Displaying a separate 404 not found page inside of a module in Angular



In my Angular application, I would like to have two separate Page Not Found pages.



In the app root, there is one in case the user goes something like: http://localhost:4200/xyz. This is fine.



However, I added one to my admin module which has an AuthGuard on it. If the user is logged in and navigates to http://localhost:4200/admin/xyz I would like them to go to my not found page within the admin module. For some reason they are getting logged out and redirected back to the Login page.



Please refer to the sample project below (attempt to go to /admin, login, then change the path to /admin/xyz and hit enter):
https://stackblitz.com/edit/angular-7tjyqx



Also, same thing happens with crisis-center which is not a protected module. Try going to /crisis-center/xyz and you will get redirected back to crisis-center instead of crisis - page not found

That is because services in angular (AuthService) are not shared as singletons for lazy-loaded modules. so every time you go to http://localhost:4200/admin/xyz directly from the address bar, a new service instance is created which sets isLogged to false and you are thrown to the Login page. However, if you log in and visit through
routerLink to http://localhost:4200/admin/xyz, you will get the no page



found and that is because you are inside same service instance of the module.





Excellent answer. So I can either stop lazy loading the modules so the entire app reloads each time or not be able to do it. Is it common to have a not found page within each separate module (feature of the system)? It seems like most people have one on the outer level, but the problem with that is my features have different looks and feels. So if a user is in the Admin feature I want the page not found to be inside that template, if the user is in another feature I want the page not found to be inside of that template. So is it basically not possible unless I stop lazy loading?

Firebase Auth - with Email and Password - Check user already registered

Clash Royale CLAN TAG #URR8PPP Firebase Auth - with Email and Password - Check user already registered I want to check when a user attempts to signup with createUserWithEmailAndPassword() in Firebase user Authentication method, this user is already registered with my app. createUserWithEmailAndPassword() 8 Answers 8 To detect whether a user with that email address already exists, you can detect when the call to createUserWithEmailAndPassword () fails with auth/email-already-in-use . I see that @Srinivasan just posted an answer for this. createUserWithEmailAndPassword () auth/email-already-in-use Alternatively, you can detect that an email address is already used by calling fetchSignInMethodsForEmail() (previous called fetchProvidersForEmail() ). fetchSignInMethodsForEmail() fetchProvidersForEmail() When the user trying to create an user with same email address, the task response will be "Response: The email address is already in use by another account." mFirebas

Clash Royale CLAN TAG #URR8PPP Dynamically update html content plain JS So I have a script bound in my index.html, which literally has to fetch an array of jsons from an api, then dynamically update my page when get response. But as a result I'm getting an as the only update of my page. here is my script fetch(url) .then((resp) => resp.json()) .then((resp) => resp.results.forEach(item => fetch(item.url) .then((response)=> response.json()) .then((response) => pokeArr.push(response)) .catch(console.log) ) ).catch(console.log) const filler = () => if(!pokeArr) return 0 pokeArr.map((i,j)=> return `<tr>$i.name</tr>` ) const pokeindex = () => document.getElementById('a').appendChild(document.createElement(filler())) pokeindex() When I'm consoling it, I can see in the console all the responses I get, so I'm at least doing the fetching part right. What's parberakan ? What's pokeArr ? – T.J. Crowder Aug 8 at 12

How to determine optimal route across keyboard

Clash Royale CLAN TAG #URR8PPP How to determine optimal route across keyboard I'm trying to automate the typing process in a video game. Players are given an on-screen QWERTY keyboard layout that they can navigate with the control stick (up, down, left, right) in order to select a letter to type. I was wondering if there was a module for Python (or some other resource I could explore) that would help my program find a path across the keyboard as it types each letter in a given message. In other words, if the first letter typed was "A" and the next letter was "B", the module would know that the program should move 1 space down on the keyboard and 4 spaces to the right. Currently, I have the program resetting to the "G" key after each letter is typed (allowing me to use fixed-directions as the program parses each character in the desired message). As you can imagine, this is quite inefficient and defeats the purpose of automating the typing in the fir
