Leveraging Mongo aggregation in Meteor applications

I have integrated the $lookup operator from MongoDB into my Meteor collection using the tunguska:reactive-aggregate package obtained from AtmosphereJs (). Below is an example of how I implemented it following the package documentation:

import { ReactiveAggregate } from 'meteor/tunguska:reactive-aggregate';

Meteor.publish("orders", function () {
  ReactiveAggregate(this, OrdersCollection, [{
    $lookup: {
      from: "customers",
      localField: "customer_id",
      foreignField: "wooCommerce_id",
      as: "customerInfo"
    }
  }]);
})

The integration works seamlessly, and I successfully retrieve the customer's information in the customerInfo field of the collection. However, when TypeScript compiler comes into play, it raises an error as follows:

error TS2307: Cannot find module "meteor/tunguska:reactive-aggregate"

This issue seems to be related to including the package correctly within the project. Perhaps there is a need to add the package to the list of "detected" ones similar to importing other packages like meteor/check. Despite the app functioning as intended, having errors flagged in the IDE can be bothersome...

Your suggestions or solutions will be greatly appreciated!

Answer №1

Upon examining the directory structure of the Meteor project, it appears that I have gained a better understanding of what is happening:

  • I have discovered that Meteor packages are not located in the node_modules directory, but rather in
    .meteor/local/build/programs/server/packages
    . It seems that Meteor bundles these packages during the compilation process, allowing them to be imported and used within the application.
import { ReactiveAggregate } from 'meteor/tunguska:reactive-aggregate';

Meteor.publish("orders", function () {
  ReactiveAggregate(this, OrdersCollection, [{
     ...
  }]);
});

However, there is one issue – my IDE is indicating that it cannot locate the module. To resolve this, I will need to create a typings file since none currently exist. I plan on doing this when I have some spare time available.

Cheers!
