Diff between meteor method and meteor pub/sub

this will help Meteor.publish is the pub part of pub-sub obviously. As data gets added or changed that is being published the server will automatically send it over to the client.
Meteor.call is request-response. You make a request, you get a response. Party's over. If data changes on the server that the method uses your client won't know about it until you make another call.

Meteor: Calling an asynchronous function inside a Meteor.method and returning the result


Tag : javascript , By : Andrew Bailey
Date : March 29 2020, 07:55 AM
this one helps. Andrew Mao is right. Meteor now has Meteor.wrapAsync() for this kind of situation.
Here's the simplest way to do a charge via stripe and also pass a callback function:
var stripe = StripeAPI("key");    
Meteor.methods({

    yourMethod: function(callArg) {

        var charge = Meteor.wrapAsync(stripe.charges.create, stripe.charges);
        charge({
            amount: amount,
            currency: "usd",
            //I passed the stripe token in callArg
            card: callArg.stripeToken,
        }, function(err, charge) {
            if (err && err.type === 'StripeCardError') {
              // The card has been declined
              throw new Meteor.Error("stripe-charge-error", err.message);
            }

            //Insert your 'on success' code here

        });
    }
});

Meteor How to export Meteor.publish and Meteor.method code from within a Meteor package


Tag : development , By : sgmichelsen

I wish this helpful for you Here is a package.js file , Make sure you use the livedata packages.
api.use( 'livedata', [ 'server' ] ) ;

Why will my subsequent Meteor method calls not wait for the first one to finish when I call Meteor.setTimeout()?


Tag : javascript , By : Icyflash

With these it helps The answer is that the setTimeout callback is executed outside the fiber in which the method is running. What that means is that the method actually finishes execution (returning undefined) before the setTimeout callback is ever invoked, and you get the behavior you observed.
To provide a better test (and for an example of using asynchronous functions in methods), try this:
if (Meteor.isServer) {
  var Future = Npm.require('fibers/future');

  Meteor.methods({
    test: function(){
      var fut = new Future();
      console.log("outside");
      Meteor.setTimeout(function(){
          console.log("inside");
          fut.return('done');
          return 'done';
      }, 2000);
      return fut.wait();
    }
  });
}

Meteor file upload with Meteor-CollectionFS giving error method not found


Tag : meteor , By : user176445

it should still fix some issue I am using following meteor package to upload the image , Make sure you also define this collection on the server side:
Uploads =new FS.Collection('uploads',{
    stores: [new FS.Store.FileSystem('uploads',{path:'~/projectUploads'})]
});

Meteor code must always run within a Fiber. Try wrapping callbacks that you pass to non-Meteor libraries with Meteor.bin

fixed the issue. Will look into that further You should do exactly what your error says: wrap your callback with Meteor.bindEnvironment.
ec2.describeImages(params, Meteor.bindEnvironment(function (err, data) {
  // ...
}));
