Redis + Node.js - how do I retrieve the values

Question

I am using a Redis database with Node.js. Using client.hmset("jobs", "jobId_12345", JSON.stringify(jsonJob)) I store JSON stringified jobs.

Now I want to iterate over all jobs and retrieve both job id and stringified job.

I tried client.hkeys("jobs", function (err, replies) {} but that only retrieves the keys.

I tried client.hgetall("jobs", function (err, obj) {} but I don't know how to retrieve both key and value from obj.

Any help is greatly appreciated because I'm stuck.

This is how it works. id in the code below is the record id.

redisclient.hgetall(key, function (err, dbset) {

  // gather all records
  for (id in dbset) {
       ...
  }
});

Redis HGETALL is the right command (client.hgetall)

As you can also see in redis docs, HGETALL returns all fields and values of the hash stored for the requested key.

I am not 100% sure but client.hgetall should return a list with fields and values

[field1_name, field1_value, field2_name, field2_value ...]
