Execute function for every helper and events - node.js

Question

I'm trying to build an automatic error reporting system for my meteor app but there is one little thing I'm not able to do right now. I would like to know if it is possible to create some sort of wrapper that would execute each time a helper or an event is called, for any template.
I've searched in blaze.js to see how they handle it and possibly edit it but I guess altering this file is not the way to go.
I found nothing about that, and at this point, I'm not sure it is even possible.
EDIT: I found some sort of a solution but it's far from perfect.
I've created a globalHelper :
Template.registerHelper('checkError', (tmplName, helperName, ...args) => {
try {
return Template[tmplName].__helpers.get(helperName).apply(this, args);
} catch(error) {
let trace = error.stack.split('\n').map(function (line) { return line.trim(); })
let obj = {
text: "" + error,
date: parseInt(Date.now() / 1000),
function: trace[0].split('#')[0],
template: tmpl,
trace: trace.slice(0, trace.length - 1)
}
Meteor.call("logNewCrash", obj, function(err, res) {
if (!err) {
Bert.alert("Une erreur est survenue et à été communiquée à un administrateur. Elle sera traitée dans les plus brefs délais.", "danger");
}
})
}
});
It works as expected but I need to call this helper instead of the original ones, for exemple :
<template name=templateName1>
{{#if checkError 'templateName1' 'helperName1' arg1 arg2}}
<!--do something-->
{{/if}}
</template>
with the following helper :
helperName1(arg1, arg2) {
if (arg1 == arg2)
return true;
return false;
}
EDIT 2 :
So I dropped my previous work to create a meteor package.
I successfully overrode Blaze._wrapCatchingExceptions like so :
Blaze._wrapCatchingExceptions = function (f, where) {
if (typeof f !== 'function')
return f;
return function () {
try {
return f.apply(this, arguments);
} catch (error) {
let trace = error.stack.split('\n').map(function (line) { return line.trim(); })
let obj = {
text: "" + error,
date: parseInt(Date.now() / 1000),
function: trace[0].split('#')[0],
template: Template.instance().view.name.split('.')[0],
trace: trace.slice(0, trace.length -1)
}
Meteor.call(configuration.method, obj, function(err, res) {
if (!err) {
Bert.alert(res.msg, "danger");
}
});
Blaze._reportException(error, 'Exception in ' + where + ':');
}
};
};
However, some errors aren't handled by Blaze but by Tracker. This is where it's getting frustrating, I can't get my Tracker override to work.
I tried to override Tracker._runFlush and _throwOrLogbut either I got a Maximum stack size exceeded or my function is just not called at all.
I probably was doing it wrong.
What am I missing ?
Thanks
