C++ MongoDB

Introduction to mongocxx

The mongocxx driver is the official MongoDB C++ driver, providing a modern C++ API for interacting with MongoDB databases. It is built on top of libmongoc and bsoncxx libraries, offering both synchronous and asynchronous interfaces.

In this guide, we'll walk through setting up a C++ application to interact with MongoDB using the mongocxx driver, focusing on document-based data operations.

Installing mongocxx

To use mongocxx, you need to install the driver and its dependencies. Follow these steps:

• Install the libmongoc and libbson libraries.
• Download the mongocxx source code from the official MongoDB GitHub repository.
• Build and install mongocxx using cmake and make.

Connecting to MongoDB

Once the driver is installed, you can connect to a MongoDB instance. Begin by including the necessary headers and setting up a connection to your MongoDB server.

CRUD Operations

With the connection established, you can perform CRUD (Create, Read, Update, Delete) operations on your MongoDB collections. Below are examples of each operation using the mongocxx API.

Handling Errors

Error handling is crucial in database operations. The mongocxx driver provides mechanisms to handle exceptions and errors that may arise during database interactions.

Wrap your operations in try-catch blocks to manage exceptions effectively.
