Sending data to child components in Ionic

I am currently utilizing Ionic's router-outlet to navigate between a parent page and three children pages:

parent.page.html

<ion-content>
    <ion-router-outlet></ion-router-outlet>
</ion-content>

parent-routing-module.page.ts

children: [
  {
    path: 'child-one',
  },
  {
    path: 'child-two',
  },
  {
    path: 'child-three',
  }
]

My goal is to send data from the parent page to each of the children pages during navigation using the router-outlet. What would be the best way to achieve this?

Answer №1

When it comes to handling Ionic routing, it is essentially managed by angular routing. Therefore, when seeking solutions for this issue, look towards angular for answers.

If the matter pertains to a child page, one common method is to transfer string data through the URL of the child page, like so:

children: [
      {
        path: 'child\:myVariable',
      }
    ]

In your child page, you can utilize the following code:

constructor(private route: ActivatedRoute) {
}
...
ngOnInit() {
    const myVar = this.route.snapshot.paramMap.get('myVariable');
}

Another approach is to leverage Angular services. These services are injected at the root level, making your data easily accessible throughout your application.
