Flask Api Development

This one gets you building Flask REST APIs the right way from the start. It covers the practical stack you'd actually use: blueprints for keeping routes organized, SQLAlchemy for database work, JWT for auth, and proper request validation. The quick start shows a real app structure with error handlers and middleware, not just hello world. What I like is the focus on production concerns like environment config, error handling that doesn't leak stack traces, and pagination for collections. If you're spinning up a microservice or need a lightweight API without Django's overhead, this gives you the patterns to avoid the common Flask mistakes.

Overview

Create efficient Flask APIs with blueprints for modular organization, SQLAlchemy for ORM, JWT authentication, comprehensive error handling, and proper request validation following REST principles.

When to Use

Building RESTful APIs with Flask
Creating microservices with minimal overhead
Implementing lightweight authentication systems
Designing API endpoints with proper validation
Integrating with relational databases
Building request/response handling systems

Quick Start

Minimal working example:

# app.py
from flask import Flask, request, jsonify
from flask_cors import CORS
from flask_sqlalchemy import SQLAlchemy
from flask_jwt_extended import JWTManager
import os

app = Flask(__name__)
app.config['SQLALCHEMY_DATABASE_URI'] = os.getenv('DATABASE_URL', 'sqlite:///app.db')
app.config['JWT_SECRET_KEY'] = os.getenv('JWT_SECRET_KEY', 'dev-secret')
app.config['JSON_SORT_KEYS'] = False

db = SQLAlchemy(app)
jwt = JWTManager(app)
CORS(app)
