Full stack component framework for Django using Alpine.js

Tetra is a new full stack component framework for Django, bridging the gap between your server logic and front end presentation. It uses a public shared state and a resumable server state to enable inplace updates. It also encapsulates your Python, HTML, JavaScript and CSS into one file for close proximity of related concerns.

What does Tetra do?

  • Django on the backend, Alpine.js in the browser

    Tetra combines the power of Django with Alpine.js to make development easier and quicker.

  • Component encapsulation

    Each component combines its Python, HTML, CSS and JavaScript in one place for close proximity of related code.

  • Resumable server state

    The components’ full server state is saved between public method calls. This state is encrypted for security.

  • Public server methods

    Methods can be made public, allowing you to easily call them from JS on the front end, resuming the component’s state.

  • Shared public state

    Attributes can be decorated to indicate they should be available in the browser as Alpine.js data objects.

  • Server “watcher” methods

    Public methods can be instructed to watch a public attribute, enabling reactive re-rendering on the server.

  • Inplace updating from the server

    Server methods can update the rendered component in place. Powered by the Alpine.js morph plugin.

  • Component library packaging

    Every component belongs to a “library”; their JS & CSS is packed together for quicker browser downloads.

  • Components with overridable blocks

    Component can have multiple {% block(s) %} which can be overridden when used.

  • JS/CSS builds using esbuild

    Both for development (built into runserver) and production your JS & CSS is built with esbuild.

  • Source Maps

    Source maps are generated during development so that you can track down errors to the original Python files.

  • Syntax highlighting with type annotations

    Tetra uses type annotations to syntax highlight your JS, CSS & HTML in your Python files with a VS Code plugin
