Legacy support of MongoDB for Node.js

CAST supports MongoDB via its com.castsoftware.nodejs extension. Details about the support provided for Node.js source code is discussed below.

WARNING: This documentation page is for com.castsoftware.nodejs from 2.10.x - 2.12.x. If you need to view documentation for more recent releases see here.

Supported Libraries

The following libraries are supported:

Library	require	Versions
MongoDB	mongodb	1.2 to 8.x
Mongoose	mongoose	5.x to 8.x
Prisma	@prisma/client	2.x to 6.x

Objects

Icon	Description
	NodeJS MongoDB connection
	NodeJS unknown MongoDB connection
	NodeJS MongoDB collection

Supported MongoDB

Supported links

Link Type	Source and destination of link	Supported APIs
useInsertLink	Between JavaScript Function (JavaScript Initialisation also) and Node.js MongoDB collection	db.collection.insertMany
useUpdateLink	Between JavaScript Function (JavaScript Initialisation also) and Node.js MongoDB collection	db.collection.findOneAndUpdate db.collection.findOneAndReplace db.collection.replaceOne db.collection.updateOne db.collection.updateMany
useDeleteLink	Between JavaScript Function (JavaScript Initialisation also) and Node.js MongoDB collection	db.collection.findOneAndDelete db.collection.deleteOne db.collection.deleteMany db.collection.remove
useSelectLink	Between JavaScript Function (JavaScript Initialisation also) and Node.js MongoDB collection	db.collection.find db.collection.findOne

Example

Taking the following codes:

var MongoClient = require('mongodb').MongoClient

var url = 'mongodb://localhost:27017/myproject';

var insertDocuments = function(db, callback) {
  var collection = db.collection('documents');
  collection.insertMany([
    {a : 1}, {a : 2}, {a : 3}
  ], function(err, result) {
    callback(result);
  });
}

var updateDocument = function(db, callback) {
  var collection = db.collection('documents');
  for (i = 0; i < 2; i += 1) {
	collection.updateOne({ a : 2 }
	  , { $set: { b : 1 } }, function(err, result) {
	  callback(result);
	});
  }
}

MongoClient.connect(url, function(err, db) {
  insertDocuments(db, function() {
    updateDocument(db, function() {
      db.close();
    });
  });
});

In this example, a ‘NodeJS MongoDB connection’ and a ‘NodeJS MongoDB collection’ objects are created. This extension creates a useInsert link from function ‘insertDocuments’ to the collection ‘documents’ and a useUpdate link from function ‘updateDocument’ to the collection ‘documents’:

Supported Mongoose

Supported links

Link Type	Source and destination of link	Supported APIs
useInsertLink	Between JavaScript Function (JavaScript Initialisation also) and Node.js MongoDB collection	model.create model.insertMany
useUpdateLink	Between JavaScript Function (JavaScript Initialisation also) and Node.js MongoDB collection	model.findByIdAndUpdate model.findOneAndUpdate model.findOneAndReplace model.replaceOne model.updateOne model.updateMany
useDeleteLink	Between JavaScript Function (JavaScript Initialisation also) and Node.js MongoDB collection	model.deleteOne model.deleteMany model.findByIdAndDelete model.findOneAndDelete
useSelectLink	Between JavaScript Function (JavaScript Initialisation also) and Node.js MongoDB collection	model.exists model.find model.findOne model.findById model.where

Example

Taking the following codes:

var mongoose = require('mongoose');

mongoose.connect('mongodb://localhost/analyzerlauncher', function(err) {
  if (err) { throw err; }
});

userModel = mongoose.model('users', userSchema);

function find(req,res) {
  userModel.findOne(req.params.id, function (err, authorize) {})
}

In this example, a ‘NodeJS MongoDB connection’ and a ‘NodeJS MongoDB collection’ objects are created. This extension creates a useSelect link from function ‘find’ to the collection ‘users’:
