JSON.ARRINSERT to insert one or more values into the arrays a path selects, before a given index.
Elements at and after that index shift to the right, keeping the rest of the array in order. A negative index counts from the end of the array and an index equal to the array’s length appends, while an index outside the array returns an error. The reply is the new length of each array the path matched.
Syntax
Arguments
Important points
- Raw TCP examples pass JSON values as valid JSON text. Typed Upstash SDK helpers serialize native objects and values for you.
- Paths beginning with
$use JSONPath and can match multiple values, so many JSON commands return an array of per-match results.
Response
The reply reports the result of the operation. Error replies have the same shape in RESP2 and RESP3 and are surfaced as exceptions by the SDKs below.Client libraries often decode bulk strings, maps, sets, and numeric strings into language-native values. The table describes the Redis wire reply.
Examples
TCP examples use the TLSREDIS_URL from the Upstash console. REST examples use UPSTASH_REDIS_REST_URL and UPSTASH_REDIS_REST_TOKEN.
