When your modal is open if users click the back button in the browser or use the back key on mobile devices,  your model will not automatically close. How to fix: when a pop event happens close opening modals. import { PlatformLocation } from '@angular/common'; this. platformLocation  .onPopState((event) => {     // close openning modals }); 3.

  For those who don't know what SEO is, SEO stands for Search Engine Optimization, it helps people discover your site through search engines like Google, Bing, ... Take a look at the below picture: To let search engines discover your site, you must let search engines know your site, for google you can use Google Search Console  but that's another topic, I assume search engines already know your site. The 3 most important factors are URL, title tag, and meta tag (description, keyword,...). Search engines will look for those 3 things (and many other factors) to compare with the search query and decide whether your site is relevant or not. Url Try to use meaningful URLs. For example, instead of using a URL like https://yoursite.com/products/1 use https://yoursite.com/products/iphone or even better https://yoursite.com/iphone . You can achieve this by configuring your rooting modules. To make slug URLs you can strip accents your product names and join them with a hyphen (-). For e...

Github of this  exmaple.  There are a lot of practical scenarios when you load a list of items then go to the detail of an item, when you hit the back button you don't want to reload the item list again. Angular provides you a method to do exactly that. With RouteReuseStrategy when you hit the back button it takes you right back to where you were before without reloading anything. Of course, you can choose to do this or not for any page and it super easy to set up. To do this you need to create a class implement RouteReuseStrategy from @angular/router. There are 5 methods you need to implement: shouldDetach, store, shouldAttach, retrieve, shouldReuseRoute. Let's take a closer look at these methods. shouldDetach shouldDetach ( route :  ActivatedRouteSnapshot ):  boolean When you go to the next page, this method will be trigged, it decides whether the current route (a page) should be detached. In other words, Angular takes a snapshot of it and saves it in memory ...
