            How can I redirect a user to login when a certain link is clicked using JWT
            Asked 2022-Apr-08 at 08:49

            I am trying to make it so that when a user clicks on a certain Link (Upload Component), it will redirect them to to the login component and am not sure how to accomplish this task in React. I was directed to another answered question, but it hasn't helped me as I am still confused on what I need to do with my own set up. I understand I need to make my own protected route (maybe), but I saw others accessing useContext and I do not have any file with context. I am using Version 6 in react dom. I am also using React router and redux in my project so I know I need to access the state somehow, just not sure how to wrap my mind around it so if anyone could help, I would appreciate it. The user is being stored in local storage with JWT authentication.




            Answered 2022-Apr-08 at 08:49

            Rendering the Link doesn't imperatively navigate, use the Navigation component.

            You want to set additivity to false for your com.example logger. @AndyWilkinson is correct you're duplicating your logs, not your beans.

            How to list all consumers that are listening to an address on a vertex event bus?
            Asked 2022-Mar-29 at 14:13

            I have a vert.x program. I am creating a message consumer and attach it to listen on an address on the vertx event bus . later in the program I am unregistering that consumer . How do I know if the consumer is unregistered successfully ?

            following code snippet shows how i register a consumer on an address on vertex event bus



            Answered 2022-Mar-29 at 14:13

            As for the first question, you can safely assume consumer is unregistered successfully when res.succeeded() returns true inside unregister handler (as per your example).

            For the second part, afaik the event bus does not maintain the list of consumers registered to it, you have to maintain it yourself. The goal would be to have a map or some other collection where you store references for consumers when you register them with .consumer(...) method and remove them after unregister handler returns succeeded.

            I think this would be the issue you are referring to (with the advice by the lead architect of vertx): https://groups.google.com/g/vertx/c/d70YlHLL7KU?pli=1

            At the end, the issue was coming from a component (Notification) that was not properly registered.

            How do I implement a Logout functionality from a React Router Link to imports an array?
            Asked 2022-Mar-16 at 22:49

            I am trying to implement a logout functionality and am not sure what I need to do to implement it with my current set up. I was able to set up a Login functionality that pulls the correct profile data and once logged in, the Navbar + Dropdown Items are updated to display a link to logout. However, I am unsure of how I can add the logout functionality at the moment. I have been following guides but am stuck since nothing I am trying is working, once I hit a the logout link it links to /logout but fails to actually logout. The tutorial I am following claims I can do it via the frontend (I am using JWT).




            Answered 2022-Mar-16 at 22:46

            It seems you only need a Logout component that dispatches the logout action when it mounts, waits for the action to complete, and likely redirect back to a homepage or similar.

            How can I change this Navbar dropdown item to update from "Login" to "Logout" when a user logs in?
            Asked 2022-Mar-16 at 08:47

            I am trying to update my Navbar component so that when a user logs in, the navbar dropdown item "Login" changes to "Logout" but I am having issues. I am new to react and JS but learning as I go, so I apologize for any confusion in this question. I have jsx components for my Navbar, Dropdown, Footer, and for each page that a user wants to view which is rendered in my App.js file.

            only one child route displaying in react? displays component for a different route instead of its own
            Asked 2022-Mar-12 at 23:47

            When the user goes to the url for "/films/:title" it displays MovieDetailContainer which is the component for the path above it and doesnt display its own component. When I flip around the order of the urls the reverse happens. Why is this? I assume its a nesting error but I cant seem to figure it out.

            here is code for the routes and the code for the full App/js is below just incase.



            Answered 2022-Mar-12 at 23:47

            The two paths "/films/:id" and "/films/:title" have the same specificity, so the one rendered first will be the one that is matched and rendered by the Switch component.

            To resolve you need add something to differentiate them. I suggest a differentiating sub-path.

            Despite it is not a direct answer to your question... But

            Why do you need the conversion from flow to live data? Just subscribe to flow on ui layer and populate the flow with necessary livedata features. Believe me, this will make your life much more easier.

            I offer to do it by using implementation androidx.lifecycle:lifecycle-runtime-ktx:x.y.z and SharedFlow
