How to access API data globally?

let dataset = [];
    .then(response => response.json())
    .then(data => {
      // const coords = [{lat : data[0].lat ,
      // lon : data[0].lon
      // }];
      let lat = data[0].lat;
      let lon = data[0].lon;
      const link = "" + lat + "&lon=" + lon + "&appid=" + appid + "&units=metric";
      return fetch(link);
    .then(responce => responce.json())
    .then(data => {
      dataset = JSON.stringify(data["data"]);
  });"/searchloc", function(req,res){
  let iconurl = ""+[0].icon+"@2x.png"
  res.render("searchloc",{icon:iconurl });

When I run this code I get error TypeError: Cannot read properties of undefined (reading 'weather'), So how can I access weather data in searchloc post request?

[edit: as long as your version of Node is 14 or higher, ie it’s not an old version] Add the keyword await in front of the word fetch

Edit: also didn’t see you were making a query in the query. I would flatten out the logic here, something like:

const coordData = await fetch(coordinatelink).json();

const [lat, long] = [coordData[0].lat, coordData[0].lat];
const link = `${lat}&lon=${lon}&appid=${appid}&units=metric`;
const { data } = await fetch(link).json();
const dataset = JSON.stringify(data);

It says

   await fetch(coordinatelink)

SyntaxError: await is only valid in async functions and the top level bodies of modules

Ah, sorry I haven’t used CJS modules in Node for a fair while, forgot it required actual JS modules (import foo from "./bar" rather than const foo = require("./bar")),

So with what you are using, to make what I posted work, simplest way is to wrap in a self-executing async function, eg:

(async () = {
  // Logic here

Or you can use a set of async functions.

Otherwise you need to put the call in another then, otherwise it will try to execute before the promise has resolved – this is how JS works
