JavaScript Node.js Basics 2017 Create a Command Line Weather Application Retrieving Data - Solution

parseInt will omit 0 at the beginning of a zip code

This is related to openweather API solution on the teacher's notes Hi guys, I just wanted to let you know, that if your query has a zip code for example 01581,

const zipCode = parseInt(query);
if (!isNaN(zipCode)) {
      parameters.zip = zipCode + ',us';
    } else {
      parameters.q = query + ',us';

    const url = `https://api.openweathermap.org/data/2.5/weather?${querystring.stringify(parameters)}`;

The parseInt will ignore the zero and will return 1581, being an invalid zip code in United States, (I think it has to be 5 digits), so, the url will have : ?zip=1581%2cus instead of ?zip=01581%2cus The API response will be statusCode 404 So make sure to validate that you have a 5 digits zip code before adding it to the url.

Rather than converting it to an int, it's easier to just check it with regex.

Great solution, Zimri. I came up with an alternative that also seems to work: if (parseInt(query)) { parameters.zip = query; } else { parameters.q = query + ',us'; }
