If you want to store data globally and access it throughout your application without using session variables, you can utilize the NgRx state management library. NgRx is based on Redux and provides a predictable state container for Angular applications. Here's an overview of how you can use NgRx to store and access data: Install NgRx: Begin by installing the necessary packages. You'll need @ngrx/store for the state management and @ngrx/effects if you plan to use side effects. Define the State: Create a state interface or class that represents the data you want to store globally. This state will define the structure and properties of your data. Create Actions: Define actions that represent the different operations or changes you want to make to your data. Actions are simple classes with a type property that describes the action being performed. Implement Reducers: Create reducers that handle the state changes based on the dispatched actions. Reducers are pure functions that take the current state and an action as input and return a new state. Set up Store Module: Create a module to configure the NgRx store. Import and configure the StoreModule.forRoot() method in your application's main module. Dispatch Actions: Dispatch actions from your components or services to trigger state changes. Actions can be dispatched using the store.dispatch() method, which will invoke the reducers and update the state accordingly. Select Data: Use selectors to access the stored data from any component or service. Selectors are functions that retrieve specific data from the global state. You can use the store.select() method to access the data and subscribe to changes. By following these steps, you can store data in the NgRx store, which acts as a global state container accessible throughout your application. This approach ensures that the data remains consistent and cannot be directly modified by users.
