There are several ways to pass data between pages (or components) in Angular:

  1. Using a shared service: Create a service that holds the data and inject it into both components. The components can then use the service to access and update the shared data.
  2. Using a route parameter: Pass the data as a parameter in the route and retrieve it in the component using the ActivatedRoute service.
  3. Using the Angular route's data property: Use the data property of the route to pass data to the component. You can access the data in the component using the ActivatedRoute service.
  4. Using a store like ngrx or store.js: Use a centralized store to manage the state of the application and access the data from any component.
  5. Using local storage or session storage: Save the data in the browser's local storage or session storage, and retrieve it in the other component.


Which method you use will depend on the requirements of your application and the amount and type of data that needs to be shared.

There are different ways to pass data between pages in Angular, but some popular methods are:

  1. Query Parameters: You can pass data in the url using query parameters. For example, if you have a URL like /users?id=1&name=John, you can easily retrieve the id and name parameters in the target page using the ActivatedRoute service.
  2. Route Parameters: You can also pass data using route parameters. For example, if you have a URL like /users/:id, you can retrieve the id parameter in the target page using the ActivatedRoute service.
  3. Shared Service: You can create a shared service that holds your data and inject it in the components that need it. This is useful if you have a lot of data that needs to be shared between pages.
  4. Local Storage: You can save your data in the browser local storage and retrieve it in the target page. This can be useful if you need to save the data for a longer period of time or across sessions.
  5. State Management: You can use a state management library like NgRx to manage your application state and share data between pages. This is useful for complex applications with a lot of data and interactions between components.
