In Angular, you can pass data from one component to another using various methods, depending on the relationship between the components. Here are some common ways to pass data between components:<\/p>\n\n\n\n

    \n
  1. Using Input Properties<\/strong>: If you have a parent-child component relationship, you can pass data from a parent component to a child component using input properties. Here’s how to do it:<\/li>\n<\/ol>\n\n\n\n
      \n
    • In the parent component, define a property and bind it to an input property in the child component.<\/li>\n\n\n\n
    • In the child component, use the @Input<\/code> decorator to receive the data. Parent Component:<\/li>\n<\/ul>\n\n\n\n
         \/\/ parent.component.ts\n   import { Component } from '@angular\/core';\n\n   @Component({\n     selector: 'app-parent',\n     template: `\n       <app-child [data]=\"message\"><\/app-child>\n     `,\n   })\n   export class ParentComponent {\n     message = 'Hello from Parent!';\n   }<\/code><\/pre>\n\n\n\n
      Child Component:<\/p>\n\n\n\n
         \/\/ child.component.ts\n   import { Component, Input } from '@angular\/core';\n\n   @Component({\n     selector: 'app-child',\n     template: `\n       <p>{{ data }}<\/p>\n     `,\n   })\n   export class ChildComponent {\n     @Input() data: string;\n   }<\/code><\/pre>\n\n\n\n
        \n
      1. Using Services<\/strong>: To share data between components that don’t have a direct parent-child relationship, you can use Angular services. Create a shared service and inject it into the components that need to exchange data.<\/li>\n<\/ol>\n\n\n\n
          \n
        • In the service, define a property or method to store or provide the data.<\/li>\n\n\n\n
        • Inject the service into the components that need to access or modify the data. Service:<\/li>\n<\/ul>\n\n\n\n
             \/\/ data.service.ts\n   import { Injectable } from '@angular\/core';\n\n   @Injectable({\n     providedIn: 'root',\n   })\n   export class DataService {\n     sharedData: string = 'Hello from Service';\n   }<\/code><\/pre>\n\n\n\n
          Components:<\/p>\n\n\n\n
             \/\/ component1.component.ts\n   import { Component } from '@angular\/core';\n   import { DataService } from '.\/data.service';\n\n   @Component({\n     selector: 'app-component1',\n     template: `\n       <p>{{ dataService.sharedData }}<\/p>\n     `,\n   })\n   export class Component1Component {\n     constructor(private dataService: DataService) {}\n   }<\/code><\/pre>\n\n\n\n
             \/\/ component2.component.ts\n   import { Component } from '@angular\/core';\n   import { DataService } from '.\/data.service';\n\n   @Component({\n     selector: 'app-component2',\n     template: `\n       <button (click)=\"updateData()\">Update Data<\/button>\n     `,\n   })\n   export class Component2Component {\n     constructor(private dataService: DataService) {}\n\n     updateData() {\n       this.dataService.sharedData = 'Data Updated';\n     }\n   }<\/code><\/pre>\n\n\n\n
            \n
          1. Using Route Parameters<\/strong>: If you want to pass data between components based on route navigation, you can use route parameters. Configure your routes to accept parameters and access them in your components.<\/li>\n<\/ol>\n\n\n\n
              \n
            • Define route parameters in your route configuration.<\/li>\n\n\n\n
            • Access route parameters in your component using the ActivatedRoute<\/code> service. Route Configuration:<\/li>\n<\/ul>\n\n\n\n
                 const routes: Routes = [\n     { path: 'product\/:id', component: ProductComponent },\n   ];<\/code><\/pre>\n\n\n\n
              Component:<\/p>\n\n\n\n
                 import { Component } from '@angular\/core';\n   import { ActivatedRoute } from '@angular\/router';\n\n   @Component({\n     selector: 'app-product',\n     template: `\n       <p>Product ID: {{ productId }}<\/p>\n     `,\n   })\n   export class ProductComponent {\n     productId: string;\n\n     constructor(private route: ActivatedRoute) {\n       this.productId = this.route.snapshot.params['id'];\n     }\n   }<\/code><\/pre>\n\n\n\n
