I have an array of Objects that I want to store in Redis. I can break up the array part and store them as objects but I am not getting how I can get somethings like

Answer 1

The thing I found working was storing the key as a unique identifier and stringifying the whole object while storing the data and applying JSON.parse while extracting it.

Example code:

client
    .setAsync(obj.deviceId.toString(), JSON.stringify(obj))
    .then((doc) => {
        return client.getAsync(obj.deviceId.toString());
    })
    .then((doc) => {
        return JSON.parse(doc);
    }).catch((err) => {
        return err;
    });

Though stringifying and then parsing it back is a computationally heavy operation and will block the Node.js server if the size of JSON becomes large. I am probably ready to take a hit for lesser complexity because I know my JSON wouldn't be huge, but that needs to be kept in mind while going for this approach.
