meteor-mongodb-collections v0.0.14

meteor-mongodb-collections

This module acts as a singleton that you can use with async/await in a Meteor-like "synchronous" fashion to interact with MongoDB collections.

Intended usage is for CLI or "serverless" (Lambda/GCF) apps that need to interact with Meteor-based apps to generally make life easier while developing. There are no projections, all the finds are automatically returned as arrays.

I use this in my own internal projects so it's pretty simple, but feel free to contribute.

Usage:

Mongo.setDb(db);

Set the DB in the singleton.

Mongo.setClient(client);

Set the Mongo client in the singleton.

Mongo.getDb();

Get the DB from the singleton.

Mongo.getClient();

Get the Mongo client from the singleton.

new Mongo.Collection('collection_name');

Create a new collection

Example:

In your entry point:

index.js

const Mongo = require('meteor-mongodb-collections'); // This creates the singleton.
const MongoClient = require('mongodb').MongoClient;
const doStuff = require('./doStuff.js');

async function connect() {

  try {

    const client = await MongoClient.connect(config.MONGO_URL);
    const db = client.db(client.s.options.dbName);

    Mongo.setDb(db);         // Set the db in the singleton.
    Mongo.setClient(client); // ..and the client.

    await doStuff();

  }
  catch(err) {
    console.error(err);
    process.exit();
  };

}

connect();

After that you can declare collections:

collections/Users.js

const Mongo = require('meteor-mongodb-collections');
const Users = new Mongo.Collection("users");

module.exports = Users;

And use them:

doStuff.js

const Users = require('./collections/Users.js');

async function doStuff() {
  const user = await Users.findOne({ "emails.address": "user@example.com" });
  console.log(user);

  const updateOp = await Users.update({
    "emails.address": "user@example.com"
  }, {
    $set: {
      "foo": "bar"
    }
  });
}

module.exports = doStuff;
