fastTEA: Build Elegant Web Applications in Python

fastTEA is a powerful and intuitive Python framework for building web applications with ease. Inspired by The Elm Architecture (TEA), fastTEA brings simplicity and predictability to your Python web development workflow.

Features

• Simple and Intuitive: Build web apps using a clear, archtectural approach.
• Based on The Elm Architecture: Benefit from a time-tested, scalable architecture.
• FastAPI Backend: Leverage the speed and simplicity of FastAPI.
• HTMX Integration: Create dynamic UIs without writing JavaScript.
• Flexible CSS Framework Support: Choose from Pico, Bootstrap, or Tailwind CSS.
• Type Safety: Utilizes Pydantic for robust data validation.

Installation

Install fastTEA using pip:

pip install fasttea-web

Quick Start

Let's dive into a simple "Hello, World!" application to showcase the power and simplicity of fastTEA.

from fasttea import FastTEA, Model, Msg, Cmd, Element, CSSFramework
from fasttea.html import div, h1, input_, button, p

class AppModel(Model):
    name: str = ""
    greeting: str = ""

app = FastTEA(AppModel(), css_framework=CSSFramework.PICO)

@app.update
def update(msg: Msg, model: AppModel) -> tuple[AppModel, Cmd | None]:
    if msg.action == "greet":
        model.name = msg.value
        model.greeting = f"Hello {msg.value}!"
    return model, None

@app.view
def view(model: AppModel) -> Element:
    return div({},
        h1({}, "FastTEA Hello Example"),
         input_({
                "id": "input",
                "type": "text",
                "value": model.name,
                "name": "name",
                "placeholder": "Enter your name"
        }, ""),
        button({
                "onClick": "greet",
                "getValue": "input"
        },"Greet"),
        p ({}, model.greeting)
    )

if __name__ == "__main__":
    app.run()

Core Principles Explained

1. Model: The AppModel class defines the application's state. In this example, it stores the user's name and the greeting message.

2. Update: The update function handles state changes based on messages. It takes the current model and a message, then returns the updated model and any commands to be executed.

3. View: The view function renders the UI based on the current model state. It returns a tree of Element objects that fastTEA converts to HTML.

4. HTMX Integration: fastTEA leverages HTMX for dynamic updates without writing JavaScript. The button in our example uses HTMX attributes to trigger a server request.

5. CSS Framework: fastTEA supports various CSS frameworks. In this example, we're using Pico CSS for a clean, minimal design.

Coming Soon!

We're constantly working to improve fastTEA and add new features. Here's a sneak peek at what's coming:

1. More Examples: We're developing a variety of examples to showcase fastTEA's capabilities in different scenarios.

2. Simple Chatbot: A demonstration of how to implement a basic chatbot using fastTEA, showing off its real-time update capabilities.

3. Form Processing: Enhanced support for handling and processing form submissions, making it even easier to create data-entry applications.

4. Client-Side Commands: Introducing a way to define commands that can be executed locally in the browser, improving responsiveness and reducing server load for certain operations.

5. Server-Triggered Commands: Allowing the server to trigger these client-side commands, enabling more complex interactions between the server and client.

6. UiBubbles and CmdBubbles: More structure.

These upcoming features will make fastTEA even more powerful and flexible, opening up new possibilities for your web applications. Stay tuned for updates!
