aioapns - An efficient APNs Client Library for Python/asyncio

**aioapns** is a library designed specifically for sending push-notifications to iOS devices
via Apple Push Notification Service. aioapns provides an efficient client through
asynchronous HTTP2 protocol for use with Python's ``asyncio``
framework.
aioapns requires Python 3.8 or later.
Performance
-----------
In my testing aioapns allows you to send on average 1.3k notifications per second on a single core.
Features
--------
* Internal connection pool which adapts to the current load
* Support for certificate and token based connections
* Ability to set TTL (time to live) for notifications
* Ability to set priority for notifications
* Ability to set collapse-key for notifications
* Ability to use production or development APNs server
* Support for basic HTTP-Proxies
Installation
------------
Use pip to install::
$ pip install aioapns
Basic Usage
-----------
.. code-block:: python
import asyncio
from uuid import uuid4
from aioapns import APNs, NotificationRequest, PushType
async def run():
apns_cert_client = APNs(
client_cert='/path/to/apns-cert.pem',
use_sandbox=False,
)
with read('/path/to/apns-key.p8') as key:
apns_key_client = APNs(
key=key,
key_id='<KEY_ID>',
team_id='<TEAM_ID>',
topic='<APNS_TOPIC>', # Bundle ID
use_sandbox=False,
)
request = NotificationRequest(
device_token='<DEVICE_TOKEN>',
message = {
"aps": {
"alert": "Hello from APNs",
"badge": "1",
}
},
notification_id=str(uuid4()), # optional
time_to_live=3, # optional
push_type=PushType.ALERT, # optional
)
await apns_cert_client.send_notification(request)
await apns_key_client.send_notification(request)
loop = asyncio.get_event_loop()
loop.run_until_complete(run())
