Step-by-step guide to creating a store in Angular using ngrx

In Angular, a store is typically created using a library called ngrx. Here are the general steps to create a store in Angular using ngrx:

1. Install ngrx: Run the following command in the terminal to install ngrx: npm install @ngrx/store
2. Create a store folder: Create a new folder called “store” in the root of the project and create a new file called “app.state.ts” in it. This file will contain the shape of the state for the entire application.
3. Define the state: In the “app.state.ts” file, define the shape of the state by creating an interface. For example, you can create an interface called “AppState” and define properties such as “todos” or “user” that you want to store in the state.
4. Create actions: In the store folder, create a new file called “actions.ts” and define the actions that can be performed on the state. For example, you can create actions such as “AddTodo” or “RemoveTodo” that can modify the state.
5. Create a reducer: In the store folder, create a new file called “reducer.ts” and define the function that will handle the actions and update the state. The reducer function takes in the current state and an action, and it returns the new state based on the action.
6. Add the store to the app: In the “app.module.ts” file, import the store module and add it to the imports array.
7. Use the store: In the component where you want to use the store, you can use the store by injecting the Store service from the ngrx/store module, and use the store.select() method to select the desired state and store.dispatch() to dispatch actions.
8. (Optional) : You can also use ngrx/effects to handle side effects like http calls, it’s a way of handling async actions.

Note that this is a high-level overview of creating a store in Angular using ngrx. Additional setup and configuration may be required depending on the specific requirements of your application.
