Cancel request using redux observable is not working
I'm trying to add in canceling in my request using redux-observable. Trying to implement a simple login example. Currently, I am unable to submit the login request again after I added the cancelation.
const loginUserApiCall = (username, password) => {
return new Promise((resolve, reject) => {
if (username === "foo" && password === "foo") {
resolve({
user: { name: "foo", lastName: "fooLName", email: "foo@gmail.com" }
});
}
reject({ err: "Creds are incorrect" });
});
};
const loginRequestEpic = (action$, state$) =>
action$.pipe(
ofType(LOGIN_REQUEST),
mergeMap(action => {
const { username, password } = action.payload;
return loginUserApiCall(username, password);
}),
mergeMap(res => of(loginSuccess(res))),
takeUntil(action$.pipe(ofType(LOGIN_CANCELLED))),
catchError(err => {
return of(loginFailure(err))
})
);
What am I doing wrong as cancelation is not happening and I can't retry a request after canceling it? Once user cancels I should be able to retry again.

use switchMap, so that the previous request will be cancelled automatically when a second LOGIN_REQUEST action is fired.

Once takeUntil
is executed it'll complete your observable, so is when there are error thrown and the whole stream is deactivated. You can add repeat
operator to the end
action$.pipe(
ofType(LOGIN_REQUEST),
mergeMap(action => {
const { username, password } = action.payload;
return loginUserApiCall(username, password);
}),
mergeMap(res => of(loginSuccess(res))),
takeUntil(action$.pipe(ofType(LOGIN_CANCELLED))),
catchError(err => {
return of(loginFailure(err))
}),
repeat()
);
