In Meteor, it is very common to use the session variables.
// Save a value to x Session.set("x", "eureka"); // Get the value of x Session.get("x");
And sometimes we would like to use these session variables in the Handlebars template. This could be done by registering a helper in Handlebars.
client/js/main.js
Handlebars.registerHelper("variable_x", function(input){ return Session.get("x"); });
Then in your Handlebars template, you could get use the {{variable_x}} to recall the value stored in the session.
Done =)
