Unlocking the Power of Tetra: A Full-Stack Framework

What is Tetra?

Tetra is a full-stack framework built on top of Django and Alpine.js. It enables developers to write Python, HTML, CSS, and JavaScript code in a unified location, reducing complexity and increasing productivity. Tetra’s core functionality revolves around the concept of components, which are self-contained units of code that handle specific tasks.

The Tetra Component

A Tetra component is a single Python file that contains all the necessary code for a specific feature or functionality. This includes HTML templates, CSS styles, JavaScript logic, and Python backend code. Components can be dependent or independent, allowing for flexible and modular development.

# Example of a Tetra component
from tetra import component

@component
def MyComponent:
    # HTML template
    template = '''
        <div>
            <h1>My Component</h1>
        </div>
    '''

    # CSS styles
    styles = '''
        h1 {
            color: blue;
        }
    '''

    # JavaScript logic
    script = '''
        console.log('Hello from MyComponent!');
    '''

    # Python backend code
    def backend(self):
        return {'message': 'Hello from backend!'}

Building a Tetra Blog App

To demonstrate the power of Tetra, we’ll build a simple blog application that performs CRUD (Create, Read, Update, Delete) operations. Our app will have the following features:

• Create new blog posts
• Display a list of all blog posts
• Edit existing blog posts
• Delete blog posts

We’ll create several Tetra components to handle these features, including:

• AddPost: handles creating new blog posts
• PostItem: displays a single blog post
• ViewPosts: displays a list of all blog posts
• PostDetail: displays a detailed view of a single blog post
• UpdatePost: handles editing existing blog posts

# Example of AddPost component
from tetra import component

@component
def AddPost:
    # HTML template
    template = '''
        <form>
            <input type="text" name="title">
            <textarea name="content"></textarea>
            <button>Create Post</button>
        </form>
    '''

    # JavaScript logic
    script = '''
        const form = document.querySelector('form');
        form.addEventListener('submit', (e) => {
            e.preventDefault();
            // Create new blog post logic
        });
    '''

    # Python backend code
    def backend(self):
        # Create new blog post logic
        pass

Notes on Tetra’s Production-Readiness

While Tetra shows great promise, it’s still in its early stages of development. The framework currently supports Python 3.9 and above, but the team is working to expand compatibility to older versions. Additionally, the documentation is still evolving and may require some trial and error to navigate.
