How to store list of dictionaries returned in Redis using NodeJS?

I am writing a NodeJS app that does a get request to a third party api. This api returns a list of dictionaries. I would like to take this result, and store it in my redis client. How do I do that?

The results object looks like this -

[{"foo":123, "bar":456}, {"foo":789, "bar":012}]

I would do it simple assuming your data as list or list as string,

      let redis = require("redis"),
      publisher = redis.createClient(option.redisPort, option.redisHost); 
      publisher.publish("id", DATA);  // here we publish the data.

Are you looking for something like this?

It sounds like you don't need to query elements from the dicts so it should be fine just storing them as json strings in a redis list. When you bulk add to the list you can stringify them, just make sure to use some form of pipe-lining so you're not making unneeded api calls. Then you can simply parse the json string dicts when you need them. ex:

function setList (list, callback) {
  const pipeline = redis.pipeline();
  for (const dict of list) {
    pipeline.rpush('myList', JSON.stringify(dict));
  }
  pipeline.exec(callback);
}

function popList (callback) {
  redis.lpop('mylist', function (error, data) {
    if (error) { return callback(error) }
    callback(null, JSON.parse(data));
  });
}
