Meteor JS - 客户端集合似乎是空的(Meteor JS - Client Collection seems to be empty)

 自从我使用Meteor或涉足UI世界以来已经很长时间了，所以如果这是一个糟糕的问题，请原谅我。 
 
 API / main.js： 
 
export const Nodes = new Meteor.Collection("nodes");
export const Links = new Meteor.Collection("links");
 
 服务器/ main.js 
 
import { Links, Nodes } from '../api/main.js';

Meteor.startup(() => {
  // code to run on server at startup
}

Meteor.methods({
  traverseDocument: function traverseDocument(documentKey) {
    // ... do stuff ...
    Links.insert( data.links );
    Nodes.insert( data.nodes );
    return data;
  }
}
 
 客户机/ main.js 
 
import { Links, Nodes } from '../api/main.js';
import './main.html';

Meteor.startup(function () {
  // Fetch data via a call
  Meteor.call("traverseDocument", 'NTD000000228506', function (error, results) {});
});

Template.viz.rendered = function () {
  console.log(Nodes.find());                 // <-- LocalConnection.Cursor()
  console.log(Nodes.find().fetch());         // <-- This is empty []
  console.log(Nodes._collection._docs._map); // <-- This returns Object{}
}
 
 我尝试过：1。发布/订阅2.我尝试了一个辅助函数3.我已将Meteor.Call（）移动到客户端启动函数中 
 
 所以这现在似乎更接近工作了。 
 
 原始问题现在改为 - 为什么find（）。fetch（）返回一个空数组？ 
 
 也许我应该发一个新问题并将其标记为固定？ 

Its been a long time since I used Meteor or dabbled in the UI world for that matter, so forgive me if this is poor question.
 
api/main.js:
 
export const Nodes = new Meteor.Collection("nodes");
export const Links = new Meteor.Collection("links");
 
server/main.js
 
import { Links, Nodes } from '../api/main.js';

Meteor.startup(() => {
  // code to run on server at startup
}

Meteor.methods({
  traverseDocument: function traverseDocument(documentKey) {
    // ... do stuff ...
    Links.insert( data.links );
    Nodes.insert( data.nodes );
    return data;
  }
}
 
client/main.js
 
import { Links, Nodes } from '../api/main.js';
import './main.html';

Meteor.startup(function () {
  // Fetch data via a call
  Meteor.call("traverseDocument", 'NTD000000228506', function (error, results) {});
});

Template.viz.rendered = function () {
  console.log(Nodes.find());                 // <-- LocalConnection.Cursor()
  console.log(Nodes.find().fetch());         // <-- This is empty []
  console.log(Nodes._collection._docs._map); // <-- This returns Object{}
}
 
I've tried: 1. Publish/Subscribe 2. I tried a helper function 3. I Have moved the Meteor.Call() into the client startup function
 
So this now seems to be closer to working.
 
The original question changes now to - Why does the find().fetch() return an empty array ?
 
Maybe I should post a new question and mark this one as fixed ?
