Hello, i wonder if there’s any function like beforeSend in jquery $.ajax in Meteor, i want to implement a loading bar in my app and the loader component will be called every time Meteor.call triggered. Is there any solution could help me achieve this?
If you use meteor validated-method package to define your method, you can use mixins functions for hooks like pre, post , etc
Many third party packages provide many functions like that :

You could easily write your own monkey patch of Meteor.call so you can intercept it:
const _origMeteorCall = Meteor.call;
Meteor.call = function(name, ...args) {
// if it's a function, the last argument is the result callback,
// not a parameter to the remote method.
let callback;
if (args.length && typeof args[args.length - 1] === 'function') {
callback = args.pop();
}
console.log('calling...');
return _origMeteorCall.call(this, name, ...args, (err, res) => {
console.log('...done!');
callback && callback(err, res);
});
}
