React Weather App
React Weather App – Complete Beginner Project (2026)
Building a Weather App in React helps you understand how to work with APIs and display real-time data. This project is important for learning API integration, state management, and dynamic UI updates in real-world applications.
What is a Weather App
A Weather App allows users to search for a city and view current weather details like temperature, humidity, and conditions. It is a practical project using React and external APIs.
Features of Weather App
Search weather by city name
Display temperature and weather conditions
Show real-time data from API
Handle loading and error states
Project Structure

You can create separate components for search input and weather display.
Building Weather App Step-by-Step
Step 1: Setup State
function App() {
const [city, setCity] = useState(“”);
const [weather, setWeather] = useState(null);
Step 2: Fetch Weather Data
const response = await fetch(`https://api.openweathermap.org/data/2.5/weather?q=${city}&appid=YOUR_API_KEY`);
const data = await response.json();
setWeather(data);
};
Step 3: Handle Input and Button
type=“text”
value={city}
onChange={(e) => setCity(e.target.value)}
/>
<button onClick={getWeather}>Search</button>
Step 4: Display Weather Data
<div>
<h2>{weather.name}</h2>
<p>Temperature: {weather.main.temp}</p>
<p>Condition: {weather.weather[0].main}</p>
</div>
)}
How This Project Works
The app takes user input, sends a request to a weather API, and displays the response data in the UI. React updates the UI automatically when the state changes.
