Meteor is a full-stack JavaScript platform that is used for developing modern web and mobile applications. Meteor has a set of features that are helpful in creating a responsive and reactive web or mobile application using JavaScript or different packages available in the framework. It is used to build connected-client reactive applications.
You can use Meteor.isClient to limit the code to only run on the client-side and Meteor.isServer to limit the code to only run on the server-side. Anything outside of .isClient and .isServer is gonna run on both.
Syntax:
if (Meteor.isClient) {
// The code is now running on the client...
}
if (Meteor.isServer) {
// The code is now running on the server....
}

Main.js
import { Template } from 'meteor/templating'; import './main.html'; Â Â Template.hello.onCreated(function helloOnCreated() { Â Â Â Â if (Meteor.isClient) { Â Â Â Â Â Â Â Â // The code is now running on the client... Â Â Â Â Â Â Â Â console.log("Meteor is running in the client?, ", Â Â Â Â Â Â Â Â Â Â Â Â Meteor.isClient); Â Â Â Â Â Â Â Â console.log("Meteor is running in the server?, ", Â Â Â Â Â Â Â Â Â Â Â Â Meteor.isServer); Â Â Â Â } Â Â Â Â Â Â if (Meteor.isServer) { Â Â Â Â Â Â Â Â // The code is now running on the server.... Â Â Â Â Â Â Â Â console.log("Meteor is running in the client?, ", Â Â Â Â Â Â Â Â Â Â Â Â Meteor.isClient); Â Â Â Â Â Â Â Â console.log("Meteor is running in the server?, ", Â Â Â Â Â Â Â Â Â Â Â Â Meteor.isServer); Â Â Â Â } }); |
