How to return callback node.js?

Question

 var iwconfig = require("wireless-tools/iwconfig"); let api = {}; api.getStatusWifi = function () { iwconfig.status(function (err, status) { console.log(status); }); // return status ??????????? }; module.exports = api;

how can I pass the "status callback" return to the "getStatusWifi"?

Answer 1

You need to put the "api.getStatusWifi =" part inside the function where the status variable is available.

var iwconfig = require("wireless-tools/iwconfig");
let api = {};

 iwconfig.status(function (err, status) {
    api.getStatusWifi = function () {
     return status;
    };
 });
  
module.exports = api;
