https://morizyun.github.io/javascript/node-js-npm-library-node-fetch.html node.js でfetchをつかえるようにするimport fetch from 'node-fetch';
var APIKEY = '518c255d266e82b0f903e3ba905c437c';
var location = "Tokyo,jp";
fetch( `http://api.openweathermap.org/data/2.5/weather?q=${location}&appid=${APIKEY}`)
.then(res => res.json())
.then(json => console.log(json));
をindex.mjs(jsでなく）としてnode.mjsでOk 518c255d266e82b0f903e3ba905c437c my weather api
