I have this apiSlice:
export const apiSlice = createApi({
baseQuery: fetchBaseQuery({
baseUrl: `${baseUrl}${apiBasePath}`,
prepareHeaders: prepHeaders,
}),
endpoints: (builder) => ({
getPersonById: builder.query({
query: (personId) => ({
url: `person/${personId}`,
}),
}),
}),
});
const prepHeaders = (headers, { getState }) => {
const { token } = getState().auth;
headers.set('X-Request-Id', uuidv4());
headers.set('X-Client-Id', 'xxx');
headers.set('X-Client-Version', '1.0.0');
headers.set('Content-Type', 'application/vnd.api+json');
headers.set('Accept', 'application/vnd.api+json');
headers.set('Authorization', `Bearer ${token}`);
return headers;
};
Which is being used in this component:
const PersonDetails = () => {
const { personId } = useParams();
const { data, error, isLoading, isFetching } =
useGetPersonByIdQuery(personId);
return (<div>...render logic removed...</div>)
}
On load of the ReactJS page, it triggers the apiSlice right away since the default landing page renders the PersonDetails component.
1.But the first call has missing headers:
2.Refetching it via the refetch function now contains the headers:
UPDATE #1: Just observed that the Unit Test works fine and has the headers; so its really just when the App is actually running in the browser when this weird behaviour is occurring, what could it be?
UPDATE #2: Looks like it might be related to MirageJS when its turned on to as to intercept calls and return mock data. I observed that if I turn it off on startup, the initial call to the actual API has the headers. So I guess the question is now why is MirageJS causing this issue?

I have come across a problem that I do not understand while trying to integrate redux toolkit and more specifically RTK Query into my project. All I want to do is fetch an object array from my backend using a query hook, pass this data into my component and alter some of the elements inside the data based on user actions.
I am copying the incoming array so as not to mutate the original.
I can replace entire objects in the array with 'blah' but if I try to alter a single value within one of the objects I get:
TypeError: Cannot assign to read only property 'title' of object '#<Object>'
This problem didn't arise when I was using fetch().
I have been stuck on this for days!!!
apiSlice
import { createApi, fetchBaseQuery } from '#reduxjs/toolkit/query/react';
export const apiSlice = createApi({
reducerPath: 'api',
baseQuery: fetchBaseQuery({ baseUrl: process.env.devUrl }),
tagTypes: ['categories'],
endpoints: (builder) => ({
getCategories: builder.query({
query: () => 'categories/includingJobs',
transformResponse: (response) => response.data.data,
providesTags: ['categories'],
}),
}),
});
export const { useGetCategoriesQuery} = apiSlice;
Component
import {
useGetCategoriesQuery,
} from '../features/api/apiSlice';
const Test = () => {
const {
data: categories,
isLoading,
isSuccess,
isError,
error,
} = useGetCategoriesQuery();
if (isSuccess) {
let categoriesCopy = JSON.parse(JSON.stringify(categories));
//This is the line that breaks everything. Why?
categoriesCopy[0].title = 'new title';
}
return <h1>Something rendered</h1>;
};
export default Test;
I have a RTK query that's not refreshing it's core content after a delete mutation. Could anyone explain why ? It's not clear to me where the problem lies as there is not refresh request made at any point.
The code looks fine and it's pretty much the same I use in another API that's working. And on this second API I pass the same data (a list of items) and it's refreshing fine after a delete ; here's the code:
:
import { createApi, fetchBaseQuery } from '#reduxjs/toolkit/query/react';
import { Auth, API, Storage } from 'aws-amplify';
// Define a service using a base URL and expected endpoints
export const researchApi = createApi({
reducerPath: 'researchApi',
tagTypes: ['Research'],
baseQuery: fetchBaseQuery({
baseUrl: process.env.NEXT_PUBLIC_API_RESEARCH,
prepareHeaders: async (headers, { getState }) => {
const token = (await Auth.currentSession()).getIdToken().getJwtToken();
headers.set('Authorization', `${token}`);
headers.set('Content-Type', 'application/json');
return headers;
}
}),
endpoints: (builder) => ({
getResearch: builder.query({
query: () => `research`,
providesTags: ['Research']
}),
getResults: builder.query({
query: (id) => `results?searchid=${id}`,
}),
addResearch: builder.mutation({
query(keywords) {
const data = {
keywords: keywords
}
return {
url: `research`,
method: 'POST',
body: data
}
},
invalidatesTags: ['Research']
}),
deleteResults: builder.mutation({
query(results) {
// send array
let sanitized;
sanitized = results.filter(item => item);
const data = {
items: sanitized
}
//console.log('data: ', data);
return {
url: `removeresult`,
method: 'DELETE',
body: data
}
},
invalidatesTags: ['Research']
}),
}),
})
// Export hooks for usage in functional components, which are
// auto-generated based on the defined endpoints
export const { useGetResearchQuery, useGetResultsQuery, useAddResearchMutation, useDeleteResultsMutation } = researchApi
I'm calling the query like this :
const router = useRouter()
const { kwd } = router.query
const { data, error, isError, isLoading } = useGetResultsQuery(kwd);
if(isLoading) {
return (
<>
<Spinner animation="border" size="sm" role="status" />{' '} Please wait while Loading...
</>
)
}
Any idea would be very helpful as I'm completely lost with this...
Ok so problem solved, I didn't add the correct parameters :
getResearch: builder.query({
query: () => research,
providesTags: ['Research']
}),
getResults: builder.query({
query: (id) => `results?searchid=${id}`,
providesTags: ['Research'] // ========> THAT WAS MISSING
}),
Try and also make sure you are returning the correct data from the mutation. Thanks.
Return the correct fields from the mutation. If the required the field, can be id is not returned from the mutation, then there will be no refresh.
I have 2 completely independent components without any parent-child relationship being displayed on a single page.
Component 1 : Makes an API call fetches some records and display it in a table having server side-pagination
Component 2 : Contains a form, when the user submits the form the data in the component 1 needs to be refetch-ed through the backend.
Since I am using fetchBaseQuery to query the data, I believe I need to invalidate the cache in order to make the API call in the component 1.
I tried refetch() to fulfil that requirement but got no luck. I also tried setting the cache timeout using keepUnusedDataFor that too didn't work. Also, tried to do something with the tags, but for that I will have to use mutation instead of query and I am not sure how mutation is useful as per my use case
Here's some of the code :
component1.tsx
let { data, error, isSuccess, isError, isFetching, refetch } = useGetQuery(request, { skip});
const records = data?.records;
React.useEffect(() => {
if (records) {
// set records within table
}
}, [records]);
useGetQuery.ts
const extendedApi = mainApi.injectEndpoints({
endpoints: (builder) => ({
getQuery: builder.query<response, request>({
query: (request?: request) => ({
url: "someURL",
body: request,
method: "POST",
}),
providesTags: ["Requests"],
}),
}),
overrideExisting: true,
});
export const { useGetQuery } = extendedApi;
component2.tsx
let [trigger, data] = useSubmitFormMutation();
const submitForm = (e) => {
e.preventDefault();
trigger(// Some Object);
}
React.useEffect(() => {
if (isSuccess) {
updateRefreshRecords(true); // setting the hook to true to make an API call in component 1
}
}, [isSuccess]);
useSubmitFormMutation.ts
const extendedApi = mainApi.injectEndpoints({
endpoints: (builder) => ({
submitForm: builder.mutation<response, request>({
query: (request?: request) => ({
url: "some_other_url",
body: request,
method: "POST",
}),
invalidatesTags: ["Requests"],
}),
}),
overrideExisting: false,
});
export const { useSubmitFormMutation } = extendedApi;
mainAPI.ts
export const dynamicBaseQuery: BaseQueryFn<string | FetchArgs, unknown, FetchBaseQueryError> = async (args, api, extraOptions) => {
const { mainApiUrl } = (api.getState() as RootState).settings.endpoints;
const rawBaseQuery = fetchBaseQuery({
baseUrl: mainApiUrl,
prepareHeaders: (headers, { getState }) => {
// Use getState to pull the jwtToken and pass it in the headers to the api endpoint.
const { jwtToken } = (getState() as RootState).auth;
headers.set("authorization", jwtToken);
return headers;
},
});
return rawBaseQuery(args, api, extraOptions);
};
export const mainApi = createApi({
reducerPath: "mainApi",
baseQuery: dynamicBaseQuery,
endpoints: () => ({}),
tagTypes: ["Requests"],
});
store.ts
export const store = configureStore({
reducer: {
// other reducers
[localApi.reducerPath]: localApi.reducer,
[mainApi.reducerPath]: mainApi.reducer,
},
middleware: (getDefaultMiddleware) =>
getDefaultMiddleware({
serializableCheck: false,
})
.concat(localApi.middleware)
.concat(mainApi.middleware),
});
Can you please help me how can I invalidate the cache as per my use case.
Any help would be highly appreciated
Thanks
You can just add invalidatesTags to your mutation and that should refresh the query:
const extendedApi = mainApi.injectEndpoints({
endpoints: (builder) => ({
submitForm: builder.mutation<response, request>({
query: (request?: request) => ({
url: "some_other_url",
body: request,
method: "POST",
}),
invalidatesTags: ["Requests"]
}),
}),
overrideExisting: false,
});
No need for manual refetching or keepUnusedDataFor.
If that doesn't work, double-check that you added the api's middleware to the middlewares in your configureStore
Simply change your submitForm endpoint to mutation type and invalidate "Requests" tag on this endpoint. This way you don't have to use updateRefreshRecords.
You can then remove below useEffect in Component1.tsx
React.useEffect(() => {
if (refreshRecords) {
refetch();
}
}, [refreshRecords]);
and also remove keepUnusedDataFor: 5, from getQuery endpoint
I am not sure how mutation is useful as per my use case
When form is submitted, you are either creating or updating some data on backend. So, mutation is the right type of endpoint here. Use query type endpoint when you want to fetch some data from backend.
I'm new in RTK Query and I'm struggling with a use case I have to implement.
Scenario:
I have to merge the results from two API calls: the first API call is a private API call while the second one is a public API call. I need to merge the responses from these two APIs and write the computed result into the RTK cache so the UI can update accordingly.
Problem:
I'seeing that as soon as the await queryFullfilled is invoked, RTK Query immediately write into its cache the response from that API call and then when I make my calculation and try to update the RTK cache with apiSlice.util.updateQueryData the cache will change again. That's means that the UI will render twice, the first time using a wrong value (an array of persons) and the second time with the correct value (the JSON composed by ids and entities).
Question:
Is there a way to have just 1 write into the RTK cache so I can have just the computed value I need ? Because what is happening is that for some instances I'm having into the cache an array while I need the {ids: [...], entities: {}} JSON.
import { createEntityAdapter } from '#reduxjs/toolkit';
import axios from 'axios';
export const personsAdapter = createEntityAdapter();
const permitsInitialState = personsAdapter.getInitialState();
export const apiSlice = myServiceApi.injectEndpoints({
endpoints: (builder) => ({
getPersons: builder.query({
query: () => ({ url: '/persons', method: 'get' }),
onQueryStarted: async (_, { dispatch, queryFulfilled }) => {
try {
// Resolving the private API call
const { data: persons } = await queryFulfilled;
// Just a random public API call
const { data: todos } = await axios('https://jsonplaceholder.typicode.com/todos');
const enhancedPersons = /** Here the logic that merge the todos and the persons */
const state = personsAdapter.setAll(permitsInitialState, enhancedPermits);
dispatch(
apiSlice.util.updateQueryData('getPersons', _, (draft) => {
Object.assign(draft, state);
})
);
} catch (e) {
console.error(e);
}
},
}),
}),
});
That is one of the use cases of queryFn: Performing multiple requests with a single query
import {
createApi,
fetchBaseQuery,
FetchBaseQueryError,
} from '#reduxjs/toolkit/query'
import { Post, User } from './types'
const api = createApi({
baseQuery: fetchBaseQuery({ baseUrl: '/ ' }),
endpoints: (build) => ({
getRandomUserPosts: build.query<Post, void>({
async queryFn(_arg, _queryApi, _extraOptions, fetchWithBQ) {
// get a random user
const randomResult = await fetchWithBQ('users/random')
if (randomResult.error) throw randomResult.error
const user = randomResult.data as User
const result = await fetchWithBQ(`user/${user.id}/posts`)
return result.data
? { data: result.data as Post }
: { error: result.error as FetchBaseQueryError }
},
}),
}),
})
I'm using RTK query and I want to overwrite the state with the result from my transform request. I get my overview of a todos array by calling the getTodosOverview Query. After that I call a updateTodos query and this gives me back a new array with todos. I want to overwrite the original array with these results. I'm using the function updateQueryData but it doesnt seem to work. What am I missing here?
export const todosApi = createApi({
reducerPath: 'todosApi',
baseQuery: fetchBaseQuery({ baseUrl: 'api/todos' }),
endpoints: (builder) => ({
getToDosOverview: builder.query<Array<ToDos>, string>({
query: () => `getOverview`,
transformResponse: (rawResult: { data: Array<ToDos> }) => rawResult.data,
keepUnusedDataFor: 0,
}),
updateTodos: builder.mutation<Array<ToDos>, string>({
query: (fileId) => ({
url: `updateTodos?fileId=${fileId}`,
method: 'POST',
}),
transformResponse: (rawResult: { data: Array<ToDos> }) => rawResult.data,
async onQueryStarted(uniqueIdentifier, { dispatch, queryFulfilled }) {
const { data }= await queryFulfilled;
// Update state with new data from response
const patchResult = dispatch(
todosApi.util.updateQueryData(
'getToDosOverview',
uniqueIdentifier,
() => {
return data;
}
)
);
},
}),
}),
});
Well, you're not returning anything new.
const patchResult = dispatch(
todosApi.util.updateQueryData(
'getToDosOverview',
uniqueIdentifier,
// here you are getting the old state as a variable called `ToDos`
(ToDos: Array<ToDos>) => {
// and here you return that old state without any change
return ToDos;
}
)
);
Also, you are doing that way before you have even received a response.
The response will be available after the line
await queryFulfilled;
so you probably want to do something like
const { data } = await queryFulfilled
and then use data as the new value.
Generally, it seems like you are copy-pasting from the "optimistic updates" example. Please look at the example of pessimistic updates instead.
Also, with your code you are using the wrong argument if you want to update useGetToDosOverviewQuery().
You are updating useGetToDosOverviewQuery(uniqueIdentifier) here.
You should probably call
todosApi.util.updateQueryData('getToDosOverview', undefined, ...)
