4. Vuex: State Management for Vue.js

Vuex is the official state management library for Vue.js, similar to Redux but designed specifically for Vue applications.

Example: Simple Counter Using Vuex

1️⃣ Install Vuex

npm install vuex

2️⃣ Create a Vuex Store

import { createStore } from "vuex";

const store = createStore({
state: { count: 0 },
mutations: {
increment(state) {
state.count++;
},
},
actions: {
increment({ commit }) {
commit("increment");
},
},
getters: {
getCount: (state) => state.count,
},
});

export default store;

3️⃣ Provide the Store in Vue App

import { createApp } from "vue";
import App from "./App.vue";
import store from "./store";

const app = createApp(App);
app.use(store);
app.mount("#app");

4️⃣ Use Vuex in a Component

<template>
<div>
<h2>Count: {{ count }}</h2>
<button @click="increment">Increment</button>
</div>
</template>

<script>
import { mapState, mapActions } from "vuex";

export default {
computed: mapState(["count"]),
methods: mapActions(["increment"]),
};
</script>

✔ Pros: Integrated into Vue, simple to use.
❌ Cons: Not needed for small projects.


5. Which State Management Should You Use?

Use Context API for small React projects that don't require complex state management.

Use Redux for large-scale React applications where managing global state is crucial.

Use Vuex if you're building a Vue.js application with shared state across components.
