Forgot to mention two things.
To define this function, the redis-cli has to be used:
❯ redis-cli
127.0.0.1:6379> RG.FUNCTION LOAD "#!js name=lib\n
redis.register_function('foo', ()=>{return 1;});"
Another thing is that one has to have Redis installed and the RedisGears
module loaded. The easiest way to start is the README within the
repository:
