JSON.STRAPPEND key [path] value
Available in: Redis Stack
Time complexity: O(1) when path is evaluated to a single value, O(N) when path is evaluated to multiple values, where N is the size of the key
Appends the json-string values to the string at path.
path defaults to root if not provided.
Return
[] if the matching JSON value is not an array.
Examples
