Creating a comprehensive weather app involves multiple steps, including fetching data from a weather API, designing the user interface, and handling user interactions. Here, we'll provide a step-by-step guide with code blocks on how to build a simple weather app using HTML, CSS, and JavaScript.
Step 1: Set Up Your Environment
Before you start coding, make sure you have a code editor (e.g., Visual Studio Code) and a web browser installed on your computer.
Step 2: Design the HTML Structure
Create an HTML file (e.g., index.html) and define the basic structure of your weather app. You can use the following HTML code as a starting point:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Weather App</title>
<link rel="stylesheet" href="styles.css">
</head>
<body>
<div class="container">
<h1>Weather App</h1>
<input type="text" id="locationInput" placeholder="Enter a city">
<button id="searchButton">Search</button>
<div class="weather-info">
<h2 id="location"></h2>
<p id="temperature"></p>
<p id="description"></p>
</div>
</div>
<script src="script.js"></script>
</body>
</html>
Step 3: Style Your App
Create a CSS file (e.g., styles.css) to style your weather app. Here's a basic CSS code example:
body {
font-family: Arial, sans-serif;
background-color: #f0f0f0;
}
.container {
max-width: 400px;
margin: 0 auto;
text-align: center;
padding: 20px;
background-color: rgba(255, 255, 255, 0.5); /* Set the background color to be transparent */
border-radius: 10px;
box-shadow: 0 0 10px rgba(0, 0, 0, 0.3); /* Adjust the alpha value here for the box shadow transparency */
margin-top: 105px;
}
h1 {
font-size: 24px;
}
input[type="text"] {
width: 100%;
padding: 10px;
margin: 10px 0;
border: 1px solid #ccc;
border-radius: 5px;
}
button {
background-color: #007BFF;
color: #fff;
border: none;
padding: 10px 20px;
border-radius: 5px;
cursor: pointer;
}
.weather-info {
margin-top: 20px;
}
/* Add more styles as needed */
Step 4: Fetch Weather Data with JavaScript
Create a JavaScript file (e.g., script.js) to fetch weather data from a public weather API. We'll use the OpenWeatherMapAPI as an example. You'll need to sign up for a free API key from OpenWeatherMap.
const apiKey = 'YOUR_API_KEY';
const apiUrl = 'https://api.openweathermap.org/data/2.5/weather';
const locationInput = document.getElementById('locationInput');
const searchButton = document.getElementById('searchButton');
const locationElement = document.getElementById('location');
const temperatureElement = document.getElementById('temperature');
const descriptionElement = document.getElementById('description');
searchButton.addEventListener('click', () => {
const location = locationInput.value;
if (location) {
fetchWeather(location);
}
});
function fetchWeather(location) {
const url = `${apiUrl}?q=${location}&appid=${apiKey}&units=metric`;
fetch(url)
.then(response => response.json())
.then(data => {
locationElement.textContent = data.name;
temperatureElement.textContent = `${Math.round(data.main.temp)}°C`;
descriptionElement.textContent = data.weather[0].description;
})
.catch(error => {
console.error('Error fetching weather data:', error);
});
}
Step 5: Get Your API Key
Sign up for a free API key from OpenWeatherMap (or another weather API provider of your choice). Replace 'YOUR_API_KEY' in the JavaScript code with your actual API key.
Step 6: Test Your Weather App
Open your HTML file (index.html) in a web browser, enter a city name, and click the "Search" button. You should see the weather information displayed on the page.
I've added the background picture to the body element in the CSS style to beautify the weather app. Here's the updated code snippet with the background image included:
body {
font-family: Arial, sans-serif;
/* background-color: #f0f0f0; */
background-image: url('weather1.webp');
background-size: cover;
background-position: center;
background-repeat: no-repeat;
height: 100vh; /* Set the height to fill the viewport */
margin: 0; /* Remove default margin */
padding: 0;
}
Step 7: Deploy Your Weather App
To share your weather app with others, you can deploy it on a web hosting platform or use a service like GitHub Pages.
This is a basic example of a weather app. You can further enhance it by adding features like icons, more detailed weather information, and a five-day forecast. You can also improve the styling to make it more visually appealing.

Recently I've also done this weather app for Fun.
here it is you can also check out this one.
Live link
I've used Nextjs, Typescript, and Axios.
That sounds awesome! Weather apps are a great project to work on. I'd love to check out your version. Thanks for sharing the the live link . Could you share the GitHub repository link so I can take a look?
Sure here is the GitHub link: github.com/mahfuzurrahman01/weathe...
Amazing!
But a screenshot of the finished work, or a link to it would be great.
Thank you for the tip.I have now attached a screenshot of the finished work.
Awesome.
it doesnot showing anything

function fetchWeather(location) {

Great tutorial!
Like Dumebi, I would suggest including a screenshot or a codepen or similiar. You can even link to the code on Github/Gitlab/Gumroad, if you like!
Thank you for the feedback! I'm glad you found the tutorial helpful. I've attached some screenshots, and I'll be sure to add the GitHub link before the day is over. Stay tuned for the link, and feel free to reach out if you have any questions or need further assistance.
Nice, I will try to build it using react
Absolutely, using React can indeed lead to a more efficient and maintainable application. It provides a structured way to manage your app's state and UI components. I
Thank you so much for sharing, I am on the CSS leg of my learning journey but I'm excited to try this app out locally in the future. This was easy to follow thank you.
