What problem does it solve?

Building modern, interactive web applications in Python often involves complex JavaScript frameworks or intricate API designs. FastHTML simplifies this by enabling you to create dynamic, server-rendered hypermedia applications using Python, HTMX, and Starlette, reducing the need for extensive frontend JavaScript.

Core Features & Use Cases

  • HTML-First Development: Define HTML elements directly in Python using FastTags, making your backend code responsible for rendering dynamic UI.
  • Seamless HTMX Integration: Leverage HTMX attributes directly within your Python-generated HTML for partial page updates and interactive features without writing custom JavaScript.
  • Simplified Form & Data Handling: Automatically parse form data into Python objects using type annotations, streamlining CRUD operations and data validation.
  • Use Case: Imagine you need to build a simple todo list application with real-time updates and interactive forms. This skill allows you to define your entire UI and backend logic in Python, using HTMX for dynamic interactions like adding, editing, or deleting todos, and websockets for instant updates, all with minimal JavaScript.

Quick Start

Create a minimal FastHTML application that displays "Hello World" on the homepage.
