What is @types/mongodb?
@types/mongodb provides TypeScript definitions for the MongoDB Node.js driver, allowing developers to use MongoDB with type safety and autocompletion in TypeScript projects.
What are @types/mongodb's main functionalities?
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);
Other packages similar to @types/mongodb
mongoose
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.
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
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.
Installation
npm install --save @types/mongodb
