What are some examples of NgRx selectors?
An example of an AI chatbot conversation about NgRx selectors and their usage in state management.
Can you give me some examples of NgRx selectors?
Sure! NgRx selectors are functions used to select slices of state from the store. For example, you can create a selector to get a list of users from the state.
How do I create a selector for a specific user by ID?
You can create a selector like this: createSelector(selectUsers, (users, props) => users.find(user => user.id === props.id)); This will return the user with the specified ID.
What is the difference between a simple selector and a memoized selector?
A simple selector just retrieves data from the state, while a memoized selector caches the result and only recalculates when the input state changes, improving performance.
