Thanks @lukemorales! - ## Generate query options and add support for nested keys
New in @lukemorales/query-key-factory
is support for nested keys and generation of query options, adopting the query options overload as first class citizen, in preparation for React Query v5 roadmap.
const people = createQueryKeys('people', {
person: (id: number) => ({
queryKey: [id],
queryFn: () => api.getPerson({ params: { id } }),
contextQueries: {
ships: {
queryKey: null,
queryFn: () =>
api.getShipsByPerson({
params: { personId: id },
}),
},
film: (filmId: string) => ({
queryKey: [filmId],
queryFn: () =>
api.getFilm({
params: { id: filmId },
}),
}),
},
}),
});
Each entry outputs an object that can be used in the query options overload in React Query:
console.log(people.person('person_01'));
// => output:
// {
// queryKey: ['people', 'person', 'person_01'],
// queryFn: () => api.getPerson({ params: { id: 'person_01' } }),
// _ctx: { ...queries declared inside "contextQueries" }
// }
Then you can easily just use the object in useQuery
or spread it and add more query options to that observer:
export const Person = ({ id }) => {
const personQuery = useQuery(people.person(id));
return {
/* render person data */
};
};
export const Ships = ({ personId }) => {
const shipsQuery = useQuery({
...people.person(personId)._ctx.ships,
enabled: !!personId,
});
return {
/* render ships data */
};
};
export const Film = ({ id, personId }) => {
const filmQuery = useQuery(people.person(personId)._ctx.film(id));
return {
/* render film data */
};
};
All query key values should now be an array. Only the first level keys (those not dynamically generated) can still be declared as null
, but if you want to pass a value, you will need to make it an array.
export const todosKeys = createQueryKeys('todos', {
mine: null,
- all: 'all-todos',
+ all: ['all-todos'],
- list: (filters: TodoFilters) => ({ filters }),
+ list: (filters: TodoFilters) => [{ filters }],
- todo: (todoId: string) => todoId,
+ todo: (todoId: string) => [todoId],
});
You can still use objects to compose a query key, but now they must be inside an array because plain objects are now used for the declaration of the query options:
export const todosKeys = createQueryKeys('todos', {
- list: (filters: TodoFilters) => ({ filters }),
+ list: (filters: TodoFilters) => ({
+ queryKey: [{ filters }],
+ }),
});
With the new API, the output of an entry will always be an object according to what options you've declared in the factory (e.g.: if you returned an array or declared an object with only queryKey
, your output will be { queryKey: [...values] }
, if you also declared queryFn
it will be added to that object, and contextQueries
will be available inside _ctx
):
export const todosKeys = createQueryKeys('todos', {
todo: (todoId: string) => [todoId],
list: (filters: TodoFilters) => {
queryKey: [{ filters }],
queryFn: () => fetchTodosList(filters),
},
});
- useQuery(todosKeys.todo(todoId), fetchTodo);
+ useQuery(todosKeys.todo(todoId).queryKey, fetchTodo);
- useQuery(todosKeys.list(filters), fetchTodosList);
+ useQuery(todosKeys.list(filters).queryKey, todosKeys.list(filters).queryFn);
// even better refactor, preparing for React Query v5
+ useQuery({
+ ...todosKeys.todo(todoId),
+ queryFn: fetchTodo,
+ });
+ useQuery(todosKeys.list(filters));
The helper types to infer query keys in the created store reflect the new output, to account for all possible use cases:
type TodosKeys = inferQueryKeys<typeof todosKeys>;
- type SingleTodoQueryKey = TodosKeys['todo'];
+ type SingleTodoQueryKey = TodosKeys['todo']['queryKey'];

Thanks @lukemorales! - ## Remove deprecated methods
Since v0.6.0
, the default
key and and toScope
method have been deprecated from the package.
default
and toScope
removed from implementationdefault
key and toScope
method have been officially removed from the code, which means that if you try to access them, you will either receive undefined
or your code will throw for trying to invoke a function on toScope
that does not exist anymore.
