javascript - Node Call Export on Callback -


i'm banging head not learning basics , jumping in.

i'm building api returns ssl certificate status of domain. it's working fine on console.log json output empty, because exports executed before https request ends.

how incorporate exports in response.on(end) function? lot!

function getssl(domain) {        var options = {          host: 'www.'+domain+'.com',          method: 'get',          path: '/'      };        var isauth = false;        callback = function(response) {            response.on('data', function () {              isauth = response.socket.authorized;          });            response.on('end', function () {              console.log(isauth);          });        }             var req = https.request(options, callback).end();  }    exports.findbydomain = function (req, response) {      var id = req.params.id;      sslcheck = getssl(id);      response.send(sslcheck);  };

yes, response.send(sslcheck); gets executed before getssl(id); has chance finish. need send in callback can executed after getssl(id); finishes:

function getssl(domain, callback) {      var options = {         host: 'www.'+domain+'.com',         method: 'get',         path: '/'     };      var isauth = false;      var httpcallback = function(response) {          response.on('data', function () {             isauth = response.socket.authorized;         });          response.on('end', function () {             console.log(isauth);             callback(isauth);         });      }    var req = https.request(options, httpcallback).end(); }  exports.findbydomain = function (req, response) {     var id = req.params.id;     getssl(id, function(sslcheck) {         response.send(sslcheck);     }); };

i have model ( article ) field (the name type ) of type enum('source', 'translated') , return 1 article ordered type field. source articles should returned before translated articles. like: article.findone(order: [ { type: [ 'source', 'translated' ] } ]); unfortunately there appears no built-in solution sorting enums. instead have sort by case , couldn't find documentation on how sequelize. what conventional approach here? sorting case hard in sequelize, sort field (the second answer in linked post) should possible: order: sequelize.fn('field', sequelize.col('type'), 'source', 'translated') it's supported mysql far know though
