Creating a global variable using Typescript in AngularJS components

Within my application, I have been utilizing components and a boostrapper. The main goal is to implement a datepicker that can set a global date variable. Despite exploring various options such as creating a service, utilizing rootscope, and researching solutions on stackoverflow, none of them seem to be effective.

How should I properly go about creating a shared global variable that can be accessed by all components?

Answer №1

Using a global variable to store state can be problematic due to difficulties in tracking mutations. For Angular 1.x, consider creating a service to manage and share data efficiently. While state management in web applications remains complex, starting with a basic approach like this can be beneficial.

angular
  .module('app', [])
  .controller('testController', function(testService) {
    console.log(testService.getDate());
  });


angular.module('app')
  .service('testService', function() {
    var date = new Date();

    function getDate() {
      return date;
    }

    function setDate(newDate) {
      date = newDate;
    }
});

This setup allows for easy reading and updating of the date value across various controllers or components. Feel free to reach out if you need a Typescript version of this solution! :)
