Creating a weather dashboard is a great way to practice working with APIs and building user interfaces. In this tutorial, we'll build a simple weather dashboard using JavaScript and a Mock Weather API. This will allow us to fetch and display weather data without needing access to a live weather API. The Mock API will simulate real-world scenarios, making it an excellent tool for development and testing.
We will be using Dummy Weather API for this project.
Prerequisites
To follow along with this tutorial, you'll need:
- Basic knowledge of HTML, CSS, and JavaScript.
- A code editor (like VSCode).
- A web browser.
Setting Up the Project
First, let's set up a simple HTML page that will serve as our weather dashboard.
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Weather Dashboard</title>
<style>
body {
font-family: Arial, sans-serif;
display: flex;
flex-direction: column;
align-items: center;
padding: 20px;
}
.weather {
border: 1px solid #ccc;
padding: 20px;
border-radius: 5px;
margin-top: 20px;
width: 300px;
text-align: center;
}
</style>
</head>
<body>
<h1>Weather Dashboard</h1>
<input type="text" id="city" placeholder="Enter city name">
<button id="getWeather">Get Weather</button>
<div id="weatherContainer"></div>
<script src="app.js"></script>
</body>
</html>
Writing JavaScript to Fetch Weather Data
Next, we'll write JavaScript to fetch weather data from the Mock API and display it on our dashboard.
Create a file named app.js and add the following code:
document.getElementById('getWeather').addEventListener('click', getWeather);
async function getWeather() {
const city = document.getElementById('city').value;
if (!city) {
alert('Please enter a city name');
return;
}
try {
const response = await fetch(`https://api.mockx.net/weather/search?q=${city}`);
const data = await response.json();
displayWeather(data.weathers);
} catch (error) {
console.error('Error fetching weather data:', error);
}
}
function displayWeather(weathers) {
const weatherContainer = document.getElementById('weatherContainer');
weatherContainer.innerHTML = ''; // Clear previous weather data
if (weathers.length === 0) {
weatherContainer.innerHTML = '<p>No weather data found for the entered city.</p>';
return;
}
weathers.forEach(weather => {
const weatherDiv = document.createElement('div');
weatherDiv.className = 'weather';
weatherDiv.innerHTML = `
<h2>${weather.location.city}, ${weather.location.country}</h2>
<p>Temperature: ${weather.current_weather.temperature}°C</p>
<p>Condition: ${weather.current_weather.weather_condition}</p>
<p>Humidity: ${weather.current_weather.humidity}%</p>
<p>Wind Speed: ${weather.current_weather.wind_speed} km/h</p>
<p>Air Quality: ${weather.air_quality.category} (${weather.air_quality.index})</p>
`;
weatherContainer.appendChild(weatherDiv);
});
}
Explanation
HTML Structure: We have a simple HTML structure with an input field for the city name, a button to trigger the weather fetch, and a container to display the weather data.
Fetching Weather Data: When the button is clicked, the getWeather function is called. This function fetches weather data from the Mock API based on the entered city name.
Displaying Weather Data: The displayWeather function takes the fetched weather data and dynamically creates HTML elements to display the information.
Running the Application
To run the application, simply open the index.html file in your web browser. Enter a city name and click the "Get Weather" button to see the weather data for that city.
Conclusion
Using Mock APIs is a fantastic way to practice working with real-world data without needing access to live servers. In this tutorial, we built a simple weather dashboard using JavaScript and a Mock Weather API. This approach allows you to test and develop your applications in a controlled environment.
