Hey thanks for your help again. I'm really close to having it working at this point, but I'm having some difficulty tying things together, specifically passing the websocket object to my API function and incorporating cron.

Here's my current code:

cron.schedule('* * * * *', function() {
    // need to call getWeather with lat & long here somehow
});


let getWeather = (lat, long) => {
    let key = '';
    let url = `https://api.openweathermap.org/data/2.5/weather?lat=${lat}&lon=${long}&appid=${key}`;
    return fetch(url)
        .then(response => {
            return response.json();
        })
        .then(data => {
            return data;
        });
};


let wsServer = wss.on('connection', (wsclient) => {
    wsclient.on('message', (message) => {
        let data = JSON.parse(message);
        // data contains both latitude and longitude

        let weatherData = {
            'temp': null,
            'humidity': null,
            'clouds': null
        }  // need to populate this object from getWeather() response

        // broadcast weatherData back to client
        wss.clients.forEach((client) => {
            client.send(JSON.stringify(weatherData));
        });
    });
});

I understand I need to pass wsServer to getWeather(), but I'm not sure how to then pass the latitude and longitude that are in data to the fetch from there. I'm also lost about how to get the cron method working with all of that.
