Setting up Vue Router

Setting up Vue Router

To use Vue Router in our application, we need to create an instance of Vue Router and configure the routes. Here’s a basic example:

// main.js

import Vue from 'vue'

import App from './App.vue'

import VueRouter from 'vue-router'

import Home from './components/Home.vue'

import About from './components/About.vue'


const routes = [

{ path: '/', component: Home },

{ path: '/about', component: About }


const router = new VueRouter({



new Vue({


render: h => h(App)


Defining Routes

In the example above, we define two routes: the root path (“/”) is associated with the Home component, and the “/about” path is associated with the About component.

Navigation Links

We can create navigation links using the <router-link> component provided by Vue Router. Here’s an example:



<router-link to="/">Home</router-link>

<router-link to="/about">About</router-link>




Route Transitions

We can apply transitions to route components using Vue’s transition system. Here’s an example:



<transition name="fade">





<style scoped>

.fade-enter-active, .fade-leave-active {

transition: opacity 0.5s;


.fade-enter, .fade-leave-to {

Vuex is a state management library for Vue.js applications. It provides a centralized store that holds the state of your application and allows you to access and modify that state through actions and mutations.

Why Use Vuex?

Vuex is useful for managing the state of your application, especially when it becomes complex and needs to be shared across multiple components. Here are some reasons to use Vuex:

  • Centralized State: Vuex stores all the state of your application in a single place, making it easy to manage and access the data from any component.
  • Mutability Control: Vuex enforces a strict pattern for updating the state, which helps prevent unexpected changes and makes it easier to track and debug state changes.
  • Modular Structure: Vuex allows you to divide your store into modules, which helps organize and manage different parts of your application state separately.
  • Time Travel Debugging: Vuex integrates with the Vue Devtools extension, allowing you to easily inspect and debug the state changes over time, enabling better understanding and troubleshooting.

Core Concepts

There are a few core concepts to understand when working with Vuex:

  1. State: The single source of truth that represents the entire state of your application. The state can be accessed and modified using getters and mutations.
  2. Getters: Computed properties for retrieving data from the state. Getters are useful for transforming or filtering the state before using it in components.
  3. Mutations: Functions that modify the state. Mutations are synchronous and should be the only way to change the state in order to have a predictable state management flow.
  4. Actions: Functions that are responsible for performing asynchronous operations and then committing mutations to update the state. Actions can be used to fetch data from an API or perform complex logic before mutating the state.
  5. Modules: Vuex allows you to divide your store into modules, each with its own state, getters, mutations, and actions. Modules are useful for managing different parts of the application state separately.

Example Usage

Here’s a simple example of using Vuex to manage a counter:



import Vue from ‘vue’;

import Vuex from ‘vuex’;


export default new Vuex.Store({

state: {

counter: 0


mutations: {

increment(state) {

state.counter += 1;



actions: {

increment(context) {




getters: {

doubleCounter(state) {

return state.counter * 2;








In the example above, we define a store that contains a state with a counter. We also define mutations to increment the counter and actions to commit these mutations. In the App component, we use the mapState helper to map the counter state to a computed property and the mapGetters helper to map the doubleCounter getter. Finally, we use the mapActions helper to map the increment action to a method that can be called on button click.


Vuex is a powerful state management library for Vue.js applications. It provides a centralized store for managing the state and offers various features such as modules, time travel debugging, and strict mutability control. By using Vuex, you can easily scale your Vue.js projects and have a better control over the application state.

  • Minify and compress your JavaScript and CSS files to reduce their size and load time.
  • Use lazy loading for images and other assets to only load them when needed.
  • Avoid unnecessary re-rendering by using shouldComponentUpdate or optimizing computed properties.

2. Code Organization

Proper code organization is crucial for maintaining efficiency and readability in your Vue.js projects. Consider the following best practices:

  • Follow a consistent folder structure to keep your code organized and easily maintainable.
  • Separate your components into reusable and modular files to encourage code reusability and reduce duplication.
  • Group related components, styles, and assets together to improve code readability and organization.
  • Utilize a state management solution like Vuex to centralize data and simplify component communication.

3. Optimize Bundle Size

3. Optimize Bundle Size

Reducing your Vue.js project’s bundle size can significantly improve loading times. Consider the following strategies:

  • Use dynamic imports or code splitting to load only the necessary components when needed.
  • Optimize and bundle your assets using tools like Webpack or Rollup to eliminate unused code and reduce file sizes.
  • Lazy load non-critical libraries or plugins to reduce the initial bundle size.
  • Utilize tree shaking to eliminate unused code and optimize the final bundle.

4. Use Caching and CDN

Implementing caching and Content Delivery Networks (CDN) can drastically improve the loading speed and efficiency of your Vue.js projects:

  • Set caching headers to allow browsers to cache static assets, reducing server requests.
  • Utilize a CDN to distribute content geographically and reduce the load on your server.
  • Consider implementing client-side caching mechanisms like LocalStorage to store and retrieve data efficiently.

5. Optimize Network Requests

Efficiently managing network requests can greatly improve the performance of your Vue.js projects:

  • Minimize the number of requests by bundling or combining multiple requests into a single one.
  • Utilize HTTP caching and ETags to avoid unnecessary server requests.

Building efficient Vue.js projects involves optimizing performance, organizing code effectively, reducing bundle size, leveraging caching and CDNs, optimizing network requests, and keeping dependencies up to date. By following these best practices, you can ensure that your Vue.js projects deliver optimal performance and a smooth user experience.

Code Splitting

Code splitting is a technique used to divide your project’s code into smaller chunks, which can be loaded on-demand, rather than all at once. This can greatly improve the initial loading time of your application and optimize the overall performance.

Vue.js provides built-in support for code splitting through its official bundler, webpack. With webpack’s code splitting capabilities, you can define entry points in your application and dynamically load modules when needed. This allows you to break your application into smaller pieces and load only what is necessary for a particular route or component.

There are several ways to implement code splitting in Vue.js:

1. Router-based Splitting

Vue Router allows you to define routes that dynamically load the corresponding components. This can be achieved by using the import function provided by ECMAScript 6, which allows you to dynamically load modules.

Here’s an example of how you can use router-based splitting in Vue.js:

const Home = () => import('./components/Home.vue');

const About = () => import('./components/About.vue');

const Contact = () => import('./components/Contact.vue');

const routes = [

{ path: '/', component: Home },

{ path: '/about', component: About },

{ path: '/contact', component: Contact },


const router = new VueRouter({



In this example, the Home, About, and Contact components will be loaded only when their respective routes are visited.

2. Component-based Splitting

In addition to router-based splitting, you can also split components themselves into separate chunks. This can be useful when you have large components or components that are rarely used.

To split components, you can use the vue-cli-plugin-webpack-bundle-analyzer plugin, which integrates with webpack and provides insights into your bundle’s size and composition. This way, you can identify which components should be split to optimize your application’s performance.

3. Dynamic Imports

In some cases, you may want to manually import modules at runtime, rather than relying on routing or component splitting. Vue.js supports dynamic imports through the import() function, which returns a promise that resolves to the imported module.

Here’s an example of using dynamic imports in Vue.js:

export default {

data() {

return {

dynamicComponent: null



mounted() {

import('./components/DynamicComponent.vue').then(module => {

this.dynamicComponent = module.default;




In this example, the DynamicComponent.vue will be loaded when the component is mounted, and then assigned to the dynamicComponent data property.

Benefits of Code Splitting

  • Improved Performance: By loading only the required code for a specific route or component, code splitting can significantly improve the loading time and overall performance of your Vue.js application.
  • Reduced Bundle Size: Breaking your code into smaller chunks allows for more efficient resource utilization and reduces the size of the initial bundle, resulting in faster load times for your users.
  • Enhanced User Experience: With faster loading times, users can begin interacting with your application more quickly, leading to a smoother and more pleasant user experience.

In conclusion, code splitting is an essential technique for scaling up your Vue.js projects. By dividing your code into smaller chunks and loading them on-demand, you can optimize the loading time and overall performance of your application, ensuring a better user experience.

Lazy Loading

Lazy loading is a technique used to improve the performance of web applications by loading resources (such as JavaScript files, images, and CSS stylesheets) only when they are needed. Rather than loading all resources upfront when the page loads, lazy loading allows resources to be loaded on-demand, as the user interacts with the application.

In a Vue.js project, lazy loading can be implemented using dynamic import statements. This allows you to split your application code into separate chunks, which can be loaded asynchronously when needed.

To lazy load a component in Vue.js, you can use the built-in async component feature. Instead of providing the component directly to the `component` option in your route configuration, you can provide a function that returns a Promise. This function is responsible for asynchronously importing the component module.

// Example route configuration using lazy loading


path: '/dashboard',

component: () => import('./components/Dashboard.vue')


When the user navigates to the `/dashboard` route, the component will be loaded only when it is needed. This can significantly improve the initial loading time of your application, especially if you have large components or a complex dependency tree.

In addition to lazy loading components, you can also apply lazy loading to other types of resources, such as images or CSS stylesheets, using a similar approach. Instead of using the `import()` function, you can use the HTML “ tag or the `import()` function with CSS stylesheets to dynamically load these resources when needed.

Lazy loading is a powerful technique that can greatly improve the performance of your Vue.js projects, especially as they scale up in size and complexity. By loading resources on-demand, you can reduce the initial load time of your application and improve the user experience.

Server-Side Rendering

Server-side rendering (SSR) is the process of rendering the application’s user interface on the server-side before sending it to the client. This approach allows the server to generate the complete HTML content, including the initial state and markup, which can be then sent to the client as a fully rendered page.

Benefits of Server-Side Rendering

  • Improved performance: With SSR, the server can pre-render the HTML content and send it to the client, reducing the time required to load and render the page on the client-side. This can result in faster initial page loads and improve the overall user experience.
  • Improved SEO: Search engine crawlers can easily parse and index the server-rendered HTML content, leading to better search engine visibility and improved SEO rankings.
  • Better user experience: Since the server sends a fully rendered page to the client, users can see the content of the page even before the JavaScript assets are loaded and executed. This can prevent blank screens or flash of unstyled content (FOUC) that can occur when using client-side rendering (CSR) alone.

Implementing Server-Side Rendering with Vue.js

Vueder, a popular server-side rendering (SSR) framework for Vue.js, provides an easy way to implement server-side rendering for Vue.js applications. It integrates with existing Vue.js projects and supports many Vue.js features and libraries.

To implement SSR with Vueder, you need to:

  1. Install Vueder via npm or yarn.
  2. Create a server entry file that configures the SSR renderer and handles the incoming requests.
  3. Configure your existing Vue.js project to support SSR by adding a webpack configuration for server-side rendering.
  4. Modify your project’s entry file to conditionally render the app on the server-side or client-side based on the environment.
  5. Build and start the server-side rendering application.

Vueder simplifies the process of server-side rendering by providing a set of APIs and tools that integrate seamlessly with Vue.js applications. It handles the rendering, hydration, routing, and state management aspects of server-side rendering, allowing developers to focus on building their application’s views and components.


Server-side rendering is a powerful technique that can improve performance, SEO, and user experience in Vue.js applications. By rendering the HTML content on the server-side before sending it to the client, SSR can reduce the time required to load and render the page, improve search engine visibility, and prevent blank screens or FOUC. Vueder provides an easy and efficient way to implement server-side rendering in Vue.js projects, making it a valuable tool for scaling up Vue.js applications.

Performance Optimization

Performance optimization is essential for any Vue.js project to ensure that it runs smoothly and efficiently. Here are some techniques and best practices to help optimize the performance of your Vue.js application:

1. Minimize Network Requests

Reducing the number of network requests your application makes can significantly improve performance. Combine multiple scripts and stylesheets into single files using tools like Webpack to minimize the number of requests made to the server. Additionally, consider lazy loading components or resources that are not immediately required, so they are only loaded when needed.

2. Use Component Level Code Splitting

Code splitting allows you to load only the necessary components on demand, reducing the initial load time of your application. Split large components into smaller, reusable pieces and dynamically import them when needed. This can be achieved using Vue’s built-in code splitting strategies or tools like Webpack.

3. Optimize Rendering Performance

Vue.js provides several techniques for optimizing rendering performance. Avoid unnecessary re-renders by using the v-once directive for static content. Utilize the v-if directive instead of v-show for conditional rendering, as it completely removes the component from the DOM. Additionally, consider using virtual scrolling or pagination to reduce the number of elements rendered at once.

4. Implement Caching and Memoization

Caching and memoization can significantly improve the performance of your Vue.js application. Cache frequently accessed data or API responses to avoid unnecessary AJAX requests. Implement memoization techniques to avoid repetitive computations and improve the efficiency of data retrieval or manipulation operations.

5. Optimize Vue Directives

Vue directives play a vital role in the performance of your application. Optimize the usage of directives by minimizing the number of times they are executed and avoiding complex logic inside them. Consider using the v-cloak directive to hide uncompiled template code before Vue takes over, preventing unnecessary flickering of the content.

6. Utilize Vue Devtools for Performance Analysis

Vue Devtools is a powerful browser extension that allows you to inspect and analyze the performance of your Vue.js application. Use it to identify performance bottlenecks, unnecessary re-renders, and track component lifecycles. Use the profiling feature to analyze the rendering time of different components and optimize accordingly.

7. Optimize Bundle Size

Reducing the size of your application’s JavaScript bundle can significantly improve the initial load time. Minify and compress your JavaScript and CSS files to reduce their size. Remove any unused dependencies or code to further optimize the bundle size. Consider using tools like Webpack Bundle Analyzer to visualize the composition of your bundle and identify redundant or large modules.

8. Profile and Optimize Critical Path

Identify the critical path of your application, which includes the resources and components required for the initial render. Profile this critical path to identify any performance bottlenecks and optimize accordingly. Avoid blocking JavaScript or CSS that delays the rendering process and optimize the loading of critical resources, such as fonts and images.

9. Benchmark and Measure Performance

Regularly benchmark and measure the performance of your Vue.js application to track improvements and identify areas that need further optimization. Use tools like Lighthouse, Google PageSpeed Insights, or WebPageTest to analyze the performance metrics, such as load time, time to interact, and first meaningful paint. Continuously monitor and optimize these metrics to ensure a smooth user experience.

10. Implement Server-Side Rendering (SSR)

If performance is a critical concern, consider implementing server-side rendering (SSR) for your Vue.js application. SSR delivers fully rendered HTML to the client, reducing the initial load time and improving SEO. It can be challenging to set up, but Vue.js provides tools like Nuxt.js that simplify the process of implementing SSR.

By following these performance optimization techniques and best practices, you can ensure that your Vue.js application is highly efficient and delivers a fast and smooth user experience.
