Getting started

Single Node client

import asyncio
from coredis import Redis

async def example():
    client = Redis(host='127.0.0.1', port=6379, db=0)
    await client.flushdb()
    await client.set('foo', 1)
    assert await client.exists(['foo']) == 1
    await client.incr('foo')
    await client.incrby('foo', increment=100)

    assert int(await client.get('foo')) == 102
    await client.expire('foo', 1)
    await asyncio.sleep(0.1)
    await client.ttl('foo')
    await asyncio.sleep(1)
    assert not await client.exists(['foo'])

asyncio.run(example())

Cluster client

 import asyncio
 from coredis import RedisCluster

 async def example():
     client = RedisCluster(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'

asyncio.run(example())
