Basic Example# Computed properties allow us to declaratively compute derived values. However, there are cases where we need to perform "side effects" in reaction to state changes - for example, mutating the DOM, or changing another piece of state based on the result of an async operation. With Options API, we can use the watch option to trigger a function whenever a reactive property changes: ex..

// action from one moduleA to moduleB dispatch('moduleB/actionName', parameters, { root:true }) //Then it look for the action name and execute the command

Due to using a single state tree, all states of our application are contained inside one big object. However, as our application grows in scale, the store can get really bloated. To help with that, Vuex allows us to divide our store into modules. Each module can contain its own state, mutations, actions, getters, and even nested modules - it's fractal all the way down: const moduleA = { state: (..

Actions are similar to mutations, the differences being that: Instead of mutating the state, actions commit mutations. Actions can contain arbitrary asynchronous operations. Let's register a simple action: const store = createStore({ state: { count: 0 }, mutations: { increment (state) { state.count++ } }, actions: { increment (context) { context.commit('increment') } } }) Action handlers receive..

The only way to actually change state in a Vuex store is by committing a mutation. Vuex mutations are very similar to events: each mutation has a string type and a handler. The handler function is where we perform actual state modifications, and it will receive the state as the first argument: const store = createStore({ state: { count: 1 }, mutations: { increment (state) { // mutate state state..

Sometimes we may need to compute derived state based on store state, for example filtering through a list of items and counting them: computed: { doneTodosCount () { return this.$store.state.todos.filter(todo => todo.done).length } } If more than one component needs to make use of this, we have to either duplicate the function, or extract it into a shared helper and import it in multiple places ..

Where there is multiple state inside our component state, we use them. export default { data() { return { } }, computed: mapState({ students: state => state.students }), async created() { } }; When a component needs to make use of multiple store state properties or getters, declaring all these computed properties can get repetitive and verbose. To deal with this we can make use of the mapState h..

If you are having the issue that the time for loading and building vue-cli is too long, you are probably trying to run the command in Windows system. This will dramatically increase your time since it goes from Linux System to Windows System. And WSL2 CANNOT sense the change in the file So go to your LINUX system and do the vue create sample-project cd sample-project npm install npm run serve Th..
