  • key (required) – A Redis key of JSON document type.

  • path (optional) – A JSON path. Defaults to the root if not provided.

Return

If the path is enhanced syntax:

  • Array of strings that represent the type of value at each path. The type is one of {"null", "boolean", "string", "number", "integer", "object" and "array"}.

  • If a path does not exist, its corresponding return value is null.

  • Empty array if the document key does not exist.

If the path is restricted syntax:

  • String, type of the value

  • Null if the document key does not exist.

  • Null if the JSON path is invalid or does not exist.

Enhanced path syntax:

127.0.0.1:6379> JSON.SET k1 . '[1, 2.3, "foo", true, null, {}, []]' OK 127.0.0.1:6379> JSON.TYPE k1 $[*] 1) integer 2) number 3) string 4) boolean 5) null 6) object 7) array

Restricted path syntax:

127.0.0.1:6379> JSON.SET k1 . '{"firstName":"John","lastName":"Smith","age":27,"weight":135.25,"isAlive":true,"address":{"street":"21 2nd Street","city":"New York","state":"NY","zipcode":"10021-3100"},"phoneNumbers":[{"type":"home","number":"212 555-1234"},{"type":"office","number":"646 555-4567"}],"children":[],"spouse":null}' OK 127.0.0.1:6379> JSON.TYPE k1 object 127.0.0.1:6379> JSON.TYPE k1 .children array 127.0.0.1:6379> JSON.TYPE k1 .firstName string 127.0.0.1:6379> JSON.TYPE k1 .age integer 127.0.0.1:6379> JSON.TYPE k1 .weight number 127.0.0.1:6379> JSON.TYPE k1 .isAlive boolean 127.0.0.1:6379> JSON.TYPE k1 .spouse null
