App animates/flows perfectly when using no conditional rendering, but as you can see in the gif it animates 2-3 times when logging out and logging back in to the app.

Problems I’ve noticed:

  • animation occurs 2-3 times
  • ‘/dashboard/statistics’ route display full black

Solutions I’ve tried:

  • conditional rendering the routes
  • confirmed the <IonPage> and <IonContent> tags on all the pages.

Code for Navigation:

    <IonApp>
      <IonReactRouter>
        <IonSplitPane contentId="main">
          <Menu />
          <IonRouterOutlet id="main">
            <Route exact path="/">
              <IntroductionPage />
            </Route>
            <Route exact path="/login">
              <Login />
            </Route>
            <Route exact path="/dashboard/statistics">
              {loginInfo.isLoggedIn ? <Statistics /> : <Redirect to="/login" />}
            </Route>
            <Route exact path="/dashboard/earnings">
              {loginInfo.isLoggedIn ? <Earnings /> : <Redirect to="/login" />}
            </Route>
            <Route exact path="/dashboard/about">
              {loginInfo.isLoggedIn ? <AboutForm /> : <Redirect to="/login" />}
            </Route>
            <Route exact path="/dashboard/settings">
              {loginInfo.isLoggedIn ? <Settings /> : <Redirect to="/login" />}
            </Route>
            <Route exact path="/dashboard/connect">
              {loginInfo.isLoggedIn ? <AccountConnect /> : <Redirect to="/login" />}
            </Route>
          </IonRouterOutlet>
        </IonSplitPane>
      </IonReactRouter>
    </IonApp>

Hmm, can’t really guess from just this. Can you provide an actual code example?
As well as your package versions for react router?

The code for the project: https://github.com/Niravpatel129/Ionic-project/blob/84614485b80c584ae8dcf84833673f8f9bdc9ce7/src/App.tsx

Version for the React Router: “^5.0.7”,

So the only thing that stands out is the order of operations in the logins.

For example:

  const handleDemoLogin = async () => {
    setLoading(true)
    try {
      setLoading(false)
      history.push('/dashboard/statistics')
      await loginContext.handleLogin({
        username: 'Demo',
        avatar: '',
        email: 'Demo@email.com',
        accessToken: '123',
        authStrategy: 'demo',
      })
    } catch (error) {
      setLoading(false)
      alert(error)
    }
  }

This triggers a navigation, but then also toggles some state change on the component, which could cause some issues. I changed the order so that the navigation happens at the very end of the order of operations.

  const handleDemoLogin = async () => {
    setLoading(true)
    try {
      setLoading(false)
      await loginContext.handleLogin({
        username: 'Demo',
        avatar: '',
        email: 'Demo@email.com',
        accessToken: '123',
        authStrategy: 'demo',
      })
      history.push('/dashboard/statistics')
    } catch (error) {
      setLoading(false)
      alert(error)
    }
  }

And could not replicate.

Thank you very much, the solution works great!

Hey Mike, one more thing the app seems to freak out again and go back into problems with navigation when prompted with a scenrio of freshing while logged in and logging out currently the logout logic is like this:

 onClick={() => {
              loginContextData.handleLogout()
              history.replace('/')
            }}

would the way the login / logout is handled in the context the right way to do it paired with ionic?

Bug:

  • instead of moving forward after the post login screen, it returns to the login page (not sure why) and only occures when refreshing on the /dashboard/statistics route and logging out and relogging in.
