Data from LDAP query in variable LdapJS

Question

I'm trying to get the data from LDAP and I'm getting it successfully but it's not written into variable so then after the code is executed I can make some checks on the data.

var server = LdapJS.createClient({
    url: LdapConf.server.url,
    tlsOptions: LdapConf.server.tlsOptions
});
server.bind(LdapConf.server.bindDN, LdapConf.server.bindCredentials, function(err) {
    if (err) {
        return done(err);
    }
});
var SearchOtps = {
    filter: '(uid=' + username + ')',
    scope: 'one',
};


var UserSearch = server.search(LdapConf.server.searchBase, SearchOtps, function(err, res) {
    res.on('searchEntry', function(entry) {
        console.log('entry: ' + JSON.stringify(entry.object));
        return (JSON.stringify(entry.object));
    });
    res.on('searchReference', function(referral) {
        //console.log('referral: ' + referral.uris.join());
    });
    res.on('error', function(err) {
      //console.error('error: ' + err.message);
    });
    res.on('end', function(result) {
      //console.log('status: ' + result.status);
    });
});

console.log(UserSearch);

I just do not know how to stop further code execution while it's waiting for the return of the LDAP search.

You could do a function that returns it in promise.

function UserSearch(server,LdapConf, SearchOtps) {
  return new Promise(function(resolve,reject) {

    server.search(LdapConf.server.searchBase, SearchOtps, function(err, res) {
        res.on('searchEntry', function(entry) {
            console.log('entry: ' + JSON.stringify(entry.object));
            resolve(JSON.stringify(entry.object)));
        });
        res.on('searchReference', function(referral) {
            //console.log('referral: ' + referral.uris.join());
        });
        res.on('error', function(err) {
          reject()
        });
        res.on('end', function(result) {
          //console.log('status: ' + result.status);
        });
    });
  }
 }
 
 UserSearch(server,LdapConf, SearchOtps)
 .then(function(res) {
   console.log(res)
 })

I've added the function but it seems that the only thing I'm getting is `[Function: getData]`. I did `var UserSearch = function getData() {` and your code. – hplodur May 02 '18 at 11:16
Corrected it with `var UserSearch = getData();` and I'm getting now `Promise { }` – hplodur May 02 '18 at 11:19
It is a promise so you need to call then to get the data, like in the example above :) If you are not familiar with promises they are simply explained [here](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Promise) – anttud May 02 '18 at 11:23
