Javascript Programming Tutorials, Guides & Best Practices

Create a new file named weather.js and add the following code:

const axios = require('axios');

// Replace with your own OpenWeatherMap API key
const apiKey = 'YOUR_API_KEY';

// Function to get the weather for a city
async function getWeather(city) {
    try {
        const response = await axios.get(`https://api.openweathermap.org/data/2.5/weather`, {
            params: {
                q: city,
                appid: apiKey,
                units: 'metric'
            }
        });

        const weather = response.data;
        const temperature = weather.main.temp;
        const description = weather.weather[0].description;
        const humidity = weather.main.humidity;

        console.log(`Weather in ${city}:`);
        console.log(`Temperature: ${temperature}°C`);
        console.log(`Description: ${description}`);
        console.log(`Humidity: ${humidity}%`);
    } catch (error) {
        console.error(`Could not retrieve weather data: ${error}`);
    }
}

// Prompt the user for a city name
const readline = require('readline').createInterface({
    input: process.stdin,
    output: process.stdout
});

readline.question('Enter the city name: ', city => {
    getWeather(city);
    readline.close();
});
