How do I cancel a fetchMore?

[panigrah]

I have a <Query> component with a fetchMore. I need to cancel the fetchMore if it has been initiated when the Query is restarted in my component. How can I do this?

thanks

I have a query getting data by category (categoryId as a param in options.variables)

• each category can have many items so I need fetchMore for "infinit" scroll

Problem is when changing category while fetching more at the last category

• updateQuery at fetchMore parameters gives items for the last category (but I get next/changed categoryId at variables params)
• so I get items from next category but also mixed with items from last category (when the fetchMore resolves)

If I can stop/cancel the fetchMore request there will be just the items for the next categoryId

I don't think there is a way to cancel a fetchMore directly, but I think if you keep track of the canceled status, and just return the previous result, that would simulate it.

However, a fix for fetchMore receiving the wrong variables (#2499) may cause cancelling to be unnecessary. Even if you send a new query before the old fetchMore resolves, it shouldn't overwrite the new query. Really, that fetchMore data is/should be still "valid" and could be cached for future queries.
