Flask API Development

Develop lightweight Flask APIs with routing, blueprints, database integration, authentication, and clean request/response handling. Ideal for microservices and small web services where Django would be overkill.

This skill helps you build focused Flask backends. It organizes endpoints with blueprints and an application factory, integrates SQLAlchemy for persistence, adds JWT or session authentication, validates and marshals request/response payloads, and structures the project so a small service can grow without a rewrite.

When to use

Use when building RESTful APIs, microservices, or lightweight web services with Flask — routing, blueprints, SQLAlchemy integration, authentication, and request handling.

Examples

Blueprint-based API

Structure a growing service

Create a Flask API using an application factory and blueprints for auth and items, with SQLAlchemy models and JWT-protected routes

Lightweight microservice

Stand up a small service fast

Build a minimal Flask microservice that accepts a webhook, validates the payload, and writes it to the database with proper error responses
