# FastAPI Chameleon

Adds integration of the Chameleon template language to FastAPI.

## Installation

```bash
pip install fastapi-chameleon
```

## API overview

### Setup

Point the library at your Chameleon templates folder once at app startup.

- `global_init`: Initialize the Chameleon template engine for your app

### Rendering views

Decorate FastAPI view functions to render templates, or build a response directly.

- `template`: Decorate a FastAPI view to render its return value through a Chameleon template
- `response`: Render a template and return it as a FastAPI response directly

### Error responses

Short-circuit a view to render a friendly error page with the right status code.

- `not_found`: Short-circuit the current view and render a friendly 404 page
- `generic_error`: Short-circuit the current view and render an error page with a custom status code

### Exceptions

Exception types raised by the library (the error helpers raise these internally).

- `exceptions.FastAPIChameleonException`
- `exceptions.FastAPIChameleonNotFoundException`
- `exceptions.FastAPIChameleonGenericException`
