What are Vuex actions and getters?

Can you explain what Vuex actions and getters are?

Sure! Vuex actions are functions that can perform asynchronous operations and commit mutations. Getters are like computed properties for the store, allowing you to access state in a derived way.

How do I define an action in Vuex?

You define an action in the actions object of your Vuex store. It typically looks like this:

actions: {
  myAction({ commit }) {
    // perform async operation
    commit('myMutation', payload);
  }
}

What is the difference between actions and mutations?

The main difference is that actions can contain asynchronous code and can call multiple mutations, while mutations must be synchronous and are the only way to change the state.

Can you give an example of a getter?

Certainly! A getter might look like this:

getters: {
  completedTodos: (state) => {
    return state.todos.filter(todo => todo.completed);
  }
}
