You can store documents natively as JSON, instead of serializing them as strings:

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

This approach lets you 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 workflow saves effort and reduces errors. For example, decrementing a stock counter does not require reading, parsing, and rewriting the entire document in your application. Instead, it happens safely and immediately on the server.

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