MongoDB Drivers for Node.js
NodeJS renders the javascript code out of the browser, which enables developers to build applications for desktop and servers. Node.js is built on Google Chrome’s V8 JavaScript engine and use an event-driven, non-blocking I/O model. Using NodeJs with Mongodb can be a good choice for developers due to its JSON like syntax. You can add the driver to your application to work with MongoDB in JavaScript.
Key Features
- Asynchronus Operations: It utilised NodeJS’s asynchronus nature for efficient I/O operations.
- BSON Support: BSON (Binary JSON) is the binary-encoded format and it is used to serialize documents for storage and data sharing.
Code Example
Javascript
// Import the MongoClient class from the 'mongodb' package const { MongoClient } = require( 'mongodb' ); // MongoDB connection URI. Replace '<username>' and '<password>' with actual credentials. const uri = 'mongodb+srv://<username>:<password>@cluster0.mongodb.net/test' ; // Create a new instance of MongoClient with the connection URI and options const client = new MongoClient(uri, { useNewUrlParser: true }); // Define an asynchronous function named 'run' async function run() { try { // Connect to the MongoDB server using the MongoClient instance await client.connect(); // If the connection is successful, log a message indicating the successful connection console.log( 'Connected to the database' ); } finally { // Whether the connection succeeds or fails, close the MongoClient connection await client.close(); } } // Call the 'run' function and handle any errors using the 'catch' method run(). catch (console.error); |
If database is successfully connected then the output will be shown as:
Connected to the database.
MongoDB Drivers For Different Languages
MongoDB is a NoSQL database that is widely used for storing and managing both complex and larger data. For good integration between applications and the MongoDB database, it provides drivers that allow the developer to interact with the database using the programming language of their choice. In this article, we will see different drivers of MongoDB which are popularly used.
Programming Languages supported by MongoDB are C, C++, C#, Go, Java, Kotlin, Node.js, PHP, Python, Ruby, Rust, Scala, and Swift. We will understand each one of them more easily along with their code implementation
