Are concurrent queries via same endpoint possible using useLazyQueryHook in Redux Toolkit - redux

The problem: When doing multiple requests to the same endpoint, useLazyQueryHook will return a response only with the latest query with status set to 'fulfilled' and response data, while other requests made before are stuck with status 'pending' and without response data.
Desired functionality: The lazy query hook does not overwrite the previous returns (if overwrite is the case) but returns data from each query which can be accessed in a useEffect hook f.ex. Is this possibly not the correct approach for this use case when using RTK?
I have the following endpoint within createAPI...
getLoggerCheck: builder.query<any, any>({
query: ({ loggerId }) => ({
url: '/scan/check',
params: {
logger: loggerId,
}
}),
transformResponse(data: any) {
console.log(data); // <---- Correct data for each request is logged out here
return data;
}
})
... but when using the generated useLazyGetLoggerCheckQuery hook like so and making approx 5 requests / sec with runLoggerChecks({loggerId: XXXXX}) only the most recent query is returned with data and status 'fulfilled'.
const [runLoggerCheck, loggerCheckResponse] = useLazyGetLoggerCheckQuery();
useEffect(() => {
console.log(loggerCheckResponse)
}, [loggerCheckResponse]);

NextJS getting url parameters returns empty at the begining

I want to get URL parameters at the begining of page, but firstly it returns empty, after a while
const rout = useRouter()
useEffect(() => {
console.log('queries:')
console.log(rout.query)
}, [rout])
It returns {} for the first time, but after a render, It returns {'myparam': 'blabla'}
How can I get URL parameter without returning an empty result?
According to the docs, the useRouter hook from next/router returns a prop isReady, which you can check.
isReady: boolean - Whether the router fields are updated client-side
and ready for use. Should only be used inside of useEffect methods and
not for conditionally rendering on the server.
const rout = useRouter()
useEffect(() => {
if (rout.isReady) {
//rout.query will be ready here
}
}, [rout])

NuxtJS store returning local storage values as undefined

I have a nuxt application. One of the components in it's mounted lifecycle hook is requesting a value from the state store, this value is retrieved from local storage. The values exist in local storage however the store returns it as undefined. If I render the values in the ui with {{value}}
they show. So it appears that in the moment that the code runs, the value is undefined.
index.js (store):
export const state = () => ({
token: process.browser ? localStorage.getItem("token") : undefined,
user_id: process.browser ? localStorage.getItem("user_id") : undefined,
...
Component.vue
mounted hook:
I'm using UserSerivce.getFromStorage to get the value directly from localStorage as otherwise this code block won't run. It's a temporary thing to illustrate the problem.
async mounted() {
// check again with new code.
if (UserService.getFromStorage("token")) {
console.log("user service found a token but what about store?")
console.log(this.$store.state.token, this.$store.state.user_id);
const values = await ["token", "user_id"].map(key => {return UserService.getFromStorage(key)});
console.log({values});
SocketService.trackSession(this, socket, "connect")
}
}
BeforeMount hook:
isLoggedIn just checks that the "token" property is set in the store state.
return !!this.$store.state.token
beforeMount () {
if (this.isLoggedIn) {
// This runs sometimes??? 80% of the time.
console.log("IS THIS CLAUSE RUNNING?");
}
}

OP's app is quite big from what it looks, so finding the exact reason is kinda difficult.
Meanwhile, setting ssr: false fixed the errors.
It raised more, but they should probably be asked into another question nonetheless.

Watching for a redux-saga action in redux

All of my API calls are handled by redux-sagas. I'm creating a heartbeat modal in my app to detect inactivity. Each time a saga goes off I want to clear my setTimeout so I know that the user is active.
My middleware is a basic one at the moment:
const heartbeatMonitor => store => next => action {
if (action['##redux-saga/SAGA_ACTION']) {
clearTimeout(window.myTimeout);
}
window.myTimeout = window.setTimeout(function() {
// send off an action to tell user they are inactive
}, 100000);
}
It seems like looking for this symbol, ##redux-saga/SAGA_ACTION, is the only way to tell if the action is a saga. I see that redux-sagas has a createSagaMiddleware(options) and I tried using effectMiddlewares but it doesn't seem like you have access to the dispatch method in there so I can't send off a new actions.
but it doesn't seem like you have access to the dispatch method in there so I can't send off a new actions.
Not sure whether this is the kind of solution you wanted, but you do have access to the dispatch method where your comment // send off an action to tell user they are inactive is located in your code snippet, as it is exposed by the store object. (this is documented in the Store Methods Section of the store in the redux docs)
Therefore something like the following should satisfy your case:
const heartbeatMonitor => store => next => action {
if (action['##redux-saga/SAGA_ACTION']) {
clearTimeout(window.myTimeout);
}
const { dispatch } = store;
window.myTimeout = window.setTimeout(() => {
dispatch({ type: "USER_INACTIVE" });
}, 100000);
}
Note: I would probably implement this differently (using redux-sagas effects) Maybe this is an option for you too:
Example Saga
import { put, delay } from "redux-saga/effects";
function* inactiveSaga() {
yield delay(100000);
yield put({ type: "USER_INACTIVE" })
}
Example Integration of saga above:
(add the following in your root saga)
//import { takeLatest } from "redux-saga/effects";
takeLatest(() => true, inactiveSaga)
Explanation: Every action will trigger the inactiveSaga (cause () => true). The inactiveSaga will wait 100000ms before dispatching the "inactive action". If there is a new action within this waiting time the previous execution of the inactiveSaga will be canceled (cause takeLatest, see redux-saga effect docs for takeLatest) and started from the beginning again. (Therefore no "inactive action" will be sent and the inactiveSaga will start to wait for these 100000ms again, before being cancelled or completing the delay and dispatching the "inactive action")

How do I delete user analytics data from Firebase using userDeletionRequests:upsert?

Problem Description
My Android app collects data via Google Analytics for Firebase. For privacy reasons, users must be able to wipe their data off the Firebase servers, should they choose to do so.
The app requests a deletion by forwarding its Firebase APP_INSTANCE_ID to my own server. This server has been prepared in advance with credentials, from my personal Google account (via oauth2), for managing the Firebase project. The server authenticates with www.googleapis.com, and, using the supplied APP_INSTANCE_ID, invokes the upsert.
As noted by the documentation, the generic Google Analytics API is appropriate for this task.
After some initial trouble (b/c I didn't have the correct auth scope, and the Analytics API wasn't properly enabled), googleapis.com now returns HTTP 200 for each upsert request. (As an aside, even if you supply a bogus APP_INSTANCE_ID, it returns 200.)
Here is a sample response from the upsert, which shows nothing amiss:
{ kind: 'analytics#userDeletionRequest',
id:
{ type: 'APP_INSTANCE_ID',
userId: (REDACTED 32-char hexidecimal string) },
firebaseProjectId: (REDACTED),
deletionRequestTime: '2018-08-28T12:46:30.874Z' }
I know the firebaseProjectId is correct, because if I alter it, I get an error. I have verified that the APP_INSTANCE_ID is correct, and stable up until the moment it is reset with resetAnalyticsData().
Test Procedure
To test the deletions, I populated Firebase with several custom events, using the procedure below (Nexus 5X emulator, no Google Play, no Google accounts configured, but that shouldn't make any difference):
Install the app
Fire off some custom events (FirebaseAnalytics.logEvent)
Observe those events appear on the Firebase console
(About a minute later:) Make the upsert call, observe HTTP 200, and note the "deletionRequestTime"
Immediately call FirebaseAnalytics.resetAnalyticsData (to clear any event data cached on the device)
Uninstall the app
Rinse & repeat 7 or 8 times
However, even 24 hours later, 100% of the Firebase events are still present in the events table. No discernable state change has taken place on the Firebase server as a result of the upserts.
Question
So, what am I doing wrong? how do I successfully delete user data from Google Analytics for Firebase?
EDIT
Here's the code I'm using to make a request (from node.js):
const request = require( 'request' );
...
_deletePersonalData( data )
{
return new Promise( (resolve, reject) => {
request.post({
url: 'https://www.googleapis.com/analytics/v3/userDeletion/userDeletionRequests:upsert',
body: {
kind: 'analytics#userDeletionRequest',
id: {
type: 'APP_INSTANCE_ID',
userId: data.firebaseAppInstanceId
},
firebaseProjectId: (REDACTED)
},
headers: {
Authorization: 'Bearer ' + iap.getCurAccessToken()
},
json: true
}, (err, res, body) => {
console.log( 'user-deletion POST complete' );
console.log( 'Error ' + err );
console.log( 'Body ', body );
if( err )
{
reject( err );
return;
}
if( body.error )
{
reject( new Error( 'The Google service returned an error: ' + body.error.message + ' (' + body.error.code + ')' ) );
return;
}
resolve({ deletionRequestTime: body.deletionRequestTime });
});
});
}
Here's a sample request body:
{
kind: 'analytics#userDeletionRequest',
id: {
type: 'APP_INSTANCE_ID',
userId: (REDACTED 32-char hexidecimal string)
},
firebaseProjectId: (REDACTED)
}
And here's the console output for that same request (same userId and everything):
user-deletion POST complete
Error: null
Body: { kind: 'analytics#userDeletionRequest',
id:
{ type: 'APP_INSTANCE_ID',
userId: (REDACTED 32-char hexidecimal string) },
firebaseProjectId: (REDACTED),
deletionRequestTime: '2018-08-29T17:32:06.949Z' }
Firebase support just got back to me, and I quote:
Upsert method deletes any individual user data we have logged, but aggregate metrics are not recomputed. This means that you might not see any changes in the events tab in your Analytics console.
So, basically my mistake was expecting the events to disappear from the console.
This, of course, raises the question of how one determines that the API is actually working... but maybe the HTTP 200 is enough.

Managing API calls with default error handling in react-redux application

I've completed my application and I'm now integrating the real api calls for each async action. I use redux-thunk which returns a promise from an axios instance.
Currently I'm repeating so much of the same logic in my actions that I'm sure I'm missing something.
API response example
{
"ok": true,
"warnings": [],
"errors": [],
"response": {/* stuff */}
}
The Idea is that I need the same error handling if either the axios call fails (so another response status then 2xx). Additionally I need to also do the same thing when the api response returns "ok": false.
Preferably I would like to dispatch an action which shows a notification to users so they also know when something goes wrong. Aside from that I want to log the api response's warnings and error entities. This is mainly because I'll use sentry for monitoring.
Any Ideas on how to do this without doing a .catch() with the same logic on each api call in any of my action creators?
I've thought about using the onError of axios but that can't dispatch an action as far as I know.
You could use a response interceptor to dispatch appropriate actions. Just wire them up after you create the store
const store = createStore(...)
axios.interceptors.response.use((response) => {
if (!response.data.ok) {
store.dispatch({ type: "RESPONSE_NOT_OK", response }
}
return response
}, (error) => {
store.dispatch({ type: "RESPONSE_HAD_ERROR", error }
return Promise.reject(error)
})
Obviously, you can handle the response how ever you want, this was just for demonstration purposes.
