How to import from JSON file into Meteor

    // import data only when Products collection is empty

    if (Products.find().count() === 0) {
        console.log("Importing private/products.json to db")

        var data = JSON.parse(Assets.getText("products.json"));

        data.forEach(function (item, index, array) {





Meteor multi-tenancy patterns and package

Packages that can be used to create multi-tenant apps.

This is a ripped down version of what’s in my main.js file in the client:

if (!Session.get('tenantId')) {
  var hostnameArray = document.location.hostname.split('.'), subdomain;
  if (hostnameArray[1] === 'mydomainname' && hostnameArray[2] === 'com') {
    subdomain = hostnameArray[0];  
  if (subdomain) {'findTenantBySubdomain', subdomain, function(err, res) {
      var tenantId = res;
      if (tenantId) {
        Session.set('tenantId', tenantId); 

It’s not pretty, but it works. Note: subdomains are unique to tenants, so we can get the tenant _id value by finding the right document by subdomain:

  "findTenantBySubdomain" : function (subdomain) {
    check(subdomain, String);
    var tenant = Tenants.findOne({subdomain: subdomain});
    if (tenant) {
      return tenant._id;    


How to return a value with on client

 test: function() { if (this.isSimulation) { 
return 1; 
// Client wants this to be 1 
} else {
 return 2; // Server wants this to be 2 
} } });{
 'click button': function () {
 // Call the test method sync 
var clientResult = Meteor.apply('test', [], {returnStubValue: true});
 Session.set('result', clientResult); } });

Meteor multi-tenant architecture options

Looking into creating a multi-tenant app with Meteor?

Luckily you’re not alone and there are quite a few options available. We suggest you try reading the following links.

Also, a code snippet is included below which can give you some inspiration on how you want to approach this design pattern.

Meteor.publish("data", function() {
 var tenantId = Meteor.users.findOne({_id: this.userId}).tenantId;
 return MyCollection.find({tenantId: tenantId}, {fields: {tenantId: 0}});

Meteor.http. Get Proper Example


if (Meteor.is_server) {
		fetchFromService: function(userName) {
			var url = ""+userName+"&count=10";
			//synchronous GET
			var result = Meteor.http.get(url, {timeout:30000});
			if(result.statusCode==200) {
				var respJson = JSON.parse(result.content);
				console.log("response received.");
				return respJson;
			} else {
				console.log("Response issue: ", result.statusCode);
				var errorJson = JSON.parse(result.content);
				throw new Meteor.Error(result.statusCode, errorJson.error);
