:bulb: Major update in v4.0 <

The returned response objects are instances of StreamResponse class. It inherits from dict, so it's fully backward compatible. Additionally, it provides other benefits such as rate limit information (resp.rate_limit()), response headers (resp.headers()) or status code (resp.status_code()).

📝 About Stream

You can sign up for a Stream account at our Get Started page.

You can use this library to access chat API endpoints server-side.

For the client-side integrations (web and mobile) have a look at the JavaScript, iOS and Android SDK libraries (docs).

⚙️ Installation

$ pip install stream-chat

✨ Getting started

:bulb: The library is almost 100% typed. Feel free to enable mypy for our library. We will introduce more improvements in the future in this area.

from stream_chat import StreamChat

chat = StreamChat(api_key="STREAM_KEY", api_secret="STREAM_SECRET")

# add a user
chat.upsert_user({"id": "chuck", "name": "Chuck"})

# create a channel about kung-fu
channel = chat.channel("messaging", "kung-fu")
channel.create("chuck")

# add a first message to the channel
channel.send_message({"text": "AMA about kung-fu"}, "chuck")

# we also expose some response metadata through a custom dictionary
resp = chat.deactivate_user("bruce_lee")

print(type(resp)) # <class 'stream_chat.types.stream_response.StreamResponse'>
print(resp["user"]["id"]) # bruce_lee

rate_limit = resp.rate_limit()
print(f"{rate_limit.limit} / {rate_limit.remaining} / {rate_limit.reset}") # 60 / 59 /2022-01-06 12:35:00+00:00

headers = resp.headers()
print(headers) # { 'Content-Encoding': 'gzip', 'Content-Length': '33', ... }

status_code = resp.status_code()
print(status_code) # 200

Async

import asyncio
from stream_chat import StreamChatAsync


async def main():
    async with StreamChatAsync(api_key="STREAM_KEY", api_secret="STREAM_SECRET") as chat:
        # add a user
        await chat.upsert_user({"id": "chuck", "name": "Chuck"})

        # create a channel about kung-fu
        channel = chat.channel("messaging", "kung-fu")
        await channel.create("chuck")

        # add a first message to the channel
        await channel.send_message({"text": "AMA about kung-fu"}, "chuck")

        # we also expose some response metadata through a custom dictionary
        resp = await chat.deactivate_user("bruce_lee")
        print(type(resp)) # <class 'stream_chat.types.stream_response.StreamResponse'>
        print(resp["user"]["id"]) # bruce_lee

        rate_limit = resp.rate_limit()
        print(f"{rate_limit.limit} / {rate_limit.remaining} / {rate_limit.reset}") # 60 / 59 / 2022-01-06 12:35:00+00:00

        headers = resp.headers()
        print(headers) # { 'Content-Encoding': 'gzip', 'Content-Length': '33', ... }

        status_code = resp.status_code()
        print(status_code) # 200


if __name__ == '__main__':
    loop = asyncio.get_event_loop()
    try:
        loop.run_until_complete(main())
    finally:
        loop.run_until_complete(loop.shutdown_asyncgens())
        loop.close()
