Easy way to transfer a property value from TypeScript file of one component to another

first-component.ts

detailsList=[
  {
    text: value, icon: image
  },
  {
    text: value, icon: image
  }
]

second-component.html

<p>{{detailsList.text}}</p>

Can this be easily achieved?

Answer №1

To easily implement this functionality, you can create a service in a straightforward manner.

Start by building a service with a string variable.

import { Injectable } from '@angular/core';

@Injectable()
export class SimpleService {
   public text: string = '';

   constructor() { }
}

Next, import the service into your Module and include it as a provider.

import { ComponentA } from './component-a.ts';
import { ComponentB } from './component-b.ts';
import { SimpleService } from './simple.service.ts';

@NgModule({
  declarations: [
    ComponentA,
    ComponentB
  ],
  imports: [
    ComponentA,
    ComponentB
  ],
  providers: [
      SimpleService
  ]

})
export class XYZModule { }

Then, one component will set the value while the other component reads it.

ComponentA

import { SimpleService } from './simple.service.ts';

constructor(private simpleService: SimpleService) { }

setText(text: string): {
    this.simpleService.text = text;
}

ComponentB

TS-file

import { SimpleService } from './simple.service.ts';

constructor(private simpleService: SimpleService) { }

HTML-file

<p>{{simpleService.text}}</p>

That's all there is to it.
