or from source:

$ python setup.py install

Getting started

More examples

Tip: since python 3.8 you can use asyncio REPL:

$ python -m asyncio

single node client

import asyncio
from aredis import StrictRedis

async def example():
    client = StrictRedis(host='127.0.0.1', port=6379, db=0)
    await client.flushdb()
    await client.set('foo', 1)
    assert await client.exists('foo') is True
    await client.incr('foo', 100)

    assert int(await client.get('foo')) == 101
    await client.expire('foo', 1)
    await asyncio.sleep(0.1)
    await client.ttl('foo')
    await asyncio.sleep(1)
    assert not await client.exists('foo')

loop = asyncio.get_event_loop()
loop.run_until_complete(example())

cluster client

 import asyncio
 from aredis import StrictRedisCluster

 async def example():
     client = StrictRedisCluster(host='172.17.0.2', port=7001)
     await client.flushdb()
     await client.set('foo', 1)
     await client.lpush('a', 1)
     print(await client.cluster_slots())

     await client.rpoplpush('a', 'b')
     assert await client.rpop('b') == b'1'

loop = asyncio.get_event_loop()
loop.run_until_complete(example())
