What is the best way to preserve the state of a component in Angular?

I need to find a way to preserve the state of a data table within my Angular 7 & Typescript application.

It's essentially like saving the state of a browser tab.

When I navigate to another component and return to the one with the data table, how can I ensure that the state - such as any applied filters - is saved?

Answer №1

Consider incorporating a state management tool such as , or utilizing local storage for efficient storing and retrieving of filters.

Answer №2

One approach is to save the state in local storage. This allows you to check if the item exists in local storage when returning to the original page, and then reinitialize it if found.

Sample code snippet:

let data = {};
localStorage.setItem('settings', JSON.stringify(data));

While this method works for educational purposes, it may not be the most efficient solution for production use.

Answer №3

  1. Session storage
  2. Redux
  3. Observable, or ReplaySubject

The final choice is a two-way service, with the most preferable option likely being Redux.
