Leveraging mongo-triggers for automation

I just completed the installation of mongo-triggers by running:

npm install mongo-triggers

Now, I'm attempting to set up a simple "hello world" example:

var MongoClient = require('mongodb').MongoClient;
var triggers = require("mongo-triggers");

MongoClient.connect('mongodb://localhost:27017/mydatabase', function(err, db) {
  triggers(db.mycollection).insert(function(document, next) {
    console.log("Triggered on insert");
    next();
    });
});

But when I try to run it, I encounter this error message:

TypeError: Cannot read property 'save' of undefined

As I'm not very familiar with JavaScript, I may have overlooked something. Any assistance would be greatly appreciated.

Answer №1

Swap out the var MongoClient = require('mongodb').MongoClient; require("mongo-triggers");

Switch to var MongoClient = require('mongodb').MongoClient; var triggers = require("mongo-triggers");

Answer №2

After successfully resolving the initial issue, I have included the complete working code solution below:

var MongoClient = require('mongodb').MongoClient;
var triggers = require("mongo-triggers");

MongoClient.connect('mongodb://localhost:27017/mydatabase', function(err, db) {
  var myCollection = db.collection('mycollection');
  triggers(myCollection).insert(function(document, next) {
    console.log("Triggered on insert");
    next();
  });
});

However, a new challenge has arisen. Upon inserting data into the database using CLI as shown below:

> use mydatabase
> db.mycollection.insert({"mytest": 1})

No trigger is activated (no output displayed on stdout). It seems like I will need to create a separate post to address this issue.
