chat-py-adapter-state-ioredis 0.1.0

ioredis-style (pipeline-oriented) Redis state adapter for chat-py

chat-adapter-state-ioredis

ioredis-flavoured Redis state adapter for chat-py. Python port of upstream packages/state-ioredis.

Why this package exists

In Node.js, upstream ships two separate state packages — @chat-sdk/state-redis (wraps the modern redis / node-redis client) and @chat-sdk/state-ioredis (wraps the legacy ioredis client). Python has no such split: redis.asyncio is the canonical async client. So this package is a thin subclass of RedisStateAdapter — behaviour is identical; the only difference is the lock-token prefix (ioredis_ vs redis_), which matches upstream byte-for-byte so a single Redis instance can host mixed Python / TypeScript clients that inspect the token prefix.

Install

uv add chat-py-adapter-state-ioredis

Minimal example

from chat import Chat
from chat_adapter_state_ioredis import create_ioredis_state
from chat_adapter_slack import create_slack_adapter

bot = Chat(
    user_name="mybot",
    adapters={"slack": create_slack_adapter()},
    state=create_ioredis_state(url="redis://localhost:6379"),
)

All other config (client injection, key prefix) is inherited from chat-adapter-state-redis — see that package's README.

Parity notes

• See chat-adapter-state-redis for the full implementation. The only override is acquire_lock, which emits ioredis_<ts>_<hex> tokens instead of redis_<ts>_<hex>.

Test

uv run pytest packages/chat-adapter-state-ioredis

# Live — shares REDIS_URL with state-redis
REDIS_URL=redis://localhost:6379 uv run pytest packages/chat-integration-tests -k ioredis
