sanic-redis

Async Redis support for Sanic.

Built on top of Async version of Redis library.

HiRedis is available as an optional parser for higher throughput.

Installation

You can install this package as usual with pip:

pip install sanic-redis

Install the optional hiredis parser for higher throughput:

pip install "sanic-redis[hiredis]"

Requires Python 3.10+, Sanic 25.3+, and redis-py 7 or 8.

Config

Redis URLs are passed to redis.asyncio.from_url. See the redis-py URL documentation for supported schemes and query options:

https://redis.readthedocs.io/en/stable/connections.html#redis.asyncio.client.Redis.from_url

Basic setup:

app.config.REDIS = "redis://localhost:6379/0"
redis = SanicRedis()
redis.init_app(app)

Use ctx_name when the Sanic config key and runtime context name should differ:

app.config.REDIS_CACHE = "redis://localhost:6379/1"
redis = SanicRedis(config_name="REDIS_CACHE", ctx_name="cache")
redis.init_app(app)

Pass redis-py client options with from_url_kwargs:

redis = SanicRedis(from_url_kwargs={"decode_responses": True})
redis.init_app(app)

Use single_connection_client and auto_close_connection_pool as SanicRedis parameters, not inside from_url_kwargs or Redis URL query options.

Enable startup validation when the app should fail fast on Redis connection errors:

redis = SanicRedis(ping_on_startup=True)
redis.init_app(app)

Example

from sanic import Sanic
from sanic.response import text
from sanic_redis import SanicRedis

app = Sanic(__name__)

app.config.update(
    {
        'REDIS': "redis://localhost:6379/0",
        'REDIS1': "redis://localhost:6379/1",
        'REDIS2': "redis://localhost:6379/2",
    }
)

redis = SanicRedis() # default config_name is "REDIS"
redis.init_app(app)

redis1 = SanicRedis(config_name="REDIS1", ctx_name="redis1")
redis1.init_app(app)

redis2 = SanicRedis(config_name="REDIS2", ctx_name="redis2")
redis2.init_app(app)


@app.route('/test1')
async def test1(request):
    r = request.app.ctx.redis1
    await r.set("key1", "value1")
    result = await r.get("key1")
    return text(str(result))


@app.route('/test2')
async def test2(request):
    r = request.app.ctx.redis
    await r.set('key2', 'value2')
    result = await r.get('key2')
    return text(str(result))


@app.route('/test3')
async def test3(request):
    r = request.app.ctx.redis2
    await r.set('key3', 'value3')
    result = await r.get('key3')
    return text(str(result))


if __name__ == '__main__':
    app.run(debug=True)

Use request.app.ctx.<name> as the runtime connection source. SanicRedis.conn and SanicRedis.app were removed in 0.7.

Testing

pip install -e ".[test]"
docker compose -f docker-compose.test.yml up -d
tox -e py313-deps-latest
docker compose -f docker-compose.test.yml down

Run the quick compatibility smoke test with:

tox -e py313-deps-latest -- -m compat
