npm i @zaeny/redis

Usage

parsing json data automaticly, both input json and output json

process.env.REDIS_URL="redis://redisuser:redispass@127.0.0.1:6379"

var client = createRedis(process.env.REDIS_URL);
connectRedis(client)

  
command(['ping'], client).then(console.log)
command(['json.get', 'foo', '$.data'], client)
command(['json.set', 'foo', '$', {data: 1}], client)
command(['json.mget', 'foo', 'bar', '$'], client)

blocking read and stream reading

reader(['xreadgroup', 'mystream', 'group1', 'consumer1', '100', '0', '0'], (data)=> console.log(data), rs);
reader(['xread', 'mystream', '100', '0', '0'], (data)=> console.log(data), rs);

command(['xadd', 'mystream', {data: '1'}], rs)
command(['xadd', 'mystream', ['data', '1']], rs);  

closing stream

var mystream = reader(['xread', 'mystream', '100', '0', '0'], (data)=> console.log(data), rs);
mystream.close();

add acknowledge

// ack([streamId]);
var processStream = ((data, ack) =>{
  ack(map(first, data));
  console.log(data);
}                     
reader(['xreadgroup', 'mystream', 'group1', 'consumer1', '100', '0', '0'], processStream, rs);

var mystream = reader(['xread', 'mystream', '100', '0', '0'], (data)=> console.log(data), rs);
