Conversation
Add the FT.ALIASLIST command to @redis/search. Given an index name, it returns all aliases currently associated with that index, making alias discovery a first-class read-only API instead of relying on FT.INFO. The command is read-only and keyless. The reply is an unordered collection of alias strings: RESP2 array, RESP3 set. An existing index with no aliases yields an empty collection. The client adds no validation and propagates server errors (SEARCH_INDEX_NOT_FOUND, NOPERM) unchanged. Available from RediSearch 8.10.0.

Add a rejection test asserting the SEARCH_INDEX_NOT_FOUND error prefix is propagated unchanged for a missing index, per the command's error contract. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
Gate the FT.ALIASLIST integration tests with minimumDockerVersion [8, 10] so pre-8.10 CI matrix tags skip instead of failing with 'unknown command'. Pipeline test setup via Promise.all to match the sibling alias-command specs, and drop the non-conventional 'Read-only'/version prose from the registry JSDoc.

This pull request adds the
FT.ALIASLISTcommand to@redis/search. Given an index name, it returns all aliases currently associated with that index — making alias discovery a first-class, read-only Query Engine API instead of relying on theFT.INFOworkaround. Available from RediSearch 8.10.0.The command sends the fixed wire shape
FT.ALIASLIST indexwith no optional arguments. It is read-only and keyless (theindexargument is a Query Engine identifier, not a Redis key), so it runs on replicas and executes on an arbitrary shard in cluster mode with no fanout. The reply is an unordered collection of alias name strings: RESP2 returns an array of bulk strings, RESP3 returns a set — both surfaced via the client's normal RESP handling. An existing index with no aliases yields an empty collection rather than an error.Behavior notes callers should be aware of: the server resolves the argument with no alias lookup, so passing an alias name (or a missing index) fails with
SEARCH_INDEX_NOT_FOUND Index not found: <name>; permission failures surface asNOPERM. The client adds no validation and propagates server errors unchanged. Result ordering is not part of the contract and must not be relied upon.🤖 Generated with Claude Code
Note
Low Risk
Additive read-only search client command with no auth or data-path changes; behavior is delegated to RediSearch 8.10+.
Overview
Adds
FT.ALIASLISTto@redis/searchso callers can list aliases for an index viaclient.ft.aliasList/ALIASLIST, instead of inferring them fromFT.INFO.The new command module emits
FT.ALIASLIST index, is marked read-only and not keyed, and types the reply as a RESP2 array or RESP3 set of alias strings. Integration tests cover argument encoding, empty vs populated alias lists (order-agnostic), andSEARCH_INDEX_NOT_FOUNDfor a missing index, gated on Redis 8.10+.Reviewed by Cursor Bugbot for commit b1dec94.
