Return a variable and pass it to view
I have a sails.js web application and I have a crawling function that get the title of a website then I want to return that value to the view.
I tried to assign the function to a variable and return it but always it says undefined.
const Crawler = require("crawler");
let c = new Crawler({
maxConnections : 10,
callback : function (error, res, done) {
if(error){
console.log(error);
}else{
let $ = res.$;
let title = $("title").text();
}
return title
done();
}
});
module.exports = {
testapi: function (req, res) {
title = c.queue('http://www.agounichams.ml');
sails.log(title);
return res.send(c.title);
}
}
javascript sails.js

Shouldn't it be
title = await c.queue('http://www.agounichams.ml');
?
And declaring title just as that, without a const, let, etc makes it global if that is intended.
