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.

Backend Development: Node.js & Express.js

1. What is Node.js?

Node.js is a JavaScript runtime environment that allows JavaScript to run on the server-side. It is asynchronous, non-blocking, and event-driven, making it efficient for handling multiple requests.

Why Use Node.js?

Fast & Scalable – Runs on the V8 engine for high performance.

Single Programming Language – Use JavaScript for both frontend and backend.

Rich Ecosystem – Access thousands of packages via npm (Node Package Manager).


2. Setting Up Node.js

1. Install Node.js and npm from nodejs.org.


2. Verify installation by running:

node -v 
npm -v


3. Initialize a Node.js project inside a folder:

mkdir backend-project && cd backend-project 
npm init -y

This creates a package.json file to manage dependencies.



3. What is Express.js?

Express.js is a minimal and fast web framework for Node.js that simplifies building web servers and APIs.

Why Use Express.js?

Simple API – Easily create routes and middleware.

Handles HTTP Requests – GET, POST, PUT, DELETE.

Middleware Support – Add functionalities like authentication and logging.


Installing Express.js

npm install express


4. Creating a Basic Server with Express.js

Import Express and create a web server.

Define routes to handle requests (e.g., /home, /users).

Start the server to listen on a specific port.


5. REST API with Express.js

A REST API handles CRUD operations:

GET → Fetch data

POST → Add data

PUT → Update data

DELETE → Remove data


You can create API endpoints to send and receive JSON data, making it easy to connect with frontend applications.


6. Middleware in Express.js

Middleware functions execute before the request reaches the route handler.

Built-in middleware → express.json() (parses JSON requests).

Third-party middleware → cors, helmet, morgan (for security & logging).


7. Connecting Express.js with a Database

Most applications need a database to store and manage data. Common choices include:

MySQL / PostgreSQL → Relational databases (SQL).

MongoDB → NoSQL database for flexible data storage.


Connecting to MongoDB

1. Install Mongoose (MongoDB library for Node.js):

npm install mongoose


2. Connect to MongoDB in your project and define models to store data efficiently.


8. Next Steps

Once your backend is set up, the next steps are:

Learn authentication (JWT, OAuth).

Build RESTful APIs with proper error handling.

Deploy your backend on AWS, Vercel, or Firebase.

✅ Axios (For Better API Calls) → axios.get("/api/data")
✅ Handling Authentication – Login & Signup using JWT

📚 Resources:
🔹 Using Fetch API
🔹 Axios Guide

📌 3. GraphQL (Optional but Useful)

GraphQL is an alternative to REST APIs, allowing more flexible data fetching.
