fire request in a conditional statement

[Xi-gofore]

I am not sure is it my misunderstanding or not, but in general if I want to fire a request when certain condition is met, how can I do it? My impression of react-query seems like only support fire request when component is loaded.

In my case I only want to fire request to backend if condition is met:

const fireReqOnlyIfConditionMet = async ({myData}) => {
     if(myData.length>10) {
       // how can I fire request here ? Say it is a POST request, I need to use useMutation()
     }
}

you are talking about useMutation, right? This returns a mutate function, so the idea is to unconditionally call useMutation, this doesn't trigger a request. it gives you a mutate function, and once you invoke this function (can be in a condition), the mutation is started.

Thanks for clarifying. I misunderstood it.
