           2. Grant of Copyright License. Subject to the terms and conditions of
              this License, each Contributor hereby grants to You a perpetual,
              worldwide, non-exclusive, no-charge, royalty-free, irrevocable
              copyright license to reproduce, prepare Derivative Works of,

              Contribution embodied in the Work constitutes direct or contributory
              patent infringement, then any patent licenses granted to You under
              this License for that Work shall terminate as of the date such
              litigation is filed.
        
           4. Redistribution. You may reproduce and distribute copies of the
              Work or Derivative Works thereof in any medium, with or without
              modifications, and in Source or Object form, provided that You
              meet the following conditions:
        
              (a) You must give any other recipients of the Work or Derivative
                  Works a copy of this License; and
        
              (b) You must cause any modified files to carry prominent notices
                  stating that You changed the files; and
        
              (c) You must retain, in the Source form of any Derivative Works

                  attribution notices from the Source form of the Work,
                  excluding those notices that do not pertain to any part of
                  the Derivative Works; and
        
              (d) If the Work includes a "NOTICE" text file as part of its
                  distribution, You must include a readable copy of the
                  attribution notices contained within such NOTICE file, in
                  at least one of the following places: within a NOTICE text
                  file distributed as part of the Derivative Works; within
                  the Source form or documentation, if provided along with the
                  Derivative Works; or, within a display generated by the
                  Derivative Works, if and wherever such third-party notices
                  normally appear. The contents of the NOTICE file are for
                  informational purposes only and do not modify the License.
                  You may add Your own attribution notices within Derivative
                  Works that You distribute, alongside or in addition to the
                  NOTICE text from the Work, provided that such additional
                  attribution notices cannot be construed as modifying the
                  License.
        
              You may add Your own license statement for Your modifications and
              may provide additional grant of rights to use, copy, modify, merge,
              publish, distribute, sublicense, and/or sell copies of the Work,
              subject to the terms and conditions of this License.
        
           5. Submission of Contributions. Unless You explicitly state otherwise,

              origin of the Work and reproducing the content of the NOTICE file.
        
           7. Disclaimer of Warranty. Unless required by applicable law or
              agreed to in writing, Licensor provides the Work (and each
              Contributor provides its Contributions) on an "AS IS" BASIS,
              WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
              implied, including, without limitation, any warranties or conditions

              appropriateness of using or reproducing the Work and assume any
              risks associated with Your exercise of permissions under this License.
        
           8. Limitation of Liability. In no event and under no legal theory,
              whether in tort (including negligence), contract, or otherwise,
              unless required by applicable law (such as deliberate and grossly
              negligent acts) or agreed to in writing, shall any Contributor be
              liable to You for damages, including any direct, indirect, special,
              incidental, or exemplary damages of any character arising as a
              result of this License or out of the use or inability to use the
              Work (including but not limited to damages for loss of goodwill,
              work stoppage, computer failure or malfunction, or all other
              commercial damages or losses), even if such Contributor has been
              advised of the possibility of such damages.
        
           9. Accepting Warranty or Additional Liability. While redistributing
              the Work or Derivative Works thereof, You may choose to offer,
              and charge a fee for, acceptance of support, warranty, indemnity,

              License. However, in accepting such obligations, You may offer only
              conditions that are consistent with this License.
        
           END OF TERMS AND CONDITIONS

## What is hotframe

hotframe is a Python web framework that unifies FastAPI, SQLAlchemy 2.0, Jinja2, HTMX, and Alpine.js under Django-like ergonomics. It adds a hot-mount module engine — load and unload plugins at runtime without restarting the process — and a Turbo/Livewire-style HTMX layer for server-driven UI. Built for teams who want the productivity of Rails or Django with the async performance of FastAPI.

---

## Quickstart

```
pip install hotframe
```

```
hf startproject myapp
cd myapp
hf runserver
```

```
INFO     hotframe.core - Loading kernel modules...
INFO     hotframe.modules - Mounted: core, auth, admin (3 modules)
INFO     hotframe.server - Uvicorn running on http://127.0.0.1:8000
INFO     hotframe.server - Press CTRL+C to quit
```

The CLI installs two aliases: `hf` (short) and `hotframe` (explicit).

---

## Key Features

- **Hot-mount dynamic modules** — Load and unload Python modules at runtime via a DB registry with topological dependency resolution. No process restart required.

- **HTMX layer (Turbo/Livewire-style)** — `@htmx_view` decorator, named frames, TurboStream responses, out-of-band swaps, and server-sent event broadcasting. Build rich UIs without writing JavaScript.

- **Django-like ergonomics** — `AppConfig`, `settings.py`, management commands, scaffolding CLI. Familiar conventions so teams onboard in minutes, not days.

- **AsyncEventBus + HookRegistry** — WordPress-style actions and filters across modules. Decouple features without tight imports. Fully async-native.

- **SQLAlchemy 2.0 + Alembic** — Async sessions, per-module migration namespaces, and automatic migration discovery. No shared migration root.

- **Jinja2 + Alpine.js integration** — Template inheritance, context processors, CSP-safe nonce injection, and Alpine.js wired out of the box.

- **OpenTelemetry observability** — Traces, metrics, and structured logs built into the request lifecycle. Zero extra setup for OTLP exporters.

- **CLI scaffolding** — `hf startproject`, `hf startapp`, `hf startmodule`, `hf makemigrations`, `hf migrate`. Generate production-ready skeletons from the command line.

## Minimal Example

Define a module with a model, a route, and a template in under 20 lines:

```python
# modules/blog/module.py
from hotframe.modules import ModuleConfig

class BlogModule(ModuleConfig):
    name = "blog"
    version = "1.0.0"
    dependencies = ["core", "auth"]
```

```python
# modules/blog/models.py
from hotframe.db import Base
from sqlalchemy.orm import Mapped, mapped_column

class Post(Base):
    __tablename__ = "blog_posts"
    id: Mapped[int] = mapped_column(primary_key=True)
    title: Mapped[str]
    body: Mapped[str]
```

```python
# modules/blog/views.py
from hotframe.htmx import htmx_view
from hotframe.routing import router
from .models import Post

@router.get("/blog")
@htmx_view(template="blog/index.html")
async def post_list(request):
    posts = await Post.all()
    return {"posts": posts}
```

```html
<!-- modules/blog/templates/blog/index.html -->
<div hx-get="/blog" hx-trigger="every 30s" hx-swap="innerHTML">
  {% for post in posts %}
    <article>{{ post.title }}</article>
  {% endfor %}
</div>
```

Mount it:

```python
# settings.py
INSTALLED_MODULES = ["core", "auth", "blog"]
```

---

## Architecture Overview

hotframe is organized in three layers:

**Runtime layer** — the framework kernel. Boots FastAPI, wires middleware, initializes the DB engine, and exposes the public API (`@htmx_view`, `router`, `settings`, `EventBus`, `HookRegistry`).

**Module layer** — each module is a Python package with a `ModuleConfig` subclass, its own models, views, templates, migrations, and static assets. The module engine resolves dependency order, mounts routes and Alembic migration contexts, and registers hook namespaces. Modules can be installed, uninstalled, enabled, and disabled at runtime via the admin API without touching the running process.

**HTMX layer** — sits on top of FastAPI responses. The `@htmx_view` decorator detects `HX-Request` headers and returns partial renders or full-page responses automatically. TurboStream helpers produce `text/vnd.turbo-stream.html` responses for out-of-band DOM updates. The `EventBus` integrates with server-sent events for real-time broadcasting to named HTMX frames.

The CLI (`hf`) is a Typer application that wraps Uvicorn, Alembic, and the scaffolding generators. It reads `settings.py` from the project root and discovers modules from `INSTALLED_MODULES`.
