javascript - JS turning dot seperated strings into hierarchical objects -


i'm trying convert list of strings hierarchical tree.

an example of json be:

{     "log_names": [         "one",         "one.one",         "one.two",         "one.three",         "one.three.one",         "two",         "three",         "three.one",         "three.one.three.two",         "four.one.some.more.stuff"     ] }

output
here, each level object, , each sublogger child of it's parent.
each logger object, might contain other objects subloggers. , moreover, three.two in three.one.three.two, because there isn't logger under three.one.three, considered single logger , not father logger. example four.one.some.more.stuff. because there no other loggers under four, single logger under same logic before

{     "one": {         "one": { },         "two": { },         "three": {             "one" : { }         }     },     "two": { },     "three": {         "one": {             "three.two" : { }         }     },     "four.one.some.more.stuff" : { } }

i'm having difficulty of implementing above logic (no other sons it's 1 logger , not father logger).

some advises or code examples nice

finally, algorithm looks existing key in object , takes next iteration, if not, generate new object, rest of array key.

var data = { "log_names": ["one", "one.one", "one.two", "one.three", "one.three.one", "two", "three", "three.one", "three.one.three.two", "four.one.some.more.stuff"] },      object = {};    data.log_names.foreach(function (a) {      var temp = object;        a.split('.').every(function (b, i, bb) {          if (b in temp) {              temp = temp[b];              return true;          }          temp[bb.slice(i).join('.')] = {};      });  });    console.log(object);

node.js - How do I prevent MongoDB replica set from querying the primary? -

read-operations-only: is there way have mongodb replica set, make mongodb instance on box connected to, mongodb gets queried? i have 3 ec2 instances behind aws load balancer. on each ec2 instance runs mongodb, part of replica set. i have express endpoints on nodejs , connect replica set follows mongodb.mongoclient.connect('mongodb://1.1.1.1,2.2.2.2,3.3.3.3.', function (err, db) { if (err) { complete('{}'); } else { i distribute load of queries evenly across 3 instances of mongodb replica set instead of default having queries routed ec2 instance primary mongodb defined, because destroys point of load balancer (which balance load of queries across 3 instances evenly). my understanding when connecting mongodb replica set, primary instance selected unless primary instance down, , therefore purpose of every secondary instance serve backup. in example people call hot,cold,cold. because there 2...
