# Async Expo Push Notifications SDK for Python

**Modern Python SDK for Expo Push Notifications with async/await support, Pydantic models, and full type hints.**

> **Note:** This is an **independent project** and is **not officially maintained by Expo**. It's a modern reimplementation with async support.

If you have problems or suggestions, please feel free to [open an issue](https://github.com/tmdgusya/async-expo-notification-sdk/issues) or submit a PR. Contributions welcome! 🙏

## Installation

```bash
pip install async-expo-push-notifications
```

> **Note:** Package name is `async-expo-push-notifications` but you still import as `exponent_server_sdk`

## Requirements

- Python 3.8+
- Type-safe with Pydantic models
- Async support with httpx
- Synchronous support with requests (backward compatible)

## Usage

Use to send push notifications to Exponent Experiences from a Python server.

[Full documentation](https://docs.expo.dev/push-notifications/sending-notifications/#http2-api) on the API is available if you want to dive into the details.

### Async/Await Usage (Recommended for modern applications)

```python
import asyncio
from exponent_server_sdk import AsyncPushClient, PushMessage

async def send_notification():
    async with AsyncPushClient() as client:
        message = PushMessage(
            to="ExponentPushToken[xxxxxxxxxxxxxxxxxxxxxx]",
            title="Hello",
            body="World!",
            data={"extra": "data"}
        )
        ticket = await client.publish(message)
        ticket.validate_response()

asyncio.run(send_notification())
```

### Synchronous Usage (Backward Compatible)

Here's an example on how to use this with retries and reporting via [pyrollbar](https://github.com/rollbar/pyrollbar).

```python
from exponent_server_sdk import (
    DeviceNotRegisteredError,
    PushClient,
    PushMessage,
    PushServerError,
    PushTicketError,
)
import os
import requests
from requests.exceptions import ConnectionError, HTTPError

# Optionally providing an access token within a session if you have enabled push security
session = requests.Session()
session.headers.update(
    {
        "Authorization": f"Bearer {os.getenv('EXPO_TOKEN')}",
        "accept": "application/json",
        "accept-encoding": "gzip, deflate",
        "content-type": "application/json",
    }
)

# Basic arguments. You should extend this function with the push features you
# want to use, or simply pass in a `PushMessage` object.
def send_push_message(token, message, extra=None):
    try:
        response = PushClient(session=session).publish(
            PushMessage(to=token,
                        body=message,
                        data=extra))
    except PushServerError as exc:
        # Encountered some likely formatting/validation error.
        rollbar.report_exc_info(
            extra_data={
                'token': token,
                'message': message,
                'extra': extra,
                'errors': exc.errors,
                'response_data': exc.response_data,
            })
        raise
    except (ConnectionError, HTTPError) as exc:
        # Encountered some Connection or HTTP error - retry a few times in
        # case it is transient.
        rollbar.report_exc_info(
            extra_data={'token': token, 'message': message, 'extra': extra})
        raise self.retry(exc=exc)

    try:
        # We got a response back, but we don't know whether it's an error yet.
        # This call raises errors so we can handle them with normal exception
        # flows.
        response.validate_response()
    except DeviceNotRegisteredError:
        # Mark the push token as inactive
        from notifications.models import PushToken
        PushToken.objects.filter(token=token).update(active=False)
    except PushTicketError as exc:
        # Encountered some other per-notification error.
        rollbar.report_exc_info(
            extra_data={
                'token': token,
                'message': message,
                'extra': extra,
                'push_response': exc.push_response._asdict(),
            })
        raise self.retry(exc=exc)
```

## Features

### 🚀 Async/Await Support

Modern async/await syntax for high-performance applications:

```python
async with AsyncPushClient() as client:
    tickets = await client.publish_multiple(messages)
```

### 🔒 Type Safety with Pydantic

All models use Pydantic for validation and type safety:

```python
# Automatic validation
message = PushMessage(
    to="ExponentPushToken[xxx]",
    priority="high",  # Validates against allowed values
    richContent={"image": "https://example.com/img.png"}  # NEW!
)
```

### 💉 Dependency Injection

Inject custom HTTP clients for testing or custom behavior:

```python
import httpx

custom_client = httpx.AsyncClient(
    headers={"Authorization": f"Bearer {token}"}
)
push_client = AsyncPushClient(http_client=custom_client)
```

### 📸 Rich Content Support

Now includes the `richContent` field for image notifications:

```python
message = PushMessage(
    to=token,
    title="Check this out!",
    body="Beautiful image notification",
    richContent={"image": "https://example.com/image.jpg"}
)
```

- [sync_example.py](examples/sync_example.py) - Synchronous usage
- [dependency_injection_example.py](examples/dependency_injection_example.py) - DI patterns

## Migration Guide

### From v2.1.x to v2.2.0

The library is **fully backward compatible**. Existing code will continue to work without changes:

```python
# Old code still works!
from exponent_server_sdk import PushClient, PushMessage

client = PushClient()
ticket = client.publish(PushMessage(to=token, body="Hello"))
```

### New Features You Can Adopt

1. **Use Pydantic models** - Your `PushMessage` objects now have validation
2. **Try async/await** - Use `AsyncPushClient` for better performance
3. **Add richContent** - Include images in your notifications
4. **Inject dependencies** - Pass custom HTTP clients for testing

## Type Hints

All classes and methods now include full type hints:

```python
from exponent_server_sdk import AsyncPushClient, PushMessage, PushTicket
from typing import List

async def send_many(messages: List[PushMessage]) -> List[PushTicket]:
    async with AsyncPushClient() as client:
        return await client.publish_multiple(messages)
```

### Comparison with Official SDK

| Feature | This SDK (`async-expo-push-notifications`) | [Official Community SDK](https://github.com/expo-community/expo-server-sdk-python) |
|---------|-------------------------------------------|----------------------------------------------------------------------------------|
| **Async/Await** | ✅ Full async support | ❌ Sync only |
| **Type Hints** | ✅ Complete type hints | ⚠️ Partial |
| **Pydantic** | ✅ Type-safe models | ❌ Named tuples |
| **Dependency Injection** | ✅ Supported | ❌ No |
| **Rich Content** | ✅ Image support | ❌ Not included |
| **Python Version** | 3.8+ | 3.6+ |
| **Backward Compatible** | ✅ Yes | - |

**When to use this SDK:**
- You need async/await support for high-performance applications
- You want type safety with Pydantic models
- You need dependency injection for testing
- You want modern Python features (type hints, async)

**When to use the official community SDK:**
- You need a battle-tested, widely-used solution
- You're using Python 3.6-3.7
- You prefer simpler, synchronous code
