InferQuery, InferMutation, InferInfiniteQuery types

This types are needed to infer some other types from mutations\configs.

type MyData = InferMutation<typeof myMutation, "data">;
type MyVariables = InferMutation<typeof myMutation, "variables">;
type MyConfig = InferMutation<typeof myMutation, "config">;

QueryConfigFromFn, MutationConfigFromFn, InfiniteQueryConfigFromFn

This types are needed to create configuration types from your functions of your http client

const myApi = {
  createApple: (name: string): Promise<AppleDC> => ...
}

type Config = MutationConfigFromFn<typeof myApi.createApple>

using keyword

Query, InfiniteQuery, Mutation supports out-of-box using keyword.

In your project you need to install babel plugin @babel/plugin-proposal-explicit-resource-management to add this support.

How it looks:

import { createQuery } from "mobx-tanstack-query/preset";

class DataModel {
  async getData() {
    using query = createQuery(() => yourApi.getData(), { queryKey: ["data"] });
    await when(() => !query.isLoading);
    return query.data!;
  }
}

const dataModel = new DataModel();
const data = await dataModel.getData();
// after call getData() created Query
// will be destroyed
