Learning Vue.js can be a rewarding experience as it is a progressive framework for building user interfaces. Here’s a structured guide to help you get started with Vue.js:
Step 1: Understand the Basics of Web Development
Before diving into Vue.js, ensure you have a good understanding of the basics of web development, including:
HTML: Learn the structure of web pages.
CSS: Learn how to style web pages.
JavaScript: Learn the basics of programming in JavaScript.
Step 2: Learn the Basics of Vue.js
Install Node.js:
Download and install Node.js from nodejs.org.
Install Vue CLI:
Create a New Vue Project:
cd my-vue-app
Run the Application:
This will start a development server and open your new Vue.js application in your browser.
Step 3: Understand the Project Structure
When you create a new Vue.js project, you’ll see the following structure:
âââ node_modules/
âââ public/
â âââ index.html
âââ src/
â âââ assets/
â âââ components/
â âââ views/
â âââ App.vue
â âââ main.js
âââ .gitignore
âââ babel.config.js
âââ package.json
âââ README.md
âââ vue.config.js
Step 4: Learn the Basics of Vue.js
Vue Instance:
The root Vue instance is created in src/main.js.
import App from ‘./App.vue‘;
Vue.config.productionTip = false;
new Vue({
render: h => h(App),
}).$mount(‘#app‘);
Single File Components:
Components in Vue.js are written in .vue files that encapsulate HTML, CSS, and JavaScript.
Example component src/components/HelloWorld.vue:
<template>
<div class=“hello”>
<h1>{{ msg }}</h1>
</div>
</template>
<script>
export default {
name: ‘HelloWorld‘,
props: {
msg: String,
},
};
</script>
<style scoped>
h1 {
font-weight: normal;
}
</style>
Template Syntax:
Interpolation, directives, and event handling.
<div>
<h1>{{ message }}</h1>
<input v-model=“message” />
<button @click=“showAlert”>Click me</button>
</div>
</template>
<script>
export default {
data() {
return {
message: ‘Hello, Vue.js!‘,
};
},
methods: {
showAlert() {
alert(this.message);
},
},
};
</script>
Step 5: Learn Vue.js Essentials
Components:
Creating reusable components and passing data using props.
<template>
<div>
<h2>{{ title }}</h2>
</div>
</template>
<script>
export default {
props: [‘title‘],
};
</script>
Directives:
Built-in directives like v-if, v-for, v-bind, and v-model.
<ul>
<li v-for=“item in items” :key=“item.id”>{{ item.name }}</li>
</ul>
Vue Router:
Set up routing for single-page applications.
Configure the router.
import Vue from ‘vue‘;
import Router from ‘vue-router‘;
import Home from ‘@/views/Home.vue‘;
import About from ‘@/views/About.vue‘;
Vue.use(Router);
export default new Router({
mode: ‘history‘,
routes: [
{ path: ‘/‘, component: Home },
{ path: ‘/about‘, component: About },
],
});
Use the router in your main.js.
import App from ‘./App.vue‘;
import router from ‘./router‘;
Vue.config.productionTip = false;
new Vue({
router,
render: h => h(App),
}).$mount(‘#app‘);
State Management with Vuex:
Vuex is a state management pattern + library for Vue.js applications.
Set up Vuex store.
import Vue from ‘vue‘;
import Vuex from ‘vuex‘;
Vue.use(Vuex);
export default new Vuex.Store({
state: {
count: 0,
},
mutations: {
increment(state) {
state.count++;
},
},
actions: {
increment({ commit }) {
commit(‘increment‘);
},
},
getters: {
count: state => state.count,
},
});
Use Vuex in your main.js.
import App from ‘./App.vue‘;
import store from ‘./store‘;
Vue.config.productionTip = false;
new Vue({
store,
render: h => h(App),
}).$mount(‘#app‘);
Step 6: Advanced Vue.js Concepts
Custom Directives:
Create your own custom directives.
inserted: function(el) {
el.focus();
},
});
Mixins:
Reuse logic across components.
created() {
console.log(‘Mixin hook called‘);
},
methods: {
logMessage() {
console.log(‘This is a mixin method‘);
},
},
};
Filters:
Format or transform data in the template.
if (!value) return ”;
value = value.toString();
return value.charAt(0).toUpperCase() + value.slice(1);
});
Step 7: Testing and Debugging
Unit Testing with Jest:
Vue CLI comes with Jest for unit testing.
End-to-End Testing with Cypress:
Vue CLI also supports Cypress for end-to-end testing.
npm run test:e2e

Step 1: Set Up the Development Environment
Install Node.js:
Download and install Node.js from nodejs.org.
Install Vue CLI:
Vue CLI is a command-line tool for scaffolding and managing Vue.js projects.
Step 2: Create a New Vue Project

import router from ‘./router‘;
Vue.config.productionTip = false;

router,
render: h => h(App),
}).$mount(‘#app‘);
Step 6: Create a Simple Application
Let’s create a simple to-do list application to understand how Vue.js works in a real-world scenario.
Create Components:
TodoList.vue:
<template>
<div>
<h1>Todo List</h1>
<ul>
<li v-for=“todo in todos” :key=“todo.id”>
{{ todo.text }}
<button @click=“removeTodo(todo.id)”>Remove</button>
</li>
</ul>
<input v-model=“newTodo” @keyup.enter=“addTodo” placeholder=“Add a todo” />
</div>
</template>
<script>
export default {
data() {
return {
todos: [
{ id: 1, text: ‘Learn Vue.js‘ },
{ id: 2, text: ‘Build a to-do list‘ },
],
newTodo: ”,
};
},
methods: {
addTodo() {
if (this.newTodo.trim() !== ”) {
this.todos.push({ id: Date.now(), text: this.newTodo.trim() });
this.newTodo = ”;
}
},
removeTodo(id) {
this.todos = this.todos.filter(todo => todo.id !== id);
},
},
};
</script>
<style scoped>
ul {
list-style-type: none;
padding: 0;
}
li {
display: flex;
justify-content: space-between;
padding: 0.5rem;
background: #f9f9f9;
margin-bottom: 0.5rem;
border-radius: 4px;
}
input {
width: 100%;
padding: 0.5rem;
margin-top: 1rem;
border: 1px solid #ccc;
border-radius: 4px;
}
</style>
Update App.vue:
Modify src/App.vue to include the new component.
<template>
<div id=“app”>
<TodoList />
</div>
</template>
<script>
import TodoList from ‘./components/TodoList.vue‘;
export default {
name: ‘App‘,
components: {
TodoList,
},
};
</script>
<style>
#app {
font-family: Avenir, Helvetica, Arial, sans-serif;
-webkit-font-smoothing: antialiased;
-moz-osx-font-smoothing: grayscale;
text-align: center;
color: #2c3e50;
margin-top: 60px;
}
</style>
Run the Application:
Run npm run serve and navigate to http://localhost:8080 to see your to-do list application in action.
Step 7: Learn More Advanced Vue.js Features
Custom Directives:
Create your own custom directives.
inserted: function(el) {
el.focus();
},
});
Mixins:
Reuse logic across components.
created() {
console.log(‘Mixin hook called‘);
},
methods: {
logMessage() {
console.log(‘This is a mixin method‘);
},
},
};
Filters:
Format or transform data in the template.
if (!value) return ”;
value = value.toString();
return value.charAt(0).toUpperCase() + value.slice(1);
});
Step 8: State Management with Vuex
Install Vuex:
Set Up Vuex Store:
Configure the Vuex store in src/store/index.js.
import Vue from ‘vue‘;
import Vuex from ‘vuex‘;
Vue.use(Vuex);
export default new Vuex.Store({
state: {
todos: [],
},
mutations: {
addTodo (state, todo) {
state.todos.push(todo);
},
removeTodo (state, id) {
state.todos = state.todos.filter(todo => todo.id !== id);
},
},
actions: {
addTodo ({ commit }, todo) {
commit(‘addTodo‘, todo);
},
removeTodo ({ commit }, id) {
commit(‘removeTodo‘, id);
},
},
getters:
{
allTodos: state => state.todos,
},
});
“`
Use Vuex Store in Components:
Modify TodoList.vue to use Vuex.
<template>
<div>
<h1>Todo List</h1>
<ul>
<li v-for=“todo in todos” :key=“todo.id”>
{{ todo.text }}
<button @click=“removeTodo(todo.id)”>Remove</button>
</li>
</ul>
<input v-model=“newTodo” @keyup.enter=“addTodo” placeholder=“Add a todo” />
</div>
</template>
<script>
import { mapState, mapActions } from ‘vuex‘;
export default {
data() {
return {
newTodo: ”,
};
},
computed: {
…mapState([‘todos‘]),
},
methods: {
…mapActions([‘addTodo‘, ‘removeTodo‘]),
addTodo() {
if (this.newTodo.trim() !== ”) {
this.addTodo({ id: Date.now(), text: this.newTodo.trim() });
this.newTodo = ”;
}
},
},
};
</script>
<style scoped>
ul {
list-style-type: none;
padding: 0;
}
li {
display: flex;
justify-content: space-between;
padding: 0.5rem;
background: #f9f9f9;
margin-bottom: 0.5rem;
border-radius: 4px;
}
input {
width: 100%;
padding: 0.5rem;
margin-top: 1rem;
border: 1px solid #ccc;
border-radius: 4px;
}
</style>
Update main.js:
Use the Vuex store in your main.js.
import Vue from ‘vue‘;
import App from ‘./App.vue‘;
import store from ‘./store‘;
Vue.config.productionTip = false;
new Vue({
store,
render: h => h(App),
}).$mount(‘#app‘);
