The straightforward way to do this is explained here
However i am having a hard time trying to trigger the unsubscribe within a onAuthStateChanged which is in a different vuex module
store/user.js
...
onAuthStateChanged({ commit, dispatch }, { authUser }) {
if (!authUser) {
commit('RESET_STORE')
this.$router.push('/')
return
}
commit('SET_AUTH_USER', { authUser })
dispatch('database/getUserItems', null, { root: true })
this.$router.push('/home')
}
...
store/database.js
...
getUserItems({ state, commit }, payload) {
const unsubscribe = this.$fireStore
.collection('useritems')
.where('owner', '==', this.state.user.authUser.uid)
.onSnapshot(
(querySnapshot) => {
querySnapshot.forEach(function(doc) {
// STUFF
},
(error) => {
console.log(error)
}
)
},
...
How do i reference unsubscribe() from the user.js module when the user logs out (authUser undefined)?
I think you can just save it in you Vuex state tree and call it from there.
state: {
//....
listenerUnsubscribe: null,
//....
},
mutations: {
//....
SET_LISTENER_UNSUBSCRIBE(state, val) {
state.listenerUnsubscribe = val;
},
RESET_STORE(state) {
state.listenerUnsubscribe()
}
//....
},
actions: {
//....
getUserItems({ state, commit }, payload) {
const unsubscribe = this.$fireStore
.collection('useritems')
.where('owner', '==', this.state.user.authUser.uid)
.onSnapshot((querySnapshot) => {
querySnapshot.forEach(function(doc) {
// STUFF
},
(error) => {
console.log(error)
}
);
commit('SET_LISTENER_UNSUBSCRIBE', unsubscribe);
},

I am new to RTK query and need only one WebSocket connection for my entire application as you can see below I implemented it like an example in GitHub.
I need to somehow send my payload to this WebSocket by subscribing to it.
and then whenever the message comes in I update the other injected Endpoints' cache.
import { ApiSlice } from 'api';
import { instrumentsAdapter } from './marketSlice';
const socket = new WebSocket(process.env.REACT_APP_SOCKET_BASE_URL);
const socketConnected = new Promise((resolve, reject) => {
// Connection opened
try {
socket.addEventListener('open', (event) => {
resolve(event);
});
} catch (err) {
console.log('err', err);
reject(err);
}
});
export const socketApi = ApiSlice.injectEndpoints({
endpoints: (builder) => ({
socketChannel: builder.mutation({
async queryFn(arg) {
await socketConnected;
const { type, topic } = arg;
const sendPayload = { type, path: topic };
socket.send(JSON.stringify(sendPayload));
return { data: { messages: [] } };
},
async onCacheEntryAdded(arg, { cacheDataLoaded, cacheEntryRemoved }) {
console.log('arg', arg);
await cacheDataLoaded;
// Listen for messages
socket.onmessage = (res) => {
const message = JSON.parse(res.data);
try {
// ApiSlice.util.updateQueryData('getInstrumentByRefId', arg, (draft) => {
// console.log('arg', arg);
// draft = { ...message.value, baseVolume: 3 };
// });
} catch (err) {
console.log('err', err);
}
};
await cacheEntryRemoved;
socket.close();
}
})
})
});
export const { useSocketChannelMutation } = socketApi;
after so much reading docs and researching I finally find this solution working but I do not know if this is a best practice or not.
Here is my not-empty ApiSlice.
/* eslint-disable import/prefer-default-export */
// Or from '#reduxjs/toolkit/query' if not using the auto-generated hooks
import { createApi } from '#reduxjs/toolkit/query/react';
import axiosBaseQuery from './axiosBaseQuery';
export const socket = new WebSocket(process.env.REACT_APP_SOCKET_BASE_URL);
const socketConnected = new Promise((resolve, reject) => {
try {
socket.addEventListener('open', (event) => {
resolve(event);
});
} catch (err) {
reject(err);
}
});
// initialize an empty api service that we'll inject endpoints into later as needed
export const ApiSlice = createApi({
reducerPath: 'api',
baseQuery: axiosBaseQuery(),
endpoints: (builder) => ({
subscribeSocket: builder.mutation({
async queryFn(arg) {
await socketConnected;
const sendPayload = { type: 'SUBSCRIBE', path: arg };
socket.send(JSON.stringify(sendPayload));
return { data: { messages: [] } };
}
}),
unsubscribeSocket: builder.mutation({
async queryFn(arg) {
await socketConnected;
const sendPayload = { type: 'UNSUBSCRIBE', path: arg };
socket.send(JSON.stringify(sendPayload));
return { data: { messages: [] } };
}
}),
channel: builder.mutation({
async queryFn(onMessage) {
await socketConnected;
socket.addEventListener('message', onMessage);
return { data: { messages: [] } };
}
})
})
});
export const { useUnsubscribeSocketMutation, useSubscribeSocketMutation, useChannelMutation } =
ApiSlice;
and this is my enhanced Api slice
import { createEntityAdapter } from '#reduxjs/toolkit';
import { ApiSlice } from 'api';
export const instrumentsAdapter = createEntityAdapter({
selectId: (item) => item?.state?.symbol
});
export const marketApi = ApiSlice.injectEndpoints({
overrideExisting: false,
endpoints: (builder) => ({
getMarketMap: builder.query({
query: (type) => ({
url: `/market/map?type=${type}`,
method: 'get'
})
}),
getInstruments: builder.query({
query: (type) => ({
url: `/market/instruments?type=${type}`,
method: 'get'
})
}),
getInstrumentByRefId: builder.query({
query: (refId) => ({
url: `/market/instruments/${refId}/summary`,
method: 'get'
}),
transformResponse: (res) => {
return instrumentsAdapter.addOne(instrumentsAdapter.getInitialState(), res);
},
async onCacheEntryAdded(
arg,
{ updateCachedData, cacheDataLoaded, cacheEntryRemoved, dispatch }
) {
await cacheDataLoaded;
const payload = `instruments.${arg}.summary`;
// subs to socket
dispatch(ApiSlice.endpoints.subscribeSocket.initiate(payload));
// Listen for messages
const onMessage = (res) => {
const message = JSON.parse(res.data);
try {
updateCachedData((draft) => {
instrumentsAdapter.setOne(draft, message.value);
});
} catch (err) {
// eslint-disable-next-line no-console
console.log('err', err);
}
};
dispatch(ApiSlice.endpoints.channel.initiate(onMessage));
await cacheEntryRemoved;
// unsubs to socket
dispatch(ApiSlice.endpoints.unsubscribeSocket.initiate(payload));
}
}),
getCandles: builder.query({
query: ({ refId, bucket, end, limit = 1 }) => ({
url: `/market/instruments/${refId}/candles?bucket=${bucket}&end=${end}&limit=${limit}`,
method: 'get'
})
})
})
});
export const {
useGetMarketMapQuery,
useGetInstrumentByRefIdQuery,
useGetInstrumentsQuery,
useGetCandlesQuery
} = marketApi;
and I try to dispatch my socket endpoints from ApiSlice inside of onCacheEntryAdded.
async onCacheEntryAdded(
arg,
{ updateCachedData, cacheDataLoaded, cacheEntryRemoved, dispatch }
) {
await cacheDataLoaded;
const payload = `instruments.${arg}.summary`;
// subs to socket
dispatch(ApiSlice.endpoints.subscribeSocket.initiate(payload));
// Listen for messages
const onMessage = (res) => {
const message = JSON.parse(res.data);
try {
updateCachedData((draft) => {
instrumentsAdapter.setOne(draft, message.value);
});
} catch (err) {
// eslint-disable-next-line no-console
console.log('err', err);
}
};
dispatch(ApiSlice.endpoints.channel.initiate(onMessage));
await cacheEntryRemoved;
// unsubs to socket
dispatch(ApiSlice.endpoints.unsubscribeSocket.initiate(payload));
}
}),
```
I need to call checkConnection before any other action so I thought of using axios interceptors:
axios.interceptors.request.use(
async config => {
await store.dispatch(checkConnection())
const { requestTime, hash } = intro(store.getState())
return {
...config,
headers: {
'Request-Time': requestTime,
'Api-Hash-Key': hash
}
}
}
)
intro is a reselect selector used to do some 'heavy' computing on serverTime (serverTime is the result of checkConnection)
checkConnection is a redux thunk action:
export const checkConnection = () => async (dispatch, _, {
Intro
}) => {
dispatch(introConnectionPending())
try {
const { data: { serverTime } } = await Intro.checkConnection()
dispatch(introConnectionSuccess(serverTime))
} catch ({ message }) {
dispatch(introConnectionFailure(message))
}
}
So, now every time I dispatch an action that calls for an API the checkConnection runs first.
The problem is when the reducer responsible for type that main action dispatched (not the checkConnection) gets called it doesn't even see the payload.
Here is an example of a action:
export const getData = () => async (dispatch, getState, {
API
}) => {
dispatch(dataPending())
const credentials = getUsernamePasswordCombo(getState())
try {
const { data } = await API.login(credentials)
dispatch(dataSuccess(data))
} catch ({ message }) {
dispatch(dataFailure())
}
}
and its reducer:
export default typeToReducer({
[SET_DATA]: {
PENDING: state => ({
...state,
isPending: true
})
},
SUCCESS: (state, { payload: { data } }) => ({
...state,
isPending: false,
...data
}),
FAILURE: state => ({
...state,
isPending: false,
isError: true
})
}, initialValue)
The reducer is totally wrong. It should be:
export default typeToReducer({
[SET_DATA]: {
PENDING: state => ({
...state,
isPending: true
}),
SUCCESS: (state, { payload: { data } }) => ({
...state,
isPending: false,
...data
}),
FAILURE: state => ({
...state,
isPending: false,
isError: true
})
}
}, initialValue)
Note the SUCCESS and FAILURE parts are now inside [SET_DATA]
I'm trying to implement Firebase Notification in my RN App. I followed this post
But when I run the code, I'm getting Hooks can only be called inside the body of a function component. There's my App.json file
export default class App extends Component {
state = {
isLoadingComplete: false,
};
render() {
return (
<SafeAreaView forceInset={{ bottom: 'never'}} style={styles.container}>
{Platform.OS === 'ios' && <StatusBar barStyle="default" />}
<Provider store={store}>
<AppNavigator/>
</Provider>
</SafeAreaView>
);
}
And functions to get the token, permissions and show alert with the remote notification. Are these functions in right place?
useEffect(() => {
this.checkPermission();
this.messageListener();
}, []);
checkPermission = async () => {
const enabled = await firebase.messaging().hasPermission();
if (enabled) {
this.getFcmToken();
} else {
this.requestPermission();
}
}
getFcmToken = async () => {
const fcmToken = await firebase.messaging().getToken();
if (fcmToken) {
console.log(fcmToken);
this.showAlert("Your Firebase Token is:", fcmToken);
} else {
this.showAlert("Failed", "No token received");
}
}
requestPermission = async () => {
try {
await firebase.messaging().requestPermission();
// User has authorised
} catch (error) {
// User has rejected permissions
}
}
messageListener = async () => {
this.notificationListener = firebase.notifications().onNotification((notification) => {
const { title, body } = notification;
this.showAlert(title, body);
});
this.notificationOpenedListener = firebase.notifications().onNotificationOpened((notificationOpen) => {
const { title, body } = notificationOpen.notification;
this.showAlert(title, body);
});
const notificationOpen = await firebase.notifications().getInitialNotification();
if (notificationOpen) {
const { title, body } = notificationOpen.notification;
this.showAlert(title, body);
}
this.messageListener = firebase.messaging().onMessage((message) => {
console.log(JSON.stringify(message));
});
}
showAlert = (title, message) => {
Alert.alert(
title,
message,
[
{text: "OK", onPress: () => console.log("OK Pressed")},
],
{cancelable: false},
);
}
}
I have no ideia what I'm missing. Maybe some function out of scope...But I can't figure out
I changed useEffect to componentDidMount() and It worked great
componentDidMount() {
this.checkPermission();
this.messageListener();
}
I want to call an action in created hook, wait until is done and in same hook to display the result. Is that possible?
I tried to put async / await in actions but doesn't help.
This is the action property with the async function in the store:
actions: {
async FETCH_USER({commit}) {
await firebase.firestore().collection('test').get().then(res => {
commit('FETCH_USER', res.docs[0].data())
})
}
}
created() {
this.FETCH_USER()
console.log(this.GET_USER)
},
methods: {
...mapActions([
'FETCH_USER'
]),
login() {
if(this.$refs.form.validate()) {
console.log('welcome')
}
}
},
computed: {
...mapGetters([
'GET_USER'
])
}
export default new Vuex.Store({
state: {
user: null
},
getters: {
GET_USER: state => state.user
},
mutations: {
FETCH_USER(state, user) {
state.user = user
}
},
actions: {
FETCH_USER({commit}) {
firebase.firestore().collection('test').get().then(res => {
commit('FETCH_USER', res.docs[0].data())
})
}
}
})
async/await version
async FETCH_USER({ commit }) {
const res = await firebase.firestore().collection('test').get()
const user = res.docs[0].data()
commit('FETCH_USER', user)
return user
}
async created() {
// The action returns the user out of convenience
const user = await this.FETCH_USER()
console.log(user)
// -- or --
// Access the user through the getter
await this.FETCH_USER()
console.log(this.GET_USER)
}
You need to await the action call because it is an async function.
Promise version
FETCH_USER({ commit }) {
return firebase.firestore().collection('test').get().then(res => {
const user = res.docs[0].data()
commit('FETCH_USER', user)
return user
})
}
created() {
this.FETCH_USER().then(user => {
console.log(user)
})
// -- or --
this.FETCH_USER().then(() => {
console.log(this.GET_USER)
})
}
I have the following controller action
[HttpPost]
[Route("api/Tenant/SetTenantActive")]
public async Task<IHttpActionResult> SetTenantActive(string tenantid)
{
var tenantStore = CosmosStoreFactory.CreateForEntity<Tenant>();
var allTenants = await tenantStore.Query().Where(x => x.TenantDomainUrl != null).ToListAsync();
foreach(Tenant ten in allTenants)
{
ten.Active = false;
await tenantStore.UpdateAsync(ten);
}
var tenant = await tenantStore.Query().FirstOrDefaultAsync(x => x.Id == tenantid);
if (tenant == null)
{
return NotFound();
}
tenant.Active = true;
var result = await tenantStore.UpdateAsync(tenant);
return Ok(result);
}
And my react code:
import React, { Component } from 'react';
import { Table, Radio} from 'antd';
import { adalApiFetch } from '../../adalConfig';
import Notification from '../../components/notification';
class ListTenants extends Component {
constructor(props) {
super(props);
this.state = {
data: []
};
}
fetchData = () => {
adalApiFetch(fetch, "/Tenant", {})
.then(response => response.json())
.then(responseJson => {
if (!this.isCancelled) {
const results= responseJson.map(row => ({
key: row.ClientId,
ClientId: row.ClientId,
ClientSecret: row.ClientSecret,
Id: row.Id,
SiteCollectionTestUrl: row.SiteCollectionTestUrl,
TenantDomainUrl: row.TenantDomainUrl
}))
this.setState({ data: results });
}
})
.catch(error => {
console.error(error);
});
};
componentDidMount(){
this.fetchData();
}
render() {
const columns = [
{
title: 'Client Id',
dataIndex: 'ClientId',
key: 'ClientId'
},
{
title: 'Site Collection TestUrl',
dataIndex: 'SiteCollectionTestUrl',
key: 'SiteCollectionTestUrl',
},
{
title: 'Tenant DomainUrl',
dataIndex: 'TenantDomainUrl',
key: 'TenantDomainUrl',
}
];
// rowSelection object indicates the need for row selection
const rowSelection = {
onChange: (selectedRowKeys, selectedRows) => {
if(selectedRows[0].key != undefined){
console.log(selectedRows[0].key);
const options = {
method: 'post',
body: {tenantid:selectedRows[0].key},
};
adalApiFetch(fetch, "/Tenant/SetTenantActive", options)
.then(response =>{
if(response.status === 200){
Notification(
'success',
'Tenant created',
''
);
}else{
throw "error";
}
})
.catch(error => {
Notification(
'error',
'Tenant not created',
error
);
console.error(error);
});
}
},
getCheckboxProps: record => ({
type: Radio
}),
};
return (
<Table rowSelection={rowSelection} columns={columns} dataSource={this.state.data} />
);
}
}
export default ListTenants;
focus only on the onchange event,
And the screenshot:
And it looks like the request gets to the webapi (I attached the debugger)
Update:
Basically If I dont put FromBody I need to send the parameter via querystring.
However if I put from Body and I send the parameter in the body, its received null on the webapi
Add [FromBody] before your input parameter in your action method like this:
public async Task<IHttpActionResult> SetTenantActive([FromBody] string tenantid)
Then, convert your selected row key into string
const options = {
method: 'post',
body: { tenantid : selectedRows[0].key.toString() }
};
