=${city}&appid=${API_KEY}&units=metric`
      );
      const data = await response.json();
      console.log(data)
      // if (response.ok) {
      setWeatherData(data);
      // setError(null);
      // } else {
      //   setError(data.message);
      //   setWeatherData(null);
      // }
    } catch (error) {
      console.error("Error fetching weather data:", error);
      // setError("Error fetching weather data. Please try again later.");
      // setWeatherData(null);
    }
  };

  useEffect(()=>{

  fetchWeatherData();

  },[])

  const handleInputChange = (event) => {
    setCity(event.target.value);
  };

  const handleSubmit = (event) => {
    event.preventDefault();
    fetchWeatherData();
  };

  const getWeatherIconUrl = (main) => {
    switch (main) {

      case "Haze":
        return "/sun.png"; // Path to your haze weather icon
      // Add more cases for other weather conditions as needed

Conclusion:

We have successfully build this weather application using react js and we have used many technologies in it . To build this react js weather application . i hope you will love this tutorial get so many knowledge from this video. I’m hoping you’ll create this application effectively and get a lot of knowledge from it. We designed this project as a beginner project, but in the future days we will cover more advanced projects as well.
