Monkey-patches to meteor/mongo.

Helpful for working with indexes and transitioning away from Fibers.

Update, November 2022:

Meteor 2.8 updated the core meteor/mongo package to add *Async versions of Mongo methods by default. See: meteor/meteor#11605

Since the new core methods have identical signatures to the ones previously provided by this package, the 3.x release of this package has been updated to remove the overlapping methods.

Now, the package only includes helpers related to working with indexes or aggregation.

Description

This package extends the Collection prototype from meteor/mongo with a few handy helpers related to indexes and aggregation. It's intended for use only with projects built with Meteor.

API

Collection Prototype

Collection.updateManyAsync(selector, modifier, ?options);

Same as Collection.updateAsync; passes { multi: true } in addition to the passed options.

Collection.getIndexes();

Returns a Promise that is resolved with an array of indexes for this collection. For example, you might see this for a users collection with only an index on ID:

[{ v: 2, key: { _id: 1 }, name: '_id_', ns: 'meteor.users' }]

Collection.ensureIndex(selector, options);

Ensures an index exists. Similar to the built-in createIndex, but handles the case where the index already exists with different options by removing and re-adding the index with the new options. To ensure your database has the same indexes across different environments, you might want to add ensureIndex calls to Meteor.startup.

Collection.ensureNoIndex(selector);

The reverse of ensureIndex. You might want to call this in Meteor.startup to make sure an index has been removed in all of your deployed environments.

Collection.aggregate(pipeline, ?options);

Exposes the aggregate method. This removes the need to use rawCollection() every time you want to aggregate.

Install

npm install @codesignal/meteor-protomongo

After the package is installed, add the following few lines in a file that's going to be loaded on startup:

import { Mongo } from 'meteor/mongo';
import ProtoMongo from '@codesignal/meteor-protomongo';

ProtoMongo.extendCollection(Mongo);
