How can I implement error notifications in Vuex?

You can implement error notifications in Vuex by creating a state property for errors and mutations to update it.

Can you show me a code example?

Sure! You can create a Vuex store like this:

const store = new Vuex.Store({
  state: {
    error: null
  },
  mutations: {
    setError(state, error) {
      state.error = error;
    },
    clearError(state) {
      state.error = null;
    }
  }
});

How do I trigger the error notification?

You can trigger it by committing the setError mutation when an error occurs, like this:

try {
  // some code that may throw an error
} catch (error) {
  store.commit('setError', error.message);
}

What about displaying the error message in the UI?

You can use a computed property to access the error state and display it in your component. For example:

computed: {
  errorMessage() {
    return this.$store.state.error;
  }
}
