- Usage
JSON.ARRAPPEND key path json ...- Complexity
- O(N) where N is the number of values
- Module
- valkey-json
- Since module version
- 1.0.0
- ACL Categories
- @json, @write, @fast
Append one or more values to the array values at the path.
Examples
Enhanced path syntax:
127.0.0.1:6379> JSON.SET k1 . '[[], ["a"], ["a", "b"]]'
OK
127.0.0.1:6379> JSON.ARRAPPEND k1 $[*] '"c"'
1) (integer) 1
2) (integer) 2
3) (integer) 3
127.0.0.1:6379> JSON.GET k1
"[[\"c\"],[\"a\",\"c\"],[\"a\",\"b\",\"c\"]]"
Restricted path syntax:
127.0.0.1:6379> JSON.SET k1 . '[[], ["a"], ["a", "b"]]'
OK
127.0.0.1:6379> JSON.ARRAPPEND k1 [-1] '"c"'
(integer) 3
127.0.0.1:6379> JSON.GET k1
"[[],[\"a\"],[\"a\",\"b\",\"c\"]]"

RESP2
- If the path is enhanced syntax:
- Array reply: Array of integers representing the new length of the array at each path.
- Nil reply: For each path where the value is not an array.
- If the path is restricted syntax:
- Integer reply: The array's new length.
- Integer reply: If multiple array values are selected, the command returns the new length of the last updated array.
- Simple error reply:
- if the path does not exist.
- if the value at the path is not an array (only for restricted syntax).
