Routing in Angular allows navigation between views. When you need to pass data during navigation, Angular\u2019s routing state comes in handy. Here’s a practical guide with example code and best practices.<\/p>\n\n\n\n

What is Routing State?<\/h2>\n\n\n\n

Angular’s Router allows passing state using the state<\/code> property in NavigationExtras<\/code>. This is useful for transferring temporary data.<\/p>\n\n\n\n

Step-by-Step Example<\/h2>\n\n\n\n

1. Define Routes<\/h3>\n\n\n\n

const routes: Routes = [ { path: 'home', component: HomeComponent }, { path: 'details', component: DetailsComponent } ];<\/code><\/p>\n\n\n\n

2. Navigate with State<\/h3>\n\n\n\n

this.router.navigate(['\/details'], { state: { productId: 123, productName: 'Angular Guide' } });<\/code><\/p>\n\n\n\n

3. Receive State<\/h3>\n\n\n\n

const navigation = this.router.getCurrentNavigation(); const state = navigation?.extras.state; if (state) { console.log('Product ID:', state['productId']); }<\/code><\/p>\n\n\n\n

Note:<\/strong> Data passed via router state is only available during initial navigation, and will be lost on page refresh.<\/p>\n\n\n\n

Best Practices<\/h2>\n\n\n\n
    \n
  • Use for short-lived data<\/li>\n\n\n\n
  • Use services for global state<\/li>\n\n\n\n
  • Use localStorage<\/code> or queryParams<\/code> for persistent data<\/li>\n<\/ul>\n\n\n\n

    Conclusion<\/h2>\n\n\n\n

    Routing state in Angular simplifies passing temporary data during component navigation. Use it wisely for transient data and pair it with more robust solutions when needed.<\/p>\n","protected":false},"excerpt":{"rendered":"
