I've been searching for a solution to this weird behavior with no luck.
- There are no errors in the angular 4 console or the javascript console
- Using Angular CLI (Angular 4)
I'm getting extremely weird behavior with the angular router. I'm attempting to load a child route, which has it's own module, from the parent AppModule. The route is at /products
At the /products module (products.module.ts): I have 3 routes:
- /products/overview
- /products/intro [redirected to from /products]
- /products/product/:product
The products module is supposed to have it's own navbar UNDER the global AppModule's navbar, which is above the router-outlet in the products.component.html component template.
The main problem: When I load the page (not using an angular routerLink) to /products:
- both navbars are visible
- the page that is LOADED (ex /intro) has the navbar visible, but the child component (IntroComponent) is NOT visible
- HOWEVER, when I navigate to any other subroute within the /products module routes, (ex /overview or /product/:product): it renders just fine. So whatever route is loaded on a full page refresh is not visible.
The weirdest part: When I LOAD the page (refresh) on a route that isn't /products (ex /home) and then use the main navbar to navigate to /products:
- The navbar is not visible ?????
- The sub component (ex /intro component) IS visible
This has been causing me a great deal of hell for the past few days.
Now, some code:
app.module.ts [main AppModule]

I'll also provide my package.json dependencies for versions, I'm using ng serve for testing.

This is my first 'looking for help' post on stackoverflow, so let me know if there's anything I can improve.
I've tried to research various forms and tutorials and referenced the angular docs for routing
Edit: Adding some pictures for more clarification of the situation
Home page: http://prntscr.com/gskex5
Products [/products/intro] (navigated to using routerLink): http://prntscr.com/gskf2h (the products navbar is missing) On refresh, the navbar becomes visible, but the intro component is gone: http://prntscr.com/gskfaq
However, when I click on another component in the products nav, it works properly: http://prntscr.com/gskfhf
if I refresh, the component disappears, and the nav is left: http://prntscr.com/gskfna and now, for whatever reason, if i go back to intro, it works properly: http://prntscr.com/gskfra
So basically, whatever route is loaded when the page is initially loaded, it has a problem [component is not visible]. If the initially loaded route is not /products; the product navbar is not visible.
.catchin yourrouter.navigatecall to see if the route is actually changing. It may also have something to do with your AuthGuard - Everest
