Ionic 4 Menu automatically opening when clicking link in other menu
I have 2 menu’s on a page. And they all work fine, except when I click on a link in my “side-menu” it closes that menu and loads the new page which is what its supposed to do but then it automatically opens my “mainMenu” on page load. Any idea why this menu is automatically opening after a link is clicked in the other menu?
app.component
<ion-app>
<ion-menu menuId="mainMenu" side="start" contentId="mainMenu" swipe-gesture="false">
<ion-header>
<ion-toolbar>
<ion-title>Pages Menu</ion-title>
</ion-toolbar>
</ion-header>
<ion-content>
<ion-list>
<ion-menu-toggle *ngFor="let p of appPages">
<ion-item [routerDirection]="'root'" [routerLink]="[p.url]">
<ion-icon slot="start" [name]="p.icon"></ion-icon>
<ion-label>
{{p.title}}
</ion-label>
</ion-item>
</ion-menu-toggle>
</ion-list>
</ion-content>
</ion-menu>
<app-side-menu></app-side-menu>
<ion-router-outlet id="mainMenu"></ion-router-outlet>
</ion-app>
side-menu.component
<ion-menu side="end" menuId="sideMenu" id="sideMenu" contentId="mainMenu" swipe-gesture="false">
<ion-header>
<ion-toolbar color="primary">
<ion-title>Steps</ion-title>
</ion-toolbar>
</ion-header>
<ion-content>
<div *ngFor="let p of menu">
<ion-item button *ngIf="p.children?.length > 0" (click)="p.open = !p.open" [class.active-parent]="p.open" detail="false">
<ion-icon slot="start" name="arrow-forward" *ngIf="!p.open">,/</ion-icon>
<ion-icon slot="start" name="arrow-down" *ngIf="p.open">,/</ion-icon>
<ion-label>{{ p.title }}</ion-label>
</ion-item>
<ion-list *ngIf="p.open">
<ion-menu-toggle>
<ion-item class="sub-item" *ngFor="let sub of p.children" [routerLink]="['/main', gameId, sub.steps_id]" routerDirection="root" [ngClass]="{'active': sub.steps_id==stepId}">
<ion-label>
{{ sub.name }}
</ion-label>
</ion-item>
</ion-menu-toggle>
</ion-list>
</div>
</ion-content>
</ion-menu>
and the page header where I display both menus
<ion-header>
<ion-toolbar>
<ion-buttons slot="start">
<ion-menu-button menu="mainMenu"></ion-menu-button>
</ion-buttons>
<ion-buttons slot="end">
<ion-menu-button menu="sideMenu"></ion-menu-button>
</ion-buttons>
<ion-title>
Home
</ion-title>
</ion-toolbar>

Draw over other Apps
Sure,
like facebook messenger. If facebook messenger will display over other apps in every where in the mobile with small chat head. like that my application also will show the icon. If i opened my application and redirect from my application to youtuve or maps throug my application only. So, my application is in back ground and maps will display in fore ground. In that maps also my own app icon will display aside like facebook messenger. which is in ionic4 only. refer image also provided below.
please help me out from this issue.
Thanks in Advance

Need advice for sharing business logic between multiple projects
So, after a great deal of reading, playground projects, and trial and error, none of the three options that @mikrochipkid proposed turned out to be appropriate, tl;dr: I need to share the business logic contained within Angular services specifically, where those three options go into advanced usage areas with creating services in the application in question to share data between components created with them.
As such, I am going to stick with Angular libraries for this task. Fortunately I can add a library project to my application’s workspace and move business logic around quite easily, from which point it’s simple to move the library project to a separate workspace and install it through NPM.
Either way, since this is an Angular-specific issue (i.e.: not directly related to Ionic), I’ll probably have better luck finding the info I need somewhere other than this forum.

HTTP Get Requests (Wordpress website Rest API calls) not working in iOS App
My guess is it’s likely a CORS issue and WKWebView. Do you have CORS setup on the wordpress api? Here’s a couple of posts that should help if that’s the problem.
The first explains CORS and Ionic by Josh Morony.
The second is enabling CORS on Wordpress. ***Make sure you read up on Access-Control-Allow-Origin and be careful on what you are allowing. Only allow the methods you need ie: GET.

Firebase storage on Ionic 4
Hey guys, I need some advice on where to store my information. Basically, I am building an essay app for my school to be published on the app/play store soon.
The thing is where can I store my essays and display it through my ionic 4 application?
Many people advise me to use firebase hence here comes another question, should I use realtime database or cloud firebase to store my essays?
Or is there another way to store my essays and display it on my app?
Please assist. Thank you so much

Realtime database in firebase in best but cloud firebase is new. And maybe will use in the future most. So you should use cloud firebase

HTTP Get Requests (Wordpress website Rest API calls) not working in iOS App
Thank you @caffic for responding. I have looked at the articles shared but it didn’t help. CORS is not an issue here as it is working fine when I run it in the browser and from Android device.
