Combatting Alert Fatigue by Prioritizing Malicious Intent
In 2023, data breaches surged 78% from zero-day and supply chain attacks, but developers are still buried under alerts that are unable to prevent these threats.

Stub TypeScript definitions entry for mongodb, which provides its own types definitions
@types/mongodb provides TypeScript definitions for the MongoDB Node.js driver, allowing developers to use MongoDB with type safety and autocompletion in TypeScript projects.
Connecting to MongoDB
This feature allows you to connect to a MongoDB database using the MongoClient class. The code sample demonstrates how to establish a connection and handle it properly.
const { MongoClient } = require('mongodb');
const uri = 'your_mongodb_uri';
const client = new MongoClient(uri, { useNewUrlParser: true, useUnifiedTopology: true });
async function run() {
try {
await client.connect();
console.log('Connected to MongoDB');
} finally {
await client.close();
}
}
run().catch(console.dir);
CRUD Operations
This feature allows you to perform CRUD (Create, Read, Update, Delete) operations on a MongoDB collection. The code sample demonstrates how to insert, find, update, and delete documents.
const { MongoClient } = require('mongodb');
const uri = 'your_mongodb_uri';
const client = new MongoClient(uri, { useNewUrlParser: true, useUnifiedTopology: true });
async function run() {
try {
await client.connect();
const database = client.db('sample_db');
const collection = database.collection('sample_collection');
// Create
const doc = { name: 'Alice', age: 25 };
const result = await collection.insertOne(doc);
console.log(`New document created with the following id: ${result.insertedId}`);
// Read
const query = { name: 'Alice' };
const user = await collection.findOne(query);
console.log(user);
// Update
const updateDoc = { $set: { age: 26 } };
const updateResult = await collection.updateOne(query, updateDoc);
console.log(`Matched ${updateResult.matchedCount} document and modified ${updateResult.modifiedCount} document`);
// Delete
const deleteResult = await collection.deleteOne(query);
console.log(`Deleted ${deleteResult.deletedCount} document`);
} finally {
await client.close();
}
}
run().catch(console.dir);
Indexing
This feature allows you to create indexes on collections to improve query performance. The code sample demonstrates how to create an index on the 'name' field of a collection.
const { MongoClient } = require('mongodb');
const uri = 'your_mongodb_uri';
const client = new MongoClient(uri, { useNewUrlParser: true, useUnifiedTopology: true });
async function run() {
try {
await client.connect();
const database = client.db('sample_db');
const collection = database.collection('sample_collection');
// Create an index on the 'name' field
const indexName = await collection.createIndex({ name: 1 });
console.log(`Index created: ${indexName}`);
} finally {
await client.close();
}
}
run().catch(console.dir);
Mongoose is an Object Data Modeling (ODM) library for MongoDB and Node.js. It provides a higher-level abstraction over the MongoDB driver, including schema validation, middleware, and more. Unlike @types/mongodb, which provides type definitions, Mongoose offers a more opinionated and feature-rich approach to interacting with MongoDB.
The 'mongodb' package is the official MongoDB driver for Node.js. It provides a lower-level API for interacting with MongoDB databases. While @types/mongodb provides TypeScript definitions for this driver, the 'mongodb' package itself is the core library used for database operations.
Typegoose is a TypeScript library that allows you to define Mongoose models using TypeScript classes. It combines the features of Mongoose with TypeScript's type safety. Typegoose provides a more integrated experience for TypeScript developers compared to using @types/mongodb with the MongoDB driver.
This is a stub types definition for @types/mongodb (https://github.com/mongodb/node-mongodb-native).
mongodb provides its own type definitions, so you don't need @types/mongodb installed!
