Vue2 vs Vue3 Differences

Vue3 has improved a lot over Vue2. It offers better performance and new features like the Composition API. Knowing these differences helps you choose the right version for your project.

Setting Up Your Development Environment

To start working with Vue.js, you need to set up your environment.

Required Tools and Extensions

You’ll need Node.js, npm or yarn, and a code editor like Visual Studio Code with Vue.js extensions.

Your First Vue Application

Creating your first Vue application is easy.

Hello World Example

Here’s a simple “Hello World” example to get you started:


<template>
<div>Hello World!</div>
</template>

<script>
export default {
name: ‘HelloWorld’
}
</script>

Core Vue.js Fundamentals

Understanding Vue.js basics is key to making apps that work well and are easy to update. Learning Vue.js means grasping its main ideas. These ideas help developers make strong and growing apps.

Vue Instance and Lifecycle

The heart of any Vue app is the Vue instance. It starts when you make a new Vue object.

Creating a Vue Instance

To start a Vue app, you pass an options object to the Vue constructor. This object can have data, computed stuff, methods, and lifecycle hooks.

Understanding Lifecycle Hooks

Lifecycle hooks are special functions that run at different times in a Vue component’s life. They let developers run code at specific times, like when the component is first shown or updated.

Template Syntax and Directives

Vue’s template syntax is a big deal. It lets developers show data on the page easily. Directives add extra stuff to HTML tags.

Text Interpolation and Attributes

Text interpolation uses double curly braces {{ }}. Attribute binding is done with the v-bind directive.

Conditional Rendering and List Rendering

For conditional stuff, use v-if and v-else. For lists, v-for is the way to go.

Data Binding and Reactivity

Data binding is a big part of Vue. It keeps the data and view in sync.

One-way vs Two-way Binding

One-way binding uses v-bind. Two-way binding is with v-model. Knowing the difference is key for handling form inputs and interactive stuff.

Component-Based Architecture

Using component-based architecture is key to getting the most out of Vue.js. It lets us break down complex interfaces into smaller, reusable parts.

### Creating and Registering Components

Creating and Registering Components

Making components in Vue.js is easy. We can create a new Vue instance or use a single-file component. We can register components globally or locally.

#### Global vs Local Registration

Global vs Local Registration

Global registration makes components available everywhere in the app. Local registration limits them to the component they’re in. Local registration is generally considered a best practice because it keeps things organized and avoids clutter.

### Props and Custom Events

Props and Custom Events

Components talk to each other with props and custom events. Props let parents send data to children. Custom events let children tell parents about changes or actions.

#### Prop Validation and Default Values

Prop Validation and Default Values

Vue.js makes it easy to check props and set default values. This ensures components get the data they need. For example:

Vue.component('example', {
props: {
propA: {
type: Number,
required: true
},
propB: {
type: String,
default: 'default value'
}
}
})

### Component Communication Patterns

Component Communication Patterns

Good communication between components is key for a smooth app. Vue.js has several ways to do this, like parent-child, event bus, and provide/inject.

#### Parent-Child Communication

Parent-Child Communication

This method is simple. Parents send data to children with props, and children send back with custom events.

#### Event Bus and Provide/Inject

Event Bus and Provide/Inject

For more complex needs, an event bus helps. The provide/inject method is also great for sharing data without passing props manually.

By learning these component-based architecture tips, we can make Vue.js apps better. They’ll be easier to maintain, grow, and work efficiently.

Vue CLI and Project Structure

Vue CLI makes setting up and managing projects easier. It’s a tool that helps developers create and configure Vue.js projects quickly. This way, you can focus more on building your app.

Installing and Using Vue CLI

To use Vue CLI, first install it globally. You can do this with npm or yarn by typing npm install -g @vue/cli or yarn global add @vue/cli. After that, start a new Vue.js project with vue create project-name.

Creating Projects with Vue CLI

When you create a project, Vue CLI guides you through a series of prompts. You can choose a preset, select features like TypeScript, and pick a linter. This makes setting up your project easy and customizable.

Project Configuration Options

Vue CLI lets you customize your project through the vue.config.js file. Here, you can change the output directory, public path, and more.

Vue Config File Customization

By editing the vue.config.js file, you can adjust the build process. You can change the public path, tweak webpack settings, and enable or disable features.

Best Practices for Project Organization

Keeping your project organized is key for easy maintenance and growth. Vue CLI offers a good starting point, but you can adjust it. Make sure your components, views, and assets are well-organized.

Folder Structure Recommendations

• Store components in src/components.
• Use src/views for top-level route components.
• Place static assets in src/assets.
• Put API service files in src/services.

Form Handling in Vue.js

Effective form handling is key for making Vue.js apps user-friendly. Forms are essential in many web apps. Vue.js makes handling them easy.

Basic Form Inputs and v-model

The v-model directive in Vue.js makes form handling simple. It creates a two-way data binding. This means changes in the input are shown in the component’s data, and vice versa.

You can use v-model with text inputs, checkboxes, and select menus. It helps capture user input well.

Input Modifiers and Custom Components

Vue.js has input modifiers for v-model to change its behavior. For example, .lazy updates data only after pressing Enter or clicking away.

Custom components can use v-model by defining a model property and an event. This updates the parent component’s data.

Form Validation with Vuelidate

Form validation is vital for ensuring user input meets expectations. Vuelidate is a popular library for Vue.js that makes this easy.

Setting Up Validation Rules

Vuelidate lets you set validation rules for fields with a simple syntax. You can check for email formats, required fields, and length limits.

Advanced Validation with VeeValidate

VeeValidate is another top library for Vue.js. It offers advanced features like field-level and form-level validation.

Field-Level vs Form-Level Validation

Field-level validation checks each field as the user interacts. It gives immediate feedback. Form-level validation checks the whole form on submission. It’s good for complex validation involving many fields.

By learning form handling and validation in Vue.js, developers can build strong, user-friendly apps. These apps follow vue.js best practices and improve the user experience.

Routing with Vue Router

Vue Router is the top choice for routing in Vue apps. It helps developers build complex and strong routing systems. Knowing how to set up Vue Router, configure routes, and use route guards is key for making dynamic and responsive Vue.js apps.

Setting Up Vue Router

To use Vue Router, we first install it in our project. This is done with a simple command in the terminal.

Installation and Basic Configuration

Installing Vue Router is easy with npm or yarn. After installing, we configure Vue Router by creating a router instance and adding it to our Vue app.

// Importing the necessary dependencies
import { createRouter, createWebHistory } from 'vue-router'
import Home from './views/Home.vue'

// Defining routes
const routes = [
{
path: '/',
name: 'Home',
component: Home
}
]

// Creating the router instance
const router = createRouter({
history: createWebHistory(process.env.BASE_URL),
routes
})

export default router

Route Configuration and Navigation

Setting up routes means defining paths and components for each path. Vue Router also supports named routes and navigating programmatically.

Named Routes and Programmatic Navigation

Named routes make it easier to navigate to specific routes. We can use the `$router.push` method to go to a named route.

For example:

// Navigating to a named route
this.$router.push({ name: 'Home' })

Route Guards and Dynamic Routing

Route guards decide if a route can be activated or not. They are key for adding authentication and authorization to our apps.

Route Params and Query Parameters

Vue Router supports dynamic routing with route and query parameters. Route parameters capture values in the URL path, while query parameters capture the query string.

Mastering Vue Router lets us build complex, robust, and user-friendly routing systems in our Vue.js apps.

State Management in Vue Applications

State management is key in Vue.js development. It helps developers handle complex application states well. As apps grow, managing state gets harder.

Local State vs. Global State

Knowing the difference between local and global state is vital. Local state is for a single component. Global state is shared by many components.

When to Use Each Approach

Use local state for simple, isolated components. It’s when the state doesn’t need to be accessed elsewhere. Global state is needed when many components share and sync data. The choice depends on the app’s complexity and needs.

Vuex: Actions, Mutations, and Getters

Vuex is a top choice for managing global state in Vue.js. It has actions for changing state, mutations for updating it, and getters for getting state in a computed way.

Implementing Vuex Modules

As apps grow, Vuex modules help. They break down the store into smaller, easier-to-manage modules. Each module has its own state, mutations, actions, and getters, making big apps easier to handle.

Pinia: The New Vue Store

Pinia is the top pick for Vue.js state management. It has a simpler API than Vuex. It makes managing global state easier with less code.

Migrating from Vuex to Pinia

Pinia makes it easy for Vuex users to switch. Its compatibility with Vuex and simpler syntax make it great for both new and old projects.

In summary, good state management is essential for strong, scalable Vue.js apps. Understanding local and global state and using tools like Vuex and Pinia helps developers make better apps.

API Integration and Data Handling

In Vue.js development, mastering API integration is key for interactive apps. We’ll learn how to make HTTP requests with Axios and integrate GraphQL with Apollo. We’ll also cover handling errors and loading states.

Making HTTP Requests with Axios

Axios is a top choice for HTTP requests in JavaScript apps. To use Axios in our Vue.js app, we first install it via npm or yarn.

Setting Up Axios Interceptors

Setting Up Axios Interceptors

Axios interceptors let us catch requests or responses before they reach the app. This is great for adding headers, handling errors, or logging requests.

GraphQL Integration with Apollo

Apollo Client is a powerful tool for managing data with GraphQL. It works well with Vue.js, making data handling easy.

Queries and Mutations in Vue

With Apollo, we can do GraphQL queries and mutations in Vue components. We set up Apollo Client and use useQuery and useMutation composables.

Error Handling and Loading States

It’s important to handle errors and loading states well for a good user experience. We check our request states and show feedback to users.

Implementing Retry Logic

Adding retry logic for failed requests makes our app more reliable. Axios and Apollo both help with this.

Mastering the Composition API

Vue.js is always changing, and learning the Composition API is key for developers. It brings a new way to manage state and side effects. This makes apps more robust and easy to grow.

Composition API vs. Options API

The Composition API is different from the Options API. The Options API groups code by component parts. But the Composition API organizes code by what it does. This makes code easier to understand and update.

When to Use Each Approach

For simple components, the Options API is good. It’s easy to use. But for complex apps, the Composition API is better. It handles complex logic well.

Reactive References and Computed Properties

Reactive references and computed properties are key in the Composition API. Reactive references (ref) make state reactive and easy to share. Computed properties update automatically when their inputs change.

Ref vs Reactive

Ref is for simple values, while reactive is for objects. Knowing when to use each is important for managing state well.

Composables and Code Organization

Composables are reusable functions that make code easy to share. They’re a big part of the Composition API. They help organize and reuse code better.

Creating Reusable Composables

To make a composable, find a piece of logic you can reuse. Put it in a function and return what’s needed. This keeps components simple and focused.

Learning the Composition API is vital for making Vue.js apps better. It helps with state, computed properties, and composables. This knowledge keeps developers up-to-date with Vue.js best practices.

UI Libraries and Design Systems

UI libraries and design systems are key to making Vue.js apps look good and consistent. They offer pre-made components and design rules. This lets developers focus on the app’s logic, not on designing everything from scratch.

Integrating Vuetify

Vuetify is a top choice for Vue.js UI. It sticks to Material Design. It has many components, from simple buttons to complex data tables.

Material Design Components

Vuetify makes apps look modern and consistent. It has:

• Pre-designed components that follow Material Design
• Customizable themes for your app’s look
