[Module: server/TS]: Generic query pipelining
Hello, I am trying to build a custom react hook that contains a "pipeline" of Convex functions. The pipeline is simple: Query A returns an array of Id<Table>, and Query B accepts an array of Id<Table> and enriches them (basically performing joins with other tables):
I want to make this hook generic such that it can be used with any compatible getter/enrichment function pair, e.g. both
I found that specifying
I have attached screenshots of my code until now, the TS error, and usage in the front-end (which works).
I know this post may be confusing, and that it may not be clear what I am actually asking about or trying to achieve, and I apologize for that. I am a bit out of my depth TS-wise, but I hope someone understands what I'm trying to do and has some ideas! Thank you very much.
() => getDocumentIds --> (Ids) => enrichDocuments(Ids)I want to make this hook generic such that it can be used with any compatible getter/enrichment function pair, e.g. both
getVideoIds --> enrichVideos and getChannelIds --> enrichChannels. Therefore, the return type of Query A must be compatible with the parameter type of Query B. I have taken inspiration from the implementation of useQueryI found that specifying
Args in the FunctionReference of QueryB approximated the solution, but I had to manually specify the correct object key (e.g. "videoIds"). Is there a way to use some placeholder as such?: { PLACEHOLDER: FunctionReturnType<BaseQuery> }I have attached screenshots of my code until now, the TS error, and usage in the front-end (which works).

TL;DR
How can I write a generic custom hook which takes as parametersQueryA, QueryA['_args'] as well asQueryB in order to invoke in a generic way convex.query(query: QueryB, ...args: FunctionReturnType<QueryA> ? A simplifying concern is that I know as the "human" that any QueryB I want to pass to this hook will only have one argument of the same type as the return value of QueryA (an array of document Ids)
