To ensure that any changes made to data are reflected automatically when viewing data in Angular 2

In the process of developing an Angular 2 application, I encountered a scenario that requires special attention. The data displayed on the view is fetched from an API, with certain fields being editable by the user. These modifications can be saved using API calls, and there is a feature for automatic refresh every 30 seconds to update the view with the latest data. The issue arises when a user makes changes to the editable fields but has not yet submitted them for saving, and the page auto refreshes resulting in the loss of the user's changes. My objective is to find a solution that allows the user's modified data to be saved before the auto refresh occurs, eliminating the need for the user to make the changes again following the refresh. I am seeking suggestions for an efficient way to implement this functionality.

Answer №1

To indicate a change in the user, you can simply create a variable within your component and set it to true when necessary. Your implementation would be as follows:

export class MyComponent implements DoCheck {
  isUserChanged: boolean;

  ngDoCheck() {
    this.isUserChanged = true;
    // Reset isUserChanged back to false as needed
  }
}

If isUserChanged is true, the view will not be updated with new data. Hopefully, this solution works for you.
