Building a RESTful API Using Flask and MongoDB
This tutorial guides you through creating a RESTful API using Flask and MongoDB. You will learn how to set up endpoints for GET, POST, PUT, and DELETE requests to perform CRUD operations on a MongoDB collection.
1. Introduction to APIs
An API (Application Programming Interface) allows two systems to communicate and exchange data. REST (Representational State Transfer) is an architecture style for designing networked applications. REST APIs are widely used for creating web services due to their simplicity, scalability, and statelessness.
2. Why Flask?
Flask is a lightweight web framework in Python that is excellent for creating APIs due to its simplicity and flexibility. Paired with MongoDB, a NoSQL database, Flask allows you to build scalable, data-driven applications.
3. Prerequisites
Before we begin, make sure you have the following installed:
Python 3.x: Flask is a Python-based framework.
MongoDB: A NoSQL database for storing data.
Pip: Python package installer for Flask and pymongo libraries.
You can install Flask and PyMongo using the following commands:
bash
bash
pip install Flask pymongo
4. Setting Up the Project
Create a new directory for your project and initialize it with the following structure:
my_flask_api/
├── app.py
└── requirements.txt
app.py: This will contain your Flask app code.
requirements.txt: For managing dependencies (like Flask, pymongo).
