Connecting Frontend with Backend: APIs & Fetch/Axios Now that you’ve learned about frontend frameworks, it’s time to understand how they communicate with backend services to fetch and send data. This is done using APIs (Application Programming Interfaces)…

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.

6. Next Steps

Now that you understand state management, the next essential topic is Backend Development with Node.js & Express.js—learning how to build powerful server-side applications.
