If you want to limit the code to run only on the server or the client side, you can use the following code −

meteorApp.js

if (Meteor.isClient) {
   // Code running on client...
}

if (Meteor.isServer) {
   // Code running on server...
}

You can limit the code to run only when the app is using Cordova bundling.

if (Meteor.isCordova) {
   // Code running on Cordova...
}

Some plugins need to wait until the server and DOM are ready. You can use the following code to wait until everything begins.

Meteor.startup(function () {
   // Code running after platform is ready...
});
