What are some examples of CRUD operations using NgRx Entity?

Can you provide some examples of CRUD operations using NgRx Entity?

Sure! NgRx Entity simplifies managing collections of entities in your store. For example, to add an entity, you can use the addOne method.

How do I update an entity in the store?

You can update an entity using the updateOne method, where you provide the entity's ID and the changes you want to make.

What about deleting an entity?

To delete an entity, you can use the removeOne method, passing in the ID of the entity you want to remove.

Can you show me a complete example of these operations?

Absolutely! Here's a simple example:

import { EntityState, createEntityAdapter } from '@ngrx/entity';

export interface MyEntity {
  id: number;
  name: string;
}

export const adapter = createEntityAdapter<MyEntity>();

const initialState: EntityState<MyEntity> = adapter.getInitialState();

// Adding an entity
adapter.addOne({ id: 1, name: 'Entity 1' }, initialState);
// Updating an entity
adapter.updateOne({ id: 1, changes: { name: 'Updated Entity 1' } }, initialState);
// Removing an entity
adapter.removeOne(1, initialState);

This code demonstrates adding, updating, and removing entities.
