Implementation Reference
- index.js:26-47 (handler)Handler function that fetches current weather data for the given location using the wttr.in API and returns formatted weather information including temperature, humidity, wind speed, etc.
handler: async ({ location }) => { try { // Note: In a real implementation, you would use a proper API key // This is using a free weather API that doesn't require authentication const response = await axios.get(`https://wttr.in/${encodeURIComponent(location)}?format=j1`); const weatherData = response.data; return { location: location, current_condition: weatherData.current_condition[0], weather_description: weatherData.current_condition[0].weatherDesc[0].value, temperature_C: weatherData.current_condition[0].temp_C, temperature_F: weatherData.current_condition[0].temp_F, humidity: weatherData.current_condition[0].humidity, wind_speed: weatherData.current_condition[0].windspeedKmph }; } catch (error) { console.error('Error fetching weather:', error); throw new Error(`Failed to get weather for ${location}: ${error.message}`); } } - index.js:17-25 (schema)Input schema defining the required 'location' parameter as a string.
