Artanis Tutorial: Building a Blog API

Welcome to the comprehensive Artanis tutorial! In this step-by-step guide, we'll build a complete Blog API from scratch, covering all the essential concepts you need to master Artanis.

What You'll Learn

By the end of this tutorial, you'll understand:

  • ✅ Project Setup - Creating and organizing an Artanis project
  • ✅ Route Creation - Defining endpoints and handling different HTTP methods
  • ✅ Middleware - Adding logging, authentication, and error handling
  • ✅ Database Integration - Connecting to and managing data
  • ✅ Request Validation - Validating and sanitizing input data
  • ✅ Code Organization - Using routers for modular applications

What We'll Build

Our Blog API will include:

  • 📝 Post Management: Create, read, update, and delete blog posts
  • 👤 User Authentication: Register users and manage sessions
  • 🔒 Authorization: Protect endpoints based on user permissions
  • ✅ Data Validation: Ensure data integrity with validation middleware
  • 📊 Request Logging: Track API usage and performance
  • 🛡️ Error Handling: Graceful error responses with proper HTTP status codes

Prerequisites

Before starting, make sure you have:

  • Python 3.8+ installed
  • Basic Python knowledge (async/await, classes, functions)
  • HTTP/REST API concepts (GET, POST, PUT, DELETE)
  • Artanis installed: pip install artanis uvicorn[standard]

New to Python async/await?

If you're new to asynchronous Python, don't worry! The tutorial explains async concepts as we go. You can also check out the Python async/await documentation.

Tutorial Structure

The tutorial is divided into 6 progressive chapters:

  • Project Setup

    Set up your development environment and create the basic project structure

    Topics: Virtual environments, project structure, basic app setup

  • Creating Routes

    Learn how to define routes and handle different HTTP methods

    Topics: Route registration, path parameters, request/response handling

  • Middleware

    Add powerful middleware for logging, CORS, and error handling

    Topics: Global middleware, path-based middleware, custom middleware

  • Database Integration

    Connect to a database and implement data persistence

    Topics: Database setup, models, CRUD operations

  • Request Validation

    Validate and sanitize incoming request data

    Topics: Input validation, error responses, data sanitization

  • Routers

    Organize your code with modular routers and subrouting

    Topics: Router classes, subrouting, code organization
