Weather

In the /Chapter08/weather/ folder of the repository, you will find weather.js. This is a simple Node.js function that queries the Yahoo weather API to return the current weather for a given location:

'use strict';const rp = require('request-promise-native');module.exports = async function (context) {    const stringBody = JSON.stringify(context.request.body);    const body = JSON.parse(stringBody);    const location = body.location;    if (!location) {        return {            status: 400,            body: {                text: 'You must provide a location.'            }        };    }    try {        const response = await rp(`https://query.yahooapis.com/v1/public/yql?q=select item.condition from weather.forecast where woeid in (select woeid from geo.places(1) where text="${location}") and u="c"&format=json`);
