angular-routing This will end up compounding the number of data-load events that your application has to perform. Trending is based off of the highest score sort and falls back to it if no posts are trending. Sorry for the late reply, will this also work if it is in the app component? SO how do you do something so seemingly trivial as showing a different component based on a conditional? typescript And, there are some increased complexities around RxJS subscriptions and the view component life-cycle. angular2-forms primeng To be clear, when I say "conditional router outlet", what I mean is that I have a nested set of Views in which the inner View's directive is being rendered based on the conditions of the outer View's model. You can now choose to sort by Trending, which boosts votes that have happened recently, helping to surface more up-to-date answers. The right components are loaded but only for the two top routes. If this doesn't fit your logic, checkout the Angular Tutorial page to see the other guard types. java To get around this, I switched over to the ngRx Router, which worked beautifully. Or, would someone do that outside the router ? The Router destroys a routed component when it is no longer needed and the injected ActivatedRoute dies with it. The App component provides the navigation so that we can jump from route to route: There's not much going on in the App component. For that you should use Router from constructor. angular-reactive-forms Copyright var creditsyear = new Date();document.write(creditsyear.getFullYear());

If you go to the p1-c1 view, let it render the nested views, then click over to the p2-c1 view, and click your browser's back button before p2-c1 has a chance to full render, you get an Angular error: As you can see, not only did our Back-button operation get ignored but Angular 4 throws the error: My theory here is that when going from p1-c1 to p2-c2, Angular sees that the route pattern hasn't changed, only the parameters have. as per your recommendation, I have made that changes in app-routing.module.ts, https://github.com/saurabh47/Angular-routing-issue/tree/dev The reason this is working in non-prod mode, is that you have AOT compilation turned off for that mode. So I am not sure that this approach is at all supported in Angular generally. Do a simple conditional in a routes file.

Conditional routing is not working in prod build, while it works in the development mode. Or, perhaps, it's not fully correct. If a creature's best food source was 4,000 feet above it, and only rarely fell from that height, how would it evolve to eat that food? I have an extension of the Router outlet, and you can catch the route before being routed, I've added certain user rights in the RouteDefinitions, so I can check if the user is allowed.
