Ionic 4 now uses Angular router. Altough it still has its own NavControler, which helps to simulate push / pop navigation style though the navigateBackward and navigateForward methods.
So that ion-back-button is shown it is necessary to use navigateForward and navigateBackward, I think.
In my application I prefer to use routerLinks to navigate (so that the user can open the page in another tab) instead of navController.
But with routerLinks the ion-back-button does not appears. There must be an way to make routerLinks act like push/pop navigation.
How could I simulate an event like navigateForward and navigateBackward using routerLinks?
You can use the attribute routerDirection on your view element.
For example
<ion-button [routerLink]="['/details']" routerDirection="forward" >
Go forward
</ion-button>
For a full detailed description of how to manage navigation in Ionic 4 including routerLink you should read Josh's very detailed blog post
Moving from Ionic 3 to Ionic 4 with navigating has changed up quite a bit, but the changes aren't too bad. The Ionic Docs recommend to switch to Angular Routing instead of the traditional Ionic pop and push. There are a couple of way to route your pages, but I think the easiest to understand is using the navigateForward() and navigateBack() functions in the .ts file.
Ex.
navigateForward(){
this.navCtrl.navigateForward('/route of the page you want to navigate to');
}
<ion-button large block (click)="navigateForward()">
Navigate Forward
</ion-button>
Of course navigating forward and backward has to do with the structure of how your app is build from the stack.
The app-routing.module.ts file will automatically create the routes for your generated pages, but you can manually change the routes there as well as set a root page.
A good reference to routing tutorials here. Also shows different ways to navigate using routes throughout your app.
use routerDirection="back"
this will change the page transition like going back with your routerLink
#transition #ionic

I have a mobile app with Expo.
To move from one screen to the other, I use react-navigation's navigation.navigate(SCREEN_NAME)
I am building the web version of this app and would like my buttons to be links, instead of using navigate. This way, users will be able to open links in another tab.
I found out about useLinkProps, which works great but doesn't work with screen names.
I do not want to hardcode the urls in my code and would like to somehow compute them from the screen names.
For example, navigate("AddMessageScreen") might open the url /message/add or /profile/598/message/add based on your current route. I want to keep this automatic selection of the proper URL with useLinkProps.
Any idea how to achieve that?
To achieve this your will have first to configure links in react-navigation.
Not a trivial thing but it's well documented: configuring-links
Then you will have a url-like structure for all your routes that suites well for browser integration.
I'm attempting to design a project in Laravel. I ran the following command to initialize the project: "laravel new demo --jet". When prompted to choose between inertia and livewire I chose livewire as I've heard better things about it.
A little back story, I'm about 2-3 weeks into learning Laravel and I've never used livewire before, although I am very familiar with using Javascript and am very experienced with Vue.js. I've looked elsewhere for a solution to my problem but now I'm not quite sure if Laravel even supports exactly what I'm looking for.
TL/DR:
I'm wondering what the best practice would be for rendering child components on a page. I would like to create a dashboard that has several options to choose from on the left side of the page. When a user selects an option, I'd like for a corresponding component to appear in the center of the page. If a user were to select a different option, the original child component would disappear and a new corresponding child component would become visible.
Ideally, I'd like to avoid using the router for this, although that might just be because I'm not entirely comfortable with using it. I do understand it's pretty heavily integrated into the Laravel workflow. As I mentioned, I'm used to using Vue where you can easily integrate JS functionality into your html and use conditional statements to hide/show child components without changing routes.
If anything I've said above is causing any confusion, let me know. Thanks.
P.S. If anyone has any good resources for learning livewire & laravel together please let me know about them! Laracasts has been great but I think Laravel recently updated their auth scaffolding and it's causing some confusion for me.
I want to build a large application in Dart using material design. To accomplish this I included paper_elements into my project. My problem is, that I can't think of a good way to build my multi page application with paper_elements. Usually I create objects which would create their elements inline and add / remove themselves to the dom. The way I understand the paper_element tutorials I found so far this is not possible with them.
Is there a simple way to use paper_elements in dart while having an object based structure? For example I would have my application which loads either a register or login object and displays it in the browser. When logging in it should load a menu object which displays a menu and so on. All page changes should happen without a page reload.
I'm looking forward to all help, examples or links you could provide regarding my problem.
Cheers,
Tim
In Dart you normally build the app as SPA (single page application) without reload.
You can add remove a paper-element like normal DOM elements (div, input, ...) querySelector('#placeholder').append(new Element.tag('paper-input'));
You can also use <template if="{{}}"> or <template repeat="{{}}"> to make Polymer auto-insert these elements when certain conditions are fulfilled or for each value in a collection.
Your question isn't very specific but I guess all you need is already available here on SO as Q/A. Just search for [dart-polymer]. If you don't find anything just ask and we point you in the right direction.

The tutorials and example I've seen are all single page application.
Can anyone give an idea or point to a resource showing how a multiple page app can be developed with CanJS?
You should be able to create a new page in whatever app framework you are using or even just static pages, and then hookup your new control and view to any element on that new page.
You want to have a separate control for each module, so you might have separate controls even on a single page if you have, for example, a filterable dropdown list, a todo list, and a login. So, in your canjs directory for your app you will have separate sub-directories for each module which will contain your control, view/s, model/s, and observe/s and unit tests. This makes them re-usable, easier to test, and since they are modular if one part of your app breaks it won't take down all functionality. Once you get the hang of that incorporate AMD style loading of your assets with stealJS which is made by Bitovi - the CanJS creators.

If you want to manipulate the location.hash without actually changing pages or manaage browser history and client state you should check out can.route:

I wish to create a drag and drop feature for adding profile picture using CakePHP. Are there any samples which I can follow or a step by step guide?
I sourced many samples online but none of them cater for CakePHP.
I basically need a simple drag n drop for users to drag their profile image and the URL of the image is reflected in the database. The user will be able to edit another profile image. What approach should I use for this?
what you want to do is mostly about front-end, the back-end is generic server handling (in this case, PHP upload handling) and has little to do with Cake. That's why you don't see a specific cake tutorial for this. So, look up jquery drag drop and ajax upload. You'll also need to understand Cake rather well (well enough to adapt those online sample code to your Cake app).
I recommend you to use jQuery UI's draggable and droppable interactions.
Integrating them in CakePHP is quite easy, just follow the manual instructions to include Javascript files in a CakePHP application.
Finally, updating the database to reflect the URL of the image can be easily done with jQuery as well, using the AJAX related methods (e.g. post).
