Antheia
=======

[](#antheia)

A server-rendered PHP UI framework for building component-based web applications.

Antheia is a server-side UI framework for PHP that provides structured, reusable components while preserving full control over rendered HTML. It is built for applications that value predictability, testability, and long-term maintainability over client-side complexity.

> ⚠️ Antheia 3.x introduces namespace and package structure changes and is not backward compatible with 2.x.x releases. Please review the [upgrade guide](UPGRADE-3.0.md) before upgrading.

Why Antheia?
------------

[](#why-antheia)

Antheia is designed for applications that need structured, reusable user interfaces without adopting a full client-side framework.

It is a good fit when:

- You want **server-rendered pages** with a consistent, component-based layout
- You prefer **server-side UI composition in PHP** over full client-side SPA frameworks
- You need **predictable HTML output** that is easy to test end-to-end
- You want to avoid the complexity and build pipelines required by SPA frameworks
- You value **long-term stability**, explicit versioning, and controlled breaking changes
- Your application benefits from **progressive enhancement** rather than full client-side rendering

Antheia focuses on clarity, testability, and maintainability, while remaining flexible enough to integrate into existing PHP applications.

A live example of the interface (based on the current major version) is available at [antheia.voipit.ro](https://antheia.voipit.ro).
The demo uses the content from the `examples` folder.

Please check the [project wiki](https://github.com/cosminstaicu/antheia/wiki) for more details about the library.

Antheia is used in production by the Cloud PBX service **Accolades**, provided by [VoIPIT Romania](https://www.voipit.ro).

Who Antheia is NOT for
----------------------

[](#who-antheia-is-not-for)

Antheia may not be a good fit if:

- You are building a **fully client-side SPA** where most logic and rendering live in the browser
- You expect **real-time UI state management** similar to React, Vue, or Angular
- You want a framework that hides or abstracts away HTML structure
- Your project relies heavily on **frontend build pipelines** and JavaScript-first tooling
- You are looking for a drop-in theme or CMS rather than a UI framework

Antheia is intentionally opinionated toward server-rendered applications with explicit structure and behavior.

Features
--------

[](#features)

- Server-rendered component architecture
- Reusable PHP UI components
- Predictable HTML output
- End-to-end testing support
- Progressive enhancement friendly
- Minimal frontend build requirements
- Explicit versioning and migration policy

Installation
------------

[](#installation)

Use [composer](https://getcomposer.org) to install Antheia into your project:

```
composer require antheia/framework
```

After installation, you must configure a cache folder for Antheia before rendering any pages.

The cache folder:

- must be writable by the application
- must have a corresponding public URL
- should not be publicly writable beyond what Antheia requires

You can configure it at runtime using:

```
Globals::setCache(string $url, string $path);
```

The `$url` must point to the public URL of the cache directory, while `$path` must be the absolute filesystem path.

Failing to configure the cache correctly will result in runtime errors. This requirement exists to allow Antheia to generate cached assets deterministically.
