I'm new to Node.js from traditional languages and am still having issues with thinking asynchronously.
I got a function that makes a web service call. I need to call this function and retrieve the data from another class.
module.exports.getInfo = function() {
var req = http.request(options, function(res) {
var chunks = [];
res.on("data", function(chunk) {
chunks.push(chunk);
});
res.on("end", function() {
var body = Buffer.concat(chunks);
var results = JSON.parse(body.toString());
res(results);
});
});
req.end();
};
I'm calling this function through another file:
service = require ('service.js');
helper.getInfo();
//how do I get the 'results' variable here?
I am wondering how to get the results of the results
variable from the calling function.
I'm confused as to the series of nested functions. Is this the call stack as I understand it?
- GetInfo
- req
- res.on 'end'
How would I pass the data from the final function back through?
