documentation

usage

const redis = require('pico-redis');
redis.connect();

redis.set('test', {fancy : 6})
    .then(()=>redis.get('test'))
    .then((val)=>{
        console.log(val);
    });

const userScope = redis.scope('user');
await userScope.set('current', userId);

redis.set(key, val, [expiry])

Stores key-val pair in redis. Optional expiry in milliseconds. Converts the val into stringified JSON. Returns a promise.

redis.get(key)

Retrieves the val stored at key. val will be attempted to be JSON parsed. Returns a promise.

redis.del(key)

Removes the val stored at key. Returns a promise.

redis.connect([redis_url], [redis_opts])

Creates and connects to the redis instance. By default, uses the process.env.REDIS_URL if redis_url is not specified. This will also create a new redis client isolated to this scope, see redis.scope. You can review the redis_opts here.

redis.close()

Closes the connection. Returns a promise.

redis.clear()

Clears the entire redis instance of all entries. Returns a promise.

redis.keys([search])

Returns an array of all the keys. If search is provided will use that as a regex on the keys.

redis.scope([scope])

Returns an instance of the lib where all the accessors use a key that is prefixed with scope. Can have it's own redis client if .connect() is called on the returned scope.

redis.client()

Access to the redis client created by node-redis
