Meteor Remote MongoDB

I don’t like to use big repeating command and I was searching for a solution where I will be setting a variable embedded with something so every time I start my meteor app; the MONGO_URL will set to environment automatically. So this what I did:

In the package.json file I replaced the start parameter as below:

"scripts": {
    "start": "MONGO_URL=mongodb://username:password@host_url:portnumber/dbname meteor run"



Fix: Error: Cannot find module ‘@babel/runtime/helpers/builtin/objectSpread’

Another common error:

Error: Cannot find module ‘@babel/runtime/helpers/builtin/interopRequireDefault’

How to fix:

This has been traced in the forums as an incompatibility with the latest version of @babel/runtime. Change the corresponding line in the package.json file

  "dependencies": {
    "@babel/runtime": "7.0.0-beta.55",

and then do

meteor npm install

How to import from JSON file into Meteor

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;
