create arbitrary node.js streams to and from redis
example directory there are various streaming examples.
var Redis = require'redis-stream'client = 6379 localhost 0
Return an object that streams can be created from with the
database options --
port defaults to
Return a node.js api compatible stream that is readable, writeable, and can be piped. All calls to
write on this stream will be prepended with the optional arguments passed to
Create a streaming instance of rpop:
var rpop = clientstream'rpop'rpoppipeprocessstdoutrpopwrite'my-list-key'
Which you can then pipe redis keys to, and they resulting elements will be piped to stdout.
Return a stream that can be piped to to transform an
hgetall stream into valid json, with a little help from JSONStream we can turn this into a real object.
hgetall = clientstream'hgetall'hgetallpipeRedisparsehgetallpipeJSONStreamstringifyObjectpipeprocessstdouthgetallwrite'my-hash-key-1'
It's possible to interact directly with the command parser that transforms a stream into valid redis data stream
var Redis = require'../'redis = 6379 'localhost'stream = redisstreamstreampipeRedisesjoin'\r\n'pipeprocessstdout// interact with the redis network connection directly// using `Redis.parse`, which is used internallystreamrediswriteRedisparse 'info'streamrediswriteRedisparse 'lpush' 'mylist' 'val'streamend
npm install redis-stream
