Learn how to build API easily! This web API development guide covers backend programming fundamentals to create simple and functional APIs. Start building now!
APIs are super important these days. They're like the secret language that lets different apps talk to each other. Want to learn how to build one? It's easier than you think! This guide will show you how to create a simple web API from scratch. We'll cover the basics, so you can start building your own APIs. We will focus on RESTful APIs. They are the most common way to build APIs.
Why should you care about building APIs? Good question!
Before we start, you should know a few things:
You can use different tools to build APIs. Here are some popular choices:
We'll use Python with Flask. It's simple and easy to use.
python3 -m venv venv source venv/bin/activate # On Linux/macOS .\venv\Scripts\activate # On Windows
pip install flask
We'll create an API for managing books. It will do these things:
Here's the Python code:
from flask import Flask, jsonify, request app = Flask(name) books = [ {"id": 1, "title": "The Lord of the Rings", "author": "J.R.R. Tolkien"}, {"id": 2, "title": "Pride and Prejudice", "author": "Jane Austen"}, {"id": 3, "title": "1984", "author": "George Orwell"} ] @app.route('/books', methods=['GET']) def get_books(): return jsonify(books) @app.route('/books/', methods=['GET']) def get_book(id): book = next((book for book in books if book['id'] == id), None) if book: return jsonify(book) return jsonify({'message': 'Book not found'}), 404 @app.route('/books', methods=['POST']) def create_book(): data = request.get_json() new_book = { 'id': len(books) + 1, 'title': data['title'], 'author': data['author'] } books.append(new_book) return jsonify(new_book), 201 @app.route('/books/', methods=['PUT']) def update_book(id): book = next((book for book in books if book['id'] == id), None) if book: data = request.get_json() book['title'] = data['title'] book['author'] = data['author'] return jsonify(book) return jsonify({'message': 'Book not found'}), 404 @app.route('/books/', methods=['DELETE']) def delete_book(id): global books # Access the global 'books' list books = [book for book in books if book['id'] != id] return jsonify({'message': 'Book deleted'}) if name == 'main': app.run(debug=True)
What's going on here?
Flask
, jsonify
, and request
. These help us build the API.@app.route()
to say what each part of the API does.app.py
.python app.py
curl http://localhost:5000/books
curl http://localhost:5000/books/1
curl -X POST -H "Content-Type: application/json" -d '{"title": "The Hitchhiker's Guide to the Galaxy", "author": "Douglas Adams"}' http://localhost:5000/books
curl -X PUT -H "Content-Type: application/json" -d '{"title": "The Fellowship of the Ring", "author": "J.R.R. Tolkien"}' http://localhost:5000/books/1
curl -X DELETE http://localhost:5000/books/1
