Instead of serialising your documents as strings, you can store them natively in JSON format:

JSON.SET product:1 $ '{"name":"Espresso machine","brand":"Bianca","price":459,"tags":["coffee","kitchen"],"stock":12}'

This method allows you to read or update individual fields atomically and server-side:

JSON.GET product:1 $.price
# "[459]"

JSON.NUMINCRBY product:1 $.stock -1
# "[11]"

JSON.ARRAPPEND product:1 $.tags '"gift"'

This approach simplifies your workflows and reduces errors. For example, decrementing a stock counter does not require reading, parsing, and rewriting the entire document in your application. The operation is performed instantly and safely on the server side.

You can find the full list of commands in the Redis JSON documentation.
