If you prefer, you can use a graphical file explorer instead. Note: We'll be using shell commands to create files and directories, and navigate through them. Next, we'll create a directory for our project, navigate to it, and scaffold the files needed for the project. An integrated suite of cloud database services that allow you to address a wide variety of use cases, from transactional to analytical, from search to data visualizations. We'll use pip-the package installer for Python, which is also included with your Python installation: python -m pip install 'fastapi' 'pymongo' python-dotenv Now that we have a virtual environment, we can install the required packages. Once you’ve logged into your virtual environment, the python executable will use Version 3 automatically. ![]() This is because, on some operating systems, both Python 2 and 3 are installed. Note: You might have to run this command using the python3 executable. Source env-pymongo-fastapi-crud/bin/activate Execute the following command from the terminal: python3 -m venv env-pymongo-fastapi-crud We'll use the venv package, which comes with your Python installation. We'll use PyMongo to connect to the cluster and query data.īefore we begin, we'll create a virtual Python environment to isolate the project from the rest of the globally-installed Python packages. It's cloud-based and you can create a free account and cluster in minutes, without installing anything on your machine. MongoDB Atlas is MongoDB's database-as-a-service platform. We'll be storing the books in a MongoDB Atlas cluster. It also generates a Swagger API documentation that we'll put to use when testing the application. It's a lightweight, modern, and easy-to-use framework for building APIs. To build the API, we'll use the FastAPI framework. DELETE /book/: to delete a book by its ID.The CRUD operations will be available through a REST API. That's why we'll code the most trivial, yet useful, backend application-a CRUD app for managing books. My favorite way to learn new technologies is by building something. 1 day ago &0183 &32 Where Is MongoDB Standing Right Now With a volume of 386,656, the price of MDB is down -2.01 at 410.55. MongoDB is a well known NoSQL Database that is widely used, but using its raw API can be cumbersome as you need to express your entities and your queries as a. ![]()
