Build a Flask Fullstack App with MongoDB

Flask is a lightweight web framework for Python that is easy to use and great for building web applications. MongoDB is a NoSQL database that is highly scalable and flexible. In this tutorial, we will show you how to build a fullstack application using Flask and MongoDB.

Step 1: Set up your development environment

First, make sure you have Python installed on your system. You can download it from the official Python website. Next, install Flask by running the following command in your terminal:

pip install Flask

Next, install PyMongo, which is a Python driver for MongoDB, by running the following command:

pip install pymongo

Step 2: Create a Flask app

Create a new directory for your project and navigate into it. Create a new Python file for your Flask app, for example app.py, and add the following code:

        from flask import Flask

        app = Flask(__name__)

        @app.route('/')
        def index():
            return 'Hello World!'

        if __name__ == '__main__':
            app.run()
    

Step 3: Set up MongoDB

Next, you need to set up a MongoDB database. You can download MongoDB from the official website and follow the installation instructions. Once MongoDB is set up, you can connect to it in your Flask app by using PyMongo:

        from pymongo import MongoClient

        client = MongoClient('mongodb://localhost:27017/')
        db = client['mydatabase']
    

Step 4: Build your fullstack app

Now that you have set up your development environment, created your Flask app, and set up MongoDB, you can start building your fullstack application. You can create routes in your Flask app to handle different endpoints and interact with your MongoDB database to store and retrieve data.

By following these steps, you can build a fullstack application using Flask and MongoDB. This tutorial provides a basic overview of how to get started, but there are endless possibilities for what you can achieve with these tools. Have fun building your app!
