Just repeating (a simplified verion of) the example given here
import { Meteor } from 'meteor/meteor'
if (Meteor.isServer) Meteor.methods({ 'normal' : () => 1 })
if (Meteor.isClient)
{
const call = method_name => new Promise ((resolve, reject) => {
Meteor.call(method_name, (e, r) => resolve(r))
})
const f = async () => {
const r = await call ('normal')
console.log (r)
}
f ()
}
It prints 1
