Hopefully this is a newbie question. I have the following code that I am trying to convert to using meteor.wrapAsync. I am getting a "Exception while invoking method 'emailSend' ReferenceError: syncfunc is not defined" exception. What am i missing?
Stack Trace:

email.js:
Meteor.methods(
{
emailSend(fromAddress, subject, emailText)
{
if (Meteor.isServer)
{
const { Email } = require('../server/email.js');
var syncFunc = Meteor.wrapAsync(Email.send);
var sendEmailReturn=syncfunc(fromAddress, subject, emailText);
return sendEmailReturn;
**//if I comment out the above three lines and uncomment the line below then the application works fine.**
//return Email.send(fromAddress, subject, emailText);
}
},
})
You don't need to use external callback to sync methods as Meteor supports "async" and "awaits" by default. Below is an example of using 'await' method.
Meteor.methods({
async emailSend(fromAddress, subject, emailText) {
const { Email } = require('../server/email.js');
var sendEmailReturn = await Email.send(fromAddress, subject, emailText);
}
});
I believe Meteor.defer
is more suited to what you're trying to achieve here.
Example:
Meteor.methods({
'action_plus_email': function () {
// do something
Meteor.defer(() => {
Email.send(...)
})
return 'hello there, user';
}
})

And if you're are going to be sending many emails, please take a look at mail-time. It can be of great help.
