Insert into pagination after create

[nahtnam]

Hello,

I'm currently evaluating URQL but I have previous experience with Apollo. One of the largest pain points is inserting into a paginated list when a new item is created. I see this post about that topic https://www.howtographql.com/react-urql/7-pagination-and-cache-updates/ but I had a question about the last code block. It seems like the variable is hardcoded but this seems impractical. Generally, this would be in a completely different file of the query so it wouldn't know what the variables are. If we change the query to fetch 20 items we would need to remember to update it here. I was wondering if it is possible to define something like keyFields which would tell urql cache which fields actually determine unique queries. So for example:

first: 10, skip: 0, sortBy: createdAt : We would mark sortBy as a keyField and then proceed to insert into the beginning of the array regardless of how many items are loaded or what the other variables are.

I am also facing this problem, inserting stuff into paginated lists. Maybe the best thing would be to trigger loading of another page after creation? I cannot do updateQuery since all the variables change all the time so I wouldn't know which query to update.

you can use the cache.inspectFields method for this. It allows you to inspect which fields the cache knows about which means that it'll help you identify which cache fields to update. https://formidable.com/open-source/urql/docs/graphcache/cache-updates/#updating-many-unknown-links

This is the same method by which our pagination resolvers (like relayPagination) determines which pages to merge.

Yes, I know about inspectFields but never knew it can be used for that purpose. I will give it a shot and write here if I make it or not :D
