JSON
JSON support for Redis
JSON command summary
(view reference, 26 commands)
The JSON capability of Redis Open Source provides JavaScript Object Notation (JSON) support for Redis. It lets you store, update, and retrieve JSON values in a Redis database, similar to any other Redis data type. Redis JSON also works seamlessly with Redis Search to let you index and query JSON documents.
Primary features
- Full support for the JSON standard
- A JSONPath syntax for selecting/updating elements inside documents (see JSONPath syntax)
- Documents stored as binary data in a tree structure, allowing fast access to sub-elements
- Typed atomic operations for all JSON value types
Use Redis with JSON
The first JSON command to try is JSON.SET, which sets a Redis key with a JSON value. JSON.SET accepts all JSON value types. This example creates a JSON string:
Foundational: Set and retrieve JSON values using JSON.SET and JSON.GET to store and access JSON documents
> JSON.SET bike $ '"Hyperion"'
OK
> JSON.GET bike $
"[\"Hyperion\"]"
> JSON.TYPE bike $

Note how the commands include the dollar sign character $. This is the path to the value in the JSON document (in this case it just means the root).

String operations: Manipulate JSON strings using JSON.STRLEN to get length and JSON.STRAPPEND to concatenate values

Beginning with Redis 8.8, the JSON data type supports the ability to force a particular type when storing floating point homogeneous arrays (FPHAs)using the FPHA BF16|FP16|FP32|FP64 option to the JSON.SET command. Here's an example:
> JSON.SET fp_array $ '[[1,2,3,4e3],[5,6.0,7,8]]' FPHA FP16
OK
> JSON.GET fp_array $
"[[[1.0,2.0,3.0,4000.0],[5.0,6.0,7.0,8.0]]]"
The JSON.DEL command deletes any JSON value you specify with the path parameter.
You can manipulate arrays with a dedicated subset of JSON commands:
Array manipulation: Use JSON.ARRAPPEND to add elements, JSON.ARRINSERT to insert at positions, JSON.ARRTRIM to keep ranges, and JSON.ARRPOP to remove elements
> JSON.SET riders $ []
OK
> JSON.ARRAPPEND riders $ '"Norem"'
1) (integer) 1
> JSON.GET riders $
"[[\"Norem\"]]"
> JSON.ARRINSERT riders $ 1 '"Prickett"' '"Royce"' '"Castilla"'
1) (integer) 4
> JSON.GET riders $
"[[\"Norem\",\"Prickett\",\"Royce\",\"Castilla\"]]"
> JSON.ARRTRIM riders $ 1 1
1) (integer) 1
> JSON.GET riders $
"[[\"Prickett\"]]"
> JSON.ARRPOP riders $
1) "\"Prickett\""
> JSON.ARRPOP riders $

JSON objects also have their own commands:
Object operations: Inspect JSON objects using JSON.OBJLEN to count fields and JSON.OBJKEYS to retrieve all keys

Format CLI output
The CLI has a raw output mode that lets you add formatting to the output from
JSON.GET to make
it more readable. To use this, run redis-cli with the --raw option
and include formatting keywords such as INDENT, NEWLINE, and SPACE
with JSON.GET:
$ redis-cli --raw
> JSON.GET obj INDENT "\t" NEWLINE "\n" SPACE " " $

Enable Redis JSON
The Redis JSON data type is part of Redis Open Source and it is also available in Redis Software and Redis Cloud. See Install Redis Open Source or Install Redis Software for full installation instructions.
Limitation
A JSON value passed to a command can have a depth of up to 128. If you pass to a command a JSON value that contains an object or an array with a nesting level of more than 128, the command returns an error.
